Racial, Ethnic, and Nativity Disparities in Physical Activity and Sedentary Time among Cancer Prevention Study-3 Participants

Purpose Understanding racial/ethnic and nativity disparities in physical activity (PA) is important, as certain subgroups bear a disproportionate burden of physical inactivity–related diseases. This descriptive study compared mean leisure-time moderate-to-vigorous intensity physical activity (LTMVPA) by race/ethnicity and nativity. Methods The Cancer Prevention Study-3 (78.1% women; age, 47.9 ± 9.7 yr) includes 4722 (1.9%) Asian/Pacific Islander; 1232 (0.5%) Black/Indigenous (non-White) Latino; 16,041 (6.5%) White Latino; 9295 (3.8%) non-Latino Black; 2623 (1.1%) Indigenous American; and 210,504 (85.7%) non-Latino White participants across the United States and Puerto Rico. Participants completed validated LTMVPA and 24-h time use surveys at enrollment (2006–2013). Differences in LTMVPA across race/ethnicity and nativity were examined by ANCOVA with paired Tukey tests adjusting for age and sex. The proportion of time spent sitting, sleeping, and on PA by race/ethnicity was also compared. Results There were significant differences in LTMVPA by race/ethnicity (race main effect, P
