Background: Excess weight, inflammation, and insulin resistance (IR) are associated, but the prevalence of and biomarkers for IR in Latin children are unknown.
Purpose: This study aimed to determine the prevalence of IR in prepubertal and pubertal Latin children with excess weight and explore the usefulness of different biomarkers of low-grade inflammation for identifying IR status.
Methods: Sixty-eight children (31 boys, 37 girls; approximately 11 years of age) with excess weight (overweight and obese) and 20 healthy normal-weight children (12 boys, 8 girls; approximately 12 years of age) were included. Anthropometric parameters, insulin, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, tumor necrosis factor- α (TNF-α), interleukin (IL)-6, monocyte chemoattractant protein-1 (MCP-1), soluble CD40 ligand (sCD40L), high-sensitivity C-reactive protein (hs-CRP), and myeloperoxidase were assessed and IR was determined by homeostasis model assessment index (cutoff points: 2.67 and 2.22 in prepubertal boys and girls and 5.55 and 3.82 in pubertal boys and girls, respectively). Intergroup differences were compared, correlations were investigated using Pearson correlation coefficient, and stepwise multiple linear regression analyses were performed to estimate the relationship between inflammatory biomarkers and IR.
Results: The prevalence of IR among overweight children was 62%. IL-6 levels differed between overweight and obese boys, while erythrocyte sedimentation rate, MCP-1, TNF-α, IL-6, hs-CRP, and sCD40L differed between obese and normal-weight boys. In contrast, sCD40L levels were increased in overweight versus normal-weight girls, while MCP-1, TNF-α, IL-6, and sCD40L differed between obese and normal-weight girls. Furthermore, MCP-1 and sCD40L levels and erythrocyte sedimentation rate were positively correlated with IR; however, a stepwise regression analysis that adjusted for the body mass index (BMI) z score, sex, and age showed that none were good predictors of IR status.
Conclusion: The prevalence of IR is high among Latin children with excess weight. Although some inflammatory biomarkers differed among groups, none robustly predicted IR.
