Defining the Problem, Preventing Chronic Diseases, Improving the Public’s Health

CDC’s Division of Nutrition, Physical Activity and Obesity is at the forefront of addressing obesity in the U. S. Too many people have obesity. Obesity affects almost 1 in 5 children and more than 1 in 3 adults, putting them at risk for high blood pressure, high cholesterol, type 2 diabetes, heart disease and certain cancers. Obesity costs the US health care system $147 billion a year and over a quarter of all Americans 17 to 24 years are too heavy to join the military. DNPAO protects the health of Americans at every stage of life by encouraging regular physical activity and good nutrition. We support the toddler eating healthy snacks and playing actively in child care, the student being able to walk to school, the mother who chooses to breastfeed, and the older adult who can walk safely and have access to healthy foods in their own neighborhood.

Between 1976-80 and 2007-2008 the percentage of people with obesity doubled among adults and tripled among children. Between 2007-2008 and 2015-2016, the rates have remained steady for children but have continued to increase for adults. The Division of Nutrition, Physical Activity, and Obesity (DNPAO) supports healthy eating, active living, and obesity prevention by creating healthy child care centers, hospitals, schools, and worksites; building capacity of state health departments and national organizations; and, conducting research, surveillance and evaluation studies.
