To evaluate whether single measurements of serum estradiol (E), estrone (E) and sex hormone-binding globulin (SHBG) concentration distinguishes between women with and without menopausal symptom bother.
We analyzed baseline data from two clinical trials conducted in 2012-2017: MsFLASH 03 (178 peri-/post-menopausal women aged 40-62 years with bothersome vasomotor symptoms, mean age 54) and MsFLASH 05 (181 post-menopausal women aged 45-70 years with moderate-to-severe vulvovaginal symptoms, mean age 61).
Symptom bother (hot flushes or flashes, night sweats, sweating, aching in muscles and joints, change in sexual desire, vaginal dryness during intercourse, and avoiding intimacy) in the past month was assessed using the Menopause-Specific Quality of Life questionnaire. Using logistic regression, we calculated the area under the receiver operating characteristic curve (AUC) values for E, E, and SHBG concentration in relation to being at least somewhat bothered (symptom bother score ≥3) by each symptom within each trial study population.
AUC values (95% confidence interval) ranged between 0.51 (0.41-0.60) and 0.62 (0.53, 0.72) for MsFLASH 03 and between 0.51 (0.42, 0.59) and 0.64 (0.53, 0.75) for MsFLASH 05. There was little evidence of associations between serum hormone levels and bother by a given menopausal symptom.
These findings do not support the clinical utility of a single measurement of serum of E, E, or SHBG concentrations in differentiating between women who are bothered by a given menopausal symptom and those who are not.
