Is the rs9939609 polymorphism in the FTO gene associated with fat and fiber intakes in patients with type 2 diabetes? Context: The common polymorphism in the FTO gene (rs9939609) has been associated with obesity, type 2 diabetes, and appetite regulation. The aim of this study was to evaluate possible associations of FTO rs9939609 with dietary factors in patients with type 2 diabetes. This was a cross-sectional study of 236 patients with type 2 diabetes (age 60.0 ± 10.3 years; diabetes duration 12.7 ± 8.2 years; 53.4% females) who were genotyped for FTO rs9939609. Patients underwent clinical and laboratory evaluations and 3-day weighed diet records. Data on dietary intake were categorized as high or low, based on median values. The AA genotype in the FTO gene was positively associated with high fat (>34% energy; OR = 2.17; 95% CI 1.02-4.63) and low fiber intakes (<16 g/day; OR = 2.42; 95% CI 1.05-5.57), adjusted for gender, BMI, total energy intake, systolic blood pressure, and HbA1c. When gender was taken into account, AA females had higher fat (37.4 ± 5.3 vs. 32.6 ± 7.5 and 32.2 ± 6.2% energy; p = 0.005) and lower fiber intakes (12.4 ± 4.4 vs. 15.1 ± 6.3 and 16.7 ± 5.6 g/day; p = 0.023) than patients with TT and AT genotypes. Multiple logistic regression models confirmed female associations for high fat (OR = 9.73; 95% CI 2.12-44.66) and low fiber intakes (OR = 4.28; 95% CI 1.14-16.06; p < 0.05 for all models).

Patients with type 2 diabetes, who were carriers of the AA genotype of the FTO rs9939609, had increased fat and decreased fiber consumption, independently of BMI. Final Decision: yes
