Abstract
OBJECTIVE: To investigate the mediating role of depression in the association between multidimensional social deprivation and frailty among the elderly. METHODS: A total of 533 elderly individuals were enrolled from a district in Chengdu using a convenience sampling method. The participants responded to a questionnaire survey. Spearman rank correlation coefficient was employed to assess the correlations among social deprivation, depression, and frailty. MacKinnon's product-of-coefficients method was used to test the significance of the mediating effect of depression between social deprivation and frailty. RESULTS: Among the participants, the average score for social deprivation among the participants was 48.9±7.1, the depression detection rate was 12.8%, and the frailty incidence rate was 8.4%. Social deprivation was positively correlated with frailty (r=0.212, P<0.001) and depression (r=0.399, P<0.001), while depression was positively correlated with frailty (r=0.248, P<0.001). The results of the mediation analysis showed that depression partially mediated the relationship between social deprivation and frailty (P<0.05), accounting for 64.95% of the mediation effect. Specifically, depression partially mediated the relationship between socio-economic status, comprehensive feeling, and frailty (P<0.05), accounting for 70.30% and 64.76% of the mediating effect, respectively. Depression fully mediated the relationship between family and social support, political and social participation dimensions, and frailty (P<0.05). CONCLUSION: Social deprivation can influence frailty in elderly people, with depression partially mediating this association.
