Programs that help people who have a family history or other risk factors associated with a chronic disease such as heart disease and stroke, cancer and diabetes make lifestyle or other changes that can prevent the disease or limit the initial onset. In addition to health promotion activities that encourage healthy living, prevention also embraces early detection efforts, including screening at-risk populations, as well as strong community-clinical linkages to help ensure that people at high risk of chronic diseases have access to community resources and support to prevent, delay or manage chronic conditions once they occur. Some programs may provide preventive care interventions for people who have a broader array of health concerns.
