This population-based study used multiple logistic regression to assess associations between ambient PM2.5 exposure and three health outcomes in Indian children under five: anaemia, acute respiratory infection (ARI), and low birth weight (LBW).
This population-based study used multiple logistic regression to assess associations between ambient PM2.5 exposure and three health outcomes in Indian children under five: anaemia, acute respiratory infection (ARI), and low birth weight (LBW). The study found that for every 10 µg/m³ increase in total PM2.5 mass, the odds increased for anaemia (10%), ARI (11%), and LBW (5%). However, the cumulative effect of specific chemical components like nitrate, elemental carbon, and ammonium was substantially larger. A key limitation is the cross-sectional design, which cannot establish causality.
