N2 - Objectively measured sleep efficiency has recently been shown to be associated with health problems. Although several factors have previously been reported to be associated with sleep efficiency, most of these studies were conducted on older or younger adults, and the factors associated with sleep efficiency in healthy workers remain unknown. The aim of this study was to investigate the relationship between sleep efficiency and lifestyle factors using sleep measurement data recorded by an activity meter worn by workers. In total, 693 workers (male, 43.6%; mean age, 42.7 ± 11.3 years) were recruited from five offices in 2017. Sleep was measured over the period of 1 week by actigraphy. Workers’ attributes, lifestyle habits, and occupational stress were identified using a questionnaire, and the association of sleep efficiency with lifestyle, occupational stress, and attributes was explored by logistic regression analysis. A logistic regression analysis using attributes and occupational stress as adjustment variables revealed that “longer sleeping hours on weekends than on weekdays” [odds ratios (OR), 0.66; 95% confidence interval (CI), 0.47–0.94], “water ingestion at bedtime” [OR, 2.09; 95% CI, 1.28–3.41], and “smartphone use at bedtime” [OR, 1.90; 95% CI, 1.28–2.83] were associated with decreased sleep efficiency. This study found that lifestyle habits were associated with sleep efficiency among workers.
