Nutrition & Physical Activity Policy Research Projects


The CHildhood Obesity Intervention Cost-Effectiveness Study (CHOICES) assesses the comparative-effectiveness and cost-effectiveness of approximately 40 interventions aimed at reducing childhood obesity, including policy changes and interventions that have been identified as being effective, promising or prevalent.

Past Nutrition & Physical Activity Policy Research Projects

This project consisted of monitoring and evaluation activities that critically examined actual and hypothetical policy and environmental interventions designed to halt and eventually reverse the childhood obesity epidemic in the U.S. It included the application of mathematical and statistical models to understand and forecast the future of the obesity epidemic, including our “energy gap” model, trend prediction models, and microsimulation model for energy balance in growth.

The Assessing Cost Effectiveness (ACE) Obesity America project was a collaboration between the HPRC, Columbia University, and Deakin University in Australia to identify cost-effective options for childhood obesity interventions. It built upon the work of our Australian partners, who used the best available evidence to calculate health impacts in terms of body mass index and disability-adjusted life years saved.

This project documents economic investment in communities through the federal Safe Routes to School (SRTS) program and examines the distribution of funds across diverse areas. We developed measures of successful SRTS economic investment and project implementation in low-resource communities based on stated objectives of the SRTS program. The project aimed to inform policies to support equitable, comprehensive SRTS programs and safe, active environments for youth.

Nutrition & Physical Activity Policy Research Networks


The Nutrition and Obesity Policy Research and Evaluation Network (NOPREN) is a thematic research network of the CDC’s Prevention Research Center Program. Its mission is to conduct transdisciplinary nutrition- and obesity-related policy research and evaluation. The work of NOPREN members help to foster understanding of the effectiveness of policies related to preventing childhood obesity through improved access to affordable, healthy foods and beverages in a variety of settings, such as communities, worksites, and schools.

Physical Activity Policy Research Network (PAPRN) is a thematic research network of the CDC’s Prevention Research Center Program. Its mission is to conduct transdisciplinary policy research that addresses the determinants, dissemination, implementation, and outcomes of physical activity-related policies. As a collaborating center, the HPRC works with PAPRN and the CDC to develop resources to educate local and state policymakers on translating and disseminating physical activity policy research.

The mission of the Massachusetts Cancer Prevention Community Research Network (MCPCRN) was to foster collaborative research among community organizations and public health researchers. It focused on addressing disparities in cancer risk due to socioeconomic status and race/ethnicity by working with a range of community organizations.

The Collaborative Obesity Modeling Network (COMnet) was a project to connect leading childhood obesity modelers. Groups used a variety of statistical models to study trends in obesity and the impact of various causes of the epidemic in multiple countries. The team from Harvard and Columbia Universities focused on modeling changes in obesity rates in the U.S. and estimated the “energy gap” responsible for changes in weight distribution among children and teens.
