No Magic Bullets: Insights on Drivers of Stunting Decline from an Analysis of Subnational Success Cases in India
Abstract 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 leadership, targeting multiple determinants and improving implementation systems. Supportive civil society, political and bureaucratic leadership motivated by the well-being of communities remain crucial. Funding Sources Bill & Melinda Gates Foundation through POSHAN, led by IFPRI.
