RESUMO
Objectives: This study aimed to describe correlations between glucose, insulin and adipokine levels and the homeostasis model assessment [HOMA] index with regards to the presence/absence of fat mass and obesityassociated [FTO] rs9939609 and peroxisome proliferator-activated receptor [PPAR]-y rs1801282 single nucleotide polymorphisms [SNPs] as indicators of body mass index in adolescents
Methods: This cross-sectional study was conducted between September and December 2016 in Toluca, Mexico. A total of 71 students between 14-18 years old were included. Various anthropometric and laboratory measurements were collected, including lipid profile, glucose, insulin and adipokine levels and HOMA index. The degree of association between variables was evaluated with regards to the presence/absence of the SNPs
Results: Leptin levels were significantly higher among female students [P = 0.001], although adiponectin levels did not differ significantly [P = 0.060]. There were significant positive correlations between insulin levels and HOMA index with FTO [r = 0.391; P = 0.007 and r = 0.413; P = 0.005, respectively] and PPARa [r = 0.529; P = 0.007 and r = 0.537; P = 0.007, respectively] SNPs. Leptin showed a significant positive correlation in the presence of PPARa [r = 0.483; P = 0.007] or in the absence of both SNPs [r = 0.627; P = 0.039]. However, adiponectin was significantly negatively correlated in the presence of FTO, either alone [r = .0.333; P = 0.024] or in combination with PPARã [r = .0.616; P = 0.043]
Conclusion: The presence of FTO and/or PPARã SNPs might be related to a genetic predisposition to metabolic syndrome
