This meta-analysis aimed to investigate the association of the rs9939609 FTO gene polymorphism and body fat percentage (BF%). To the best of our knowledge, this study is the first meta-analysis to evaluate the relationship between FTO rs9939609 polymorphism and BF%. We searched PubMed, Web of science, Scopus and Embase to identify studies investigating the relations between the rs9939609 FTO gene polymorphism and BF%. Studies that meet inclusion criteria were collected for the final analysis. There was significant differences in the level of BF% between different genotypes of FTO rs9939609 polymorphism, and the carriers of the A allele of FTO rs9939609 polymorphism had higher BF%. The association was significant between carriers of TT genotype compared to carriers of AA (p =.007) and AT genotypes (p =.04), but not between AT and AA genotypes. This study identified that the carriers of the A allele of FTO rs9939609 polymorphism have higher BF%.
