Michelle Obama is the chief spokeswoman and promoter, but she does not have staff solely dedicated to carrying out the Let's Move! initiative. Childhood obesity Body mass index (BMI) is a measurement of weight in relation to height that can help to determine weight status. In children, the Centers for Disease Control and Prevention (CDC) determines that a child is overweight if they are above the 85th percentile and lower than the 95th percentile and obese if at or above the 95th percentile. The CDC indicates that there are several factors that can contribute to childhood obesity: genetic factors; behavioral factors including energy intake, physical activity and sedentary behavior; and environmental factors. Overweight and obesity pose many potential risks and consequences: psychological; cardiovascular disease; among additional risks including asthma, hepatic steatosis, sleep apnea, and type 2 diabetes. Today nearly one in five children in the U.S. between ages 6–19 are obese, and one in three are overweight. The childhood obesity rate tripled from 1980 to 1999 creating an epidemic and a generation where children may have shorter life spans than their parents. The Let's Move! initiative focuses on the reform of behavioral factors and environmental factors by focusing on active lifestyles and healthy eating through community involvement, including but not limited to schools, parents, work places, and healthcare providers. Nutrition To promote healthy eating, the Let's Move! initiative emphasizes nutrition information, a next generation food "icon", food nutrition labeling and having pediatricians as partners. The United States Department of Agriculture (USDA) presents its Let's Move food choice guidelines on the webpage called MyPlate, located at ChooseMyPlate.gov. Guidelines take the form of "half all grains eaten should be whole grains" and 37 nutrition tips. Let's Move! also provides consumers with nutrition information through the U.S. Food and Drug Administration (or FDA)'s "New Front-of-Package Labeling Initiative" and "New Menu and Vending Machines Labeling Requirements". Let's Move! advocates healthy eating habits to be promoted by families, schools, and communities. Let's Move! urges mothers to eat more healthily when pregnant and offers links to a special "MyPyramid Plan for Moms" so they can create a personalized and healthy diet. The initiative also provides guidelines for parents to set up and promote healthy eating habits for their entire family and children. In order for healthier eating to be promoted at schools, Let's Move! promotes the USDA's
