Figure 1. Association between maternal PM2.5 exposure and infant birthweight percentiles.

Figure 1.

A. Maternal PM2.5 exposure from 12 weeks prior to conception until 13 weeks gestation is inversely associated with infant birthweight percentiles. B. Among female infants, maternal PM2.5 exposure from 6 weeks prior to conception until 13 weeks gestation is inversely associated with birthweight percentiles. C. Among male infants, no association is observed between maternal PM2.5 exposure and birthweight percentiles. Stratifying our analyses by sex, an overall cumulative effect on infant birthweight percentiles due to a 1 ug increase in PM2.5 sustained across all lags is observed among female infants (−7.40, [95% CI: −14.78, −0.03]) but not among male infants (−2.72, [95% CI: −9.21, 3.77]).
