Abstract: Evidence suggests that the prevalence of insomnia is higher among divorced or separated individuals compared to married individuals; however, very few studies have examined the relationship between marital status and daytime sleepiness. This cross-cultural study examined the relationships between marital status and excessive daytime sleepiness (EDS) in the general population. A web-based survey using a questionnaire on daytime sleepiness was conducted on 1,500 participants from the United States, Australia, and China. Statistical analyses included a multivariate logistic regression analysis and ANOVA. Divorced participants had a significantly greater odds of showing EDS, odds ratio = 1.90 (95% confidence interval [1.07, 3.37], p < 0.05), compared to married participants. Moreover, the ANOVA results revealed that divorced, separated, or widowed individuals reported higher daytime sleepiness scores compared to married and unmarried individuals. In addition, daytime sleepiness scores decreased with advancing age. Our findings indicate that divorced, separated, or widowed individuals reported higher EDS compared to married individuals. Future studies need to comparatively examine the effectiveness of co-habitants and bed partnersí routines on improving EDS.
