This study examines environmental, transportation, social, and time barriers to physical activity.
Survey questions from the nationally representative Greenstyles survey (N = 2181) were summed to create environmental, transportation, social, and time barrier variables. Logistic regression was used to determine if the barrier variables had a significant association with physical activity levels.
Those who have low barriers to physical activity are more likely to meet the recommended physical activity levels compared with those with medium and high barriers. In addition, transportation, social capital, and time barriers independently contributed to the low levels of physical activity.
Removal of multiple barriers to physical activity may have an additive effect of increasing physical activity levels in Americans. Promoting physical activity requires strategies and research across multiple sectors to mitigate these barriers.
