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).
