目的了解流动人口孕产妇基本公共卫生服务的利用现状,探索不同流动特征对孕产妇基本公共卫生服务利用的影响。方法利用2014年全国流动人口卫生计生动态监测数据,选取北京市朝阳区、青岛、厦门、嘉兴、深圳、中山6座城市(区)的1 477名流动孕产妇作为研究对象。采用多水平logistic回归模型,分析流动特征对流动孕产妇基本公共卫生服务利用的影响。结果流动孕产妇孕12周内建册和孕期接受5次及以上产前检查的比例分别为89.00%和78.68%,产后访视的接受率为62.38%。其中产前基本公共卫生服务利用在城市水平间存在组内聚集性(ICC=0.14,P<0.01;ICC=0.40,P<0.01)。两水平logistic回归分析显示流动范围、流动时间和流入地流动人口的比例对孕早期建册和产前检查服务的利用均存在影响;流动原因主要影响产前检查服务的利用。单水平logistic回归分析发现流动范围影响孕产妇产后访视服务的利用。结论流动特征不同的流动孕产妇基本公共卫生服务利用水平存在差异。应根据孕产妇的不同流动特征提供针对性、可及性的服务措施。 Objective To understand the status quo of the utilization of basic public health services for migrant women and explore the impact of different mobility characteristics on the utilization of basic public health services for pregnant women. Methods Using the data of 2014 national floating population health monitoring, a total of 1 477 migrant pregnant women in 6 cities (districts) of Chaoyang District, Qingdao, Xiamen, Jiaxing, Shenzhen and Zhongshan were selected as the research object. The multi-level logistic regression model was used to analyze the impact of mobility characteristics on the utilization of basic public health services for migrant women. Results The proportion of prenatal check-up for those who received 5 or more pregnancies within 12 weeks of pregnancy and during pregnancy was 89.00% and 78.68%, respectively. The acceptance rate of postpartum visits was 62.38%. Among them, the use of prenatal basic public health services had intragroup cohesion (ICC = 0.14, P <0.01; ICC = 0.40, P <0.01) in urban areas. Two-level logistic regression analysis showed that the mobile range, the flow time and the proportion of floating population in the first trimester all had an impact on the utilization of early pregnancy screening and prenatal care services; the causes of the flow mainly affected the utilization of prenatal care services. Univariate logistic regression analysis found that the mobile range affected the utilization of postpartum interview services. Conclusion There are differences in the utilization level of basic public health services for migrant women with different mobility characteristics. Should be based on the different characteristics of pregnant women to provide targeted, accessible service measures.
