Higher walkability associated with increased physical activity and reduced obesity among United States adults

摘要: Objective This study examined associations among perceived neighborhood walkability, physical activity (PA), and obesity among United States adults. Methods Data 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. Results The sample included N = 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 …
