Menopause hormone therapy and complementary alternative medicine, quality of life, and racial/ethnic differences: the Study of Women's Health Across the Nation (SWAN)

Abstract

Objective: We hypothesized that, among midlife women with vasomotor and/or genitourinary symptoms of menopause, (1) hormone therapy (HT) compared with complementary alternative medicine (CAM) will be associated with higher quality of life (QoL), and (2) race/ethnicity would modify associations of HT and CAM with QoL.

Methods: Cross-sectional and longitudinal analyses of QoL in the Study of Women's Health Across the Nation participants using HT, CAM, or both. Women ( n = 2,514) completed a CAM use questionnaire and QoL assessments at baseline and every 1 to 2 years from 2002 to 2013. Associations between QoL and treatment, adjusted for covariates, and race/ethnicity-by-treatment interactions were analyzed using linear and mixed effects regression models.

Results: During 7.8 (SD, 2.9) years of follow-up, 732 women (29%) reported HT of 2.4 (SD, 1.7) years, and 798 women (32%) reported CAM use of 2.1 (SD, 1.4) years. Overall, neither HT nor CAM was associated with QoL. However, the treatment-by-race/ethnicity interaction was significant for self-reported QoL ( P = 0.034 at baseline, P = 0.044 longitudinal). Among White women, self-reported QoL was higher in HT-only users than in those who used neither ( P = 0.030; d = 0.11; 95% confidence interval, 0.01-0.21). In contrast, Black women using HT only had lower self-reported QoL compared with Black women using neither ( P = 0.027; d = -0.21; 95% confidence interval, -0.40 to -0.02).

Conclusion: Comparisons between treatment type within each racial/ethnic group yielded significant differences in self-reported QoL. Clinicians should be aware of racial/ethnic differences in treatment preferences when counseling patients on treatment options for menopausal symptoms to provide optimal care.
