There is a gender difference in the association between alcohol use and sleep patterns in middle-aged and older adults. Alcohol use is related to better subjective sleep quality in women but not in men.
Objectives: To examine associations between alcohol use and sleep in middled-aged/older adults and to test sex as a moderator of this relationship. Methods: Participants were 183 adults (46% female) ages 50 and above who consumed alcohol in the past year. Linear regressions tested sex as a moderator of associations between alcohol use and sleep parameters. Alcohol use was measured using the Alcohol Use Disorders Identification Test (AUDIT). Overall sleep health and sleep quality were assessed using the Pittsburgh Sleep Quality Index (PSQI), and pre-sleep arousal was assessed using the Pre-Sleep Arousal Scale. Results: Overall, 11% of participants screened positive for hazardous drinking (AUDIT scores of 7+/8+ for women/men), and 59% reported poor overall sleep health (scores > 5 on the PSQI). Alcohol use was not associated with overall sleep health (B = -0.25, p = .08) or pre-sleep arousal (B = 0.15, p = .64). However, contrary to hypotheses, more hazardous drinking was associated with better subjective sleep quality, only among women (B = -0.08, p =.009). Alcohol use was not associated with sleep quality among men (B = 0.01, p = .58). Associations remained significant when controlling for age, symptoms of anxiety and depression, body mass index, use of sleep medication, number of medical conditions, and chronic pain. Conclusions: Among middle-aged and older adults, alcohol use is more strongly associated with sleep patterns among women than men, when assessed concurrently (i.e., at the same time point). Findings support the need for further consideration of sex differences in associations between alcohol use and sleep. (c) 2022 Elsevier B.V. All rights reserved.
