Sleep, fish consumption, and depression have a close relationship; however, the role of sex differences in sleep, fish consumption, and depression research is not yet well-established. This study aimed to examine whether the impact of bedtime, sleep-onset latency, sleep duration, sleep quality, and fish consumption on depressive symptoms differed in women and men. An online survey was conducted in South Korea with a stratified random sample of 600 participants between the ages of 20 and 69, whose gender and age were proportional to estimates of Korea's general population. The 20-item Center for Epidemiologic Studies Depression Scale was used to measure depressive symptoms with a cut-off score of 16. The Pittsburgh Sleep Quality Index (PSQI) was applied to evaluate sleep timing, sleep-onset latency, sleep duration, and sleep quality. Our results indicated that late bedtime and short sleep duration were independently associated with depressive symptoms in women. Sleep-onset latency and poor sleep quality were independently associated with increased prevalence of depressive symptoms in both men and women. Higher fish consumption was significantly associated with decreased prevalence of depressive symptoms in men only. Our findings suggested the importance of a different approach for men and women in terms of promoting healthy sleep habits. In addition, higher fish consumption may be beneficial in the primary prevention of depression in Korean men. Further research is needed to confirm the findings from this cross-sectional study.
睡眠、鱼类消费与抑郁症之间存在密切关系；然而，性别差异在睡眠、鱼类消费和抑郁症研究中的作用尚未得到充分确立。本研究旨在探讨就寝时间、入睡潜伏期、睡眠时间、睡眠质量和鱼类消费对抑郁症状的影响在男性和女性中是否存在差异。在韩国进行了一项在线调查，对600名年龄在20至69岁之间的参与者进行分层随机抽样，其性别和年龄与韩国总人口的估计比例相称。使用20项流行病学研究中心抑郁量表来测量抑郁症状，临界值为16。匹兹堡睡眠质量指数（PSQI）用于评估睡眠时间、入睡潜伏期、睡眠时间和睡眠质量。我们的结果表明，就寝时间晚和睡眠时间短与女性的抑郁症状独立相关。入睡潜伏期和睡眠质量差与男性和女性抑郁症状患病率的增加独立相关。仅在男性中，较高的鱼类消费量与抑郁症状患病率的降低显著相关。我们的研究结果表明，在促进健康睡眠习惯方面，针对男性和女性采取不同的方法很重要。此外，较高的鱼类消费量可能有助于韩国男性抑郁症的一级预防。需要进一步的研究来证实这项横断面研究的结果。
