Vitamin D Status and Bone Mineral Density is Influenced by Vitamin D Supplementation and Vitamin K1 Intake in Adults with Diabetes and Chronic Kidney Disease.
Patients with diabetes (DM) and chronic kidney disease (CKD) are at increased risk for suboptimal bone health. The study objective was to investigate the relationships between vitamin D (vitD), vitamin K1 (vitK1), and calcium intake with bone mineral density (BMD) and vitamin D status in an ambulatory population with DM and CKD.
Adults (age 18-80 years; n?=?62) with DM and CKD (stages 1-4) were recruited from the Northern Alberta Renal Program. Primary outcome variables included vitD, vitK1, and calcium intake; serum 25(OH)D, 1,25(OH)2D; and BMD as measured by dual X-ray absorptiometry. Statistical significance was determined at P?1000 IU/D). BMD was positively influenced by serum 25(OH)D. However, serum 25(OH) =100 nmol/L was associated with lower BMD (absolute and T-scores) for whole-body and spine (P?=?0.05). VitK1 intake (=200 µg/day) was associated with higher whole-body and femoral-neck BMDs (absoluteand T-scores; P?=?0.05).
VitD status and BMD in adults with DM and CKD was influenced by vitD supplementation and vitK1 intake.
