ObjectiveThis study examined associations among perceived neighborhood walkability, physical activity (PA), and obesity among United States adults.MethodsData from the 2020 National Health Interview Survey were analyzed. Walkability was assessed using a summative scale and was categorized as low, medium, or high. PA was categorized as insufficient (0‐149 min/wk) or sufficient (150+ min/wk). Multivariable regressions estimated an association between obesity and BMI and PA/walkability. Mediation analysis was used to partition contribution of PA as a mediator. Effect modification by race and ethnicity in the association between walkability and BMI was explored.ResultsThe sample includedN= 31,568 adults. Compared with those in low‐walkability neighborhoods, participants in high‐walkability neighborhoods had increased odds of sufficient PA (odds ratio [OR] = 1.48; 95% CI: 1.30‐1.69) and decreased obesity odds (OR = 0.76; 95% CI: 0.66‐0.87). PA partially mediated the association between walkability and BMI (23.4%; 95% CI: 14.6%‐62.7%). The association between walkability and BMI was modified by race and ethnicity (F[5,567]= 2.75;p= 0.018). Among White, Black, Hispanic, and Asian adults, BMI decreased with increasing walkability; among American Indian/Alaska Native and multiracial/other adults, BMI increased with increasing walkability.ConclusionsThe findings highlight the importance of investing in the built environment to improve perceptions of walkability and promote PA and healthy weight, as well as developing interventions to target racial and ethnic disparities in these outcomes.
