Abstract | BACKGROUND: METHODS AND RESULTS: This analysis was conducted on 89 914 women in the Women's Health Initiative (WHI) Observational Study. Participants reported demographic characteristics, medical history, dietary habits, physical activity, medications, and previous hysterectomy (with or without oophorectomy). Baseline weight, height, waist circumference, and blood pressure were measured. CVD events were ascertained during 5.1 years of mean follow-up and adjudicated with standard criteria. Black, Hispanic, and American Indian women had higher rates of hysterectomy than white women (52.9%, 44.6%, and 49.2% versus 40.0%, respectively), and Asian/Pacific Islander women had lower rates (33.8%). Women with a hysterectomy (regardless of oophorectomy status) had an adverse risk profile at baseline compared with women with no hysterectomy, including a higher proportion of hypertension, diabetes, high cholesterol, obesity, and lower education, income, and physical activity (all P<0.01). Total mortality and fatal and nonfatal CVD were higher among women with a hysterectomy. Hysterectomy (regardless of oophorectomy status) was a significant predictor of CVD (HR: 1.26, P<0.001). After adjustment for demographic variables and CVD risk factors, the effect was reduced and nonsignificant. CONCLUSIONS: Women with a hysterectomy had a worse risk profile and higher prevalence and incidence of CVD in this cohort. Multivariate models suggest that hysterectomy is not the major determinant of this outcome; rather, CVD risk may be due to the more adverse initial risk profile of women who had undergone hysterectomy.
