According to NCCOR, childhood obesity in the United States is a growing public health problem that affects nearly a third of youth who are considered overweight or obese. This is more than 23 million children and teenagers . Since 1980, the obesity rate has more than doubled in all age groups tested. In addition, prevalence of obesity is rising faster among black and Hispanic children according to the National Longitudinal Survey of Youth. Efforts to address this growing public health problem include:
• Various studies on Childhood Obesity with the creation of databases such as National Collaborative on Childhood Obesity Research 
• Evaluating Obesity Prevention Efforts to develop a concise and applicable plan to measure nation’s progress on obesity prevention efforts .
• States Passed laws that address childhood obesity. For example, California: requires licensed child day care facilities to serve only low-fat or nonfat milk to children ages 2 or older, limit juice to 1 serving per day and no beverages with added sweeteners, natural or artificial, except in baby formula or nutritional products for children. Safe, clean drinking water also needs to be made available throughout the day .
