title: Insulin resistance syndrome in adolescents.
abstract: To explore whether the so-called insulin resistance syndrome can be identified in adolescents, serum insulin level was measured in 842 healthy Swedish adolescents (462 boys and 380 girls) and the values were related to current serum lipoprotein and apolipoprotein values (triglyceride [TG], total cholesterol [TC], high-density lipoprotein cholesterol [HDL-C), low-density lipoprotein cholesterol [LDL-C], apolipoprotein [apo] A-I, apo B, and lipoprotein(a)), blood pressure (BP), and anthropometric measurements and previous physical growth. Mean serum insulin values were higher in 14-year-olds as compared with 17-year-olds and were highest in midpuberty. Adolescents with a high serum insulin had a higher attained height and weight during infancy and childhood. Obesity (body mass index [BMI] > 30 kg/m2) was found in 1% of both boys and girls, and hypertensive BP levels were found in 3% of the boys and 1% of the girls. Controlling for age, serum insulin correlated positively with BMI (r = .36 and .25 in boys and girls, respectively), TG (r = .32 and .14), LDL-C (r = .17 and .24), and apoB (r = .23 and .23) and negatively with HDL-C (r = -.13 and -.21). High serum insulin, TG, LDL-C, and BP and low HDL-C clustered in adolescents with high BMI. In conclusion, the findings of this study indicate that features typical of the insulin resistance syndrome are already present in adolescents.
