Welcome to my blog. Childhood Obesity is a serious issue here in the U.S. Environmental factors greatly increase the risks for children who are obese. Over the past three decades, the childhood obesity rate has more than doubled for preschool children aged 2-5 years and adolescents aged 12-19 years, and it has more than tripled for children aged 6-11 years. At present, approximately nine million children over 6 years of age are considered obese.
