The Geographic Disparities in Transportation-Related Physical Activity in the United States: An Analysis of the 2017 NHTS Data

Chronic diseases such as cardiovascular disease and diabetes are the leading causes of death and disability in the United States. Outdoor physical exercises, such as walking and cycling, are effective and low-cost interventions for the prevention of chronic diseases. How much transportation-related physical activity does an average American get? Does where people live influence how much transportation-related physical activity they undertake? Why do people not exercise more? This study attempts to answer these questions by analyzing the 2017 National Household Travel Survey (NHTS). Study Methods This study uses the 2017 NHTS data to compare the number of walk and bike trips for people living in eight different geographic locations. Four locations are in large metropolitan areas (inner city, inner-ring suburb, mid-ring suburb, and outer-ring suburb), two are in small metropolitan areas (urban and rural parts), and the other two are in non-metropolitan areas (urban and rural parts). We conducted both descriptive and zeroinflated Poisson modeling analyses to evaluate the geographic patterns of general physical activity, walking, and cycling at the national scale, controlling for the characteristics of their neighborhood environment.
