Childhood Obesity at Age 12: WHO BMI Thresholds

The WHO defines childhood obesity as a BMI ≥ 95th percentile on age- and sex-specific growth charts. For 12-year-olds, this corresponds to approximately:

  • Girls: 23.3 kg/m²
  • Boys: 22.3 kg/m²

BMI is a screening tool; clinical assessment should also consider body composition, physical activity, and overall health.
