Relationship of serum 25-hydroxyvitamin D with bone turnover biomarkers in pregnant women / 中华内分泌代谢杂志

[Summary] A total of 215 pregnant women at mid-gestation were enrolled, and their serum 25-hydroxyvitamin D levels were measured. Of them, 38 (17. 7%) were classified as cases with vitamin D sufficiency, 70 (32. 5%) as insufficiency, and 107 (49. 8%) as deficiency. Compared with the sufficient group, parathyroid hormone level increased and osteocalcin level decreased significantly in the deficient group. Therefore, vitamin D deficiency is highly prevalent among pregnant women and is associated with their potential disorder of bone turnover.
