- Pregnancy history may predict subsequent hypertension in women.
Why this matters
- Identification of risk factors may allow for increased monitoring and interventions to reduce the burden of premature cardiovascular disease in women.
- Overweight/obese prepregnancy BMI, prepregnancy daily smoking, low educational level, poor diet quality, low physical activity level, and high weight retention at 6 months postpartum were associated with a greater risk for subsequent hypertension.
- Occasional and weekly alcohol consumption, a greater duration of oral contraceptive use before pregnancy, and breastfeeding daily at 6 months were associated with a decreased risk for subsequent hypertension.
- Women with pregnancies complicated by preeclampsia (HR, 8.4; 95% CI, 6.49-10.88) or gestational hypertension (HR, 12.07; 95% CI, 9.09-16.03), diabetes mellitus or gestational diabetes mellitus (HR, 3.36; 95% CI, 2.05-5.51), and preterm delivery (HR, 2.19; 95% CI, 1.59-3.02) were more likely to have hypertension within 10 years.
- Population-based cohort study.
- Cohort taken from the Norwegian Mother and Child Cohort Study (MoBa), a prospective population-based pregnancy cohort conducted by the Norwegian Institute of Public Health.
- Primary outcome was subsequent pharmacologically treated hypertension.
- Funding: Norwegian Institute for Public Health; University of Bergen.
- Family history lacking.
- Homogeneous population; results possibly not generalizable.
