本研究阐明了日本男性工人的晨昏类型与累积疲劳或抑郁状态之间的关系。对959名化工厂男性工人进行问卷调查，内容包括MEQ、SDS、CFSI、年龄、婚姻状况、睡眠指数、生活习惯、劳动负荷等。以SDS和CFSI为客观变量进行Logistic回归分析。有效问卷884例，按MEQ分为明确晨型（4.1%）、中度晨型（38.6%）、中间型（55.1%）、中度晚型（2.3%）和明确晚型（0%）。Logistic回归分析结果显示，中度夜间型患者CFSI、慢性疲劳的OR值（3.33，p =0.046）高于中度夜间型患者（2.07，p =0.004）。然而，SDS（1.67，p=0.028）和CFSI、活力下降（1.67，p=0.021）和抑郁感（2.02，p=0.001）中两个分量表的比值比（仅在中间型中发现显著相关性）在中度夜间型中高于中间型。这些结果表明，累积疲劳或抑郁状态和昼夜节律类型之间的关系存在于工人独立的工作时间，睡眠指数，或生活习惯。
This study clarified relationships between morningness-eveningness typology and cumulative fatigue or depressive state in Japanese male workers. 959 male chemical factory workers answered a questionnaire that included the MEQ, SDS, CFSI, age, marital status, sleep indexes, life habits, and labor load. Logistic regression analysis was performed with SDS and CFSI as objective variables. We obtained valid responses from 884 subjects, who were classified according to MEQ into definitely morning type (4.1%), moderately morning type (38.6%), intermediate type (55.1%), moderately evening type (2.3%), and definitely evening type (0%). The results of logistic regression analysis show that the odds ratio of a subscale among CFSI, chronic fatigue in the moderately evening type (3.33, p=0.046) was elevated compared with that in the intermediate type (2.07, p=0.004). However, the odds ratio of SDS (1.67, p=0.028) and two subscales among CFSI, decreased vitality (1.67, p=0.021), and depressive feelings (2.02, p=0.001), for which significant relationships were found only in the intermediate type, were higher in the moderately evening type than in the intermediate type. These results suggest that relationships between cumulative fatigue or depressive state and circadian typology exist among workers independent of working hours, sleep indexes, or life habits.
