Abstract

The obesity epidemic among children and adolescents in the United States continues to worsen. The most recent analysis of data from the National Health and Nutrition Examination Survey showed that the prevalence of overweight among children and adolescents – defined as a Body Mass Index at or above the 95th percentile on gender-specific BMI-for-age growth charts developed by the Centers for Disease Control and Prevention – increased significantly between 1999-2000 and 2003-2004. Over this period, the prevalence of overweight among children and adolescents aged 2-19 increased 23% – from 13.9% to 17.1%. In 2003-2004, 18.8% of children aged 6-11 and 17.4% of adolescents aged 12-19 were overweight. Roughly comparable proportions of each age group were considered to be at risk of becoming overweight.
