In the first study to look at the effect of neighborhood greenness on inner city children’s weight over time, researchers from the Indiana University School of Medicine and University of Washington report that higher neighborhood greenness is associated with slower increases in children’s body mass over a two year period, regardless of residential density. This study of over 3,800 inner city children revealed that living in areas with green space has a long term positive impact on children’s weight and thus health. The study appears in the December issue of the American Journal of Preventive Medicine.
