Alarming Trend of Waist Circumference in Tehranian Children and Adolescents- Tehran Lipid and Glucose Study

Introduction: The sensitivity and specificity of waist circumference as an independent predictor of non-communicable diseases in young people have been demonstrated. This study aimed at comparing changes in waist circumference of Tehranian children and adolescents over a 3-year interval. Materials and Methods: Height, weight and waist circumference of children (3-10 years) and adolescents (11-19 years) of district 13 of Tehran were measured twice; in 1999 (n=3922) and in 2001 (n=1026,) within the framework of phases 1 and 2 of the Tehran Lipid and Glucose Study (TLGS). BMI was calculated dividing weight (in kg) by height square (in m2). Children and adolescents with BMIs of 25 and 30, at the age of 18 years, were considered overweight and obese, respectively, based on international curves. Results: Mean of waist circumference in male subjects at the ages of 5. 5, 6. 5, 11, 12, 16. 5(p<0. 05), 10, 13. 5 (p
