贫血是血液中红细胞数量低于正常范围,无法运输足量的氧至组织,从而引发头晕、乏力、面色苍白等临床症状,甚至引起器质性病变的综合征[1]。贫血不仅是世界上第二大致残因素,也是全球最严重的公共卫生问题之一。妊娠期女性体内会发生一系列生理变化,尤其是妊娠中期以后血容量剧增,其增长速度明显高于血红蛋白(hemoglobin,Hb)数量的增长,容易导致贫血[2]。我国妊娠合并贫血发病率为14.0%左右,其中约50%以上为缺铁性贫血[3]。因受教育程度、职业类型及饮食习惯等不同,全世界发病率存在一定差异[4]。贫血的类型较多,铁缺乏是妊娠合并贫血中最常见病因,对母体、胎儿和新生儿均会造成近期和远期影响,如母体罹患子痫前期/子痫、胎膜早破、产褥期感染和产后抑郁等并发症,胎儿和新生儿发生胎儿生长受限、胎儿缺氧、羊水减少、死胎、死产、早产、新生儿窒息、新生儿缺血缺氧性脑病等,甚至还会造成脑瘫、神经系统发育滞后等远期影响。近年研究发现,妊娠合并缺铁性贫血还会导致子宫肌层收缩功能异常,增加产后出血(postpartum hemorrhage,PPH)的风险,甚至导致产妇死亡[5]
