This study aimed to evaluate the predictive power of the conicity index as well as your cut points to changes in lipid profile in adolescents. It is a Cross-sectional study that evaluated 774 students of both genders, ages 10 to 14 years participating in the Longitudinal Study Sedentary Behavior, Physical Activity, Eating Habits and Health of Adolescents (Study LONCAAFS) in Joao Pessoa, PB. anthropometric data were obtained (weight, height and waist circumference), demographic (gender and age) and performed blood collection after 12 hours of fasting for lipid profile. The conicity index was calculated according to the formula proposed by Valdez. ass were investigated following changes in lipid profile, considering indicative cutoffs abnormalities: total cholesterol (≥170mg / dL), LDL-C (≥130mg / dL), triglycerides (≥130mg / dL), HDL-C (<45 mg / dL). To analyze the predictive power of conicity index and its cutoff, was used to analyze the curves Receiver Operating Characteristic (ROC) with 95% confidence interval. This study was approved by the Ethics Committee. The prevalence of alterations in the lipid profile was 11.25% of hypertriglyceridemia, hypercholesterolemia 32% and 58.5% of hypoalphalipoproteinemia. Overall, the index THAT was a reasonable predictor of changes in the lipid profile of adolescents. The cutoff points of the C index were 1.16 and 1.14 for boys 10-11 years and 12-14 years, respectively. In girls aged 12-14 years, the C index was a good predictor only for the altered LDL-C, with the cutoff point for the C index of 1.14. For other lipid abnormalities, the C index was a reasonable predictor, with a cutoff point of 1.12 girls. The conicity index is a reasonable anthropometric indicator to predict changes in the lipid profile of adolescents. Thus, these values can be used for screening the population of adolescents and those with similar characteristics to changes in lipid profile.
