To investigate the association between various sleep problems and self-rated health (SRH), a total of 43,092 (34,164 men and 8,928 women) employees were surveyed by means of a self-administered questionnaire. The risk of suboptimal (poor, very poor) SRH associated with sleep problems was estimated using multivariable logistic regression with odds ratios (ORs) as measures of associations. Because the prevalence of suboptimal SRH differed by sex (men 29.4% and women 34.1%, P < 0.001), the analyses were done separately for men and women. Employees sleeping less than 6 hrs/day (OR = 1.39 for men, 1.40 for women), with difficulty initiating sleep (OR=4.44 for men, 3.85 for women), with difficulty maintaining sleep (OR=5.72 for men, 4.85 for women), with early morning awakening (OR=3.87 for men, 4.25 for women), with difficulty waking up in the morning (OR=3.30 for men, 3.40 for women), feeling tired when waking up in the morning (OR=4.97 for men, 4.82 for women), and excessive daytime sleepiness at work (OR=2.34 for men, 2.11 for women) had a significantly higher odds of suboptimal SRH compared to those without sleep problems. The association between sleep problems and suboptimal SRH did not differ between men and women. In conclusion, the data point to an independent relationship between sleep problems and suboptimal SRH among Japanese employees.
为了研究各种睡眠问题与自评健康状况（SRH）之间的关联，我们通过自填式问卷对总共43092名员工（34164名男性和8928名女性）进行了调查。使用多变量逻辑回归，以比值比（OR）作为关联度量，估计与睡眠问题相关的次优（差、非常差）SRH风险。由于次优SRH的患病率因性别而异（男性为29.4%，女性为34.1%，P<0.001），因此对男性和女性分别进行了分析。与没有睡眠问题的员工相比，每天睡眠时间少于6小时的员工（男性OR=1.39，女性OR=1.40）、入睡困难的员工（男性OR=4.44，女性OR=3.85）、维持睡眠困难的员工（男性OR=5.72，女性OR=4.85）、早醒的员工（男性OR=3.87，女性OR=4.25）、早晨醒来困难的员工（男性OR=3.30，女性OR=3.40）、早晨醒来时感到疲倦的员工（男性OR=4.97，女性OR=4.82）以及工作时白天过度嗜睡的员工（男性OR=2.34，女性OR=2.11），其次优SRH的几率显著更高。睡眠问题与次优SRH之间的关联在男性和女性之间没有差异。总之，数据表明日本员工的睡眠问题与次优SRH之间存在独立关系。
