目的 了解通州区孕妇孕晚期贫血状况,分析相关影响因素,为制定防治孕晚期贫血的干预措施提供依据。方法 收集2013年1月—2017年12月在北京市通州区妇幼保健院住院分娩的32 097例单胎孕妇的血红蛋白、社会人口学特征、本次妊娠情况等资料,对孕妇的孕晚期贫血状况进行描述,采用卡方检验及二元Logistic回归分析相关影响因素。结果 32 097例单胎孕妇孕晚期贫血率13.0%,其中轻度贫血占85.3%,中度贫血占14.7%。多因素回归显示未在孕前三个月(至少一个月)至孕早期三个月服用叶酸(OR=1.41,95%CI=1.27～1.57)、非本市户籍(OR=1.12,95%CI=1.04～1.20)、孕前低体重(OR=1.25,95%CI=1.12～1.40)、初中及以下文化程度(OR=1.47,95%CI=1.31～1.66)、高中(OR=1.22,95%CI=1.13～1.33)、经产妇(OR=1.25,95%CI=1.16～1.35)是孕晚期贫血的危险因素。孕前超重肥胖(OR=0.74,95%CI=0.67～0.81)是孕晚期贫血的保护因素。结论 北京市通州区住院分娩的孕妇孕晚期贫血问题不容忽视,应采取有效预防措施以减少贫血发生。
