Association Between Built Environment or Health Behavior and Good Health Status Using ACSM American Fitness Index® Data Between 2018 and 2022

Abstract

The US cities still have room for improvement in residents’ health and there are significant differences in general health measures between the cities. High quality environment assets and personal healthier behaviors of residents were known as factors related to better health. Because both sufficient sleep and higher level of personal physical activity are well-known indicators to attain optimal health of individuals, city-level measures of resident health behaviors, such as sleep quantity, and environmental assets that support physical activity may jointly improve residents’ general health. Further, sufficient sleep may mediate the effect of activity-related environmental factors on general health. However, evidence regarding such associations at the city level is lacking. The American College of Sports Medicine (ACSM) American Fitness Index® (AFI) data currently provide both environment assets and health indicators for the 100 largest US cities. The aim of this research was to test the following three hypotheses using the 2018 to 2022 AFI data. First, the association between environment indicators of cities and good health status of residents was examined. Second, the association between personal health behaviors of residents and good health status was also examined. Lastly, the moderating or mediating effect of sleep on the association between significant environmental factors and good health status was examined. This study discovered that activity-related environment factors, such as availability of parks within a 10-minute walk, Walk Score®, Bike Score®, and adoption of Complete Streets policy, were significantly associated with the self-reported general health status of residents. This study also demonstrated all measured healthy behaviors including meeting physical activity guidelines, using active transport to work, sufficient intake of fruits and vegetables, sufficient sleep, and non-smoking were positively related to general health status of city residents. This study also identified the synergistic interaction between sufficient daily sleeping and environment factors related to the level of physical activity on residents’ good health status. Overall, these findings will provide evidence for better understanding the health-related unmet needs of residents in US cities, and also create valuable context and support for development and targeting of more efficacious public health interventions and messaging.
