"Adolescence is a time of transition when it comes to health. On the one hand, teens are much less affected by the minor illnesses that would have kept them at home, in bed, as children. On the other hand, teens are at much greater risk for harm because of their unhealthy and risky behaviors." 

"In part because of a diet high in fast foods, many American children and adolescents are overweight. The technical definition of 'overweight' is based on the body mass index (BMI), which is an adjusted ratio of weight to height. Children and adolescents who are in the upper 5% (very heavy for their height) are defined as being overweight. Using these standards, in 2001 the U.S. Surgeon General announced that childhood obesity had reached epidemic proportions."
