Obesity in Childhood and Adolescence

In the guidelines, young people who have a body mass index that meets or exceeds the 95th percentile for kids of the same age and gender are considered obese. The growth charts are based on NHANES data from the 1960s through the early 1990s. So basically the definition of obesity is not that you're fatter than 95% of kids in the 1960s. And also, as you mentioned, the entire episode, those percentile rankings, they're just descriptive. They're not based on like health risks.
