Built environment policies and physical activity among U.S. adults: A regional analysis from 2006-2013
Methods: Individual-level data (N=158,842) were obtained from the National Health Interview Survey (NHIS) from 2006-2013. The sample consisted of white (n=95,078), black (n=26,422), and Hispanic (n=33,038) adults. Data on built environment policies (N=137) were obtained from the CDC’s Chronic Disease State Policy Tracking System and merged with NHIS data. Zero-inflated negative binomial regressions estimated the relationship between leisure-time moderate and vigorous physical activity and built environment policies, adjusting for potential confounders.
Results: The number of built environment policies enacted per year among U.S. Census regions ranged from 0 to 43, with a mean of 7. A significant (p<.0001) interaction between public health spending and built environment policies was detected. Built environment policies were associated (p. <.002) with increases in moderate and vigorous leisure-time physical activity for black, white, and Hispanic adults who live in the Western U.S. Built environment policies were positively associated (p<.001) with vigorous physical activity in white and black adults who live in the South, but had no association for Hispanic adults.
Conclusion: Policies designed to improve the built environment for physical activity may be more effective in some regions and for some racial/ethnic groups than others. Understanding the content of these policies may clarify why these policies vary in effectiveness.

Qualified on the content I am responsible for because: I am a PhD candidate whose dissertation examines the role of physical activity policies and their relationship with racial/ethnic health disparities in physical activity. My research interests and publications examine the role of policies and programs in addressing health behavior among different groups.
