How is pediatric obesity defined in terms of BMI percentile?

Explanation:
In children, body size is interpreted using BMI in relation to age and sex because kids are growing and BMI changes as they develop. Growth charts provide percentiles that show how a child’s BMI compares with peers of the same age and sex. Obesity is defined as a BMI at or above the 95th percentile for age and sex, meaning the child’s BMI is higher than about 95% of peers. This threshold helps identify excess adiposity beyond normal growth variation. The other options reflect different weight categories: the 85th percentile up to just below the 95th is considered overweight, the 50th percentile is average, and below the 5th percentile indicates underweight. So the 95th percentile cutoff specifically marks obesity.
