Does Acculturation Influence Physical Activity in Japanese American Older Adults?

PURPOSE: Despite the health benefits of physical activity, demographic and health factors as well as cultural backgrounds are thought to influence participation in physical activity. The aim of this study is to examine whether acculturation is associated with physical activity in a sample of Japanese American older adults living on the continental United States. METHODS: A survey was mailed to Japanese Americans identified from the mailing list of two community­based organizations. The survey included questions on physical activity, acculturation, demographics, health behaviors, and self­reported health status. Data were analyzed using bivariate and multiple regression techniques. FINDINGS: Acculturation was not a significant predictor of phsical activity in either community sample, or the pooled sample, after conrolling for other sociodemographic andhealth status variables. The models explained 23% to 2% of the variance in physical activity. Statistically significant predictors of physical activity included gender, work status, age, income, and health status. CONCLUSIONS: Our findings differ from studies of Japanese Americans in Hawaii and other racial/ethnic groups, suggesting that accultraion may have differential effects depending on the environment and the racial/ethnic group under study.
