Figure 2. Associations between weekly PM2.5 levels over gestation and fat mass: interaction by sex.

Figure 2

This figure demonstrates the association between PM2.5 exposure over pregnancy and fat mass (kg) using BDLIM assuming week-specific effects. Models were adjusted for maternal age, race/ethnicity, education, pre-pregnancy BMI, and child’s age at anthropometry measurement. The y-axis represents the change in fat mass corresponding to per μg/m3 increase in PM2.5; the x-axis is gestational age in weeks. Solid lines show the predicted change in fat mass. Gray areas indicate 95% confidence intervals (CIs). A sensitive window is identified for the weeks where the estimated pointwise 95% CI (shaded area) does not include zero.
