The latest available data indicate that 38% of South Asia's children aged 0–59 months are stunted. Such high prevalence combined with the region's large child population explain why South Asia bears about 40% of the global burden of stunting. Recent analyses indicate that the poor diets of children in the first years of life, the poor nutrition of women before and during pregnancy and the prevailing poor sanitation practices in households and communities are important drivers of stunting, most likely because of underlying conditions of women's status, food insecurity, poverty, and social inequalities. With this evidence in mind, UNICEF Regional Office for South Asia convened the Regional Conference: Stop Stunting: Improving Child Feeding, Women's Nutrition, and Household Sanitation in South Asia (New Delhi, November 10–12, 2014). The Conference provided a knowledge ‐ for ‐ action platform with three objectives: (1) share state ‐ of ‐ the ‐ art research findings on the causes of child stunting and its consequences for child growth and development and the sustainable growth and development of nations; (2) discuss better practices and the cost and benefits of scaling up programmes to improve child feeding, women's nutrition, and household sanitation in South Asia; and (3) identify implications for sectoral and cross ‐ sectoral policy, programme, advocacy and research to accelerate progress in reducing child stunting in South Asia. This overview paper summarizes the rationale for the focus on improving child feeding, women's nutrition, and household sanitation as priority areas for investment to prevent child stunting in South Asia. It builds on the invited papers presented at or developed as a follow on to the Stop Stunting Conference. [ABSTRACT FROM AUTHOR]

The sustainable development of nations relies on children developing to their full potential and leading healthy, productive, and prosperous lives. Poor nutrition in early life threatens the growth and development of children, especially so in South Asia, which has the highest burdens of stunting, wasting, and anaemia in the world. Targeted actions to reduce stunting and other forms of child malnutrition in South Asia should be informed by an understanding of what drives poor nutrition in children, who is most affected, and effective programme approaches. To this end, the UNICEF Regional Office for South Asia commissioned a series of papers in 2016–2017 to fill knowledge gaps in the current body of evidence on maternal and child nutrition in South Asia, including analyses of: (a) the links between anthropometric failure in children and child development; (b) the time trends, current distribution, disparities and inequities of child stunting, wasting and anaemia, and their direct and underlying causes, including maternal anaemia, low birth weight, breastfeeding, and complementary feeding; (c) policy and programme actions to increase the coverage of nutrition interventions during pregnancy, improve breastfeeding practices, and care for severely wasted children. This overview paper summarizes the evidence from these analyses and examines the implications for the direction of future advocacy, policy, and programme actions to improve maternal and child nutrition in South Asia.

Information on malnutrition for school‐age children and adolescents (5–19 years) in South Asia is fragmented and inconsistent, which limits the prioritization of nutrition policies, programmes and research for this age group. This scoping review aimed to synthesize existing evidence on the burden of malnutrition for children and adolescents aged 5–19 years in South Asia, and on interventions to improve their nutritional status. Cochrane Library, EMBASE, Medline and Google Scholar were systematically searched for articles published between January 2016 and November 2022. Eligible studies reported the prevalence of undernutrition, overweight/obesity, micronutrient deficiencies and unhealthy dietary intakes, and interventions that aimed to address these in South Asia. In total, 296 articles met our inclusion criteria. Evidence revealed widespread, yet heterogeneous, prevalence of undernutrition among South Asian children and adolescents: thinness (1.9%–88.8%), wasting (3%–48%), underweight (9.5%–84.4%) and stunting (3.7%–71.7%). A triple burden of malnutrition was evident: the prevalence of overweight and obesity ranged from 0.2% to 73% and 0% to 38% (with rapidly rising trends), respectively, alongside persistent micronutrient deficiencies. Diets often failed to meet nutritional requirements and high levels of fast‐food consumption were reported. Education, fortification, supplementation and school feeding programmes demonstrated beneficial effects on nutritional status. Comprehensive and regular monitoring of all forms of malnutrition among children and adolescents, across all countries in South Asia is required. Further, more large‐scale intervention research is needed to ensure policy and programmes effectively target and address malnutrition among children and adolescents in South Asia. Key messages: A triple burden of malnutrition (undernutrition, overweight/obesity and micronutrient deficiencies) is affecting children and adolescents (5–19 years) in South Asia, with heterogeneity within, and between, countries.In most countries, nationally representative data on the nutritional status of children and adolescents is absent and should be prioritized.Interventions targeting children and adolescents are primarily limited to small‐scale trials and focused predominantly on undernutrition and micronutrient deficiencies despite rapidly rising rates of overweight and obesity.Further research is needed to inform the scalability and sustainability of nutrition interventions across different contexts and to understand the effectiveness of policies and programmes that address overnutrition.

Progress to improve nutrition among women, infants and children in South Asia has fallen behind the pace needed to meet established global targets. Renewed political commitment and monitoring of nutrition interventions are required to improve coverage and quality of care. Our study aimed to assess the availability of national nutrition policies, programmes, and coverage data of nutrition interventions for women, children, and adolescents in eight countries in South Asia. We reviewed relevant policy and programme documents, examined questionnaires used in the most recent rounds of 20 nationally representative surveys, and generated an evidence gap map on the availability of policies, programmes, and survey data to track progress on coverage of globally recommended nutrition interventions. Current policies and programmes in South Asian countries addressed almost all the recommended nutrition interventions targeted at women, children, and adolescents. There was a strong policy focus in all countries, except Maldives, on health system platforms such as antenatal and postnatal care and child growth and development. Survey data on nutrition intervention coverage was most available in India and Nepal, while Bangladesh and Bhutan had the least. Though countries in South Asia have committed to national nutrition policies and strategies, national surveys had substantial data gaps, precluding progress tracking of nutrition intervention coverage. Greater attention and effort are needed for multisectoral collaboration to promote and strengthen nutrition data systems. Key messages: Most South Asian countries had several policies and programmes in place which considered or addressed nutrition interventions across the life course.Nationally representative surveys provide coverage data for evidence‐based recommendations to improve policy and programme actions.Significant coverage data gaps remain in nationally representative surveys around counselling during pregnancy, interventions targeted for newborns, infant, and young child feeding, and counselling on and identification and treatment of severe and moderate acute malnutrition.Mobilising political commitment and increasing multisectoral collaboration are required for an enabling environment in support of nutrition data systems in South Asia.

Context‐specific research is needed on the relationship between household animal production and nutrition outcomes to inform programmes intervening in small‐scale animal production. We examined associations between household animal/fishpond ownership and animal source food (ASF) consumption among 6‐ to 12‐month‐old infants enroled in the control arm of a cluster‐randomised controlled trial in rural Bangladesh. We measured ASF consumption using a 7‐day food frequency questionnaire at 6, 9 and 12 months and assessed household animal/fishpond ownership at 12 months. We developed negative binomial regression models with random intercepts for infant and cluster, controlling for infant age and sex, maternal age, socioeconomic status and season. Models were stratified by a dichotomised maternal decision‐making score. Compared with infants in households without each animal type, those with 4–10 and ≥11 poultry consumed eggs 1.3 (95% confidence interval [CI]: 1.1, 1.6) and 1.6 (95% CI: 1.3, 2.0) times more, respectively; 2–3 and ≥4 dairy‐producing animals consumed dairy 1.9 (95% CI: 1.3, 2.7) and 2.0 (95% CI: 1.3, 3.1) times more, respectively; and ≥12 meat‐producing animals consumed meat 1.4 (95% CI: 1.0, 1.8) times more. It was unclear whether there was an association between fishpond ownership and fish consumption. Our results did not suggest that maternal decision‐making power was a modifier in the relationship between animal/fishpond ownership and ASF consumption. In this South Asian context, strategies intervening in household animal production may increase infant consumption of eggs, dairy and meat, but not necessarily fish. Research is needed on the role of market access and other dimensions of women's empowerment. Key messages: Household ownership of poultry and dairy‐ and meat‐producing animals was associated with higher infant intakes of eggs, dairy and meat, respectively. There was not a clear association between household fishpond ownership and infant fish consumption.While we found no significant differences in these relationships by maternal decision‐making power, future research in this setting should consider the relative importance of other dimensions of women's empowerment or other contextual factors, such as market access.In Bangladesh and similar rural South Asian settings, programmes aiming to impact infant and child diet through agricultural interventions must assess the factors constraining both production and consumption.

South Asia is home to the largest number of stunted children worldwide: 65 million or 37% of all South Asian children under 5 were stunted in 2014. The costs to society as a result of stunting during childhood are high and include increased mortality, increased morbidity (in childhood and later as adults), decreased cognitive ability, poor educational outcomes, lost earnings and losses to national economic productivity. Conversely, investing in nutrition provides many benefits for poverty reduction and economic growth. This article draws from analyses conducted in four sub ‐ Saharan countries to demonstrate that investments in nutrition can also be very cost ‐ effective in South Asian countries. Specifically, the analyses demonstrate that scaling up a set of 10 critical nutrition ‐ specific interventions is highly cost ‐ effective when considered as a package. Most of the interventions are also very cost ‐ effective when considered individually. By modelling cost ‐ effectiveness of different scale ‐ up scenarios, the analysis offers insights into ways in which the impact of investing in nutrition interventions can be maximized under budget constraints. Rigorous estimations of the costs and benefits of nutrition investments, similar to those reported here for sub ‐ Saharan countries, are an important next step for all South Asian countries in order to drive political commitment and action and to enhance allocative efficiency of nutrition resources.

Anemia remains one of the most intractable public health challenges in South Asia. This paper analyzes individual‐level and household‐level determinants of anemia among children and women in Nepal and Pakistan. Applying multivariate modified Poisson models to recent national survey data, we find that the prevalence of anemia was significantly higher among women from the poorest households in Pakistan (adjusted prevalence ratio [95% CI]: 1.10 [1.04–1.17]), women lacking sanitation facilities in Nepal (1.22 [1.12–1.33]), and among undernourished women (BMI < 18.5 kg/m2) in both countries (Nepal: 1.10 [1.00–1.21] and Pakistan: 1.07 [1.02–1.13]). Similarly, children in both countries were more likely to be anemic if stunted (Nepal: 1.19 [1.09–1.30] and Pakistan: 1.10 [1.07–1.14]) and having an anemic mother (Nepal: 1.31 [1.20–1.42] and Pakistan: 1.21 [1.17–1.26]). Policies and programs need to target vulnerable and hard‐to‐reach subpopulations who continue to bear a disproportionate burden of anemia. Covariates of poverty underpin rates of anemia among children and their mothers, but income growth alone will not suffice to resolve such deeply entrenched problems. Greater understanding of the relative role of various diet, health, sanitation, and educational factors by local context should guide investments to resolve anemia in tandem with stunting and maternal underweight.

Women's nutritional status remains poor in South Asia, impacting maternal and infant health outcomes. Women's household status is also low, as evidenced by eating behaviours. We started with triadic qualitative interviews with newly married women, husbands and mothers‐in‐law to explore the link between women's status and eating patterns, followed by longitudinal data from a cohort of 200 newly married women in rural Nepal to measure associations over time. Quantitative data were collected every 6 months for 18 months (four rounds of data) between 2018 and 2020. Interviews suggested that household relationships, women's status, and how much and what types of food she was given were intricately linked. Using mixed effects logistic regression models, we explore the association between markers of changing women's status (becoming pregnant, giving birth and working outside the home) on two outcomes (eating last always/usually and achieving minimum dietary diversity). We also explore for interaction between women's status and household food insecurity. Pregnancy increases women's dietary diversity, but this is not sustained post‐partum. Women who work outside the home are less likely to eat last in the household. Food insecurity is associated with both the order of household eating and dietary diversity. Interactions between food insecurity and giving birth suggested that women who give birth in food insecure households are more likely to eat last in the household. Changes in women's household status are associated with some improvements in dietary diversity and order of household eating, but the associations are not long‐lasting and depend on food security status. Key messages: Newly married women in rural Nepal face low dietary diversity, often eat last, and this does not improve over the first few years of marriage.Although pregnancy does improve dietary diversity, this does not remain post‐partum.Working outside the home does appear to lead women to not eat last as frequently.Food insecurity is the most important factor contributing to dietary diversity and order of household eating.

Maternal anaemia prevalence in low‐income countries is unacceptably high. Our research explored the individual‐, family‐ and community‐level factors affecting antenatal care uptake, iron folic acid (IFA) intake and consumption of micronutrient‐rich diets among pregnant women in the plains of Nepal. We discuss how these findings informed the development of a home visit and community mobilisation intervention to reduce anaemia in pregnancy. We used a qualitative methodology informed by the socio‐ecological framework, conducting semi‐structured interviews with recently pregnant women and key informants, and focus group discussions with mothers‐in‐law and fathers. We found that harmful gender norms restricted women's access to nutrient‐rich food, restricted their mobility and access to antenatal care. These norms also restricted fathers' role to that of the provider, as opposed to the caregiver. Pregnant women, mothers‐in‐law and fathers lacked awareness about iron‐rich foods and how to manage the side effects of IFA. Fathers lacked trust in government health facilities affecting access to care and trust in the efficacy of IFA. Our research informed interventions by (1) informing the development of intervention tools and training; (2) informing the intervention focus to engaging mothers‐in‐law and men to enable behaviour change; and (3) demonstrating the need to work in synergy across individual, family and community levels to address power and positionality, gender norms, trust in health services and harmful norms. Participatory groups and home visits will enable the development and implementation of feasible and acceptable strategies to address family and contextual issues generating knowledge and an enabling environment for behaviour change.

Some 37% (~64 million) South Asian children under 5 years are stunted. Most stunting occurs during the complementary feeding period (6-23 months). Our objective was to (a) characterize complementary feeding practices in South Asia and (b) review the effectiveness of information, education, and counselling (IEC) interventions aiming to improve complementary feeding in South Asia. We conducted a comprehensive review of (a) the latest nationally representative survey data and (b) peer-reviewed interventions (January 1990 to December 2015) that used IEC as the main strategy to improve complementary feeding. The analytical sample included 30,966 children aged 6-23 months. Foods made from grains are the main complementary food (76.8% of children). Only 33.2% of children are fed fruits and vegetables rich in vitamin A and a mere 17.1% are fed complementary foods containing meat, fish, poultry and/or eggs. Timely introduction, minimum meal frequency, minimum dietary diversity, and minimum acceptable diet were estimated at 57.4%, 47.7%, 33.0%, and 20.5%, respectively. The evidence on the effectiveness of IEC interventions is limited in quantity, quality, and scale. The 12 intervention studies that met the inclusion criteria indicate that IEC interventions delivered by many types of primary care workers/community resource persons using multiple contact opportunities improved the timeliness, frequency, diversity, and/or adequacy of complementary feeding. However, acceptability, availability, and affordability seem to constrain improvements in diet diversity, particularly foods of animal origin. The small size of most intervention studies and the training and/or supervision intensity of counsellors raise concerns about the potential for scale and/or sustainability of some of the interventions reviewed.

India's national nutrition and health programmes are largely designed to provide evidence ‐ based nutrition ‐ specific interventions, but intervention coverage is low due to a combination of implementation challenges, capacity and financing gaps. Global cost estimates for nutrition are available but national and subnational costs are not. We estimated national and subnational costs of delivering recommended nutrition ‐ specific interventions using the Scaling Up Nutrition (SUN) costing approach. We compared costs of delivering the SUN interventions at 100% scale with those of nationally recommended interventions. Target populations (TP) for interventions were estimated using national population and nutrition data. Unit costs (UC) were derived from programmatic data. The cost of delivering an intervention at 100% coverage was calculated as (UC*projected TP). Cost estimates varied; estimates for SUN interventions were lower than estimates for nationally recommended interventions because of differences in choice of intervention, target group or unit cost. US$5.9bn/year are required to deliver a set of nationally recommended nutrition interventions at scale in India, while US$4.2bn are required for the SUN interventions. Cash transfers (49%) and food supplements (40%) contribute most to costs of nationally recommended interventions, while food supplements to prevent and treat malnutrition contribute most to the SUN costs. We conclude that although such costing is useful to generate broad estimates, there is an urgent need for further costing studies on the true unit costs of the delivery of nutrition ‐ specific interventions in different local contexts to be able to project accurate national and subnational budgets for nutrition in India.

Global evidence shows that children's growth deteriorates rapidly during/after illness if foods and feeding practices do not meet the additional nutrient requirements associated with illness/convalescence. To inform policies and programmes, we conducted a review of the literature published from 1990 to 2014 to document how children 0–23 months old are fed during/after common childhood illnesses. The review indicates that infant and young child feeding (IYCF) during common childhood illnesses is far from optimal. When sick, most children continue to be breastfed, but few are breastfed more frequently, as recommended. Restriction/withdrawal of complementary foods during illness is frequent because of children's anorexia (perceived/real), poor awareness of caregivers' about the feeding needs of sick children, traditional beliefs/behaviours and/or suboptimal counselling and support by health workers. As a result, many children are fed lower quantities of complementary foods and/or are fed less frequently when they are sick. Mothers/caregivers often turn to family/community elders and traditional/non ‐ qualified practitioners to seek advice on how to feed their sick children. Thus, traditional beliefs and behaviours guide the use of ‘special’ feeding practices, foods and diets for sick children. A significant proportion of mothers/caregivers turn to the primary health care system for support but receive little or no advice. Building the knowledge, skills and capacity of community health workers and primary health care practitioners to provide mothers/caregivers with accurate and timely information, counselling and support on IYCF during and after common childhood illnesses, combined with large ‐ scale communication programmes to address traditional beliefs and norms that may be harmful, is an urgent priority to reduce the high burden of child stunting in South Asia.

Women's disempowerment is hypothesised to contribute to high rates of undernutrition among South Asian children. However, evidence for this relationship has not been systematically reviewed.This review of empirical studies aims to: (1) synthesise the evidence linking women's empowerment and child nutritional status in South Asia and (2) suggest directions for future research.We systematically searched Global Health, Embase (classic and Ovid), MEDLINE, Campbell Collaboration, Popline, Eldis, Web of Science, EconLit and Scopus. We generated 1661 studies for abstract and title screening. We full-text screened 44 of these, plus 10 additional studies the authors were aware of. Only 12 studies fulfilled our inclusion criteria.We included English materials published between 1990 and 2012 that examined the relationship(s) of at least one women's empowerment domain and nutritional status among South Asian children. Data were extracted and synthesised within three domains of empowerment: control of resources and autonomy, workload and time, and social support. The results showed women's empowerment to be generally associated with child anthropometry, but the findings are mixed. Inter-study differences in population characteristics, settings or methods/conceptualisations of women's empowerment, and the specific domains studied, likely contributed to these inconsistencies. This review also highlights that different women's empowerment domains may relate differently to child nutritional status. Future research should aim to harmonise definitions of women's empowerment, which key domains it should include, and how it is measured. Rigorous evaluation work is also needed to establish which policies and programmes facilitate women's empowerment and in turn, foster child nutritional well-being. [ABSTRACT FROM AUTHOR]

The nutritional status of women before pregnancy, during pregnancy, and after delivery has far reaching consequences for maternal health and child survival, growth, and development. In South Asia, the high prevalence of short stature, thinness, and anaemia among women of reproductive age underlie the high prevalence of child undernutrition in the region, whereas overweight and obesity are rising concerns. A systematic review of evidence (2000–2017) was conducted to identify barriers and programme approaches to improving the coverage of maternal nutrition interventions in the region. The search strategy used 13 electronic bibliographic databases and 14 websites of development and technical agencies and identified 2,247 citations. Nine studies conducted in Bangladesh (n = 2), India (n = 5), Nepal (n = 1), and Pakistan (n = 1) were selected for the review, and outcomes included the receipt and consumption of iron and folic acid and calcium supplements and the receipt of information on dietary intake during pregnancy. The studies indicate that a range of barriers acting at the individual (maternal), household, and health service delivery levels affects intervention coverage during pregnancy. Programme approaches that were effective in improving intervention coverage addressed barriers at multiple levels and had several common features: use of formative research and client assessments to inform the design of programme approaches and actions; community‐based delivery platforms to increase access to services; engagement of family members, as well as pregnant women, in influencing behavioural change; actions to improve the capacity, supervision, monitoring, and motivation of front‐line service providers to provide information and counselling; and access to free supplements.

Stunting (length‐for‐age z score < −2) before 2 years of age has shown associations with poor child developmental indicators, but information at the population level is scarce in South Asia, the region with the highest burden of stunting. We examined associations between z scores (i.e., height for age [HAZ], weight for age [WAZ], and weight for height [WHZ]) and undernutrition (i.e., stunting [HAZ < −2], wasting [WHZ < −2], and underweight [WAZ < −2]) with learning/cognition and social–emotional development among children 36–59 months of age. Data from Multiple Indicator Cluster Surveys in Bangladesh (n = 8,659), Bhutan (n = 2,038), Nepal (n = 2,253), and Pakistan (Punjab n = 11,369 and Sindh n = 6,718) were used. Children were considered developmentally "on‐track" in learning/cognition or social–emotional domains if they met specific early child development criteria. Meta‐analysis was conducted to examine regional associations, adjusting for socio‐economic status, early childhood education, and quality of care. In a pooled sample, on‐track learning/cognition development was positively associated with HAZ (OR = 1.17, 95% CI [1.07, 1.27]) and WAZ (OR = 1.18, 95% CI [1.07, 1.31]) and negatively associated with stunting (OR = 0.72, 95% CI [0.60, 0.86]) and underweight (OR = 0.75, 95% CI [0.66, 0.86]) but not associated with WHZ or wasting. On‐track development of social–emotional domain was not associated with any z scores or undernutrition indicators. Across several countries of South Asia, stunted children were less likely to be developmentally "on track" for learning/cognition. It is likely that interventions that prevent stunting may benefit child development, leading to significant individual and societal gains given the large burden of child stunting in regions like South Asia. [ABSTRACT FROM AUTHOR]

Although there has been a focus on preventing stunting over the past decade, wasting has received less policy and programmatic attention. Recent national surveys from six South Asian countries were pooled to generate a dataset of 62,509 children aged 0 to 59 months to explore associations between low birthweight (LBW) and suboptimal infant and young child feeding (IYCF) practices with child wasting, severe wasting, and the co‐occurrence of wasting and stunting. Logistic regression models accounted for the surveys' clustered designs and adjusted for a potential confounding factors. Children with reported LBW had significantly higher odds of being wasted (adjusted odds ratio [95% CI]: 1.60 [1.45, 1.76]) or severely wasted (1.57 [1.34, 1.83]), compared with non‐LBW children. Similarly, children aged 0 to 23 months who were not breastfed within the first hour post‐partum, those who were provided prelacteal feeds, and those aged 0 to 5 months who were not exclusively breastfed, were more likely to be wasted (P < 0.05 for all three feeding practices). In India, not achieving minimum diet diversity and minimum adequate diet were significantly associated with the co‐occurrence of stunting and wasting. In other words, many key domains of concern to development agents who seek to address stunting are also of direct concern to those focused on wasting. The co‐occurrence of wasting and stunting requires more integrated interventions. That is, programmes aimed at preventing LBW and poor IYCF to avert stunting should be linked more effectively with actions aimed at the management of wasting. [ABSTRACT FROM AUTHOR]

Severe wasting is the most widespread form of severe acute malnutrition, affecting an estimated 17 million children globally. This analysis assesses the effectiveness of Pakistan's community management of acute malnutrition (CMAM) programme. We conducted a retrospective case series analysis of 32,458 children aged 6–59 months who were admitted to the programme with a mid‐upper arm circumference (MUAC) < 115 mm (January 1–December 31, 2014). We found that at admission, 59.6% of the children were girls and 87.4% were in the age group 6–23 months old. While in the programme, 120 children (0.4%) died, 3,456 (10.6%) defaulted, and 28,882 (89.0%) were discharged after a mean length of stay of 69.3 ± 25.7 days. Children's mean weight gain while in the programme was 3.2 ± 2.7 g/kg body weight/day. At discharge, 28,499 children (98.7% of discharged) had recovered (MUAC ≥ 125 mm). The odds of death were significantly higher among children with weight‐for‐height (WHZ) < −3 and/or height‐for‐age (HAZ) < −2 at admission. The odds of recovery on the basis of MUAC ≥125 mm were higher among children with HAZ ≥ −2 at admission. The odds of recovery on the basis of WHZ ≥ −2 were significantly higher among children with WHZ ≥ −3 and/or HAZ < −2 at admission. Pakistan's CMAM programme is effective in achieving good survival and recovery rates. Population‐level impact could be increased by giving priority to children 6–23 months old and children with multiple anthropometric failure and by scaling up CMAM in the provinces and areas where the risk, prevalence, and/or burden of severe acute malnutrition is highest.

We analysed socio‐economic inequalities in stunting in South Asia and investigated disparities associated with factors at the individual, caregiver, and household levels (poor dietary diversity, low maternal education, and household poverty). We used time‐series analysis of data from 55,459 children ages 6–23 months from Demographic and Health Surveys in Bangladesh, India, Nepal, and Pakistan (1991–2014). Logistic regression models, adjusted for age, sex, birth order, and place of residency, examined associations between stunting and multiple types of socio‐economic disadvantage. All countries had high stunting rates. Bangladesh and Nepal recorded the largest reductions—2.9 and 4.1 percentage points per year, respectively—compared to 1.3 and 0.6 percentage points in India and Pakistan, respectively. Socio‐economic adversity was associated with increased risk of stunting, regardless of disadvantage type. Poor children with inadequate diets and with poorly educated mothers experienced greater risk of stunting. Although stunting rates declined in the most deprived groups, socio‐economic differences were largely preserved over time and in some cases worsened, namely, between wealth quintiles. The disproportionate burden of stunting experienced by the most disadvantaged children and the worsening inequalities between socio‐economic groups are of concern in countries with substantial stunting burdens. Closing the gap between best and worst performing countries, and between most and least disadvantaged groups within countries, would yield substantial improvements in stunting rates in South Asia. To do so, greater attention needs to be paid to addressing the social, economic, and political drivers of stunting with targeted efforts towards the populations experiencing the greatest disadvantage and child growth faltering.
