Objective To test the hypothesis that cardiovascular disease (CVD) risk factors are similar in nondiabetic (non-DM) adolescents compared with those with type 1 diabetes (T1D) in the most insulin-sensitive (IS) tertile, and that CVD risk factors are more atherogenic with decreasing IS in adolescents with T1D. Study design IS for adolescents with T1D (n = 292; age = 15.4 +/- 2.1 years; duration = 8.8 +/- 3.0 years, hemoglobin A1c = 8.9% +/- 1.6%) and non-DM controls (n = 89; age = 15.4 +/- 2.1 years) was estimated using the model: logeIS = .64725 - 0.02032 (waist [cm]) - 0.09779 (hemoglobin A1c [%]) - 0.00235 (triglycerides [mg/dL]). CVD risk factors (blood pressure, fasting total and low-and high-density lipoprotein-cholesterol (HDL-c), high sensitivity C-reactive protein, and body mass index z score) were compared between all non-DM adolescents and those with T1D in the most IS tertile, and then examined for a linear trend by IS tertile in adolescents with T1D, adjusted for sex, race/ethnicity, and Tanner stage. Results Estimated IS was significantly lower in adolescents with T1D compared with those without (T1D = 7.8 +/- 2.4, non-DM = 11.5 +/- 2.9; P < .0001). CVD risk factors were similar for non-DM compared with the adolescents with T1D with the most IS, except for higher (HDL-c) and diastolic blood pressure in adolescents with T1D (P < .05). Among adolescents with T1D, all CVD risk factors except for (HDL-c), were more atherogenic across decreasing IS tertiles in linear regression analysis (P < .05). Conclusion Adolescents with T1D who are the most IS have similar CVD risk factors compared with non-DM adolescents. CVD risk factors are inversely associated with IS in adolescents with T1D. IS may be an important therapeutic target for reducing CVD risk factors in adolescents with T1D. (J Pediatr 2013;162:297-301).
