This study aimed to identify a correlation between insomnia and the occurrence of depression among Japanese hospital employees using the data obtained from a self-reported questionnaire.
A self-administered questionnaire on sleeping patterns, depression, fatigue, lifestyle-related diseases, and chronic pain was given to 7690 employees aged 20-60 years, and 5,083 employees responded.
An insomnia score of >2 was observed in 840 (13%) respondents. Chronic insomnia correlated significantly with gender, occupation, overtime work, metabolic syndrome, chronic pain, fatigue, and depression. Moreover, significant negative effects on depression scores were observed in males aged 30-39 (partial regression coefficient: b=0.357, p=0.016), females aged 20-29 (b=0.494, p<0.001), male administrative staff (b=0.475, p=0.003), males with metabolic syndrome (b=0.258, p=0.023), and both genders with chronic insomnia (male; b=0.480, p<0.001: female; b=0.485, p<0.001), and fatigue (male; b=1.180, p<0.001: female; b=1.151, p<0.001).
Insomnia is a risk factor for depression and for other lifestyle-related diseases. The insomnia score may be useful in preventative care settings because it is associated with a wide spectrum of diseases and serves as a valuable marker for early detection of depression. Thus, our future studies will focus on establishing a method for early detection of depression symptoms among workers across various job profiles.
本研究旨在利用自填式问卷调查所得数据，确定日本医院员工失眠与抑郁症发生之间的相关性。
对7690名年龄在20至60岁之间的员工进行了关于睡眠模式、抑郁、疲劳、生活方式相关疾病和慢性疼痛的自填式问卷调查，5083名员工进行了回复。
840名（13%）受访者的失眠得分>2。慢性失眠与性别、职业、加班、代谢综合征、慢性疼痛、疲劳和抑郁显著相关。此外，在30至39岁的男性（偏回归系数：b = 0.357，p = 0.016）、20至29岁的女性（b = 0.494，p < 0.001）、男性行政人员（b = 0.475，p = 0.003）、患有代谢综合征的男性（b = 0.258，p = 0.023）以及患有慢性失眠的男女（男性；b = 0.480，p < 0.001：女性；b = 0.485，p < 0.001）和疲劳（男性；b = 1.180，p < 0.001：女性；b = 1.151，p < 0.001）中，观察到对抑郁得分有显著负面影响。
失眠是抑郁症和其他生活方式相关疾病的危险因素。失眠得分在预防保健环境中可能有用，因为它与多种疾病相关，并且是早期发现抑郁症的有价值指标。因此，我们未来的研究将专注于建立一种在不同工作岗位的工人中早期发现抑郁症状的方法。
