Abstract

ObjectiveTo identify cutoff points of the Homeostatic Model Assessment for Insulin Resistance (HOMA‐IR) index established for adolescents and discuss their applicability for the diagnosis of insulin resistance in Brazilian adolescents. Data sourceA systematic review was performed in the PubMed, Lilacs and SciELO databases, using the following descriptors: “Adolescents”, “insulin resistance” and “ROC curve”. Original articles carried out with adolescents published between 2005 and 2015 in Portuguese, English or Spanish languages, which included the statistical analysis using ROC curve to determine the index cutoff (HOMA‐IR) were included. Data synthesisA total of 184 articles were identified and after the study phases were applied, seven articles were selected for the review. All selected studies established their cutoffs using a ROC curve, with the lowest observed cutoff of 1.65 for girls and 1.95 for boys and the highest of 3.82 for girls and 5.22 for boys. Of the studies analyzed, one proposed external validity, recommending the use of the HOMA‐IR cutoff >2.5 for both genders. ConclusionsThe HOMA‐IR index constitutes a reliable method for the detection of insulin resistance in adolescents, as long as it uses cutoffs that are more adequate for the reality of the study population, allowing early diagnosis of insulin resistance and enabling multidisciplinary interventions aiming at health promotion of this population.
