Background: High rates of physical inactivity persist in the United States, with higher rates among non-Hispanic Black adults than among their White peers. However, a comparison of physical activity engagement across nativity among Black adults in the United States has yet to be fully documented. The purpose of this cross-sectional study was to examine physical activity engagement rates among African immigrant and Afro-Caribbean immigrant adults compared with native-born African American adults using data from the 2010 to 2018 National Health Interview Survey.
Methods: Using data from the 2010 to 2018 National Health Interview Survey, we used generalized linear models to compare levels of physical activity (meeting the moderate-to-vigorous physical activity [MVPA] recommendations) by ethnic subgroups of Black adults, sequentially adjusting for sociodemographic and health-related risk factors.
Results: Data from 38,037 adults (58.8% female, 21% college/graduate degree, and 41.4% with obesity) were included. Only 41.9% of all participants met the MVPA recommendations. In the fully adjusted models across the 9 years, higher levels of MVPA were seen among African Americans (42%) than among African immigrants (38%) and Afro-Caribbean immigrants (41%). Compared with African Americans, African immigrants were less likely to engage in physical activity that met the MVPA guidelines (prevalence ratio: 0.90; 95% confidence interval: 0.85, 0.96), whereas there were no differences in meeting the guidelines between Afro-Caribbean immigrants (prevalence ratio: 0.96; 95% confidence interval:0.90, 1.02) and African Americans.
Conclusion: Culturally tailored interventions addressing socioenvironmental barriers and facilitators of physical activity may have important impacts on physical activity promotion and long-term disease burden among Black adults across nativity.
