Through a two-year grant from The JPB Foundation, the National Collaborative on Childhood Obesity Research (NCCOR) will strengthen its landmark Measures Registry by creating user guides for researchers. With more than 1,000 measures in the Measures Registry, the new guides will help users choose measures best suited for their research and evaluation work.
Given the high rates of obesity prevalence in the United States and around the world, research interest has grown regarding the effects of the community food and physical activity environments on individual diet and activity behavior. Robust measures of these environments are required in order to assess any effect. Measurement of food and physical environments is a relatively young field, although many “first generation” measures exist. Continue reading
