Abstract

Abstract:

Objective To study serum 25-hydroxyvitamin D [25（OH）D] levels in pregnant and non-pregnant childbearing age women,and to guide the basic healthy care for perinatal women. Methods A total of 136 pregnant women and 122 non-pregnant childbearing age women were enrolled. The data,such as age,calcium supplements,multivitamin supplements and outdoor activity time per day,were collected through questionnaires. Serum 25（OH）D levels were determined by enzyme-linked immunosorbent assay（ELISA）.Results The levels of serum 25（OH）D were（45.40±13.26）nmol/L in pregnant group and（34.90±9.18）nmol/L in non-pregnant group（P<0.05）. The proportions of vitamin D deficiency and insufficiency were 61.76% and 37.50% in pregnant group,and the proportions of vitamin D deficiency and insufficiency were 89.34% and 10.66% in non-pregnant group. Conclusions Pregnant women have higher serum 25（OH）D levels than non-pregnant childbearing age women. Vitamin D deficiency or insufficiency phenomenon is common.
