目的 了解孕产妇新型冠状病毒肺炎(简称新冠肺炎)相关知识知晓及行为状况，为进一步开展孕产妇健康教育和促进工作提供依据。方法 自行设计调查问卷，采取方便抽样的方法，于 2020 年 2 月 27 日至 3 月 6 日利用母子健康 App 对1 014 名孕产妇用户进行网络问卷调查，对孕产妇新冠肺炎防护知识知晓情况以及知识获取途径等进行分析。结果 孕产妇新冠肺炎预防相关知识总知晓率为 87. 7%,94. 8% 的孕产妇认为新冠肺炎会人传人，95. 3% 的孕产妇认为预防新冠病毒感染应经常开窗通风，部分孕产妇认为盐水漱口液(24. 8%)、吃大蒜(15. 8%)是预防新冠肺炎的有效措施。初产妇新冠肺炎防护知识知晓率为 89. 9%，高于经产妇(83. 8%)，差异有统计学意义(χ²= 47. 971,P < 0. 05)。孕产妇主要通过医务人员宣传(59. 1%)、网络及社交平台(47. 0%)、广播电视(39. 1%)等方式获取新冠肺炎预防相关知识，同时通过 3 种及以上途径获取相关预防知识的有 36. 0%。孕产妇主要采取的预防措施有外出时戴口罩(92. 8%)、经常洗手(88. 8%)、绝大多数时间居家(88. 0%)，初产妇同时采取这 3 种措施的比例高于经产妇，差异有统计学意义(χ²= 6. 283,P = 0. 012)。结论 孕产妇具备较好的新冠肺炎预防知识和防护能力，但仍存在一些误区，需要多途径开展宣传，尤其要充分发挥医务人员的作用，并加大对经产妇的宣传和管理力度。

Objective To investigate knowledge and practices of Corona Virus Disease 2019(COVID-19) prevention among pregnant women,so as to provide evidence for further health education and promotion.Methods Convenient sampling was used to recruit 1 014 pregnant women as study subjects from February 27^thto March 6^th2020. Self-designed internet-based online questionnaire survey was conducted through Healthy Family App. The knowledge and practices of COVID-19 as well as the information accessing was analyzed.Results The overall awareness rate of COVID-19 prevention was 87. 7%. And 94. 8% of the respondents indicated that the virus could be transmitted from human to human,and 95. 3% agreed that keeping windows open and ventilated was helpful for COVID-19prevention. However,some of them considered saltwater mouthwash(24. 8%)and garlic(15. 8%)were effective measures to prevent COVID-19. The awareness rate of COVID-19 prevention among primipara(89. 9%)was higher than that among parturient(83. 8%),and the difference was statistically significant(χ²= 47. 971,P < 0. 05). Pregnant women mainly accessed information of COVID-19prevention through medical staff(59. 1%),internet and social media platform(47. 0%),radio and/or television(39. 1%). 36. 0%respondents received information through three or more ways. The main preventive measures taken by pregnant women were wearing face masks outside(92. 8%),washing hands frequently(88. 8%)and staying indoor most of the time(88. 0%). The proportion of primipara taking these three measures concurrently was higher than that of primipara(χ²= 6. 283,P = 0. 012).Conclusion Pregnant women have good understandings and protection ability of COVID-19 prevention. However,misunderstandings still exist. It’s necessary to carry out advocacy campaign through a variety of channels,especially to give full play to the role of medical personnel,as well as to strengthen the advocacy and management of parturient.
