a, Of the 4,851 women enrolled in the VaHMP study, 613 pregnant and 1,969 non-pregnant women who reported no health complaints were analyzed in this project. A subset of 600 of these women (that is, 300 pregnant and 300 non-pregnant women, case-matched for self-reported race, gestational age at sampling and household income) was selected for analysis. Of these, there were 156 case-matched pairs of women with African ancestry, 61 case-matched pairs of women with European ancestry, and 83 case-matched pairs of women with Hispanic ancestry. These women were sampled at regular visits to VCU women’s health clinics. b, The 90 women (49 of African ancestry, 41 of European ancestry) forming the MOMS-PI Term Birth cohort were selected from a Phase 1 cohort (dark shade, pregnant women, N = 627) of women enrolled from women’s clinics at VCU. These participants were sampled longitudinally throughout pregnancy. 1st, 2nd and 3rd refer to the trimesters of pregnancy; PP, postpartum.
