No Magic Bullets: Insights on Drivers of Stunting Decline from an Analysis of Subnational Success Cases in India
OBJECTIVES: Global attention to reducing childhood stunting has increased the demand for guidance on translating policies into impact. Evidence from national-level success cases is emerging but little is known about how subnational entities can accelerate change. In India, despite a common national framework of programs/policies targeting many determinants of child growth, stunting reduction has varied across states. We aimed to understand drivers of change in stunting at state-level and to identify programmatic, social and political factors that contributed to these changes. METHODS: We studied three states that had achieved substantial stunting declines between 2005 and 2016 [Chhattisgarh (CG) 14 percentage points (pp); Gujarat (GJ) 13pp; Odisha (OD) 11 pp]. We used regression-decomposition analysis to assess contributions of various determinants of height-for-age Z-score (HAZ) using two rounds of national data. We reviewed nutrition-relevant policies and programs linked to these drivers of change and interviewed stakeholders in government, development partners (DPs), academia and civil society (n = 61) to understand how change occurred. RESULTS: Main contributors to gains in HAZ were coverage of health and nutrition interventions (21% CG; 11% GJ; 25% OD), household assets (10% CG; 13% GJ; 18% OD), and sanitation (7% CG; 6% GJ; 5% OD). Maternal education, age at marriage, community-level hygiene, and electrification also contributed. Political leadership and an outcome-focused vision were crucial for action. Although vision varied, capable administrators were able to secure adequate finances, strengthen implementation systems, and invest in state-specific innovations, creating an enabling environment for change. Varied actors, including civil society and DPs, played a catalytic role in spurring action through advocacy, technical and financial inputs, and vigilance. CONCLUSIONS: Similar drivers were responsible for stunting reduction in 3 states. Ingredients for success highlight the importance of political ...
