Normal weight BMI <17.15 kg/m^{2} for females and <17.42 kg/m^{2} for males. | ||||

Overweight BMI ⩾17.15 kg/m^{2} and <19.17 kg/m^{2} for females and ⩾17.42 kg/m^{2} and <19.30 kg/m^{2} for males. | ||||

Obese BMI ⩾19.17 kg/m^{2} for females and ⩾19.30 kg/m^{2} for males. | ||||

At age 14:

Normal weight BMI <23.34 kg/m^{2} for females and <22.62 kg/m^{2} for males. | ||||

Overweight BMI ⩾23.34 kg/m^{2} and <28.57 kg/m^{2} for females and ⩾22.62 kg/m^{2} and <27.63 kg/m^{2} for males. | ||||

Obese BMI ⩾28.57 kg/m^{2} for females and ⩾27.63 kg/m^{2} for males. | ||||
