Methods The blood samples of 78 second-trimester women were collected during the 24-28 gestational weeks. Serum 25 (OH) D and blood hemoglobin levels were measured. The correlations of serum 25 (OH) D with age and blood hemoglobin levels were analyzed by Pearson correlation. ResultsOf the 78 pregnant women, the rates of vitamin D deficiency ( ≤25.0 nmol/L), insufficiency [25.0 nmol/L < 25(OH) D≤50.0 nmol/L], and sufficiency were 65.38%, 30.77%, and 3.85%, respectively. Serum concentration of 25 (OH) D was positively correlated with blood hemoglobin level ( r =0.2746, P =0.015 ). ConclusionVitamin D deficiency or insufficiency is common among the second-trimester women in winter, especially among those with low hemoglobin level.
