To explore the risk factors for nausea and vomiting in pregnant women. Methods: Using cluster random sampling method and following the exclusion and inclusion criteria, a total of 713 pregnant women from the health service center of 3 street communities in Changsha city district were enrolled. Statistical analysis was used to analyze the relevant influential factors for nausea and vomiting. Results: Vomiting incidence in pregnant women was 59.6%. The risk factors for nausea and vomiting were female fetus (OR=1.404, 95% CI 1.035 to 1.905), vaginal bleeding (OR=1.513, 95%CI 1.062 to 2.156) and life stress (OR=1.031, 95% CI 1.009 to 1.054), and the protective factor for nausea and vomiting was the age (OR=0.798, 95% CI 0.661 to 0.964). Conclusion: The pregnant vomiting is a result of a combination of multiple factors. Age, female fetus, vaginal bleeding, negative quality of life are the influential factors for vomiting during pregnancy. Prenatal health education should be strengthened for young pregnant women. Suitable maintenance for pregnant woman life should be performed to reduce the amount of negative stimulus.
目的：探讨妊娠呕吐的相关影响因素。方法：采用整群随机抽样方法，根据排除与纳入标准，收集湖南省长沙市某区3 个街道社区卫生服务中心713例孕妇资料，回顾性收集其孕前、孕期和分娩情况，运用t检验、χ2检验和logistic回归分析孕妇呕吐的相关影响因素。结果：该区妊娠呕吐发生率为59.6%。多因素非条件logistic回归分析结果显示：女胎(OR=1.404，95%CI：1.035~1.905)、有阴道流血经历(OR=1.513，95%CI：1.062~2.156)和负性生活刺激量(OR=1.031，95%CI：1.009~1.054)是妊娠呕吐的危险因素，年龄是妊娠呕吐的保护因素(OR=0.798，95%CI：0.661~0.964)。结论：妊娠呕吐是多因素综合作用的结果，年龄、女胎、有阴道流血经历、负性生活刺激量是妊娠期呕吐的影响因素，应加强对较年轻孕妇的产前健康教育，对应激量较高孕妇的生活进行合适的维护，减少其负性生活刺激量。.
