Abstract
Objectives: While it has been reported that women with uterine fibroids or endometriosis are commonly overweight and hypertensive, the association between non-malignant gynecological diseases and the risk of hypertension has been little studied prospectively. The aim of this study was to investigate in a large French cohort of women whether a history of hysterectomy, uterine fibroids, or endometriosis was prospectively related to an increased risk of incident hypertension.
Study design: We analyzed 50,286 women from the E3N cohort who were free of hypertension at baseline, with a median follow-up of 16.4 years.
Main outcome measures: Gynecological diseases were based on self-report. Cox proportional hazards models with age as the timescale were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Covariates included smoking status, body mass index (BMI), physical activity, and hormonal factors.
Results: A total of 12,073 women (24%) developed hypertension during follow-up. Women with a history of hysterectomy had an increased risk of incident hypertension, which persisted after adjustment for potential confounding factors (adjusted HR=1.18, 95% CI 1.12-1.24). Risk was similar in women with hysterectomy with or without oophorectomy. Risk of hypertension was higher in women with a history of endometriosis (HRendometriosis 1.19, 95%CI 1.11-1.22) or uterine fibroids (HRfibroids 1.18, 95%CI 1.13-1.22), irrespective of hysterectomy. Associations were similar after further adjustment for BMI.
Conclusions: Hysterectomy and non-malignant gynecological diseases were associated with an increased risk of hypertension in this large prospective study. Women with these conditions may benefit from blood pressure monitoring. ClinicalTrials.gov identifier: NCT03285230.
