P081 Sleep health in community-dwelling midlife women and associations with menopausal symptoms: a cross-sectional study

Abstract Introduction Sleep health or, ‘healthy sleep’, is a multidimensional construct, more than the absence of a sleep disorder. Menopausal women often experience sleep disturbances, yet the impact of menopausal symptoms on the likelihood of poorer sleep health remains unclear. This study examined how domains of menopausal symptoms (vasomotor, psychosocial, physical and sexual) relate to sleep health in Australian middle-aged women. Methods A total of 150 healthy women, aged 40-64 years, participated in this cross-sectional study. Sleep health was measured using the Ru-SATED questionnaire (scores ranging from 0 [poor sleep health] to 12 [good sleep health]), and sleep duration and efficiency were collected with actigraphy. Recommended sleep duration and efficiency were based on National Sleep Foundation (NSF) guidelines. Domains of menopausal symptoms were assessed with the Menopause-specific Quality of Life (MENQOL) questionnaire. Data were analysed through ordinal and binomial regression. Results The average Ru-SATED score was 9.2±2.2. According to NSF guidelines, only 20.0% of participants slept the recommended 7 to 9 hours, and 31.3% had the recommended sleep efficiency (≥85.0%). After adjusting for covariates, greater psychosocial symptoms were significantly associated with poorer sleep health (β=-0.437, p=0.002). Menopausal symptoms were not significantly associated with actigraphy measured sleep duration or efficiency. Discussion Most midlife women in this study did not meet the NSF sleep health recommendations. Psychosocial symptoms were associated with poorer sleep health in midlife women, consistent with research in other populations. Further research into factors beyond menopausal symptoms contributing to the likelihood of poor sleep health in middle-aged women is warranted.
