Key result
Higher nighttime vasomotor symptoms linked to worse emotional well-being through greater sleep disturbance.
Why the study?
Most research evaluating the effect of menopause on mental health focuses on depression rather than short-term emotional well-being, and whether sleep disturbance mediates the impact of vasomotor symptoms on positive and negative well-being was unclear.
Does sleep disturbance mediate the association between vasomotor symptoms and emotional well-being in midlife postmenopausal women?

Effect estimate: b = -0.086
p-value: p=<0.05
Subjective sleep disturbance mediates the association between subjective nighttime vasomotor symptoms and worse short-term emotional well-being in midlife postmenopausal women.
Sleep disturbance may mediate vasomotor symptom effects on well-being; hypothesis-generating and requires prospective confirmation before clinical application.
OBJECTIVES: Most research evaluating the effect of menopause on mental health focuses on depression. However, short-term positive and negative emotional well-being are also key aspects of mental health. The domino hypothesis posits that vasomotor symptoms (VMS) impact mental health through sleep disturbance (SD). Thus, we evaluated SD as a mediator of the association of VMS with positive and negative emotional well-being in midlife women, using both subjective and objective measures of VMS and SD. STUDY DESIGN: Midlife women (N = 242; 98% postmenopausal; mean age 59.02 ± 4.43 years) enrolled in MsBrain I underwent 72 h of at-home monitoring of VMS, SD, and positive and negative emotional well-being. MAIN OUTCOME MEASURES: Nighttime VMS frequency measured via self-report and sternal skin conductance. SD (i.e., wake after sleep onset) measured via self-report and actigraphy. Positive and negative emotional well-being measured via ecological momentary assessment methods. RESULTS: In structural equation modeling of subjective symptoms, there was an indirect effect of higher nighttime VMS frequency on lower positive (b = -0.086, p < .05) and higher negative (b = 0.084, p < .05) emotional well-being through greater SD. For objective symptoms, VMS had no total, direct, nor indirect effect on emotional well-being (ps > 0.05). Only greater objectively assessed SD was associated with lower positive emotional well-being (b = -0.851, p < .05). CONCLUSIONS: Higher nighttime VMS frequency was indirectly associated with worse short-term emotional well-being through greater SD, but only when VMS and SD were measured subjectively. Greater objective SD was associated with lower positive emotional well-being only. Therefore, subjective and objective SD may be targeted to enhance the short-term emotional well-being of midlife women.

Wood et al. (2026) conducted an observational in Vasomotor symptoms in postmenopausal women (n=242). Nighttime vasomotor symptoms was evaluated on Positive and negative emotional well-being (b = -0.086, p=<0.05). Higher subjective nighttime vasomotor symptom frequency was indirectly associated with lower positive (b = -0.086, p<0.05) and higher negative emotional well-being through greater sleep disturbance.
