摘　　要：目的分析我国中老年人睡眠时长和肌力对抑郁症状的影响,为促进中老年人心理健康提供参考。方法本研究纳入了中国健康与养老追踪调查数据库中同时参与2011年和2018年调查的4225名中老年人。通过问卷调查其睡眠时长和抑郁症状,并检测其肌力(握力和五次起坐时间)。采用多因素Cox回归模型探讨睡眠时长和肌力对抑郁症状的联合作用。结果调查对象中,1465(34.67%)名中老年人在2018年新发抑郁症状。非适宜睡眠时长(>9 h/d或<7 h/d)、低握力和五次起坐时间长的中老年人抑郁症风险显著增加。与适宜睡眠时长(7~9 h/d)和高肌力(高握力和短五次起坐时间)组相比,非适宜睡眠时长/低肌力(低握力和五次起坐时间长)组调查对象发生抑郁症状的风险上升(HR=1.99,95%CI:1.38~2.87)。结论非适宜睡眠时长和低肌力是中老年人抑郁症状的重要危险因素。因此,应积极指导老年人适度进行肌肉力量增强训练,并引导其养成良好的睡眠习惯以促进其心理健康水平。Objective To investigate the combined effects of sleep duration and muscle strength on depressive symptoms in Chinese middle-aged and elderly adults,and to provide reference for mental health promotion.Methods A total of 4225 participants from the China Health and Retirement Longitudinal Survey(CHARLS)who participated in both 2011 and 2018 waves.Sleep duration and depressive symptoms were assessed using a questionnaire,and muscle strength(grip strength and chair-rising time)was measured.Multivariable adjusted cox regression models were used to explore the combined effects of sleep duration and muscle strength on depressive symptoms.Results In total 1465(34.67%)participants reported depressive symptoms in 2018.After adjusting for confounding factors,participants with non-recommended sleep duration(>9 h/d or<7 h/d),lower grip strength,and longer chair-rising time had significantly increased risk of depressive symptoms.Compared with those with recommended sleep duration(7 to 9 h/d)and high muscle strength(high grip strength and short chair-rising time)group,individuals with non-recommended sleep duration and low muscle strength showed significantly increased risk of depressive symptoms(HR=1.99,95%CI:1.38-2.87).Conclusion Non-recommended sleep duration and low muscle strength are significant risk factors for depressive symptoms.Thus,increasing muscle strength and improving sleep duration should be recommended for mental health promotion in middle-aged and elderly people.
