Estimating the burden of anaemia in women of reproductive age attributable to wildfire-sourced fine particulate matter: a multicentre cross-sectional study in low- and middle-income countries.

ABSTRACT: Climate change has been assumed as a key contributor to global undernutrition. One possible channel is that global warming increases air pollution exposure by causing more and more wildfires. This study examined the effect of wildfire-sourced particulate matter (PM)_2.5 exposure on anaemia in women of reproductive age (WRA), a dominating form of undernutrition across the low- and middle-income countries (LMICs). We collected haemoglobin measurements of 1 549 972 WRA from 85 Demographic and Health Surveys (DHS) in 45 LMICs between 2004 and 2021. Wildfire-sourced PM_2.5 exposure was estimated through a synthesis of ground observations, satellite remote sensing measurements and the Goddard Earth Observing System with Chemistry (GEOS-Chem) model simulations. The effects on
