摘要

AbstractBackgroundExposure to PM2.5(fine particulate matter ObjectivesWe examined whether PM2.5exposures during pregnancy were associated with birthweight in an integrated rural-urban, mother-child cohort in the state of Tamil Nadu, India.MethodsWe recruited 1285 pregnant women in the first trimester of pregnancy from primary health care centers and urban health posts and followed them until birth to collect antenatal care data and birthweight. We estimated pregnancy period PM2.5exposures through direct serial measurements of 24-h household PM2.5concentrations, performed across each trimester. Mothers also completed detailed questionnaires to provide data on covariates related to household, socio-economic, demographic and maternal health characteristics. The association between PM2.5exposures and birth weight was assessed using linear and logistic regression models that controlled for potential confounders.ResultsA 10-μg/m3increase in pregnancy period PM2.5exposures was associated with a 4g (95% CI: 1.08g, 6.76g) decrease in birthweight and 2% increase in prevalence of low birthweight [odds ratio(OR) = 1.02; 95%CI:1.005,1.041] after adjusting for gestational age, infant sex, maternal BMI, maternal age, history of a previous low birth weight child, birth order and season of conception.ConclusionsThe study provides some of the first quantitative effects estimates for linking rural-urban PM2.5exposures and birthweight in India, adding important evidence for this association from high exposure settings in LMICs, that also experience dual health burdens from ambient and household air pollution. Study results also point to the need for considering maternal PM2.5exposures alongside other risk factors for low birthweight in IndiaHighlights•Provides E-R relationships between PM2.5and birth-weight in high exposure settings.•Examines the association in a rural-urban, mother-child cohort in India.•Estimates a 4g decrease in birth-weight per 10-μg/m3increase in PM2.5exposures.•Estimates a 2% increase in low birth-weight per 10-μg/m3increase in PM2.5exposures.•Maternal PM2.5exposures may be an important risk factor for low birth-weight in India.
