Abstract
Although recent studies suggest a possible relationship between the brain-derived neurotrophic factor Val66Met polymorphism and eating disorders, no study has examined the possibility that the Met-Met genotype is associated with a lower body mass index (BMI) in healthy individuals. We examined this possibility in 481 adults (age range 18-82 years) without significant medical or psychiatric history. After adjusting for gender, analysis of covariance showed that persons with the Met-Met genotype had a lower BMI than those with the Val-Met/Val-Val genotypes (22.28 ± 3.77 vs. 24.72 ± 4.81). A similar, though nonsignificant, trend emerged when comparing all three genotypes separately. These findings suggest a possible relationship between Val66Met polymorphism and BMI in healthy adults. Further work is needed to clarify possible mechanisms for this relationship.
