【摘要】 目的　了解孕妇缺铁性贫血在妊娠各孕周期的发生规律、提出干预措施 ,提高保健质量。方法　对 5 2 1例缺铁性贫血孕妇分别按照孕 12W～ 19W、孕 2 0W～ 2 7W、孕 2 8W～ 3 5W、孕 3 6W～ 40W 4个孕周组分析各孕周组贫血的发生率。结果　妊娠期孕妇贫血总发生率为 16 87%。随着孕周的进展其贫血率升高 ,孕 2 0W以后贫血率显著升高 ,SF、Fe、TS下降明显 ,孕 2 8W～ 3 5W贫血率达高峰占 2 6 3 7%。而铁缺乏症发生率高达 80 5 0 %。SF、Fe、TS降至最低点 ,处于贮铁耗尽状态 ,反之ZPP明显上升。结论　缺铁性贫血需从孕 12孕周开始预防性治疗 ,孕 2 8W后Hb <10 5g/L者需考虑诊断为缺铁性贫血 ,及时增加营养及补铁治疗更多还原

【Abstract】 Objective To Study on regularity of iron deficient anemia(IDA) in gravida, provide preventive methods and improve hygienic quality.Methods IDA incidence rate of 12W～19W, 20W～27W, 28W～35W, 36W～pregnant duration were anlyzed in 521 gravida.Results The incidence of IDA in gravida was 16 87% and increased with the development of pregnancy.After 20 weeks of pregnancy,the incidence of IDA markedly increased accompanied with by the decreased Fe, SF and TS, especially during the 28～35 weeks of pregnancy, which reached the peak with the anenia incidence of 26 37%,and 80 50% of cases was irom deficient symptom,it suggesting iron deficiency in this stage and Fe, SF, TS decreased to the lowest level and the stored iron was almost exhausted and ZPP increased.Conclusions After 12 weeks of pregnancy,gravida should be supplemented with iron agent. It’s also suggested that those gravida with gestational age older than 28 weeks with the Hb levels of less than 105g/L should be considered as IDA and should be treated with iron supplement. [更多还原
