Depression is the most frequent psychiatric disorder among the older adults, the purpose of this study is to explore the mediation effect of health promoting lifestyle on the relationship between Socioeconomic Status (SES) and depression, so as to provide practical reference for effectively preventing and alleviating depression of the older adults.
A multi-stage random sampling method was conducted in Shanxi Province. A total 8526 older adults were included in the analysis. Regression analysis was used to explore the relationship between the socioeconomic status, health promoting lifestyle and depression, and the mediation effect test process was used to verify the mediating mechanism of health promoting lifestyle on this relationship.
62.1% of the older adults had depression symptoms in this study, and there were significant differences in depression scores among the older adults with gender, age, residence, marital status, endowment pattern, self-care ability, exercise frequency, physical examination frequency, daily diet rules(P<0.05). The results of mediating effect analysis showed that health promoting lifestyle as mediation effect between social economic status and depression was established, and the mediating effect was accounted for (a*b/c) 63.1%.
Given the cross-sectional study, it is not possible to make causal inferences.
There were different degrees of depression in the older adults. The lower the SES is, the higher the risk of depression is. This result once again confirms the social causation theory. Combined with the theory of health risk behavior, the study further confirmed the applicability of lifestyle mechanism in the intermediate mechanism of the relationship between SES and depression in the elderly. Thus, in addition to providing material support and financial assistance, helping the elderly develop a healthy lifestyle is also effective measure to improve their depression.
抑郁症是老年人中最常见的精神障碍，本研究旨在探讨健康促进生活方式在社会经济地位（SES）与抑郁之间的关系中的中介作用，为有效预防和缓解老年人的抑郁提供实践参考。
在山西省采用多阶段随机抽样方法，共纳入 8526 名老年人进行分析。采用回归分析探讨社会经济地位、健康促进生活方式与抑郁之间的关系，并采用中介效应检验过程验证健康促进生活方式对这种关系的中介机制。
本研究中 62.1%的老年人有抑郁症状，且不同性别、年龄、居住地、婚姻状况、养老金模式、自理能力、运动频率、体检频率、日常饮食规律的老年人抑郁得分存在差异（P<0.05）。中介效应分析结果表明，健康促进生活方式作为社会经济地位和抑郁之间的中介效应成立，中介效应占比为（a*b/c）63.1%。
鉴于这是一项横断面研究，因此无法做出因果推断。
老年人存在不同程度的抑郁，社会经济地位越低，患抑郁症的风险越高。这一结果再次证实了社会因果理论。结合健康风险行为理论，本研究进一步证实了生活方式机制在老年人 SES 与抑郁关系的中介机制中的适用性。因此，除了提供物质支持和经济援助外，帮助老年人养成健康的生活方式也是改善他们抑郁状况的有效措施。
