Among a cohort of postmenopausal women, vaginal estrogen use was not associated with a higher risk of cardiovascular disease (CVD) or cancer, according to a recent study. Participants from the Nurses’ Health Study (1982-2012) were not users of systemic hormone therapy at the start of the study or during follow-up. Vaginal estrogen use was self-reported on the biennial questionnaires. Researchers found:
- Over 18 years of follow-up and after adjusting for covariates, risk for CVD, cancer, and hip fracture were not different between users and nonusers of vaginal estrogen.
- No statistically significant increase in risk of any health outcome was observed with vaginal estrogen use.
- The stratified results were generally similar to those for the total cohort when researchers examined associations by hysterectomy status in sensitivity analysis.
