ABSTRACT
BACKGROUND AND AIMS:
Interleukin-6 is an inflammatory response mediator used as a metabolic marker of obesity. Polymorphisms IL6 -597C>A, -572G>C, and -174G>C modify the production of this protein. The associations between these haplotypes and obesity or metabolic markers have not been studied in adolescents, so an analysis of these associations was performed.METHODS:
The cross-sectional study included 745 apparently healthy 14- to 19-year-old adolescents. Obesity, serum glucose, insulin, triglycerides, total cholesterol, low-density lipoprotein-cholesterol, high-density lipoprotein-cholesterol (HDL-C), and high-sensitivity C-reactive protein (hs-CRP) were evaluated, and IL6 -597G>A, -572G>C and -174G>C polymorphisms determined. The associations were analyzed using multivariate logistic regression models.RESULTS:
The allele frequencies were 0.15 for -597A and -174C and 0.30 for -572C. Genotypes were in Hardy-Weinberg equilibrium. IL-6(-597/-572/-174) haplotypes GGG, GCG, and AGC comprised 99.74% of the total haplotypes. The associations were significant between genotype GCG/GCG and hyperglycemia (OR = 2.86, 95% CI = 1.02-7.97); between GCG/GCG and high hs-CRP (OR = 6.17, 95% CI = 1.13-33.77); between AGC/AGC and obesity (OR = 4.42, 95% CI = 1.40-14.01); and between GGG/GCG and low HDL-C (OR = 1.53, 95% CI = 1.03-2.28).CONCLUSIONS:
Genotypes of the IL6(-597/-572/-174) polymorphisms are associated with metabolic risk factors in Mexican adolescents.
