Study Objectives: Determine effects of low-dose estradiol and low-dose venlafaxine on self-reported sleep measures in menopausal women with hot flashes. Design: 3-arm double-blind randomized trial. Participants assigned in a 2: 2: 3 ratio to 17 beta estradiol 0.5 mg/day (n = 97), venlafaxine XR 75 mg/day (n = 96), or placebo (n = 146) for 8 weeks. Setting: Academic research centers. Participants: 339 community-dwelling perimenopausal and postmenopausal women with = 2 bothersome hot flashes per day. Measurements and Results: Insomnia symptoms (Insomnia Severity Index [ISI]) and sleep quality (Pittsburgh Sleep Quality Index [PSQI]) at baseline, week 4 and 8; 325 women (96%) provided ISI data and 312 women (92%) provided PSQI data at baseline and follow-up. At baseline, mean (SD) hot flash frequency was 8.1/day (5.3), mean ISI was 11.1 (6.0), and mean PSQI was 7.5 (3.4). Mean (95% CI) change from baseline in ISI at week 8 was -4.1 points (-5.3 to -3.0) with estradiol, -5.0 points (-6.1 to -3.9) with venlafaxine, and -3.0 points (-3.8 to -2.3) with placebo (P overall treatment effect vs. placebo 0.09 for estradiol and 0.007 for venlafaxine). Mean (95% CI) change from baseline in PSQI at week 8 was -2.2 points (-2.8 to -1.6) with estradiol, -2.3 points (-2.9 to -1.6) with venlafaxine, and -1.2 points (-1.7 to -0.8) with placebo (P overall treatment effect vs. placebo 0.04 for estradiol and 0.06 for venlafaxine). Conclusions: Among perimenopausal and postmenopausal women with hot flashes, both low dose oral estradiol and low-dose venlafaxine compared with placebo modestly reduced insomnia symptoms and improved subjective sleep quality.
