Abstract:

Objective

To measure the serum 25-hydroxyvitamin D levels in pregnant women from a District of Suzhou and explore its influencing factors.

Methods

Two hundred healthy pregnant women who received routine prenatal examination in a District of Suzhou from October 2019 to June 2020 were selected. The content of serum 25-hydroxyvitamin D was detected by enzyme-linked immunosorbent assay.

Results

The average level of serum 25-hydroxyvitamin D in 200 pregnant women was (26.9±2.3) ng/ml. Only 12 (6.0%) pregnant women had sufficient 25-hydroxyvitamin D. Age and pre-pregnancy body mass index (BMI) had significant effects on serum 25-hydroxyvitamin D levels. Serum 25-hydroxyvitamin D level in pregnant women aged ≤ 25 years was significantly lower than those of pregnant women aged 26-29 years and 30-34 years (P<0.05). Serum 25-hydroxyvitamin D level was significantly lower in pregnant women who were pre-pregnancy overweight and obese than in those who had a normal BMI (P<0.05). Gestational weeks had no significant effect on 25-hydroxyvitamin D level in pregnant women (P>0.05).

Conclusion

25-hydroxyvitamin D deficiency is common among pregnant women detected in this study, which has a certain correlation with age and BMI.
