Covariates of diarrhoea among under-five children in India: Are they level dependent?

Abstract

Program interventions like access to improved water supply, sanitation and hygiene do not have a systematic response to the aggregate health outcomes. Therefore, this is an attempt at recognising the concept of level sensitivity while verifying the association between prevalence of diarrhoea in under-five children in a district and its corresponding coverage of improved water supply and sanitation and hygiene. Information obtained in the DLHS—4 including 275 districts from 19 states and 2 union territories of India forms the database for this analysis. Universal access to safe drinking water, improving coverage of sanitation in a district beyond 71 percent across the country and beyond 78 percent among the non-south DLHS districts, has the potential to realise reductions in the prevalence of diarrhoea in under-five children in a district. The effect of improved sanitation seems to work synergisti-cally with these indicators only at better levels of prevalence of diarrhoea in under-five children in a district. This offers lessons for the Clean India Mission in terms of universalising access to safe water and coverage up to three-fourths of households with sanitation in a district for the positive externalities to manifest in reduced prevalence of diarrhoea in under-five children.
