Stunting and chronic undernutrition among children in South Asia remain a major unresolved global health issue. There are compelling intrinsic and moral reasons to ensure that children attain their optimal growth potential facilitated via promotion of healthy living conditions. Investments in efforts to ensure that children's growth is not faltered also have substantial instrumental benefits in terms of cognitive and economic development. Using the case of India, we critique three prevailing approaches to reducing undernutrition among children: an over ‐ reliance on macroeconomic growth as a potent policy instrument, a disproportionate focus on interpreting undernutrition as a demand ‐ side problem and an over ‐ reliance on unintegrated single ‐ factorial (one at a time) approaches to policy and research. Using existing evidence, we develop a case for support ‐ led policy approach with a focus on integrated and structural factors to addressing the problem of undernutrition among children in India. Key messagesEliminating child undernutrition is important from an intrinsic perspective and offers considerable instrumental benefits to individual and society.Evidence suggests that an exclusive reliance on a growth ‐ mediated strategy to eliminate stunting needs to be reconsidered, suggesting the need for a substantial support ‐ led strategy.Interpreting and addressing undernutrition as a demand ‐ side problem with proximal single ‐ factorial interventions is futile.There is an urgent need to develop interventions that address the broader structural and upstream causes of child undernutrition.

Empirical evidence suggests that macroeconomic growth in India is not correlated with any substantial reductions in the prevalence of child undernutrition over time. This study investigates the two commonly hypothesized pathways through which macroeconomic growth is expected to reduce child undernutrition: (1) an increase in public developmental expenditure and (2) a reduction in aggregate income ‐ poverty levels. For the anthropometric data on children, we draw on the data from two cross ‐ sectional waves of National Family Health Survey conducted in 1992–1993 and 2005–2006, while the data for per capita net state domestic product and per capita public spending on developmental expenditure and headcount ratio of poverty were obtained from the Reserve Bank of India and the Government of India expert committee reports. We find that between 1992–1993 and 2005–2006, state ‐ level macroeconomic growth was not associated with any substantial increases in public development expenditure or substantial reductions in poverty at the aggregate level. Furthermore, the association between changes in public development expenditure or aggregate poverty and changes in undernutrition was small. In summary, it appears that the inability of macroeconomic growth to translate into reductions in child undernutrition in India is likely a consequence of the macroeconomic growth not translating into substantial investments in development expenditure that could matter for children's nutritional status and neither did it substantially improve incomes of the poor, a group where undernutrition is also the highest. The findings here build a case to advocate a ‘support ‐ led’ strategy for reducing undernutrition rather than simply relying on a ‘growth ‐ mediated’ strategy. Key messagesIncreases in macroeconomic growth have not been accompanied by substantial increases in public developmental spending or reduction in aggregate poverty headcount ratio in India.Association between increases in public development expenditure or poverty headcount ratios and changes in child undernutrition, in particular, child stunting, is small to null.Reducing the burden of undernutrition in India cannot be accomplished solely relying on a growth ‐ mediated strategy, and a concerted support ‐ led strategy is required.

We use a representative sample of 2561 children 0–23 months old to identify the factors most significantly associated with child stunting in the state of Maharashtra, India. We find that 22.7% of children were stunted, with one ‐ third (7.4%) of the stunted children severely stunted. Multivariate regression analyses indicate that children born with low birthweight had a 2.5 ‐ fold higher odds of being stunted [odds ratio (OR) 2.49; 95% confidence interval (CI) 1.96–3.27]; children 6–23 months old who were not fed a minimum number of times/day had a 63% higher odds of being stunted (OR 1.63; 95% CI 1.24–2.14); and lower consumption of eggs was associated with a two ‐ fold increased odds of stunting in children 6–23 months old (OR 2.07; 95% CI 1.19–3.61); children whose mother's height was < 145 cm, had two ‐ fold higher odds of being stunted (OR 2.04; 95% CI 1.46–2.81); lastly, children of households without access to improved sanitation had 88% higher odds of being severely stunted (OR 1.88; 95% CI 1.17–3.02). Attained linear growth (height ‐ for ‐ age z ‐ score) was significantly lower in children from households without access to improved sanitation, children of mothers without access to electronic media, without decision making power regarding food or whose height was < 145 cm, children born with a low birthweight and children 6–23 months old who were not fed dairy products, fruits and vegetables. In Maharashtra children's birthweight and feeding practices, women's nutrition and status and household sanitation and poverty are the most significant predictors of stunting and poor linear growth in children under 2 years. Key messagesOne in five (22.7%) of children 0–23 months old in the state of Maharashtra were stunted, and one ‐ third (7.4%) of the stunted children were severely stunted.Birthweight, child feeding, women's nutrition and household sanitation were the most significant predictors of stunting and poor linear growth in children under 2 years.Children born to mothers whose height was below 145 cm, had two ‐ fold higher odds of being stunted; children born with a low birthweight had a 2.5 ‐ fold higher odds of being stunted.Low feeding frequency and low consumption of eggs, dairy products, fruits and vegetables were associated with stunting and poor linear growth in children 6–23 months old.Children of households without access to improved sanitation had 88% higher odds of being severely stunted.

Despite the broad consensus that investments in nutrition-sensitive programmes are required to reduce child undernutrition, in practice empirical studies and interventions tend to focus on few nutrition-specific risk factors in isolation. The 2015–16 National Family Health Survey provides the first opportunity in more than a decade to conduct an up-to-date comprehensive evaluation of the relative importance of various maternal and child health and nutrition (MCHN) factors in respect to child anthropometric failures in India. The primary analysis included 140,444 children aged 6–59 months with complete data on 20 MCHN factors, and the secondary analysis included a subset of 25,603 children with additional paternal data. Outcome variables were stunting, underweight and wasting. We conducted logistic regression models to first evaluate each correlate separately in age- and sex-adjusted models, and then jointly in a mutually adjusted model. For all anthropometric failures, indicators of past and present socioeconomic conditions showed the most robust associations. The strongest correlates for stunting were short maternal stature (OR: 4.39; 95%CI: 4.00, 4.81), lack of maternal education (OR: 1.74; 95%CI: 1.60, 1.89), low maternal BMI (OR: 1.64; 95%CI: 1.54, 1.75), poor household wealth (OR: 1.25; 95%CI: 1.15, 1.35) and poor household air quality (OR: 1.22; 95%CI: 1.16, 1.29). Weaker associations were found for other correlates, including dietary diversity, vitamin A supplementation and breastfeeding initiation. Paternal factors were also important predictors of anthropometric failures, but to a lesser degree than maternal factors. The results remained consistent when stratified by children's age (6–23 vs 24–59 months) and sex (girls vs boys), and when low birth weight was additionally considered. Our findings indicate the limitation of nutrition-specific interventions. Breaking multi-generational poverty and improving environmental factors are promising investments to prevent anthropometric failures in early childhood. • We evaluated a comprehensive set of correlates for child anthropometric failures. • Parental anthropometry, socioeconomic and environmental correlates were strongest. • Weaker and inconsistent associations were found for other correlates. • No systematic difference was found by children's age and sex. • Nutrition-sensitive programs should accompany nutrition-specific interventions.
