title: Prevalence of components of the metabolic syndrome in schoolchildren with newly diagnosed type 2 diabetes mellitus.
abstract: OBJECTIVE
  To examine the prevalence of components of the metabolic syndrome (MS) other than hyperglycemia at diagnosis in schoolchildren with type 2 diabetes mellitus (T2DM).
  
  
  METHODS
  The study involved 112 Japanese schoolchildren, 45 males and 67 females aged 12.9 +/- 1.5 yr, who were diagnosed as having T2DM. The body weight, blood pressure and fasting serum triglyceride (TG), and high-density lipoprotein cholesterol cholesterol (HDL-C) levels were also measured at diagnosis. The criteria adopted for the diagnosis of MS were as follows; i.e., TG > or =150 mg/dL, HDL-C <40 mg/dL, systolic blood pressure > or =130 mmHg, and/or diastolic blood pressure > or =85 mmHg. Obesity was defined as percent overweight > or =20.0%.
  
  
  RESULTS
  As much as 83.0% of the patients had obesity. The prevalence of increased TG was 33.0% and that of decreased HDL-C was 21.4% among the patients. Elevated blood pressure was identified in 11.6% of the patients. Of the total, 15.2% of the patients had no other components of MS besides hyperglycemia; 49.1% had only one other component, which was obesity in the majority; 17.0% had two other components of MS besides hyperglycemia, which were obesity and elevated TG in the majority; 18.8% of the patients had three or more components of MS besides hyperglycemia.
  
  
  CONCLUSIONS
  We found a high prevalence of other components of MS besides hyperglycemia in the patients even at the time of diagnosis. Early detection of other components of MS would appear to be of importance for preventing the development of cardiovascular disease in children with T2DM.
