If 10 percent of U.S. adults began walking regularly, we could avoid $5.6 billion in heart disease costs. Every $1 invested in a child safety seat saves $42 in prevented medical costs, and routine childhood immunization programs save 33,000 lives.

These are just a few examples featured in a new APHA video released today that shows how investments in public health and prevention programs can save lives and reduce costs.

The video is part of this year’s National Public Health Week observance: “Public Health is ROI: Save Lives, Save Money.” The theme underscores the important return on investments, or ROI, that public health delivers in protecting and improving the health of people every day.

“Public health is vital to our well-being, from the food we eat to the air we breathe, from our personal health to the effectiveness of our nation’s health system,” said Georges Benjamin, MD, executive director of APHA. “We hope this new video will help educate policy makers and the public about the important role public health plays in our lives every day and the significant value it delivers in saving lives, saving costs and improving quality of life over the long term.”

APHA’s video explains the real return on investment of public health efforts, from childhood to adulthood, from work to play and from school to on-the-go.
