Traffic-related environmental factors and childhood obesity: A systematic review and meta-analysis.

ABSTRACT: A growing body of research links traffic-related environmental factors to childhood obesity; however, the evidence is still inconclusive. This review aims to fill this important research gap by systematically reviewing existing research on the relationship between traffic-related environmental factors and childhood obesity.
