Abstract: Background　Due to current backward supervision of explosively increased maternal and infant health information，the discrimination of such information has become a major challenge to pregnant women. Objective　To explore pregnant women's ability of discriminating maternal and infant health information and associated factors. Methods　From November 2016 to August 2017，the survey was conducted among pregnant women recruited from Children's Hospital of Shanxi，Boai Hospital of Shanxi Province and Taiyuan Jinyuan District Jinsheng Town Health Center. A questionnaire designed by our research group was used in the survey to collect data including demographic information，frequency of active access to maternal and child health information，the impact of Internet information，level of general maternal and child health knowledge/information，experience of learning in the school for pregnant women，ways to access to health information，ability of discriminating health information，interpersonal communication network for maternal and child health information，etc. Multivariate Logistic regression analysis was used to explore the influencing factors of discrimination ability in maternal and infant health information. Results　A total of 1 100 cases attended the survey，and 858（78.00%） of them who returned responsive questionnaires were included for analysis. Of the respondents，345（40.21%） had self-reported difficulty in discriminating maternal and infant health information. Multivariate Logistic regression analysis showed that higher ability in discriminating maternal health information was associated with strong health awareness〔OR=1.354，95%CI（1.015，1.805）〕，active access to maternal and infant health information〔OR=1.364，95%CI（1.073，1.733）〕，having general maternal and infant health knowledge/information〔OR=1.523，95%CI（1.106，2.097）〕，and large-scale maternal and infant health information exchange network〔OR=1.461，95%CI（1.092，1.955）〕（P<0.05）. Internet information was found to be related to decreased ability to discriminate maternal and child health information〔OR=0.509，95%CI（0.340，0.762），P<0.05〕. Conclusion　Our survey indicates that there may be still great space to improve the ability of discriminating health information in pregnant women. To improve the ability of them，it is essential to promote the publicity and education of general maternal and infant health information，motivate them to actively acquire such information，encourage them to seek extensive and professional social support，and strengthen the supervision of health information quality.

摘要： 背景　当前母婴健康信息呈爆炸式增长，但质量监管滞后，孕产妇对健康信息的辨别成为一大挑战。目的　探讨孕产妇母婴健康信息辨别能力及其影响因素。方法　选取2016年11月—2017年8月在山西省儿童医院、山西博爱医院和太原市晋源区金胜镇卫生院就诊的孕产妇实施调查。自行设计调查问卷，内容包括人口统计学信息、主动获取母婴健康信息频次、互联网信息的影响、是否具备基础性母婴健康知识/信息、有无在孕妇学校学习、健康信息获取途径、健康信息辨别能力、母婴健康信息人际交流网等。采用多因素Logistic回归分析探究孕产妇母婴健康信息辨别能力的影响因素。结果　共发放问卷1 100份，回收有效问卷858份，有效回收率为78.00%。345例（40.21%）孕产妇自感辨别母婴健康信息有困难。多因素Logistic回归分析结果显示，健康意识强〔OR=1.354，95%CI（1.015，1.805）〕、主动获取母婴健康信息〔OR=1.364，95%CI（1.073，1.733）〕、具备基础性母婴健康知识/信息〔OR=1.523，95%CI（1.106，2.097）〕、母婴健康信息交流网规模大〔OR=1.461，95%CI（1.092，1.955）〕的孕产妇健康信息辨别能力更强（P<0.05）。互联网信息的影响会降低孕产妇的母婴健康信息辨别能力〔OR=0.509，95%CI（0.340，0.762），P<0.05〕。结论　孕产妇的母婴健康信息辨别能力有很大的提升空间。加强母婴保健基础性知识/信息的宣传教育、孕产妇健康意识和信息获取动机的培养，鼓励孕产妇寻求广泛而专业的社会支持，强化对健康信息质量的监管，有利于提升孕产妇母婴健康信息辨别能力。
