A015: Physical Activity and Social Well-Being in Older Adults

<bold>Objective:</bold> To explore the relationship between physical activity and social well-being in older adults and the mediating role of social support and self-aging attitudes. <bold>Methods:</bold> A physical activity rating scale, social support scale, self-aging attitude questionnaire, and social well-being scale were used to investigate 312 older adults, and structural equation modeling was constructed for analysis. <bold>Results:</bold> (1) Physical activity was significantly and positively correlated with social support (r=0.335, p &lt; 0.001) and social well-being (r=0.361, p &lt; 0.001); physical activity was significantly and negatively correlated with self-aging attitudes (r=-0.373, p &lt; 0.001); self-aging attitudes were significantly correlated with social support (r=-0.293, p &lt; 0.001) and social well-being (r=-0.113, p &lt; 0.05) were significantly negatively correlated; social support was significantly positively correlated with social well-being (r=.476, p &lt; 0.001). (2) Structural equation modeling analysis showed that social support and self-aging attitudes mediated the relationship between physical activity and social well-being, respectively, with indirect effect sizes (IEs) = 0.148 and -0.032; and social support and self-aging attitudes had a chain mediation between physical activity and social well-being among older adults, with an IE = -0.02. <bold>Conclusions:</bold> Physical activity among older adults not only directly affected social well-being, but also has a significant effect on social well-being through social support and self-aging attitudes. It also indirectly affected social well-being through the mediating role of social support and self-aging attitudes and the chain mediating role of social support-self-aging attitudes.
