History of Childhood ObesityChildhood obesity statistics in the United States have caught the attention of every aspect of our nation recently. Between 16 and 33 percent of children and adolescents are obese. Obesity is among the easiest medical conditions to recognize but most difficult to treat. Unhealthy weight gain due to poor diet and lack of exercise is responsible for over 300,000 deaths each year. The annual cost to society for obesity is estimated at nearly $100 billion. Overweight children are much more likely to become overweight adults unless they adopt and maintain healthier patterns of eating and exercise.
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.
Trends in childhood and youth obesity mirror a similar profound increase over the same approximate period in U.S. adults as well as a concurrent rise internationally, in both developed and developing countries.
The obesity epidemic affects both boys and girls and has occurred in all age, race, and ethnic groups throughout the United States. In addition to the increase in obesity prevalence, the heaviest group of children is getting heavier whereas the leanest group of children is staying lean.
What this means is that among younger age groups of children 6 to 11 years of age, and to a lesser extent adolescents, the lower part of the BMI distribution appears to have changed little over time.
