The association between adiponectin and ADIPOQ gene polymorphisms with obesity among young Jordanian women

Abstract

Obesity is a risk for multiple diseases and an independent cause of morbidity and mortality with staggering global rates. Adiponectin is an adipocyte-derived peptide associated with reduced obesity. In this study, the effect of ADIPOQ gene single nucleotide polymorphisms (SNPs) on obesity and adiponectin relationship was examined. The study was conducted on 389 adult females. Obesity was measured using body weight, BMI, percent body fat, and waist and hip ratio. ADIPOQ G276T and I164T SNPs were genotyped using RFLP procedure. Adiponectin plasma levels were quantified using ELISA technique. Adiponectin correlated with all obesity measures (p<0.05). However, when divided according to genotypes, adiponectin remained correlating (p<0.05) with obesity measures in the participants with GT of the G276T SNP but not (p>0.05) with GG and TT of the G276T SNP. With respect to` I164T SNP, the correlations between adiponectin and obesity measures remained in all genotypes except with W/H ratio and %Bf remained in the participants with CC genotype and with W/H ratio in CT/TT genotypes. Further analyses reveled that adiponectin was lower (p<0.05) in the participants with GT versus the GG and TT genotypes of G276T SNP. The data confirms the effect of adiponectin for obesity. It also shows the importance of ADIPOQ SNPs in the relationship between adiponectin and obesity in young adult females.
