title: Dyslipidemia in Iranian overweight and obese children.
abstract: OBJECTIVE
  To evaluate the frequency and patterns of dyslipidemia in overweight and obese children and to determine the extent of blood lipid abnormality in overweight and obese children.
  
  
  METHODS
  A prospective matched case control study on 230 overweight and obese children and adolescents (body mass index [BMI] > 85th percentile) aged 4 to 18 years undertaken at the outpatient endocrine clinic of the Childrens' Hospital at Tabriz University between 2006-2008. This study was conducted to compare the frequency of abnormal plasma lipid levels in overweight and obese children compared with 50 nonobese children (BMI = 50th-85th percentile).
  
  
  RESULTS
  The total frequency of dyslipidemia was 69.58%. The prevalence of dyslipidemia increased with severity of obesity and reached 76.9% in the severely obese (P < 0.005). High triglycerides was the most common dyslipidemia in combination (26.08%) and in isolation (18.6%). There was a significant difference in mean of triglycerides between the severely obese and other groups (P < 0.004).
  
  
  CONCLUSIONS
  In the present study, dyslipidemia is more common in severely obese children and the most common component of dyslipidemia is a high triglyceride level.
