Understanding the determinants of active transportation to school among children: evidence of environmental injustice from the Quebec Longitudinal Study of Child Development.

Purpose: To examine the combined influence of poverty and dangerousness of the neighborhood on active transportation (AT) to school among a cohort of children followed throughout the early school years.

Methods: Growth curve modeling was used to identify determinants of AT to school among 710 children participating in the Quebec Longitudinal Study of Child Development from 2003 through 2006. Parent-reported dangerousness and pedestrian-vehicle collision data were merged with travel mode and health data.
