FTO Genotype, Vitamin D Status, and Weight Gain During Childhood

Previous evidence suggests that variants in the fat mass and obesity-associated gene (FTO) affect adiposity in an age-dependent fashion in children, and nutritional factors may modify genotype effects. We assessed the effect of FTO rs9939609 on BMI and BMI-for-age Z score changes during childhood in...

At baseline, 1,088 children aged &lt;10 years had complete genotypic and anthropometric data; 796 were followed up over a median 4.6 years. Baseline vitamin D insufficiency was defined as &lt;75 nmol/L. We observed a 0.07 kg/m(2)/year increase in BMI and a 0.03 Z/year increase in BMI-for-age Z score per rs9939609 risk allele over follow-up (P = 0.01). Vitamin D status significantly modified FTO effects (P for interaction = 0.02). The rs9939609 risk allele was associated with a 0.05 Z/year increase in BMI-for-age Z score among vitamin D-insufficient children (P = 0.003), while no significant genetic effects were observed among vitamin D-sufficient children. Our data suggest that FTO rs9939609 affects child weight gain, and genotype effects are more pronounced among children with insufficient vitamin D levels.</description><identifier>ISSN: 0012-1797</identifier><identifier>EISSN: 1939-327X</identifier><identifier>DOI: 10.2337/db13-1290</identifier><identifier>PMID: 24130335</identifier><identifier>CODEN: DIAEAZ</identifier><language>eng</language><publisher>Alexandria, VA: American Diabetes Association</publisher><subject>Alfacalcidol ; Alpha-Ketoglutarate-Dependent Dioxygenase FTO ; Biological and medical sciences ; Body mass index ; Calcifediol ; Child ; Diabetes.
