The National Center for Chronic Disease Prevention and Health Promotion at the Centers for Disease Control and Prevention funds a program to boost progress in reducing the prevalence and incidence of multiple chronic diseases and their associated risk factors. This article describes the program, State Public Health Actions to Prevent and Control Diabetes, Heart Disease, Obesity and Associated Risk Factors, and Promote School Health, and the program's action model, design, and administration and management structure. This program is based on 4 domains of public health action: 1) epidemiology and surveillance, 2) environmental approaches, 3) health care system interventions, and 4) community programs linked to clinical services. The 4 domains of public health action leverage data to inform action, support healthy choices and behaviors, strengthen delivery of clinical preventive services, and help Americans better manage their health.
