Description

<p>Objectives: This study was conducted to investigate and clarify the relationship between interpersonal problems, use of alcohol as aids to sleep, and sleep problems, i.e., sleep phase, sleep quality, and sleep quantity, among Japanese male workers.</p><p>Methods: A cross-sectional questionnaire survey was conducted in May, 2014. We analyzed total 280 male workers at two manufacturing business companies. 3-Dimensional Sleep Scale (3DSS) was used to assess sleep problems and measure sleep phase, sleep quality, and sleep quantity through scoring. To assess the use of alcohol as aids to sleep, we asked “Do you use alcohol as sleep aid? (yes/no),” and to assess interpersonal problems, we asked “In the past years, do you have any interpersonal problems? (yes/no).”</p><p>Results: In multiple logistic regression analyses, alcohol use as sleep aid was significantly associated with low sleep quantity score (OR [95%CI]=2.24 [1.15, 4.35]). Interpersonal problems were significantly associated with high sleep phase score (OR [95%CI]=0.39 [0.17, 0.87])and low sleep quantity score (OR [95%CI]=2.78 [1.19, 6.48]). None of the independent variables were significantly associated with sleep quality. Additionally, the interaction of use of alcohol as aids to sleep and interpersonal problems significantly affected the low sleep phase (OR [95%CI]=5.08 [1.29, 20.0]).</p><p>Conclusion: While use of alcohol as aids to sleep and interpersonal problems were associated with low sleep quantity scores, their interaction was associated with low sleep phase scores in Japanese male workers.</p>
