社交活跃度对老年人抑郁症状的影响

Effects of social activity on depressive symptoms in older adults

目的探究社交活跃度对老年人抑郁症状的影响。方法利用中国健康与养老追踪调查2018年数据,通过构建4个logistic回归模型控制老年人一般资料、健康状况、每日睡眠时长与日常生活能力,以及通过限制性立方样条分析6328名60岁及以上老年人社交活跃度对抑郁症状的影响。结果6328名老年人中,抑郁症状检出率为44.56%。控制混杂因素后,社交活跃度为老年人抑郁症状发生的保护因素(OR=0.952,95%CI:0.926~0.978);限制性立方样条模型显示,随着社交活跃度的增加,抑郁症状出现的风险持续降低(P<0.05)。结论老年人的抑郁症状受社交活跃度的影响,提高老年人的社交活跃度有利于预防抑郁症状的发生。

Objective To explore the influence of social activity on depression in Chinese older adults.Methods Using the data of 2018 China Health and Retirement Longitudinal Study(CHARLS), the effect of social activity on depression in 6 328 elderly people aged 60 years and older was analyzed by running 4 logistic regression models which sequentially controlled the general information, health status, length of sleep and activity of daily living of the elderly.Then restricted cubic spline was drawn based on the mo-dels.Results Among 6 328 older adults, the rate of having depressive symptoms was 44.56%.Social activity was a protective factor for depression in elderly people(OR=0.952,95%CI: 0.926-0.978) after controlling for the confounders.The restrictive cubic spline model showed a consistently decreasing risk of depressive onset with increased social activity(P<0.05).Conclusion Elderly depression is affected by social activity. Improving their social activity is beneficial to prevent the occurrence of depression.
