Abstract
Background. Recent studies have demonstrated possible association between vitamin D deficiency and atherogenic dyslipidemia. However, there are practically no results from Russian investigations in this field. Objective. To assess serum lipids in women carrying various vitamin D receptor (VDR) gene variants. Design and methods . The study included 697 women aged between 35 to 55 years (mean age 43,4 ± 0,3 years). Anthropometric data including height, waist circumference, body mass index were measured. Serum lipid profile, 25-hydroxyvitamin D (25(OH)D) level and four VDR gene polymorphisms BsmI (rs1544410), ApaI (rs7975232), TaqI (rs731236), and FokI (rs2228570) were evaluated. The results showed high prevalence of abdominal obesity, dyslipidemia, vitamin D insufficiency/deficiency in the study group and 2,6 increased risk of high-density lipoprotein (HDL) cholesterol reduction in women with vitamin D deficiency. There were no differences in serum 25(OH)D between VDR genotypes. GG (BB) genotype carriers of BsmI (rs1544410) demonstrated higher triglyceride levels than subjects with GA, AA (Bb, bb) genotypes. Women with TT (AA) и TG (Aa) genotypes of ApaI (rs7975232) had higher total cholesterol and low-density lipoprotein (LDL) cholesterol levels compared to GG (aa) genotype carriers. Conclusions. The study revealed the associations between low vitamin D status and decreased HDL cholesterol as well as between BsmI (rs1544410) and ApaI (rs7975232) VDR genotypes and atherogenic dyslipidemia.
