Background:
To examine demographic characteristics and physical activity (PA) behaviors of trail users on a newly constructed 2-mile urban rail/trail (ie, abandoned rail line converted to a recreational trail).
Methods:
A systematic evaluation process was initiated to monitor PA behaviors using the System for Observing Play and Recreation in Communities (SOPARC).
Results:
Slightly more males (n=2578, 54%) than females (n=2198, 46%) were observed using the rail/trail since its inception. A significant age group difference (F=16.68, P<.001) was observed among users with the vast majority being adults (n=3317, 69%). Women were 2.2 times more likely than men (95% CI 1.7-3.0) to be sedentary rather than vigorously active adjusted for age and race. Whites were 2.8 times more likely than nonwhites (95% CI 2.4-3.2) to engage in vigorous activity rather than walking, adjusted for age and gender. Rail/trail users resided on average 2.89 miles from the trail.
Discussion:
The most frequent users of the rail/trail were male, white adults, and observed PA varied for gender and age. More research is needed to better understand differences in patterns of trail use by various population groups.
