Abstract P284: Exploring Differences in Self-Reported Moderate and Vigorous Physical Activity Among Hispanic Subgroups, Non-Hispanic Black, and Non-Hispanic White: National Health Interview Survey (NHIS), 1997-2012

Background: Epidemiologic studies to date have typically categorized all Hispanic subgroups into one group. To better understand moderate and physical activity trends among subgroups of Hispanic adults in the US, we assessed self-reported physical activity by race/ethnicity over 15 years (1997-2012) NHIS. Methods: Data from 452,845 Mexican/Mexican American, Puerto Rican, Cuban/Cuban American, Other Hispanic, non-Hispanic Black, and non-Hispanic White participants over the age of 18 years were used. Annual age-adjusted moderate physical activity and vigorous physical activity prevalence were estimated by race/ethnicity and analyses of trends in average annual age-adjusted physical activity prevalence were conducted by education and race/ethnicity. Results: Out of the 452,845 individuals included in this analysis, 48.7% were male, with an overall mean age of 45.9 years for both men and women. Fifty-four percent of the total population had greater than a high school education. There were statistically significant differences for all demographic variables by gender and by race/ethnicity (P Conclusions: These results suggest that further consideration should be given to subgroup analyses in studies of Hispanics, particularly as they pertain to self-reported levels of physical activity.
