the objective of this study is to analyze the mediating role of loneliness, social isolation, and depressive symptoms in the relationship between multimorbidity and physical frailty among Chilean older adults living in the community, following the frailty model proposed by Gobbens.
A total of 2132 older people were studied through a cross-sectional analysis of data from a population-based survey, using hierarchical linear regression and mediations with Hayes' method. Variables of Gobbens' model guided the data analysis.
Regression analysis revealed significant associations between physical frailty and age, education, self-perceived economic status, physical activity, social relationships, mental health, and multimorbidity. Mediation analysis confirmed that loneliness, social isolation, and depressive symptoms are partial mediators in the relationship between multimorbidity and frailty.
Multimorbidity contributes significantly to physical frailty. Loneliness and social isolation show weaker associations with frailty, whereas depressive symptoms have a more substantial mediating role. These results underscore the need to integrate these factors into frailty interventions for older people.
本研究的目的是根据戈本斯提出的衰弱模型，分析孤独感、社会隔离和抑郁症状在智利社区老年人多种疾病与身体衰弱关系中的中介作用。
通过对一项基于人群调查的数据进行横断面分析，使用分层线性回归和海斯方法进行中介分析，对总共2132名老年人进行了研究。戈本斯模型的变量指导了数据分析。
回归分析显示身体衰弱与年龄、教育程度、自我感知的经济状况、身体活动、社会关系、心理健康和多种疾病之间存在显著关联。中介分析证实，孤独感、社会隔离和抑郁症状是多种疾病与衰弱关系中的部分中介因素。
多种疾病对身体衰弱有显著影响。孤独感和社会隔离与衰弱的关联较弱，而抑郁症状具有更重要的中介作用。这些结果强调了将这些因素纳入老年人衰弱干预措施的必要性。
