m 2 BMI, and aOR, 55 (95% CI, 41-75) with BMI 30 kg/m 2 . The probability of GH recurrence increased as BMI increased. For women with first-pregnancy hypertensive disorders, the likelihood of second-pregnancy GH increased from 12 to 26% with 15 to 50 kg/m 2 BMI. Adjusted OR for GH was 42 (95% CI, 26-66) for women with 25 kg/m 2 BMI, and in obese women (BMI 30 kg/m 2 ) the second-pregnancy GH aOR (95% CI) was 56 (33-95). Increased adiposity was associated with higher likelihood of second-pregnancy PE; aOR 1.4 (95% CI, 0.9-2.1) among women with normal BMI, aOR 1.9 (95% CI, 1.2-3.1) among obese women.This study found an increased risk of complications during the second pregnancy as maternal pre-pregnancy weight and BMI increased, especially in conjunction with first-pregnancy complications (ie, GDM and GH). Even modest adjustments in BMI could potentially improve maternal and neonatal outcomes. As the study data uses self-reported data and the data pool of women with pregestational diabetes and chronic hypertension was limited, further research should be conducted to confirm results.
