The contribution of polymorphism in VDR gene FОKI in the development of osteopenia in pregnancy

Abstract

The study involved 89 postpartum women and 97 nonpregnant women aged 20 to 35 years. The results of a genetic test compared with the BMD. In parturients in the lumbar spine the highest IPC and the value of the Z-scores were in patients with genotype FF, and the lowest with the genotype ff. Patients with the heterozygous genotype were charac terized by intermediate values of the BMD and Z-scores in the lumbar spine. A similar results was observed in the proximal femur and the distal forearm. The results of the correlation analysis showed a moderate negative correlation between the ff genotype and the level of BMD in lumbar spine (r = –0,44; p < 0.05) and proximal femur (r = –0.37; p < 0.05).
