Abstract
BACKGROUND: Lack of toilets and the widespread practice of open defecation may contribute to India's large burden of child undernutrition. OBJECTIVES: We examine whether a large national sanitation campaign launched in 2014, the Swachh Bharat Mission (SBM), precedes a reduction in stunting and wasting among under 5-y-old (u5) children in India. METHODS: In this observational study, we used district-level data from before (2013-2014) and after (2015-2016) SBM from 3 national surveys to derive, as our outcomes, the percentage of u5 children per district who are stunted and wasted. We defined our exposures as 1) binary indicator of SBM and 2) percentage of households with toilets per district. Our analytic sample comprised nearly all 640 Indian districts (with ∼1200 rural/urban divisions per district per time point). Linear regression analyses controlled for baseline differences in districts, linear time trends by state, and relevant covariates. RESULTS: Relative to pre-SBM, u5 stunting declines by 0.06% (95% CI: -0.10, -0.01; P = 0.009) with every percentage increase in households with toilets post-SBM. Rural regions and districts with higher pre-SBM toilet availability show greater decline in u5 stunting post-SBM. CONCLUSIONS: An increase in toilet availability on a national scale, precipitated by the SBM sanitation campaign, is associated with a reduction in undernutrition among u5 children in India over the early phase of the campaign.
