Outline
To explore the mediating pathway mechanisms of depression and life satisfaction in the effects of social activities on quality of life in older adults and to inform the enhancement of quality of life in older adults and the achievement of healthy aging.
A stratified whole group sampling method was used to select 893 older adults aged 60 years and above in Kunming and Xuanwei, Yunnan Province. A face-to-face questionnaire survey was conducted, which included general demographic characteristics, frequency of social activities, life satisfaction, Patient Health Questionnaire (PHQ-9), and EuroQoL Five Dimension Questionnaire (EQ-5D-5L). Univariate and Spearman correlation analyses were performed using SPSS, and Tobit regression (stata) and Structural Equation Model (AMOS) were used to analyze the effects of social activities, depression, and life satisfaction on quality of life as well as to test for the chain mediation effect.
The health utility values of quality of life in the elderly ranged from -0.208 to 1.000, and Spearman correlation analysis showed that the quality of life in the elderly was positively correlated with social activities and life satisfaction (rs=0.07, 0.32, P<0.05); the quality of life was negatively correlated with the condition of depression (rs=-0.53, P<0.05); the chain mediation effect analysis showed that depression produced independent mediation effect between social activities and the quality of life of the elderly, with an effect coefficient of 0.029 (95%CI: 0.013-0.050); and depression and life satisfaction had a chain mediation effect between social activities and quality of life with an effect coefficient of 0.003 (95%CI: 0.001-0.006).
Active participation in social activities in older adults can reduce their depressive symptoms, thereby increasing their life satisfaction and consequently improving their quality of life.
