Comparison of serum levels of vitamin d and vitamin d-binding protein in normal, osteopenic and osteoporotic postmenopausal women

Abstract

Objective: To compare the serum levels of vitamin D, vitamin D binding protein (VDBP) calcium and phosphate in normal, osteopenic and osteoporotic postmenopausal women categorized on the basis of bone mineral density (BMD) scores. Methods: A cross sectional study carried out from May 2017 to August 2018. BMD measured by Dual energy X-ray Absorptiometry categorized women (aged 20-70 years) into normal (n=37) (T score ≥-1.0) osteopenic (n=25) (-2.5< T score, < 0.0001. Conclusion: Vitamin D and VDBP are linked with bone health and estimation of VDBP appears to be a valuable tool for the assessment of increased bone loss and possible risks of bone fractures especially in postmenopausal women.
