Tests for effect modification by preterm delivery: p=0.08 for chronic hypertension, p=0.68 for type 2 diabetes mellitus, and p=0.03 for hypercholesterolemia.

Model 1 is adjusted for age at first birth (years), age in 1989 (years), race/ethnicity (African-American, Latina, Asian, Caucasian (ref), other), and parental education (<9, 9–11, 12, 13–15, ≥16 years (ref)).

Model 2 is additionally adjusted for physical activity at ages 18–22 (never, 1–3 (ref), 4–6, 7–9, 10–12 mo/yr), pre-pregnancy smoking (never (ref), past, current), pre-pregnancy BMI (<18.5, 18.5–24.9 (ref), 25–29.9, ≥30 kg/m²), pre-pregnancy alcohol consumption (none (ref), ≤1 drink/week, 2–6/week, ≥1/day), pre-pregnancy Alternative Healthy Eating Index (AHEI) score (quintiles with the fifth quintile (ref) representing the healthiest diet category), pre-pregnancy oral contraceptive use (never (ref), <2, 2-<4, ≥4 years), and family history of chronic hypertension (yes/no; chronic hypertension model only) and family history of type 2 diabetes mellitus (yes/no; type 2 diabetes mellitus model only).

These results are drawn from 6 different models—one model with hypertensive disorders in pregnancy and normotensive first pregnancies split out by term and preterm delivery (i.e. 4 exposure categories) and another model with preeclamptic, gestational hypertensive, and normotensive first pregnancies split out by term and preterm deliveries (i.e. 6 exposure categories) for each of the 3 CVD risk factor outcomes; normotensive term served as the reference group for all contrasts. Results for women with normotensive preterm are not shown above but were obtained within the same models: fully-adjusted chronic hypertension HR=1.10 (95% CI: 1.04, 1.16); type 2 diabetes mellitus HR=1.20 (1.06, 1.35); hypercholesterolemia HR=1.08 (1.03, 1.12).
