The association of early-life exposure to ambient PM_2.5 and later-childhood height-for-age in India: an observational study.

ABSTRACT:

Background

Children in India are exposed to high levels of ambient fine particulate matter (PM_2.5). However, population-level evidence of associations with adverse health outcomes from within the country is limited. The aim of our study is to estimate the association of early-life exposure to ambient PM_2.5 with child health outcomes (height-for-age) in India.

Methods

We linked nationally-representative anthropometric data from India's 2015-2016 Demographic and Health Survey (n = 218,152 children under five across 640 districts of India) with satellite-based PM_2.5 exposure (concentration) data. We then applied fixed effects regression to assess the association between early-life ambient PM_2.5 and subsequent height-for-age, analyzing
