Stunted growth

Stunted growth, also known as stunting or linear growth failure, is defined as impaired growth and development manifested by low height-for-age.[1] It is a primary manifestation of malnutrition (or more precisely chronic undernutrition) and recurrent infections, such as diarrhea and helminthiasis, in early childhood and even before birth, due to malnutrition during fetal development brought on by a malnourished mother. The definition of stunting according to the World Health Organization (WHO) is for the "height-for-age" value to be less than two standard deviations of the median of WHO Child Growth Standards.[2] Stunted growth is usually associated with poverty, unsanitary environmental conditions, maternal undernutrition, frequent illness, and/or inappropriate feeding practice and care during early years of life.

Prevalence of stunting in children under 5 years by region (2020-2022)

As of 2020, an estimated 149 million children under 5 years of age, are stunted worldwide.[3] More than 85% of the world's stunted children live in Africa and Asia.[4] Once established, stunting and its effects typically become permanent. Stunted children may never regain the height lost as a result of stunting, and most children will never gain the corresponding body weight. Living in an environment where many people defecate in the open due to lack of sanitation, is an important cause of stunted growth in children, for example in India.[5]

Health effects edit

Stunted growth in children has the following public health impacts apart from the obvious impact of shorter stature of the person affected:

  • Greater risk for illness and premature death[2]
  • Delayed neurocognitive development and therefore poorer school performance and later on reduced productivity in the work force[2]
  • Reduced cognitive capacity
  • Future risk of obesity[6]
  • Women of shorter stature have a greater risk for complications during child birth due to their smaller pelvis, and are at risk of delivering a baby with low birth weight[2]
  • Stunted growth can be passed to the next generation, known as the "intergenerational cycle of malnutrition"[2]

The impact of stunting on child development has been established in multiple studies.[7] If a child is stunted at age 2 they will have higher risk of poor cognitive and educational achievement in life, with subsequent socio-economic and inter-generational consequences.[8][7] Multi-country studies have also suggested that stunting is associated with reductions in schooling, decreased economic productivity and poverty.[9] Stunted children also display higher risk of developing chronic non-communicable conditions such as diabetes and obesity as adults.[8][9] If a stunted child undergoes substantial weight gain after age 2, there is a higher chance of becoming obese. This is believed to be caused by metabolic changes produced by chronic malnutrition, that can produce metabolic imbalances if the individual is exposed to excessive or poor quality diets as an adult.[8][9] This can lead to higher risk of developing other related non-communicable diseases such as hypertension, coronary heart disease, metabolic syndrome and stroke.[8][9] At societal level, stunted individuals do not fulfill their physical and cognitive developmental potential and will not be able to contribute maximally to society. Stunting can therefore limit economic development and productivity, and it has been estimated that it can affect a country's GDP up to 3%.[8][7][9]

Stunting is highly prevalent in low- and middle income countries (LMICs) and has severe consequences including increased risk of infections,[10] mortality[11][12] and loss of human capital.[10][13] The global prevalence of stunting decreased from 33% to 23% between 2000 and 2016.[14] Meanwhile, 37% of children in South Asia are stunted, and due to a large population size, the region bears about 40% of the global burden of stunting.[15]

Causes edit

 
The prevalence of child stunting generally increases as cities become smaller and moving away from urban centres while child wasting and overweight are lower and exhibit less evident trends across the rural-urbann continuum.

In many publications, the causes for stunting are considered very similar if not the same as the causes for malnutrition in children. However, this is not uncontradicted. Recent evidence stresses that stunting may not be taken as a synonym of malnutrition,[16] but as the natural condition of human height in non-Westernized societies. [17]

Almost all stunting occurs within the 1,000-day period that spans from conception to a child's second birthday,[18][19] which constitutes a window of opportunity for growth promotion.[20] The recognition of pre-natal factors underlines the inter-generational aspects of growth,[21] and the need for early interventions.The three main causes of stunting in South Asia, and probably in most developing countries, are poor feeding practices, poor maternal nutrition, and poor sanitation. A recent risk assessment analysis for 137 developing countries found that the leading risk factors for stunting were fetal growth restriction (birth weight <10th centile) followed by unimproved sanitation and diarrhea. It was estimated that 22% of stunting cases were attributable to environmental factors while 14% were attributable to child nutrition.[22] In addition, looking at trends from 1970 to 2012 for 116 countries, women’s education, gender equality and finally quantity and quality of foods available at the country level have been instrumental in reducing stunting rates, while income growth and governance have played facilitating roles.[23]

Feeding practices edit

Inadequate complementary child feeding and a general lack of vital nutrients beside pure caloric intake is one cause for stunted growth. Children need to be fed diets which meet the minimum requirements in terms of frequency and diversity in order to prevent undernutrition.[24] Exclusive breastfeeding is recommended for the first six months of life and complementary feeding of nutritious food alongside breastfeeding for children aged six months to 2-years-old. Prolonged exclusive breastfeeding is associated with undernutrition because breast milk alone is nutritionally insufficient for children over six months old.[25][26] Breastfeeding in long time with inadequate complementary feeding leads to growth failure due to insufficient nutrients which are essential for childhood development. The relationship between undernutrition and prolonged duration of breastfeeding is mostly observed among children from poor households and whose parents are uneducated as they are more likely to continue breast-feeding without meeting minimum dietary diversity requirement.[27]

Maternal nutrition edit

Poor maternal nutrition during pregnancy and breastfeeding can lead to stunted growth of their children. Proper nutrition for mothers during the prenatal and postnatal period is important for ensuring healthy birth weight and for healthy childhood growth. Prenatal causes of child stunting are associated with maternal undernutrition. Low maternal BMI predisposes the fetus to poor growth leading to intrauterine growth retardation, which is strongly associated with low birth weight and size.[28] Women who are underweight or anemic during pregnancy, are more likely to have stunted children which perpetuates the inter-generational transmission of stunting. Children born with low birthweight are more at risk of stunting.[24] However, the effect of prenatal undernutrition can be addressed during the postnatal period through proper child feeding practices.[28]

Maternal undernutrition increases the risk of stunting at 2 years age.[18] Based on data from 19 birth cohorts from LMICs, 20% of stunting is attributed to being born small-for-gestational-age (SGA).[29] Further, estimated stunting at 2 years attributed to fetal growth restriction and preterm birth in 2011 was 33% in all developing countries and 41% in South Asia.[22] Restricted pre- and postnatal growth are in turn important determinants of short adult height,[30] increasing the likelihood of the next generation also being stunted.[31]

Sanitation edit

There is most likely a link between children's linear growth and household sanitation practices. The ingestion of high quantities of fecal bacteria by young children through putting soiled fingers or household items in the mouth leads to intestinal infections. This affect children's nutritional status by diminishing appetite, reducing nutrient absorption, and increasing nutrient losses.The diseases recurrent diarrhea and intestinal worm infections (helminthiasis) which are both linked to poor sanitation have been shown to contribute to child stunting.[citation needed]

Research on a global level has found that the proportion of stunting that could be attributed to five or more episodes of diarrhoea before two years of age was 25%.[32] Since diarrhoea is closely linked with water, sanitation and hygiene (WASH), this is a good indicator for the connection between WASH and stunted growth. To what extent improvements in drinking water safety, toilet use and good handwashing practices contribute to reduce stunting depends on the how bad these practices were prior to interventions.

Environmental enteropathy edit

The condition termed environmental enteropathy is proposed as an immediate causal factor of childhood stunting.[33][34] This is an asymptomatic small intestinal disorder characterized by chronic gut inflammation, reduced absorptive surface area, and disruption of intestinal barrier function.[35][36] This small bowel disorder is attributable to sustained exposure to intestinal pathogens caused by faecal contamination of food and water.[37][38][34] Recent evidence confirmed a causal relationship between stunted growth and environmental enteropathy in children.[39] Several studies are also underway to examine the link between this condition and stunted growth.[37][40][41] The exact pathogenesis of environmental enteropathy causing linear growth failure is unclear, but it is hypothesized that chronic inflammatory state and impaired absorption associated with this condition may inhibit bone growth and affect the linear growth during early years of life.[42]

Diagnosis edit

Growth stunting is identified by comparing measurements of children's heights to the World Health Organization 2006 growth reference population: children who fall below the fifth percentile of the reference population in height for age are defined as stunted, regardless of the reason. The lower than fifth percentile corresponds to less than two standard deviations of the WHO Child Growth Standards median.[citation needed]

As an indicator of nutritional status, comparisons of children's measurements with growth reference curves may be used differently for populations of children than for individual children. The fact that an individual child falls below the fifth percentile for height for age on a growth reference curve may reflect normal variation in growth within a population: the individual child may be short simply because both parents carried genes for shortness and not because of inadequate nutrition. However, if substantially more than 5% of an identified child population have height for age that is less than the fifth percentile on the reference curve, then the population is said to have a higher-than-expected prevalence of stunting, and malnutrition is generally the first cause considered.[citation needed]

Prevention edit

Three main things are needed to reduce stunting:[43]

  • a kind of environment where political commitment can thrive (also called an "enabling environment")
  • applying several nutritional modifications or changes in a population on a large scale which have a high benefit and a low cost
  • a strong foundation that can drive change (food security, and a supportive health environment through increasing access to safe water and sanitation).

To prevent stunting, it is not just a matter of providing better nutrition but also access to clean water, improved sanitation (hygienic toilets) and hand washing at critical times (summarised as "WASH"). Without provision of toilets, prevention of tropical intestinal diseases, which may affect almost all children in the developing world and lead to stunting will not be possible.[44]

Studies have looked at ranking the underlying determinants in terms of their potency in reducing child stunting and found in the order of potency:[23]

  • percent of dietary energy from non-staples (greatest impact)
  • access to sanitation and women's education
  • access to safe water
  • per capita dietary energy supply

Three of these determinants should receive attention in particular: access to sanitation, and diversity of calorie sources from food supplies. A study by the Institute of Development Studies has stressed that: "The first two should be prioritized because they have strong impacts yet are farthest below their desired levels".[23]

The goal of UN agencies, governments and NGO is now to optimise nutrition during the first 1000 days of a child's life, from pregnancy to the child's second birthday, in order to reduce the prevalence of stunting.[45] The first 1000 days in a child's life are a crucial "window of opportunity" because the brain develops rapidly, laying the foundation for future cognitive and social ability.[46] Furthermore, it is also the time when young children are the most at risk of infections that lead to diarrhoea. It is the time when they stop breast feeding (weaning process), begin to crawl, put things in their mouths and become exposed to faecal matter from open defecation and environmental enteropathies.[45]

Dietary interventions to improve stunting edit

Previous interventions to reduce stunting have shown modest effects. Multiple micronutrient supplementation shows only small benefits for linear growth[47] and results from studies supplementing lipid based nutrient supplements (LNS) to children are inconclusive.[48][49] Educational interventions to improve complementary feeding may achieve behavioral change but have no or small effects on growth.[50][51] Further, studies on the effect of micronutrient fortification, increased availability of key nutrients or increased energy density of complementary foods on stunting also show heterogenous results.[52] It is estimated that education interventions, if optimally designed and implemented, could reduce stunting by 0.6 z-scores while food-based interventions could reduce stunting by 0.5 z-scores,[52] which is moderate compared to the average global growth deficit.[53] Finally, the Lancet-series on maternal and child nutrition estimated that the impact of all existing interventions designed to improve nutrition and prevent related diseases in mothers and children, could reduce stunting at 3 years by merely 36%.[54] Hence, factors explaining the shortfall in observed associations between child feeding practices and nutrient intake and linear growth, have increasingly been the focus of scientific interest.[55]

Recent works showed promise that intervention with egg may improve linear growth in children.[56][57] Comprehensive intervention package containing eggs also found to be effective in improving linear growth in children.[58] However, the effect of egg intervention may not persist for longer period.[59] Therefore, intervention programs should consider egg intervention for a longer period with emphasis on overall diet quality and improvement of environmental conditions.[citation needed]

Pregnant and lactating mothers edit

Ensuring proper nutrition of pregnant and lactating mothers is essential.[7] Achieving so by helping women of reproductive age be in good nutritional status at conception is an excellent preventive measure.[7] A focus on the pre-conception period has recently been introduced as a complement to the key phase of the 1000 days of pregnancy and first two years of life.[7] An example of this are attempts to control anemia in women of reproductive age.[7] A well-nourished mother is the first step of stunting prevention, decreasing chances of the baby being born of low birth-weight, which is the first risk factor for future malnutrition.[7]

Balanced protein–energy supplementation in pregnancy seem to improve birth weight of children, with greater effects in undernourished women.[60] Meanwhile, micronutrient supplements and lipid based nutrient supplements (LNS) (providing both macro-and micronutrients) during pregnancy have shown mixed effects on birth weight and -length.[61][62] Similarly, studies supplementing LNS to mothers during pregnancy and lactation and their children during the complementary feeding period show heterogeneous results for stunting.[63][64]

After birth, in terms of interventions for the child, early initiation of breastfeeding, together with exclusive breastfeeding for the first 6 months, are pillars of stunting prevention.[7] Introducing proper complementary feeding after 6 months of age together with breastfeeding until age 2 is the next step.[7]

Policy interventions edit

In summary, key policy interventions for the prevention of stunting are:

  • Improvement in nutrition surveillance activities to identify rates and trends of stunting and other forms of malnutrition within countries.[7] This should be done with an equity perspective, as it is likely that stunting rates will vary greatly between different population groups. The most vulnerable should be prioritized. The same should be done for risk factors such as anemia, maternal under-nutrition, food insecurity, low birth-weight, breastfeeding practices etc. By collecting more detailed information, it is easier to ensure that policy interventions really address the root causes of stunting.
  • Political will to develop and implement national targets and strategies in line with evidence-based international guidelines as well as contextual factors.[7]
  • Designing and implementing policies promoting nutritional and health well-being of mothers and women of reproductive age.[7] The main focus should be on the 1000 days of pregnancy and first two years of life, but the pre-conception period should not be neglected as it can play a significant role in ensuring the fetus and baby's nutrition.
  • Designing and implementing policies promoting proper breastfeeding and complementary feeding practice[7] (focusing on diet diversity for both macro and micronutrients). This can ensure optimal infant nutrition as well as protection from infections that can weaken the child's body. Labor policy ensuring mothers have the chance to breastfeed should be considered where necessary.
  • Introducing interventions addressing social and other health determinants of stunting, such as poor sanitation and access to drinking water, early marriages, intestinal parasite infections, malaria and other childhood preventable disease[7] (referred to as “nutrition-sensitive interventions”), as well as the country's food security landscape. Interventions to keep adolescent girls in school can be effective at delaying marriage with subsequent nutritional benefits for both women and babies.[7] Regulating milk substitutes is also very important to ensure that as many mothers as possible breastfeed their babies, unless a clear contraindication is present.[7]
  • Broadly speaking, effective policies to reduce stunting require multisectoral approaches, strong political commitment, community involvement and integrated service delivery.[7]

Epidemiology edit

According to the World Health organisation if less than 20% of the population is affected by stunting, this is regarded as  "low prevalence" in terms of public health significance.[2] Values of 40% or more are regarded as very high prevalence, and values in between as medium to high prevalence.[2]

UNICEF has estimated that: "Globally, more than one quarter (26 per cent) of children under 5 years of age were stunted in 2011 – roughly 165 million children worldwide."[65] and "In sub-Saharan Africa, 40 per cent of children under 5 years of age are stunted; in South Asia, 39 per cent are stunted."[65] The four countries with the highest prevalence are Timor-Leste, Burundi, Niger and Madagascar where more than half of children under 5 years old are stunted.[65]

The 2020 edition of FAO's Near East and North Africa − Regional Overview of Food Security and Nutrition found that in 2019 22.5 percent of children under the age of five were stunted, 9.2 percent were wasted, and 9.9 percent were overweight across several Arab and North African countries.[66][67]

Trends edit

As of 2015, it was estimated that there were 156 million stunted children under 5 in the world, 90% of them living in low and low-middle income countries.[68] 56% of these were in Asia, and 37% in Africa.[68] It is possible that some of these children concurrently had other forms of malnutrition, including wasting and stunting, and overweight and stunting. No statistics are currently available for these combined conditions. Stunting has been on the decline for the past 15 years, but this decline has been too slow. As a comparison, there were 255 million stunted children in 1990, 224 in 1995, 198 in 2000, 182 in 2005, 169 in 2010, and 156 in 2016.[68] The decline is happening, but it is uneven geographically, it is unequal among different groups in society, and prevalence of stunting remains at unacceptably high numbers.[68] Too many children who are not able to fulfill their genetic physical and cognitive developmental potential. A research paper published in January 2020, which mapped stunting, wasting and underweight in children in low- and middle-income countries, predicted that only five countries would meet global targets for reducing malnutrition by 2025 in all second administrative subdivisions.[4]

Over the period 2000–2015, Asia reduced its stunting prevalence from 38 to 24%, Africa from 38 to 32%, and Latin America and the Caribbean from 18 to 11%.[68] This equates to a relative reduction of 36, 17 and 39% respectively, indicating that Asia and Latin America and the Caribbean have displayed much larger improvements than Africa, which needs to address this issue with much more effort if it is to win the battle against a problem that has been crippling its development for decades. Of these regions, Latin America and the Caribbean are on track to achieve global targets set with global initiatives such as the United Nations Millennium Development Goals and the World Health Assembly targets (see following section on global targets).[68]

Sub-regional stunting rates are as follows: In Africa, the highest rates are observed in East Africa (37.5%).[68] All other Sub-Saharan sub-regions also have high rates, with 32.1% in West Africa, 31.2% in Central Africa, and 28.4% in Southern Africa.[68] North Africa is at 18%, and the Middle East at 16.2%.[68] In Asia, the highest rate is observed in South Asia at 34.4%.[68] South-East Asia is at 26.3%. Pacific Islands also display a high rate at 38.2%. Central and South America are respectively at 15.6 and 9.9%.[68] South Asia, given its very high population at over 1 billion and high prevalence rate of stunting, is the region currently hosting the highest absolute number of children with stunting[68] (60 million plus).

Looking at absolute numbers of children under 5 affected by stunting, it is obvious why current efforts and reductions are insufficient. The absolute number of stunted children has increased in Africa from 50.4 to 58.5 million in the time 2000–2015.[68] This is despite the reduction in percentage prevalence of stunting, and is due to the high rates of population growth. The data therefore indicate that the rate of reduction of stunting in Africa has not been able to counterbalance the increased number of growing children that fall into the trap of malnutrition, due to population growth in the region. This is also true in Oceania, unlike Asia and Latin America and the Caribbean where substantial absolute reductions in the number of stunted children have been observed[68] (for example, Asia reduced its number of stunted children from 133 million to 88 million between 2000 and 2015).

The reduction in stunting is closely linked to poverty reduction and the will and ability of governments to set up solid multisectoral approaches to reduce chronic malnutrition. Low income countries are the only group with more stunted children today than in the year 2000.[68] Conversely, all other countries (high-income, upper-middle income, lower-middle income) have achieved reductions in the numbers of stunted children.[68] This sadly perpetuates a vicious cycle of poverty and malnutrition, whereby malnourished children are not able to maximally contribute to economic development as adults, and poverty increases chances of malnutrition.

Research edit

The Water and Sanitation Program of the World Bank has investigated links between lack of sanitation and stunting in Vietnam and Lao PDR.[69] An example is in Vietnam where the lack of sanitation in rural villages in mountainous regions of Vietnam led to five-year-old children being 3.7 cm shorter than healthy children living in villages with good access to sanitation.[69] This difference in height is irreversible and matters a great deal for a child's cognitive development and future productive potential.[citation needed]

Review articles edit

The Lancet has published two comprehensive series on maternal and child nutrition, in 2008[9] and 2013.[8] The series review the epidemiology of global malnutrition and analyze the state of the evidence for cost-effective interventions that should be scaled-up to achieve impact and global targets. In the first of such series,[9] investigators define the importance of the 1000 day and identify child malnutrition as being responsible for one third of all child deaths worldwide. This finding is key in that it points at malnutrition as a key determinant of child mortality that is often overlooked. When a child dies of pneumonia, malaria or diarrhea (some of the causes of child mortality in the world), it may well be that malnutrition is a key contributing factor that prevents the body from successfully fighting the infection and recovering from these diseases.[9]

In the follow-up series in 2013,[8] the focus on undernutrition is expanded to the increasing burden of obesity in both high, middle and low income countries. Several countries with high levels of child stunting and undernutrition are starting to display worrisome increasing trends of child obesity concurrently, due to increased wealth and the persistence of significant inequalities.[8] The challenges these countries face are particularly difficult as they require intervening on two levels on what has come to be called “double burden of malnutrition”.[8] As an example, in India 30% of children under 5 years of age are stunted, and 20% are overweight. Neglecting these nutritional problems is not an option anymore if countries are to escape poverty traps and provide opportunities to their people to live fulfilling productive lives without stunting.[8]

Nutritional interventions such as dietary supplementation and nutritional education have the potential to decrease stunting.[70]

Examples edit

The 2012 World Health Assembly, with its 194 member states, convened to discuss global issues of maternal, infant and young child nutrition, and developed a plan with 6 targets for 2025.[7] The first of such targets aims to reduce by 40% the number of children who are stunted in the world, by 2025. This would correspond to 100 million stunted children in 2025. At the current reduction rate, the predicted number in 2025 will be 127 million, indicating the need to scale-up and intensify efforts if the global community is to reach its goals.[7]

The World Bank estimates that the extra cost to achieve the reduction goal will be $8.50 yearly per stunted child, for a total of $49.6 Billion for the next decade.[71] Stunting has been shown to be one of the most cost-effective global health problems to invest in, with an estimated return on investment of $18 for every dollar spent thanks to its impact on economic productivity.[71] Despite the evidence in favor of investing in the reduction of stunting, current investments are too low at about $2.9 billion per year, with $1.6 billion coming from Governments, $0.2 billion from donors, and $1.1 paid by individuals.[71]

Sustainable Development Goals edit

In 2015, the United Nations and its member states agreed on a new sustainable development agenda to promote prosperity and reduce poverty, putting forward 17 Sustainable Development Goals (SDGs) to be achieved by 2030.[72] SDG 2 aims to “End hunger, achieve food security and improved nutrition, and promote sustainable agriculture”. Sub-goal 2.2. aims to “by 2030 end all forms of malnutrition, including achieving by 2025 the internationally agreed targets on stunting and wasting in children under five years of age, and address the nutritional needs of adolescent girls, pregnant and lactating women, and older persons”.

The global community has recognized more and more the critical importance of stunting during the past decade. Investments to address it have increased but remain far from being sufficient to solve it and unleash the human potential that remains trapped in malnutrition.

The "Scaling Up Nutrition Movement (SUN)" movement is the main network of governments, non-governmental and international organizations, donors, private companies and academic institutions working together in pursuit of improved global nutrition and a world without hunger and malnutrition.[73] It was launched at the UN General Assembly of 2010 and it calls for country-led multi-sectoral strategies to address child malnutrition by scaling-up evidence-based interventions in both nutrition specific and sensitive areas. As of 2016, 50 countries have joined the SUN Movement with strategies that are aligned with international frameworks of action.[73]

Brazil edit

Brazil displayed a remarkable reduction in the rates of child stunting under age 5, from 37% in 1974, to 7.1% in 2007.[7] This happened in association with impressive social and economic development that reduced the numbers of Brazilians living in extreme poverty (less than $1.25 per day) from 25.6% in 1990 to 4.8% in 2008.[7] The successful reduction in child malnutrition in Brazil can be attributed to strong political commitment that led to improvements in the water and sanitation system, increased female schooling, scale-up of quality maternal and child health services, increased economic power at family level (including successful cash transfer programs), and improvements in food security throughout the country.[7]

Bangladesh edit

Nearly one-third of the children under five years of age are stunted in Bangladesh and 9% are severely stunted.[74] The country is on track in reducing the prevalence of stunted growth. If the current trend continues, the prevalence would be 21% in 2025, while the target is 27%.[75] Maternal undernutrition and increased pathogen load in the intestine are the major risk factors of stunting in Bangladeshi children.[76] Daily supplementation with egg, cow milk, and micronutrient powder found to be effective in improving linear growth of children in a community-based trial in Bangladesh.[57]

Peru edit

After a decade (1995–2005) in which stunting rates stagnated in the country, Peru designed and implemented a national strategy against child malnutrition called crecer ("grow"), which complemented a social development conditional cash-transfer program called juntos, which included a nutritional component.[7] The strategy was multisectoral in that it involved the health, education, water, sanitation and hygiene, agriculture and housing sectors and stakeholders.[7] It was led by the Government and the Prime Minister himself, and included non-governmental partners at both central, regional and community level. After the strategy was implemented, stunting went from 22.9% to 17.9% (2005–2010), with very significant improvements in rural areas where it had been more difficult to reduce stunting rates in the past.[7]

India (Maharashtra) edit

The State of Maharashtra in Central-Western India has been able to produce an impressive reduction in stunting rates in children under 2 years of age from 44% to 22.8% in the 2005–2012 period.[7] This is particularly remarkable given the immense challenges India has faced to address malnutrition, and that the country hosts almost half of all stunted children under 5 in the world.[7][38] This was achieved through integrated community-based programs that were designed by a central advisory body that promoted multisectoral collaboration, provided advice to policy-makers on evidence-based solutions, and advocated for the key role of the 1000 days (pregnancy and first two years of life).[7]

Nepal edit

In Nepal, short maternal stature,[77] low maternal education,[78][79] poor access to health services[79] and poverty[77][78] are strong determinants for stunting. However, in Nepal, stunting has decreased from 57% in 2001 to 36% in 2016, with lower prevalence in urban than in rural settings.[80]

For stunting of growth in plants see Plant nutrition For causes other than malnutrition see Short stature Stunted growth also known as stunting or linear growth failure is defined as impaired growth and development manifested by low height for age 1 It is a primary manifestation of malnutrition or more precisely chronic undernutrition and recurrent infections such as diarrhea and helminthiasis in early childhood and even before birth due to malnutrition during fetal development brought on by a malnourished mother The definition of stunting according to the World Health Organization WHO is for the height for age value to be less than two standard deviations of the median of WHO Child Growth Standards 2 Stunted growth is usually associated with poverty unsanitary environmental conditions

3 More than 85 of the world s stunted children live in Africa and Asia 4 Once established stunting and its effects typically become permanent Stunted children may never regain the height lost as a result of stunting and most children will never gain the corresponding body weight Living in an environment where many people defecate in the open due to lack of sanitation is an important cause of

performance and later on reduced productivity in the work force 2 Reduced cognitive capacity Future risk of obesity 6 Women of shorter stature have a greater risk for complications during child birth due to their smaller pelvis and are at risk of delivering a baby with low birth weight 2 Stunted growth can be passed to the next generation known as the intergenerational cycle of malnutrition 2 The impact of stunting on child development has been established in multiple studies 7 If a child is stunted at age 2 they will have higher risk of poor cognitive and educational achievement in life with subsequent socio economic and inter generational consequences 8 7 Multi country studies have also suggested that stunting is associated with reductions in schooling decreased economic productivity and poverty 9 Stunted children also display higher risk of developing chronic non communicable conditions such as diabetes and obesity as adults 8 9 If a stunted child undergoes substantial weight gain after age 2 there is a higher chance of becoming obese This is believed to be caused by metabolic changes produced by chronic malnutrition that can produce metabolic imbalances if the individual is exposed to excessive or poor quality diets as an adult 8 9 This can lead to higher risk of developing other related non communicable diseases such as hypertension coronary heart disease metabolic syndrome and stroke 8 9 At societal level stunted individuals do not fulfill their physical and cognitive developmental potential and will not be able to contribute maximally to society Stunting can therefore limit economic development and productivity and it has been estimated that it can affect a country s GDP up to 3 8 7 9 Stunting is highly prevalent in low and middle income countries LMICs and has severe consequences including increased risk of infections 10 mortality 11 12 and loss of human capital 10 13 The global prevalence of stunting decreased from 33 to 23 between 2000 and 2016 14 Meanwhile 37 of children in South Asia are stunted and due to a large population size the region bears about 40 of the global burden of stunting 15 Causes edit nbsp The prevalence of child stunting generally increases as cities become smaller and moving away from urban centres while child wasting and overweight are lower and exhibit less evident trends across the rural urbann continuum nbsp

growthFurther information Undernutrition in children In many publications the causes for stunting are considered very similar if not the same as the causes for malnutrition in children However this is not uncontradicted Recent evidence stresses that stunting may not be taken as a synonym of malnutrition 16 but as the natural condition of human height in non Westernized societies 17 Almost all stunting occurs within the 1 000 day period that spans from conception to a child s second birthday 18 19 which constitutes a window of opportunity for growth promotion 20 The recognition of pre natal factors underlines the inter generational aspects of growth 21 and the need for early interventions The three main causes of stunting in South Asia and probably in most developing countries are poor feeding practices poor maternal nutrition and poor sanitation A recent risk assessment analysis for 137 developing countries found that the leading risk factors for stunting were fetal growth restriction birth weight lt 10th centile followed by unimproved sanitation and diarrhea It was estimated that 22 of stunting cases were attributable to environmental factors while 14 were attributable to child nutrition 22 In addition looking at trends from 1970 to 2012 for 116 countries women s education gender equality and finally quantity and quality of foods available at the country level have been instrumental in reducing stunting rates while income growth and governance have played facilitating roles 23 Feeding practices edit Inadequate complementary child feeding and a general lack of vital nutrients beside pure caloric intake is one cause for stunted growth Children need to be fed diets which meet the minimum requirements in terms of frequency and diversity in order to prevent undernutrition 24 Exclusive breastfeeding is recommended for the first six months of life and complementary feeding of nutritious food alongside breastfeeding for children aged six months to 2 years old Prolonged exclusive breastfeeding is associated with undernutrition because breast milk alone is nutritionally insufficient for children over six months old 25 26 Breastfeeding in long time with inadequate complementary feeding leads to growth failure due to insufficient nutrients which are essential for childhood development The relationship between undernutrition and prolonged duration of breastfeeding is mostly observed among children from poor households and whose parents are uneducated as they are more likely to continue breast feeding without meeting minimum dietary diversity requirement 27 Maternal nutrition edit Poor maternal nutrition during pregnancy and breastfeeding can lead to stunted growth of their children Proper nutrition for mothers during the prenatal and postnatal period is important for ensuring healthy birth weight and for healthy childhood growth Prenatal causes of child stunting are associated with maternal undernutrition Low maternal BMI predisposes the fetus to poor growth leading to intrauterine growth retardation which is strongly associated with low birth weight and size 28 Women who are underweight or anemic during pregnancy are more likely to have stunted children which perpetuates the inter generational transmission of stunting Children born with low birthweight are more at risk of stunting 24 However the effect of prenatal undernutrition can be addressed during the postnatal period through proper child feeding practices 28 Maternal undernutrition increases the risk of stunting at 2 years age 18 Based on data from 19 birth cohorts from LMICs 20 of stunting is attributed to being born small for gestational age SGA 29 Further estimated stunting at 2 years attributed to fetal growth restriction and preterm birth in 2011 was 33 in all developing countries and 41 in South Asia 22 Restricted pre and postnatal growth are in turn important determinants of short adult height 30 increasing the likelihood of the next generation also being stunted 31 Sanitation edit There is most likely a link between children s linear growth and household sanitation practices The ingestion of high quantities of fecal bacteria by young children through putting soiled fingers or household items in the mouth leads to intestinal infections This affect children s nutritional status by diminishing appetite reducing nutrient absorption and increasing nutrient losses The diseases recurrent diarrhea and intestinal worm infections helminthiasis which are both linked to poor sanitation have been shown to contribute to child stunting citation needed Research on a global level has found that the proportion of stunting that could be attributed to five or more episodes of diarrhoea before two years of age was 25 32 Since diarrhoea is closely linked with water sanitation and hygiene WASH this is a good indicator for the connection between WASH and stunted growth To what extent improvements in drinking water safety toilet use and good handwashing practices contribute to reduce stunting depends on the how bad these practices were prior to interventions Environmental enteropathy edit The condition termed environmental enteropathy is proposed as an immediate causal factor of childhood stunting 33 34 This is an asymptomatic small intestinal disorder characterized by chronic gut inflammation reduced absorptive surface area and disruption of intestinal barrier function 35 36 This small bowel disorder is attributable to sustained exposure to intestinal pathogens caused by faecal contamination of food and water 37 38 34 Recent evidence confirmed a causal relationship between stunted growth and environmental enteropathy in children 39 Several studies are also underway to examine the link between this condition and stunted growth 37 40 41 The exact pathogenesis of environmental enteropathy causing linear growth failure is unclear but it is hypothesized that chronic inflammatory state and impaired absorption associated with this condition may inhibit bone growth and affect the linear growth during early years of life 42 Diagnosis editGrowth stunting is identified by comparing measurements of children s heights to the World Health Organization 2006 growth reference population children who fall below the fifth percentile of the reference population in height for age are defined as stunted regardless of the reason The lower than fifth percentile corresponds to less than two standard deviations of the WHO Child Growth Standards median citation needed As an indicator of nutritional status comparisons of children s measurements with growth reference curves may be used differently for populations of children than for individual children The fact that an individual child falls below the fifth percentile for height for age on a growth reference curve may reflect normal variation in growth within a population the individual child may be short simply because both parents carried genes for shortness and not because of inadequate nutrition However if substantially more than 5 of an identified child population have height for age that is less than the fifth percentile on the reference curve then the population is said to have a higher than expected prevalence of stunting and malnutrition is generally the first cause considered citation needed Prevention editThree main things are needed to reduce stunting 43 a kind of environment where political commitment can thrive also called an enabling environment applying several nutritional modifications or changes in a population on a large scale which have a high benefit and a low cost a strong foundation that can drive change food security and a supportive health environment through increasing access to safe water and sanitation To prevent stunting it is not just a matter of providing better nutrition but also access to clean water improved sanitation hygienic toilets and hand washing at critical times summarised as WASH Without provision of toilets prevention of tropical intestinal diseases which may affect almost all children in the developing world and lead to stunting will not be possible 44 Studies have looked at ranking the underlying determinants in terms of their potency in reducing child stunting and found in the order of potency 23 percent of dietary energy from non staples greatest impact access to sanitation and women s education access to safe water per capita dietary energy supplyThree of these determinants should receive attention in particular access to sanitation and diversity of calorie sources from food supplies A study by the Institute of Development Studies has stressed that The first two should be prioritized because they have strong impacts yet are farthest below their desired levels 23 The goal of UN agencies governments and NGO is now to optimise nutrition during the first 1000 days of a child s life from pregnancy to the child s second birthday in order to reduce the prevalence of stunting 45 The first 1000 days in a child s life are a crucial window of opportunity because the brain develops rapidly laying the foundation for future cognitive and social ability 46 Furthermore it is also the time when young children are the most at risk of infections that lead to diarrhoea It is the time when they stop breast feeding weaning process begin to crawl put things in their mouths and become exposed to faecal matter from open defecation and environmental enteropathies 45 Dietary interventions to improve stunting edit Previous interventions to reduce stunting have shown modest effects Multiple micronutrient supplementation shows only small benefits for linear growth 47 and results from studies supplementing lipid based nutrient supplements LNS to children are inconclusive 48 49 Educational interventions to improve complementary feeding may achieve behavioral change but have no or small effects on growth 50 51 Further studies on the effect of micronutrient fortification increased availability of key nutrients or increased energy density of complementary foods on stunting also show heterogenous results 52 It is estimated that education interventions if optimally designed and implemented could reduce stunting by 0 6 z scores while food based interventions could reduce stunting by 0 5 z scores 52 which is moderate compared to the average global growth deficit 53 Finally the Lancet series on maternal and child nutrition estimated that the impact of all existing interventions designed to improve nutrition and prevent related diseases in mothers and children could reduce stunting at 3 years by merely 36 54 Hence factors explaining the shortfall in observed associations between child feeding practices and nutrient intake and linear growth have increasingly been the focus of scientific interest 55 Recent works showed promise that intervention with egg may improve linear growth in children 56 57 Comprehensive intervention package containing eggs also found to be effective in improving linear growth in children 58 However the effect of egg intervention may not persist for longer period 59 Therefore intervention programs should consider egg intervention for a longer period with emphasis on overall diet quality and improvement of environmental conditions citation needed Pregnant and lactating mothers edit Ensuring proper nutrition of pregnant and lactating mothers is essential 7 Achieving so by helping women of reproductive age be in good nutritional status at conception is an excellent preventive measure 7 A focus on the pre conception period has recently been introduced as a complement to the key phase of the 1000 days of pregnancy and first two years of life 7 An example of this are attempts to control anemia in women of reproductive age 7 A well nourished mother is the first step of stunting prevention decreasing chances of the baby being born of low birth weight which is the first risk factor for future malnutrition 7 Balanced protein energy supplementation in pregnancy seem to improve birth weight of children with greater effects in undernourished women 60 Meanwhile micronutrient supplements and lipid based nutrient supplements LNS providing both macro and micronutrients during pregnancy have shown mixed effects on birth weight and length 61 62 Similarly studies supplementing LNS to mothers during pregnancy and lactation and their children during the complementary feeding period show heterogeneous results for stunting 63 64 After birth in terms of interventions for the child early initiation of breastfeeding together with exclusive breastfeeding for the first 6 months are pillars of stunting prevention 7 Introducing proper complementary feeding after 6 months of age together with breastfeeding until age 2 is the next step 7 Policy interventions edit In summary key policy interventions for the prevention of stunting are Improvement in nutrition surveillance activities to identify rates and trends of stunting and other forms of malnutrition within countries 7 This should be done with an equity perspective as it is likely that stunting rates will vary greatly between different population groups The most vulnerable should be prioritized The same should be done for risk factors such as anemia maternal under nutrition food insecurity low birth weight breastfeeding practices etc By collecting more detailed information it is easier to ensure that policy interventions really address the root causes of stunting Political will to develop and implement national targets and strategies in line with evidence based international guidelines as well as contextual factors 7 Designing and implementing policies promoting nutritional and health well being of mothers and women of reproductive age 7 The main focus should be on the 1000 days of pregnancy and first two years of life but the pre conception period should not be neglected as it can play a significant role in ensuring the fetus and baby s nutrition Designing and implementing policies promoting proper breastfeeding and complementary feeding practice 7 focusing on diet diversity for both macro and micronutrients This can ensure optimal infant nutrition as well as protection from infections that can weaken the child s body Labor policy ensuring mothers have the chance to breastfeed should be considered where necessary Introducing interventions addressing social and other health determinants of stunting such as poor sanitation and access to drinking water early marriages intestinal parasite infections malaria and other childhood preventable disease 7 referred to as nutrition sensitive interventions as well as the country s food security landscape Interventions to keep adolescent girls in school can be effective at delaying marriage with subsequent nutritional benefits for both women and babies 7 Regulating milk substitutes is also very important to ensure that as many mothers as possible breastfeed their babies unless a clear contraindication is present 7 Broadly speaking effective policies to reduce stunting require multisectoral approaches strong political commitment community involvement and integrated service delivery 7 Epidemiology editAccording to the World Health organisation if less than 20 of the population is affected by stunting this is regarded as low prevalence in terms of public health significance 2 Values of 40 or more are regarded as very high prevalence and values in between as medium to high prevalence 2 UNICEF has estimated that Globally more than one quarter 26 per cent of children under 5 years of age were stunted in 2011 roughly 165 million children worldwide 65 and In sub Saharan Africa 40 per cent of children under 5 years of age are stunted in South Asia 39 per cent are stunted 65 The four countries with the highest prevalence are Timor Leste Burundi Niger and Madagascar where more than half of children under 5 years old are stunted 65 The 2020 edition of FAO s Near East and North Africa Regional Overview of Food Security and Nutrition found that in 2019 22 5 percent of children under the age of five were stunted 9 2 percent were wasted and 9 9 percent were overweight across several Arab and North African countries 66 67 Trends edit As of 2015 it was estimated that there were 156 million stunted children under 5 in the world 90 of them living in low and low middle income countries 68 56 of these were in Asia and 37 in Africa 68 It is possible that some of these children concurrently had other forms of malnutrition including wasting and stunting and overweight and stunting No statistics are currently available for these combined conditions Stunting has been on the decline for the past 15 years but this decline has been too slow As a comparison there were 255 million stunted children in 1990 224 in 1995 198 in 2000 182 in 2005 169 in 2010 and 156 in 2016 68 The decline is happening but it is uneven geographically it is unequal among different groups in society and prevalence of stunting remains at unacceptably high numbers 68 Too many children who are not able to fulfill their genetic physical and cognitive developmental potential A research paper published in January 2020 which mapped stunting wasting and underweight in children in low and middle income countries predicted that only five countries would meet global targets for reducing malnutrition by 2025 in all second administrative subdivisions 4 Over the period 2000 2015 Asia reduced its stunting prevalence from 38 to 24 Africa from 38 to 32 and Latin America and the Caribbean from 18 to 11 68 This equates to a relative reduction of 36 17 and 39 respectively indicating that Asia and Latin America and the Caribbean have displayed much larger improvements than Africa which needs to address this issue with much more effort if it is to win the battle against a problem that has been crippling its development for decades Of these regions Latin America and the Caribbean are on track to achieve global targets set with global initiatives such as the United Nations Millennium Development Goals and the World Health Assembly targets see following section on global targets 68 Sub regional stunting rates are as follows In Africa the highest rates are observed in East Africa 37 5 68 All other Sub Saharan sub regions also have high rates with 32 1 in West Africa 31 2 in Central Africa and 28 4 in Southern Africa 68 North Africa is at 18 and the Middle East at 16 2 68 In Asia the highest rate is observed in South Asia at 34 4 68 South East Asia is at 26 3 Pacific Islands also display a high rate at 38 2 Central and South America are respectively at 15 6 and 9 9 68 South Asia given its very high population at over 1 billion and high prevalence rate of stunting is the region currently hosting the highest absolute number of children with stunting 68 60 million plus Looking at absolute numbers of children under 5 affected by stunting it is obvious why current efforts and reductions are insufficient The absolute number of stunted children has increased in Africa from 50 4 to 58 5 million in the time 2000 2015 68 This is despite the reduction in percentage prevalence of stunting and is due to the high rates of population growth The data therefore indicate that the rate of reduction of stunting in Africa has not been able to counterbalance the increased number of growing children that fall into the trap of malnutrition due to population growth in the region This is also true in Oceania unlike Asia and Latin America and the Caribbean where substantial absolute reductions in the number of stunted children have been observed 68 for example Asia reduced its number of stunted children from 133 million to 88 million between 2000 and 2015 The reduction in stunting is closely linked to poverty reduction and the will and ability of governments to set up solid multisectoral approaches to reduce chronic malnutrition Low income countries are the only group with more stunted children today than in the year 2000 68 Conversely all other countries high income upper middle income lower middle income have achieved reductions in the numbers of stunted children 68 This sadly perpetuates a vicious cycle of poverty and malnutrition whereby malnourished children are not able to maximally contribute to economic development as adults and poverty increases chances of malnutrition Research editThe Water and Sanitation Program of the World Bank has investigated links between lack of sanitation and stunting in Vietnam and Lao PDR 69 An example is in Vietnam where the lack of sanitation in rural villages in mountainous regions of Vietnam led to five year old children being 3 7 cm shorter than healthy children living in villages with good access to sanitation 69 This difference in height is irreversible and matters a great deal for a child s cognitive development and future productive potential citation needed Review articles edit The Lancet has published two comprehensive series on maternal and child nutrition in 2008 9 and 2013 8 The series review the epidemiology of global malnutrition and analyze the state of the evidence for cost effective interventions that should be scaled up to achieve impact and global targets In the first of such series 9 investigators define the importance of the 1000 day and identify child malnutrition as being responsible for one third of all child deaths worldwide This finding is key in that it points at malnutrition as a key determinant of child mortality that is often overlooked When a child dies of pneumonia malaria or diarrhea some of the causes of child mortality in the world it may well be that malnutrition is a key contributing factor that prevents the body from successfully fighting the infection and recovering from these diseases 9 In the follow up series in 2013 8 the focus on undernutrition is expanded to the increasing burden of obesity in both high middle and low income countries Several countries with high levels of child stunting and undernutrition are starting to display worrisome increasing trends of child obesity concurrently due to increased wealth and the persistence of significant inequalities 8 The challenges these countries face are particularly difficult as they require intervening on two levels on what has come to be called double burden of malnutrition 8 As an example in India 30 of children under 5 years of age are stunted and 20 are overweight Neglecting these nutritional problems is not an option anymore if countries are to escape poverty traps and provide opportunities to their people to live fulfilling productive lives without stunting 8 Nutritional interventions such as dietary supplementation and nutritional education have the potential to decrease stunting 70 Examples editThe 2012 World Health Assembly with its 194 member states convened to discuss global issues of maternal infant and young child nutrition and developed a plan with 6 targets for 2025 7 The first of such targets aims to reduce by 40 the number of children who are stunted in the world by 2025 This would correspond to 100 million stunted children in 2025 At the current reduction rate the predicted number in 2025 will be 127 million indicating the need to scale up and intensify efforts if the global community is to reach its goals 7 The World Bank estimates that the extra cost to achieve the reduction goal will be 8 50 yearly per stunted child for a total of 49 6 Billion for the next decade 71 Stunting has been shown to be one of the most cost effective global health problems to invest in with an estimated return on investment of 18 for every dollar spent thanks to its impact on economic productivity 71 Despite the evidence in favor of investing in the reduction of stunting current investments are too low at about 2 9 billion per year with 1 6 billion coming from Governments 0 2 billion from donors and 1 1 paid by individuals 71 Sustainable Development Goals edit In 2015 the United Nations and its member states agreed on a new sustainable development agenda to promote prosperity and reduce poverty putting forward 17 Sustainable Development Goals SDGs to be achieved by 2030 72 SDG 2 aims to End hunger achieve food security and improved nutrition and promote sustainable agriculture Sub goal 2 2 aims to by 2030 end all forms of malnutrition including achieving by 2025 the internationally agreed targets on stunting and wasting in children under five years of age and address the nutritional needs of adolescent girls pregnant and lactating women and older persons The global community has recognized more and more the critical importance of stunting during the past decade Investments to address it have increased but remain far from being sufficient to solve it and unleash the human potential that remains trapped in malnutrition The Scaling Up Nutrition Movement SUN movement is the main network of governments non governmental and international organizations donors private companies and academic institutions working together in pursuit of improved global nutrition and a world without hunger and malnutrition 73 It was launched at the UN General Assembly of 2010 and it calls for country led multi sectoral strategies to address child malnutrition by scaling up evidence based interventions in both nutrition specific and sensitive areas As of 2016 50 countries have joined the SUN Movement with strategies that are aligned with international frameworks of action 73 Brazil edit Brazil displayed a remarkable reduction in the rates of child stunting under age 5 from 37 in 1974 to 7 1 in 2007 7 This happened in association with impressive social and economic development that reduced the numbers of Brazilians living in extreme poverty less than 1 25 per day from 25 6 in 1990 to 4 8 in 2008 7 The successful reduction in child malnutrition in Brazil can be attributed to strong political commitment that led to improvements in the water and sanitation system increased female schooling scale up of quality maternal and child health services increased economic power at family level including successful cash transfer programs and improvements in food security throughout the country 7 Bangladesh edit Nearly one third of the children under five years of age are stunted in Bangladesh and 9 are severely stunted 74 The country is on track in reducing the prevalence of stunted growth If the current trend continues the prevalence would be 21 in 2025 while the target is 27 75 Maternal undernutrition and increased pathogen load in the intestine are the major risk factors of stunting in Bangladeshi children 76 Daily supplementation with egg cow milk and micronutrient powder found to be effective in improving linear growth of children in a community based trial in Bangladesh 57 Peru edit After a decade 1995 2005 in which stunting rates stagnated in the country Peru designed and implemented a national strategy against child malnutrition called crecer grow which complemented a social development conditional cash transfer program called juntos which included a nutritional component 7 The strategy was multisectoral in that it involved the health education water sanitation and hygiene agriculture and housing sectors and stakeholders 7 It was led by the Government and the Prime Minister himself and included non governmental partners at both central regional and community level After the strategy was implemented stunting went from 22 9 to 17 9 2005 2010 with very significant improvements in rural areas where it had been more difficult to reduce stunting rates in the past 7 India Maharashtra edit The State of Maharashtra in Central Western India has been able to produce an impressive reduction in stunting rates in children under 2 years of age from 44 to 22 8 in the 2005 2012 period 7 This is particularly remarkable given the immense challenges India has faced to address malnutrition and that the country hosts almost half of all stunted children under 5 in the world 7 38 This was achieved through integrated community based programs that were designed by a central advisory body that promoted multisectoral collaboration provided advice to policy makers on evidence based solutions and advocated for the key role of the 1000 days pregnancy and first two years of life 7 Nepal edit In Nepal short maternal stature 77 low maternal education 78 79 poor access to health services 79 and poverty 77 78 are strong determinants for stunting However in Nepal stunting has decreased from 57 in 2001 to 36 in 2016 with lower prevalence in urban than in rural settings 80 See also editCompensatory growth Failure to thrive Food security Global Alliance for Improved Nutrition Undernutrition in
