Stopping the obesity epidemic with cost-effective interventions

The Childhood Obesity Intervention Cost-Effectiveness Study (CHOICES) at the Harvard T.H. Chan School of Public Health is working to help reverse the U.S. obesity epidemic by identifying the most cost-effective childhood obesity interventions.

Adults and children in the U.S. consume more calories from foods and beverages than they are expending. Over the past few decades, this trend has created an obesity epidemic.

Identifying what works to prevent childhood obesity has become a priority for public health researchers, policymakers, and the general public.

Little attention has been paid, however, to identifying solutions that not only work, but that deliver the best results for the dollars invested in them. Some interventions can even produce cost savings. CHOICES is focused on identifying these cost-effective interventions.


Rigorous process, unique focus

The CHOICES research team has generated cost-effectiveness estimates for more than 40 of the most widely promoted or implemented childhood obesity prevention interventions, many of which have never been fully evaluated for comparative- or cost-effectiveness.

We know what works

Our research identifies cost-effective childhood obesity intervention strategies within five sectors:

  • School
  • Community & government
  • Early & out-of-school care

  • Transportation
