Factor analysis, correlation, binary logistic regression and receiver operating characteristic analysis were used to evaluate combinations of these biomarkers as possible diagnostic tools for IR.Results: Two biomarker IR models combining levels of triglycerides (TG)/HDL, eotaxin, MCP-1 and PDGF-BB in pubertal patients with obesity of both sexes were defined. Altered levels of MCP-1, eotaxin, and PDGF-BB constitute a main component that determines 27.7% of the variance explaining IR. Growth and inflammatory factors comprise two other components linked to the first, together accounting for 59.2% of the variance determining IR.Conclusions: PDGF-BB, MCP-1, eotaxin, TG and cholesterol concentrations constitute a solid panel of biomarkers associated with IR in pubertal children with obesity that could be useful in their stratification in a clinical setting for stratification.
