The Office of Disease Prevention and Health Promotion (THI) encourages all Americans to lead healthy and active lives. We accomplish this by establishing and promoting national public health priorities, translating science into policy, guidance, and tools, and working to improve health literacy and equitable access to clear and actionable health information. 

Congress created THI in 1976 to lead disease prevention and health promotion efforts in the United States. We’re part of the U.S. Department of Health and Human Services under the Office of the Assistant Secretary for Health.

THI is responsible for coordinating The Health Initiatives and its microsites — which are funded by the U.S. government. 

Our Work

We set priorities for improving the nation’s health, provide science-based nutrition and physical activity guidance, and create tools and resources to help people make healthy choices.
