Vitamin D has been established as a key factor in the development of obesity through the vitamin D receptor (VDR). The aim of this study was to investigate the contribution of the VDR gene to obesity-related phenotypes in a population of Caucasian young adults. The study population consisted of 701 healthy Spanish young adults (mean age 20.41±2.48). Three single-nucleotide polymorphisms (SNPs) of VDR (TaqI, BsmI and FokI) were selected as genetic markers. Body composition measurements including weight, body mass index (BMI), fat mass (FM), percentage of fat mass (PFM, fat-free mass (FFM) and visceral fat level (VFL) were analysed. Differences in obesity traits across the genotypes were determined using analysis of covariance (ANCOVA). The FokI polymorphism showed a significant association with PFM across the whole population after adjusting for age and sex (p=0.022). Age-adjusted analysis revealed an association between body weight and the TaqI and BsmI SNPs in males (p=0.033 and p=0.028, respectively). However, these positive findings did not remain significant after applying the Bonferroni correction for multiple testing. Our findings suggest that VDR genetic variants are unlikely to play a major role in obesity-related phenotypes in a population of Caucasian young adults.

Note Bonferroni correction for multiple testing probably did not have enough gene data, see GWS Forum below
