妊娠中期妇女血清铁蛋白水平与妊娠中、晚期贫血相关性研究

目的探讨妊娠中期妇女血清铁蛋白水平与妊娠中、晚期贫血的相关性。方法随机抽取医院产科门诊建卡的孕妇，监测孕妇妊娠24周（妊娠中期）的血清铁蛋白及血红蛋白水平，随访至妊娠38周（妊娠晚期）并检测的血红蛋白。结果妊娠中期血清铁蛋白水平在正常的孕妇妊娠中期贫血发生率为7．08％，低于正常的孕妇妊娠中期贫血发生率为14．01％，两者比较，差异有统计学意义（P〈0．01）；妊娠中期血清铁蛋白水平正常的孕妇妊娠晚期贫血发生率为6．32％，低于正常的孕妇妊娠晚期贫血发生率为20．27％，两者比较，差异有统计学意义（P〈0．01）。结论妊娠中期血清铁蛋白水平低的孕妇在妊娠中、晚期发生贫血的几率显著高于血清铁蛋白正常组，血清铁蛋白水平与妊娠期贫血发生存在较强的相关性，尤其于妊娠晚期更明显。对于孕期监测血清铁蛋白水平低的孕妇应给予铁剂补充。

Correlation between Serum Ferritin Level in Middle Pregnant Women and Anemia in Second and Third Trimester of Pregnancy

Objective To investigate the correlation between serum ferritin level in the sceond trimester of pregnanoy and anemia in the second and third trimester of pregnancy. Methods Pregnant women with the established cards in the obstetric outpatient clinic of our hospital were extracted and performed the monitoring of serum ferritin and hemoglobin levels from 24 weeks （the second trimester of pregnancy pregnancy） to 38 weeks （the third trimester of pregnancy） of gestation. Results The occurrence rate of anemia in the sec- ond trimester of pregnancy with normal range of serum ferrintin was 7.08%, which was significantly lower than 14.01% in those with less than the normal serum ferritin level（P〈 0.01）; the occurrence rate of anemia in the second trimester of pregnancy with normal serum ferritin was 6.32%, which was signifcantly lower than 20.2% in those with less than the normal serum ferritin（P〈0.01）. Conclusion The probability of second and third trimester of pregnancy anemia occurrence in second trimester of pregnancy with low serum ferritin is significantly higher than that in the pregnant women with normal serum ferrintin. The strong correlation exists between serum ferritin level and the pregnant anemia, which is more obvious especially in the third trimester of pregnancy. The pregnant women with low serum ferritin during pregnant monitoring should be given ironsupplements.
