Abstract

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.
