Gentrification and childhood obesity: Evidence from New York City public school students in public housing

Obesity (Silver Spring)Published Prospective cohort study

Authors' conclusion

With strong internal validity, this study shows that neighborhood gentrification differentially influenced children's health through obesity, based on borough of residence. Such findings could inform policies or interventions focused on subpopulations and geographies.
