title: [Diagnosis boundary values of metabolic syndrome obesity index for children and adolescents].
abstract: OBJECTIVE
  To determine the distribution characteristics of waist circumference (WC), waist height ratio (WHtR) of 6-18 years olds in Guangzhou, and to put forward the WC and WHtR appropriate boundary values for 6-18 years olds on the basis of cardiovascular disease (CVD) risk factor assessment.
  
  
  METHODS
  We analyzed the height, weight, WC and its metabolic indication data (blood pressure, fasting blood glucose, and blood lipids) of 15 000 children in Guangzhou, aged 6-18, with the receiver-operating characteristic curve (ROC), and explored the best value point of WC and WHtR for the prediction of cardiovascular diseases.
  
  
  RESULTS
  When the WC percent reached P85, and WHtR reached 0.48, the cardiovascular risk factors of fasting blood-glucose, blood pressure, and blood fat were significantly higher.
  
  
  CONCLUSIONS
  The 85th percentile value of WC and 0.48 of WHtR are the appropriate boundary values in increasing the cardiovascular disease risk factors in Chinese children and teenagers. WC and WHtR as a relatively simple inspection method, can well predict cardiovascular diseases, and be used in the conventional measuring items among students.
