To investigate the association between social support and depressive symptoms among internal migrant workers with a focus on the mediating role of a healthy lifestyle.
Cross-sectional study.
The research was conducted among internal migrant workers in Henan Province, China, in August 2023.
Internal migrant workers are defined as individuals residing outside their registered household location (excluding mobility within the municipal district) and participating in various social and economic activities, including employment, entrepreneurship and social services.
Social support was measured using the Chinese version of the social support rating scale. The severity of depression among the study participants was evaluated using the Patient Health Questionnaire-9. A healthy lifestyle was assessed based on the questionnaire we developed based on the American Medical Association Healthy Lifestyle Scale. Statistical analyses, including logistic regression, Spearman's correlation and mediation analysis, were deployed to explore the associations between social support, healthy lifestyle and depressive symptoms.
Among 19 326 participants, 21.45% exhibited depressive symptoms, with a higher prevalence observed among males. Social support levels among internal migrant workers were found to be lower than those in the general population, and higher social support was significantly associated with a decreased risk of depressive symptoms (OR=0.102, 95% CI: 0.086 to 0.121). Mediation analysis revealed that a healthy lifestyle partially mediated the relationship between social support and depressive symptoms among internal migrant workers, with a mediation effect of -0.063, accounting for 18.75% of the total effect.
This study provides insights into the complex interplay between social support, healthy lifestyle and depressive symptoms among internal migrant workers in China. Implementing interventions aimed at enhancing social support and promoting healthy lifestyle behaviours can significantly improve the mental health and overall well-being of internal migrant workers.
探讨社会支持与外出务工人员抑郁症状之间的关联，重点关注健康生活方式的中介作用。
横断面研究。
2023年8月在中国河南省的外出务工人员中开展此项研究。
外出务工人员定义为居住在其户籍所在地以外（不包括市区内的流动）并参与各种社会经济活动（包括就业、创业和社会服务）的个人。
采用中文版社会支持评定量表测量社会支持。使用患者健康问卷9评估研究参与者的抑郁严重程度。基于我们根据美国医学协会健康生活方式量表编制的问卷评估健康生活方式。采用包括逻辑回归、Spearman相关性分析和中介分析在内的统计分析方法，探讨社会支持、健康生活方式与抑郁症状之间的关联。
在19326名参与者中，21.45%表现出抑郁症状，男性患病率更高。发现外出务工人员的社会支持水平低于一般人群，较高的社会支持与抑郁症状风险降低显著相关（OR=0.102，95%CI：0.086至0.121）。中介分析显示，健康生活方式在外出务工人员的社会支持与抑郁症状之间起部分中介作用，中介效应为-0.063，占总效应的18.75%。
本研究深入探讨了中国外出务工人员社会支持、健康生活方式与抑郁症状之间的复杂相互作用。实施旨在增强社会支持和促进健康生活方式行为的干预措施，可显著改善外出务工人员的心理健康和整体幸福感。
