Outline
To explore the mediating effect of activities of daily living (ADL) between arthritis and depression in the elderly, and to provide reference for preventing and intervening the occurrence and development of depression in the elderly.
Based on the 2018 China Health and Retirement Longitudinal Study (CHARLS) data, stepwise regression analysis and Bootstrap intermediary test were used to analyze the mediating effect of ADL between arthritis and depressive symptoms in the elderly.
The prevalence rate of arthritis was 8.12%, and the detection rate of depressive symptoms was 44.60%. Arthritis was positively correlated with ADL (r=0.025, P<0.05), arthritis was positively correlated with depression symptoms (r=0.036, P<0.01), and ADL was positively correlated with depression symptoms (r=0.348, P<0.001). ADL plays a mediating role in the relationship between arthritis and depressive symptoms. The mediating effect of ADL on depressive symptoms was 0.009,and the mediating effect accounted for 25.71% of the total effect.
Arthritis has a certain influence on the depressive symptoms of the elderly through ADL. Comprehensive intervention measures should be taken to improve the joint health of the elderly, reduce the prevalence of arthritis, and improve ADL of the elderly, to prevent the occurrence of depression in the elderly.
