Multilevel Modelling on the Prevalence and Determinants of Depressive Symptoms in Middle and Old-aged Rural-to-urban Immigrants in Chengdu

目的了解成都市中老年农转非居民抑郁症状流行水平及影响因素。方法采用多阶段分层整群抽样选取本市1 645名45岁及以上中老年农转非居民进行问卷调查。采用单因素分析比较不同特征的中老年农转非居民抑郁症状;采用多水平模型分析(家庭和个体)分析其抑郁症状的影响因素。结果成都市中老年农转非居民抑郁症状检出率为14.5%。采用卡方检验进行单因素分析,结果显示,不同性别、年龄、婚姻状况、慢性病患病情况、吸烟、饮酒、社会支持、家庭平均月收入、移居年限之间,其抑郁症状有所不同,差异具有统计学意义(P<0.05)。多水平模型结果显示,中老年农转非居民抑郁症状在家庭水平存在聚集性。家庭水平的经济条件和移居年限,个体水平的年龄、慢性病、吸烟、社会支持是影响其抑郁症状的主要因素。结论中老年农转非居民抑郁状况不容乐观,应积极采取针对性预防与干预措施,促进其心理健康发展。
