Association of Maternal PM_2.5 Exposure with Preterm Birth and Low Birth Weight: A Large-Scale Cohort Study in Northern Thailand (2016-2022).

ABSTRACT: Air pollution exposure has been increasingly linked to adverse pregnancy outcomes. This study aimed to investigate the effects of PM_2.5 exposure throughout pregnancy on preterm birth, low birth weight (LBW), and small for gestational age (SGA). We analyzed a cohort of 16,965 pregnant women living in northern Thailand between 2016 and 2022. PM_2.5 concentration data were collected from two air quality monitoring stations operated by the Pollution Control Department (PCD) of Thailand. Logistic regression models were used to assess the association between daily PM_2.5 exposure and pregnancy outcomes. PM_2.5 exposure at levels exceeding 37.5 μg/m³ throughout pregnancy significantly increased the risk of preterm birth (aOR = 2.19, p < 0
