Aim The association of air pollution with prevalence of undernutrition indices (namely, anaemia, stunting, wasting and underweight) among under-five children in India was investigated. Methods Estimates of population weighted annual average gridded PM 2.5 concentrations and proportion of households using solid cooking fuel (HSCF usage percent) during 2017 in India, reflecting the magnitude of ambient and household air pollution respectively, were extracted in a state-wise manner from India State Level Disease Burden Initiative (ISLDBI) reports. Their relationships with the corresponding prevalence of anaemia, underweight, wasting and stunting in under-five children were analysed. Results The state-level PM 2.5 concentrations (mean: 65.5 µg/m 3 ; median: 49.2 µg/m 3 ; range: 17.3–209.0 µg/m 3 ) correlated significantly (P < 0.01) with anaemia (r = 0.65), stunting (r = 0.58) and underweight (r = 0.50) prevalence; while HSCF usage (mean: 49.3%; median: 46.0%; range: 1.9–81.5%) correlated significantly (P < 0.01) with stunting (r = 0.69) and underweight (r = 0.58) prevalence. When examined across median cut-offs and after adjusting for socio-demographic index, the association of anaemia prevalence with PM 2.5 concentrations persisted. This association was maintained even after controlling for the coverage of anaemia-specific interventions (namely, iron supplements and deworming medications). The mean difference in PM 2.5 concentrations between the high and low PM 2.5 states was 58.6 µg/m 3 , which accounted for 11.8% higher anaemia prevalence in the former as compared to the latter. Conclusion The burden of childhood undernutrition, particularly anaemia, in India may be linked to PM 2.5 levels. To mitigate this burden, it may be necessary to complement the ongoing nutritional interventions with air pollution control measures. [ABSTRACT FROM AUTHOR]
