Background: This study examined the relationships between components of the home environment and physical activity (PA) behaviors among African American adolescents. Methods: A community-based sample of 99 African American parent-child dyads (62% girls; 42% overweight/obese, 15.0 ± 0.2 years) were included in this analysis. The home environment (PA equipment, family support for PA, and internet access) was evaluated using the Health and Environment Survey. Child PA was measured objectively using accelerometry. Data collection occurred between 2014 and 2016. Results: Internet access was associated with 29 fewer minutes of light physical activity [p = 0.011, β =-29.25 ± 11.28 (95% confidence interval:-51.65 to-6.86)], 9 fewer minutes of moderate-To-vigorous physical activity [p = 0.045, β =-9.10 ± 4.48 (-17.98 to-0.21)], and 38 fewer minutes of total PA (TPA) [p = 0.006, β =-38.35 ± 13.38 (-65.62 to-11.08)]. Family support was associated with 2 minutes of TPA [p = 0.044, β = 2.25 ± 1.10 (-1.97 to 3.19)]. PA equipment was not significantly associated with greater PA (all p's > 0.05). Conclusions: These findings suggest that home internet access may hinder participation in PA among African American adolescents. Future research should continue to identify barriers in the home environment that contribute to physical inactivity among African American adolescents.
