Background Undergraduate students constitute a relevant population for investigating genetic and body weight-related factors associated with vitamin D deficiency. This study aimed to assess the associations of the VDR BsmI single nucleotide polymorphism (SNP) and body weight status, including obesity, with vitamin D deficiency in undergraduate students. Methods and Results This cross-sectional study included biochemical and ge...

Obesity, characterized by excessive accumulation of body fat, is associated with reduced vitamin D levels. Several polymorphisms of the vitamin D receptor exist, such as TaqI (rs731236), although their association with obesity remains inconsistent. The aim of this study was to evaluate the effect of TaqI polymorphism on biomarkers in individuals with obesity. The study has been approved by the Research Ethics Committee of the...
