Objectives: This study examined the relationship between acculturation and leisure-time physical inactivity among Mexican American adults.
Methods: Using data from the Third National Health and Nutrition Examination Survey, we estimated the prevalence of physical inactivity according to place of birth and language used at home.
Results: Spanish-speaking Mexican Americans had a higher prevalence of physical inactivity during leisure time than those who spoke mostly English, independent of place of birth.
Conclusions: Acculturation seems to be positively associated with participation in leisure-time physical activity.
