This study was conducted to determine if specific factors (physical activity self-efficacy, sense of community, social support, perceived physical and mental health, and neighborhood environment and facilities) predicted physical activity among 258 older Thais living in six registered, low-socioeconomic, urban communities across metropolitan Bangkok. The theoretical model was based on integrated concepts from Pender’s Health Promotion Model and the Social Ecological Model. The hypothesized model was tested using path analysis.

The final model explained 33%, 51% and 22% of the variance in physical activity, physical activity self-efficacy and sense of community, respectively. Physical activity self-efficacy was the most powerful predictor in explaining physical activity. Sense of community and perceived physical health had a positive direct effect and a positive indirect effect, through physical activity self-efficacy, on physical activity. Perceived mental health had a negative indirect effect on physical activity, through physical activity self-efficacy, but a positive direct effect on physical activity. Social support, as well as neighborhood environment and facilities, did not significantly predict physical activity. However, social support had a positive indirect effect on physical activity through sense of community. Neighborhood environment and facilities had a positive indirect effect on physical activity through sense of community and physical activity self- efficacy.

These findings provide a greater understanding of factors that predict physical activity among older Thais living in low-socioeconomic urban communities across metropolitan Bangkok. The results may be useful in the development of effective interventions and/or guidelines for promoting physical activity for older Thais.
