Background Obesity is considered a major public health problem in the world. At present, the association of single nucleotide polymorphisms (SNPS) Pro12Ala and C161-T in peroxisome proliferator-activated receptor gamma 2 (PPARγ2) gene with obesity is still controversial. The aim of this study is to evaluate the relationship between the Pro12Ala and C161-T polymorphisms of PPARγ2 gene and obesity among Han nationality of Yunnan Plateau in Southwest China. Methods The genotypes of 284 extremely overweight patients, 475 obese patients and 759 normal controls from Yongsheng County of Yunnan Province (China) were analyzed. The Pro12Ala and C161-T genotypes of PPARγ2 were detected by SNaPshot genotyping assay. The data were analyzed statistically. Results The overall prevalence of obesity was 4.99% and the overweight rate was 23.93% among Han nationality in Yongsheng, Yunnan Province. Statistical analysis showed that there were no significant differences in the Pro12Ala genotype, C161-T genotype and the two combined genotypes between the extremely overweight and the control 1, either between the obesity and the control 2 (P > 0.05). Further, the alleles of Pro12Ala and C161-T did not exhibit any signifificant association with extreme overweight or obesity among the complete sample population (P > 0.05). However, conditional logistic regression analysis showed that there was a statistically significant association between the two combined genotype of “CC + TT” and the extreme overweight after adjusting for covariates (Calculated with the combined genotype of “CC + CC ” as the reference category; P = 0.014; OR = 4.04; 95%CI = 1.33–12.33). Conclusions Our study indicates that the combined genotypes "CC + TT" of PPARγ2 Pro12Ala and C161-T were associated with an increased risk of extreme overweight, however, Pro12Ala and C161-T polymorphisms may not be the main cause of obesity in Han nationality of the Yunnan Plateau in Southwest China. |
