GPS-BASED ACTIVITY SPACE EXPOSURE TO GREENNESS AND WALKABILITY IS ASSOCIATED WITH INCREASED ACCELEROMETER-BASED PHYSICAL ACTIVITY

GPS-based activity space exposure to greenness and walkability is associated with increased accelerometer-based physical activity

Introduction: Built and natural environments may provide opportunities for physical activity.However, studies are limited by primarily using residential addresses to define exposure and self-report to measure physical activity.We quantified associations between global positioning systems (GPS)-based activity space measures of environmental exposure
