𝑛 = Number of adolescents who reported their weight and height in the sample.
1Criteria for overweight: IOTF [33]. The criteria for overweight include obesity.
2Prevalence of adolescents whose BMI exceeded the age and gender specific cut off point for overweight but not for obesity (corresponds to the threshold of 25 kg/m2 for adult overweigh).
3Prevalence of adolescents whose BMI exceeded the age and gender specific cut off point for obesity (corresponds to the threshold of 30 kg/m2 for adult obesity).
