Abstract

Background

This study aimed to investigate the intrinsic and situational predictors of depression under the health ecological model.

Methods

Two waves (2011 and 2013) of survey data were collected from the CHARLS. A total of 5845 older adults (≧60) were included, and depression was defined as CESD-10 score ≧10. Random forest combined with interpretable methods were utilized to select important predictors of depression. Multilevel logit model was used to examine the associations of intrinsic and situational predictors with depression.

Results

After a 2-year follow up, 1822 individuals (31.17 %) developed depression. Interpretable analyses showed that both intrinsic and situational variables were predictive for depression. Multilevel logit model showed that age, gender, number of chronic diseases, number of pain areas, life satisfaction, and toilet distance were significantly associated with depression.

Conclusion

Both intrinsic and situational factors were found to be associated with depression among community older population, highlighting their significance for early prevention from the perspective of public health.

调查老年人抑郁症的内在和情景预测因素：对 CHARLS 数据库的分析。

研究背景本研究旨在探讨健康生态模型下抑郁症的内在和情景预测因素：从 CHARLS 收集了两波（2011 年和 2013 年）调查数据。共纳入5845名老年人（≧60岁），抑郁定义为CESD-10得分≧10。利用随机森林结合可解释的方法来选择抑郁症的重要预测因素。采用多层次逻辑模型检验内在和情境预测因素与抑郁的关联：经过两年的跟踪调查，有 1822 人（31.17%）患上了抑郁症。可解释性分析表明，内在变量和情境变量均可预测抑郁症。多层对数模型显示，年龄、性别、慢性病数量、疼痛部位数量、生活满意度和厕所距离与抑郁症有显著相关性：结论：研究发现，内在因素和情境因素都与社区老年人口中的抑郁症有关，这从公共卫生的角度强调了其早期预防的重要性。
