The results showed that the prevalence of risk allele (allele C) was higher in obese group than that in normal group (0.964 vs After adjusting for age, sex, there was an association between SNP rs6548238 and obesity in the children of the recessive model (the children with CC genotype had 1.8 times higher risk of obesity than the children with TT and CT genotypes) and of the additive (per allele C) model (one allele C increased the risk of obesity by 1.7 times).
