Depression is a common mental disorder in older adults. This study aimed to determine the incidence of depression and the relationship between sedentary behavior and sleep duration in elderly individuals.
A total of 49,317 elderly adults from eight health centers in six Chinese provinces completed an online self-reported health questionnaire. Logistic regression was used to explore the association between sedentary behavior, sleep duration, and depression symptoms.
Symptoms of depression were present in 20.1% of older adults. Sedentary behaviors for >6 h/day (OR = 3.16; 95% CI: 2.90-3.44; p < 0.001) were a greater risk factor for depressive symptoms in older adults than sedentary behaviors for less than 3 h/day. Elderly individuals with short sleep durations (<7 h/day) were more likely to experience depression (OR = 2.20; 95% CI: 2.07-2.34; p < 0.001).
This study suggested that sedentary behavior and short sleep duration in older Chinese adults are associated with depressive symptoms. In China, further improvement of the mental health and lifestyle of elderly individuals may be warranted.
抑郁症是老年人常见的精神障碍。本研究旨在确定老年人中抑郁症的发病率以及久坐行为与睡眠时间之间的关系。
来自中国六个省的八个卫生中心的 49317 名老年人完成了在线自我报告健康问卷。使用逻辑回归探讨久坐行为、睡眠时间与抑郁症状之间的关联。
20.1%的老年人存在抑郁症状。与每天久坐行为<3 小时相比，每天久坐行为>6 小时（OR=3.16；95%CI：2.90-3.44；p<0.001）是老年人抑郁症状的更大危险因素。睡眠时间较短（<7 小时/天）的老年人更有可能出现抑郁（OR=2.20；95%CI：2.07-2.34；p<0.001）。
本研究表明，中国老年人的久坐行为和睡眠时间短与抑郁症状有关。在中国，可能需要进一步改善老年人的心理健康和生活方式。
