  • b Based on the 2000 Centers for Disease Control gender-specific growth charts for the United States. Available at www.cdc.gov/growthcharts. Overweight and obesity are defined as having a BMI within the 85th to <95th percentile or ≥95th percentile, respectively. Normal wt was defined as having an age- and gender-specific BMI >5th to <85th percentile.
