Depression is a common mental health disorder. Despite sleep disturbance being associated with depression, limited data regarding the association of sleep quality with depression exists. We aimed to investigate the association between sleep quality and depressive symptoms in the South Korean population.
This cross-sectional study used data from the 2018 Korean Community Health Survey, a nationwide representative survey conducted annually at national public health centers since 2008. The study population comprised 176,794 individuals (78,356 male and 98,438 female) aged 19 years and over. Sleep quality was measured using the Korean version of Pittsburgh Sleep Quality Index and depressive symptoms with the Patient Health Questionnaire-9. Data were analyzed using multiple logistic regression.
The average PSQI score was 5.03 for men and 5.98 for women. Individuals of both sexes with poor sleep quality were more likely to be depressed (men: odds ratio (OR) = 7.02 [95% confidence interval (CI) = 6.17-7.99]). In subgroup analysis stratified by independent variables, participants with the following characteristics had greater association between poor sleep quality and depressive symptoms: unmarried, college or higher education, white-collar occupation, current smoker, frequent drinker, walking physical activity, and no-stress.
Limitations included the cross-sectional nature of the study, use of only secondary data and a self-rated questionnaire for evaluating depressive symptoms, and inherent limitations in the PSQI.
Poor sleep quality may contribute to depressive symptoms among Korean adults. Screening for poor sleep quality and implementing measures to improve sleep behaviors may prevent the onset of depression.
抑郁症是一种常见的心理健康障碍。尽管睡眠障碍与抑郁症有关，但关于睡眠质量与抑郁症之间的关联的数据有限。我们旨在调查韩国人群中睡眠质量与抑郁症状之间的关系。
本横断面研究使用了 2018 年韩国社区健康调查的数据，该调查自 2008 年以来每年在国家公共卫生中心进行，是一项全国代表性调查。研究人群包括 176794 名 19 岁及以上的个体（男性 78356 人，女性 98438 人）。睡眠质量使用韩国版匹兹堡睡眠质量指数进行测量，抑郁症状使用患者健康问卷-9 进行测量。使用多因素逻辑回归进行数据分析。
男性的平均 PSQI 得分为 5.03，女性为 5.98。睡眠质量差的男女个体更有可能抑郁（男性：比值比（OR）=7.02[95%置信区间（CI）=6.17-7.99]）。在按自变量分层的亚组分析中，具有以下特征的参与者睡眠质量差与抑郁症状之间的关联更大：未婚、大学或以上学历、白领职业、当前吸烟者、经常饮酒者、步行体育活动和无压力。
研究的局限性包括研究的横断面性质、仅使用二次数据和自我评估问卷评估抑郁症状以及 PSQI 的固有局限性。
睡眠质量差可能导致韩国成年人出现抑郁症状。筛查睡眠质量差并采取措施改善睡眠行为可能有助于预防抑郁症的发生。
