To know what programs, services, and policies are proven to protect and improve health, decision makers in communities, companies, nonprofit organizations, health systems, and at all levels of government can rely on recommendations from the Community Preventive Services Task Force (Task Force). The Task Force bases its recommendations on systematic reviews of the scientific evidence on community preventive services. Information on the 225 evidence-based reviews, findings, and recommendations are summarized in this document.  Task Force recommendations provide evidence-based options from which decision makers can choose what best meets their needs; they are not mandates for compliance or spending. They include programs, services, and policies that have proven effective in a variety of settings—such as worksites, schools, health plans, faith-based institutions, communities, and states—and can be used to effect changes.
