title: Association of fasting insulin with serum lipids and blood pressure in Kuwaiti children.
abstract: To examine the association of hyperinsulinemia with the atherogenic risk profile in children, we studied the relationships of the fasting plasma insulin level with indices of obesity (body mass index [BMI] and sum of triceps and subscapular skinfold thickness [SFT]), body fat distribution (waist to hip ratio [WHR]), serum lipid, lipoprotein, and apolipoprotein levels, and blood pressure in a case-control study of 460 Kuwaiti prepubertal obese children aged 6 to 13 years matched by age and sex to 460 prepubertal non-obese controls. Obese children were ascertained in a representative cross-sectional study of 2,400 school children. Fasting insulin levels were positively correlated (P < .001) with serum triglyceride (TG) and very-low-density lipoprotein (VLDL) cholesterol levels and negatively correlated with high-density lipoprotein (HDL) cholesterol levels. No significant associations were observed between insulin and total cholesterol (TC), cholesterol, low-density lipoprotein (LDL) or apolipoprotein A-I (apo A-I). Stronger associations of insulin levels with lipoprotein fractions were observed in obese versus non-obese controls. Obese children had a higher concentration of apo B and a lower apo A-I:B ratio (P < .001). Insulin and the insulin to glucose ratio increased with age in obese children, whereas there were slight changes in non-obese children. TG and HDL cholesterol levels and systolic blood pressure (SBP) were significantly different across insulin quartiles in boys and girls. We conclude that the fasting plasma insulin level may be used as a marker for the development of obesity-associated metabolic disorders and elevated blood pressure in children.
