Figure 1. Associations of Weekly Air Pollution Exposure With Gestational Age z Score (BWZ) Among 628 Newborns in the Maternal and Developmental Risks from Environmental and Social Stressors Cohort.
All results were from distributed lag models adjusted for weekly temperature, maternal age, educational level, maternal prepregnancy body mass index, maternal ethnicity and nativity, cohabitation status, birth order, and enrollment time. Outcome estimation was based on per IQR increases in each air pollutant: particulate matter with aerodynamic diameter less than 2.5 μm (PM2.5), 4 μg/m3; particulate matter with aerodynamic diameter less than 10 μm (PM10), 12 μg/m3; nitrogen dioxide (NO2), 11 ppb; and ozone (O3), 15 ppb. Error bars indicate 95% CI.
