title: [Prevalence of a high non-high-density lipoprotein cholesterol level in children aged 9-11 years in Mianyang Science City in Sichuan Province, China].
abstract: OBJECTIVE
  To investigate the non-high-density lipoprotein cholesterol (non-HDL-C) level and the prevalence rate of a high non-HDL-C level in children aged 9-11 years in the Mianyang Science City area in Sichuan Province, China.
  
  
  METHODS
  From September to October, 2015, a field investigation was performed for the students from three primary schools in the Mianyang Science City area by cluster sampling. Fasting venous blood was collected for blood lipid tests. The cut-off value of serum non-HDL-C level and prevalence rate of a high non-HDL-C level in children aged 9-11 years in this area were calculated, as well as the prevalence rate of a high non-HDL-C level in obese children.
  
  
  RESULTS
  In the children aged 9-11 years in this area, the cut-off value of non-HDL-C level was 3.67 mmol/L, and the prevalence rate of a high non-HDL-C level was 3.7% (22/589). Compared with the non-obese children, the obese children had a significantly higher serum non-HDL-C level (P<0.01) and a significantly higher prevalence rate of a high non-HDL-C level (10.0% vs 2.9%; P<0.01).
  
  
  CONCLUSIONS
  The cut-off value of serum non-HDL-C level in children aged 9-11 years in the Mianyang Science City area is established. Obesity is associated with an increased prevalence rate of a high non-HDL-C level in children aged 9-11 years.
