Study ObjectivesTo analyze relationships between spouses' sleep problems and their partners' physical health, mental health, well-being, social involvement, and marital quality in a sample of older persons.DesignThe Alameda County Study is a population-based longitudinal study focusing on behavioral factors associated with health and mortality.SettingParticipants completed questionnaires for the sixth wave of data collection (1999).Participants405 couples (810 husbands and wives aged 51 to 94 years).Measurements And ResultsParticipants were asked how often they had experienced difficulty falling asleep, waking up in the middle of the night, and waking up very early in the morning over the past month. Response sets ranged from "never" to "often." Scores were summed. Analyses included multivariate statistical models using generalized estimating equations to adjust for paired data as well as partner age, sex, chronic conditions, financial problems, and own sleep problems. Although partners' associations with negative outcomes were stronger for their own sleep problems, spouses' sleep problems were associated with partners' poor health, depressed mood, poor mental health, unhappiness, low optimism, feeling left out, not satisfied with relationships, and unhappy marriage, even after adjusting for the partners' sleep problems. We found no sex differences in associations between spouses' sleep problems and partners' outcomes.ConclusionsAlthough data are cross-sectional, findings suggest that spouses' sleep problems negatively impact partners' health and well-being. Our analyses emphasize the importance of treating sleep problems to promote the health and well-being of both affected individuals and their partners.
