Physical Activity and Resilience among Middle-aged Japanese Adults

要旨

This study aimed to examine the relationship between physical activity, including lifestyle activities, exercise habits, and resilience in a sample of middle-aged Japanese adults (N=1,270; 604 men, 666 women; mean age=45.6 years, SD of age=8.5, age range=30-59 years). Considering the problems with previous methods of adjusting for confounding factors, this study used a propensity score to aggregate multiple covariates into a single variable and stratify on that single variable. Each group’s respondent data bias was adjusted by inverse probability weighted estimation using propensity scores, and the results confirmed the balance of covariates between the two groups of physical activity (without and with the physical activities) compared in this study. The weighted regression analysis results showed that among physical activities, both lifestyle activities and exercise habits were positively related to the innate and acquired factors of resilience. These results suggest that both lifestyle activities and exercise habits may be associated with both genetically innate and acquired factors of resilience.
