Serum 25-hydroxy vitamin D status in the second-trimester women in winter / 中华临床营养杂志

ABSTRACT

ObjectiveTo investigate the serum concentration of 25-hydroxy vitamin D [25(OH)D] in the second-trimester women in winter and explore its correlation with age and blood hemoglobin level. 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.
