摘要：Several candidate genes in vitamin D synthesis and metabolism have been reported to have a significant association with 25-hydroxyvitamin D (25(OH)D) in Caucasians and African Americans. Few studies have indicated this relationship among Asians, especially in pregnant Minangkabau women, Indonesia. This study was conducted among 180 singleton pregnant women of West Sumatran Vitamin D Pregnant Mother (VDPM) cohort study. Serum 25(OH)D obtained in the third trimester (T3). Genetic risk scores (GRS) were created based on six vitamin D-related SNPs and their association with 25(OH)D levels were tested. Informations on demographics, lifestyle, pregnancy profile, and physical activity were collected using questionnaire. The average of 25(OH)D concentration was 21.21±10.41 ng/mL respectively. Vitamin D-GRS has significantly associated with serum 25(OH)D levels in the third trimester ( p =0.006). However, the synthesis-GRS and metabolism-GRS group of vitamin D-related gene polymorphisms had no association with 25(OH)D concentration at T3 ( p >0.05). A high prevalence of insufficient-deficient vitamin D status at T3 was common. We observed an association between vitamin D-GRS and 25(OH)D concentration. The results of this study provides additional support for possible role of genetic variants in vitamin D-related gene polymorphisms on 25(OH)D concentration during pregnancy. Further replication studies with larger sample sizes are needed to confirm thefindings.
