Anthropometric data and body composition
Height and weight were measured using a mechanical balance (ASIMED model BARYS PLUS C) equipped with a telescopic height measuring meter to calculate BMI. Cut‐offs to describe nutritional status were those proposed for subjects aged 5–19 years, according to the World Health Organization, converted into z‐scores. Nutritional status classification was: obese: ≥+2 SD; overweight: >+1 SD; normal weight: −1 to +1 SD; thin: ≤−2SD; severely thin: ≤−3SD.
