Impact of Wildland Fire Smoke PM_2.5 on Birth Weight in California.

ABSTRACT: The increase in the frequency, duration, and intensity of wildland fires is a significant source of air pollution that can impact perinatal outcomes. This study assessed associations between wildfire fine particulate matter <2.5 μm (PM_2.5) and adverse birth weight outcomes among singleton term births in California for 2007-2018. Exposure was assessed using bias-corrected Community Multiscale Air Quality Model, linked to residence at delivery. Logistic and linear regression models estimated associations between average daily wildfire PM_2.5 and birth weight outcomes, adjusting for individual-level sociodemographic covariates and seasonality. We conducted race/ethnicity-stratified analyses to assess whether the influence of wildfire PM_2.5 differed among racial
