To evaluate the effect of climacteric vasomotor symptoms on sleep quality measured by self-report and polysomnography in postmenopausal women.
Seventy-one healthy postmenopausal women were recruited, of whom 63 completed the study.
Each subject recorded climacteric symptoms and subjective sleep quality for 14 days.
Sleep quality was evaluated objectively by all-night polysomnography using the static charge-sensitive bed.
During polysomnography, a high frequency of climacteric vasomotor symptoms was not associated with changes in sleep latency, percentage of sleep stages, number of arousals, sleep efficiency, or total sleep time.
However, a high frequency of climacteric vasomotor symptoms (range 0-8.9, r=60, P<. 001), somatic symptoms (range 0-5.0, r=25-44, P<. 05), and mental symptoms (range 0-5.0, r=41-51, P<. 001) was related to impaired subjective sleep quality.
In stepwise regression analysis, 32% of the impairment in subjective sleep quality was explained by vasomotor symptoms (P<. 001), 14% by palpitations (P<. 001), and 4% by mood instability (P=029).
High body mass index predicted impaired objective sleep quality, such as prolonged latencies to stage-2 sleep (r=27, P=031) and slow-wave sleep (r=51, P=003) and decreased oxygen saturations (r=-54, P<. 001).
Older women had decreased sleep efficiency (r=-27, P=030) and lower oxygen saturations (r=-36, P=004).
Serum estradiol level had only a minor effect on objective sleep quality. (...)
