Aim: Hearing loss and depression in older adults are associated with a lower social participation rate. However, few studies have thoroughly analyzed the relationship between them.
Methods: The data were obtained from the China Health and Retirement Longitudinal Study carried out in 2011, 2013 and 2015, and data from 24 306 participants ranging in age from 50 to 80 years were used in this study. Hearing loss, depression and social participation were assessed by self-reported hearing status, the 10-item Center for the Epidemiological Studies of Depression Short Form, and self-reported social participation activity types and frequency. The fixed effects logistic regression and random effects logistic regression were used to examine the relationship between hearing loss and social participation. The Sobel method was used to explore the relationship between hearing loss, depression and social participation.
Results: Compared with older adults without hearing loss, persons with hearing loss engaged in significantly fewer types of activities (β = -0.070, 95% CI -0.109, -0.031, P < 0.001) and at a lower frequency (β = -0.176, 95% CI -0.260, -0.093, P < 0.001). Depression significantly existed in the relationship between hearing loss and social participation as a mediating variable, and the percentage of indirect effects in this relationship were 16.5% and 20.8%.
Conclusions: The findings of this study suggest that when facing an aging society, improving the hearing status of older adults should be considered by policymakers. More efforts should be made to help older adults cope with depression. Geriatr Gerontol Int 2022; 22: 529-535.
