基于倾向性评分匹配法的慢性病共病对我国中老年人抑郁症状的影响研究

Research on Influence of Chronic Disease Comorbidity on Depressive Symptom Among Middle-aged and Elderly People in China Based on Propensity Score Matching

目的:探讨慢性病共病对我国中老年人抑郁症状的影响,为有效防控中老年人抑郁症状的发生,改善中老年人慢性病共病患者的心理健康提供参考。方法:利用2018年中国健康与养老追踪调查数据,选取16587名45岁及以上中老年人为研究对象。采用倾向性评分匹配法匹配慢性病共病与非共病中老年人,采用单因素分析和多因素logistic回归分析研究共病对中老年人抑郁症状的影响。结果:我国中老年人慢性病共病患病率为55.88%,慢性病共病中老年人中抑郁症状发生率为45.65%。Logistic回归分析结果显示慢性病共病是中老年人发生抑郁症状的危险因素(P<0.001);此外,社会人口学特征、社会经济特征、健康状况、社会支持、行为生活方式也是中老年人发生抑郁症状的影响因素(P<0.05)。结论:与非慢性病共病中老年人相比,慢性病共病中老年人出现抑郁症状的风险更高,应重视对慢性病共病中老年人群心理健康的管理。

Objective:To investigate the influence of chronic disease comorbidity on depressive symptom among middle-aged and elderly people in China,so as to provide references for effectively preventing and controlling the occurrence of depressive symptom of middle-aged and elderly people and improving the mental health of middle-aged and elderly patients with chronic disease comorbidity.Methods:Based on the China health and retirement longitudinal survey data in 2018,16587 middle-aged and elderly people aged 45 and above were selected as the subjects.The propensity score matching was used for matching chronic disease comorbidity and non-comorbidity among middle-aged and elderly people.The influence of comorbidity on depressive symptom among middle-aged and elderly people was analyzed by univariate analysis and multivariate logistic regression analysis.Results:The prevalence rate of chronic disease comorbidity among middle-aged and elderly people was 55.88%and the incidence rate of depressive symptom among middle-aged and elderly people with chronic disease comorbidity was 45.65%.Logistic regression analysis showed that the chronic disease comorbidity was the risk factor of depressive symptom among middle-aged and elderly people(P<0.001).Besides that,the demographic characteristics,socio-economic characteristics,health condition,social support and lifestyles were also related to the depressive symptom among middle-aged and elderly people(P<0.05).Conclusion:Compared with the middle-aged and elderly people without chronic disease comorbidity,the risk of depressive symptom affected by chronic disease comorbidity among middle-aged and elderly people is higher,and more attention should be paid on the mental health management among middle-aged and elderly people with chronic disease comorbidity.
