Community-based approaches to preventing chronic diseases are attractive because of their broad reach and low costs, and as such, are integral components of health care reform efforts.

In response to the illness and death caused by preventable chronic diseases, the US Department of Health and Human Services created Communities Putting Prevention to Work to support community efforts in tackling tobacco use and obesity through policy, systems, and environmental change.

Most tobacco and obesity-related matched objectives were successfully accomplished by communities. Public–private partnerships should be considered when addressing chronic disease prevention.
