Association between body mass index and chronic hypertension in patients with hypertension disorders of pregnancy one-year postpartum.

Objectives: To determine the association between body mass index (BMI) and chronic hypertension (CHTN) one-year postpartum following pregnancies complicated by hypertensive disorders of pregnancy (HDP).

Study Design: A retrospective cohort study of patients with HDP (gestational hypertension or preeclampsia) in a single Midwestern academic center from 2014 to 2018. The primary outcome was CHTN at one-year postpartum, defined as systolic blood pressure ≥ 130 mmHg or diastolic blood pressure ≥ 80 mmHg or taking antihypertensive medication at one-year postpartum.
