Introduction. Obesity is considered a public health problem. Its presence at an early age implies an obligation to identify the onset of complications such as insulin resistance and diabetes mellitus (DM). Methods. Observational, descriptive and transversal study. Participated 1206 teenage women. Obesity was defined with BMI values ≥95p according WHO. Serum levels of insulin, glucose and lipid profile were determined. The Homeostasis Model of Assesment Index (HOMA-I) was used, using the Matthews equation with the value ≥ 3,16 to define insulin resistance (RI). For dyslipidemias: hypercholesterolemia ≥ 200 mg/dL, low HDL-C ≤ 40 mg/dL, high C-LDL ≥ 130 mg / dL and hypetriglyceridemia ≥ 130 mg/dL. The obese teenagers with RI underwent an oral glucose tolerance test (PTG): glycemia of 140 to 199 mg / dL intolerant to glucose and ≥ 200 mg/dL as diabetic. Results 25,1% (303) of the population was obese; 246 obese adolescents participated in the biochemical evaluation, 28,1% (69) of them presented RI. In the obese teenagers with and without IR, the average of the biochemical variables in the former were higher, these differences being statistically significant, except for HDL-C. Differences between the prevalence of dyslipidemias were significant except for HDL-C. The IR presented an OR of 10,9 (CI 5,4-26,6), 12,1 (CI 4,9-30,1), and 7,6 (CI 3-19,5) with hypertriglyceridemia, hypercholesterolemia and high LDL-C. The PTG showed 3,3% intolerant and none diabetic. Conclusions: 28,1% (69) of obese adolescents presented RI; no study participant presented DM.
