Resumo

Objective: We investigated whether or not the UCP1 -3826 A>G polymorphism is associated with obesity and related metabolic disorders in grade III obese patients. Methods: 150 obese patients (body mass index >= 35 kg/m(2)) who were candidates for bariatric surgery were studied. Weight (kg), body mass index (kg/m(2)); fat free mass (kg), fat mass (kg), energy intake (kcal), level of physical activity, plasma levels of glucose, total cholesterol, low-density lipoprotein, high-density lipoprotein (HDL), triacylglycerols, and the prevalence of comorbidities associated with obesity were collected from medical records. Polymorphism rs1800592 genotyping was performed through allelic discrimination method in real time polymerase chain reaction using the TaqMan predesigned SNP Genotyping Assays kits. The t test was done to determine if genotypes of each polymorphism are associated with anthropometric and body composition variables. Linear regression models were used for age, sex, height, physical activity, and energy intake in weight and body composition variations (P < 0.05). Results: Among these 150 individuals (47.2 +/- 10.5 y, 80% women) the distribution of AA, AG, and GG was 41.3%, 45.3%, and 13.4%, respectively. Weight and body fat were lower in individuals who were carriers of a mutated allele G. It was observed that mutated homozygotes (GG) had a lower frequency of type 2 diabetes mellitus compared with those of wild allele (AA+AG). Conclusions: UCP1 -3826 A>G polymorphism is associated with weight, body fat mass, and risk of type 2 diabetes mellitus in obese individuals candidates for bariatric surgery. (C) 2016 Elsevier Inc.
