| Abstract |
The aim of this study was to investigate the prevalence of Metabolic Syndrome and its components by sex, year, and obesity in Korean Children and Adolescents. The Metabolic Syndrome was defined using the criteria of IDF(International Diabetes Federation) in Children and Adolescents aged 10 to 19 years who have participated in the KNHANES in 2007 (n=512), 2008 (n=1105), 2009 (n=1191) and 2010 (n=923). The combined prevalence of metabolic syndrome in Korean Children and Adolescents was 3.1% in 2007, 1.2% in 2008, 1.3% in 2009, 1.0% in 2010. The Korean Children and Adolescents has not significantly changed 2007 to 2010. The prevalence of metabolic syndrome was highest in obese Children and Adolescents. To find the optimal, maximal sensitivity and specificity for BMI, waist circumference, the ROC (Receiver output curve) analysis of cut-off points against Fasting Blood Glucose (100 mg/dl) and Triglyceride (150 mg/dl). BMI 85 percentile was the best cut-off levels for determining the subjects with Fasting Blood Glucose over 100mg/dl and Triglyceride over 150 mg/dl. Waist Circumference 75 percentile was the best cut-off levels for determining the subjects with Fasting Blood Glucose over 100 mg/dl and Triglyceride over 150 mg/dl. |
