Figure 3. Maternal antioxidant intake-specific associations between PM2.5 exposure over gestation and newborn relative telomere length (rLTL).

Figure 3.

This figure demonstrates the maternal antioxidant intake-specific associations between PM2.5 exposures over pregnancy and rLTL using a BDLIM assuming week-specific effects for children born to mothers reporting low versus high antioxidant intake during pregnancy. Models were adjusted for maternal age, self-reported ethnicity, marital status, education level, LSC-R, and infant sex. Panel A demonstrates the cumulative effect on newborn rLTL per 1 μg/m3 increase in PM2.5 by maternal antioxidant intake [cumulative effect estimate: low maternal antioxidant intake = −0.31 (95% CI −0.55 to −0.06) vs high maternal antioxidant intake = −0.07 (95% CI −0.34 to 0.17) per 1μg/m3 increase in PM2.5.5]. In panel B, the y-axis represents the change in rLTL per 1 μg/m3 increase in PM2.5. The x-axis represents gestational age in weeks. The solid line shows the estimated change in rLTL while gray areas indicate 95% credible intervals (CIs). No sensitive window is identified.
