Chronic disease presents one of the greatest challenges to the public health of the American people. Research shows that almost one out of every two adults has at least one chronic disease. 7 out of 10 deaths among Americans are related to chronic illnesses. Our Nation's fiscal well-being is also impacted by chronic disease. Of the more than $2 trillion we spend on healthcare, 75 percent is accounted for by individuals with chronic conditions. In the workplace, these conditions account for nearly $1 trillion in lost productivity each year. A major gap exists between what we know about chronic disease prevention and what we're actually doing about it. There are many effective, evidence-based prevention programs. These proven approaches can prevent chronic diseases from developing in the first place, which will improve health and restrain healthcare costs.
