【摘要】 目的 分析内蒙古地区孕妇B族链球菌（GBS）阳性率及危险因素。方法 选取2021年7月至2023年5月在内蒙古自治区妇幼保健院行孕期检查的9048名孕妇，均采用荧光定量聚合酶链反应法检测GBS感染情况，分析内蒙古地区孕妇GBS阳性率及危险因素。结果 9048名孕妇中，300名孕妇GBS检测阳性，GBS阳性率为3.32%。单因素分析结果显示，两组不良孕产史比较，差异有统计学意义（P<0.05）。多因素logistic回归分析结果显示，不良孕产史是孕妇GBS阳性的独立危险因素（P <0.05）。结论 内蒙古地区孕妇GBS阳性率较低；不良孕产史是孕妇GBS感染的危险因素，临床应积极对危险因素采取针对性预防对策，以降低围生期新生儿GBS感染的发生风险。更多还原

【Abstract】 Objective To analyze the positive rate and risk factors of group B Streptococcus(GBS) in pregnant women in Inner Mongolia Region. Methods A total of 9048 pregnant women who underwent pregnancy examination in the Maternal and Child Health Hospital of Inner Mongolia Autonomous Region from July 2021 to May 2023 were selected. GBS infection was detected by fluorescence quantitative polymerase chain reaction, and the positive rate of GBS and risk factors of pregnant women in Inner Mongolia Region were analyzed. Results Among the 9048 pregnant women, 300 pregnant women were GBS positive, and the GBS positive rate was 3.32%. Univariate analysis showed that there was a statistically significant difference in the history of adverse pregnancy and childbirth between the two groups(P < 0.05). Multivariate logistic regression analysis showed that history of adverse pregnancy and childbirth was an independent risk factor for GBS infection in pregnant women(P < 0.05). Conclusion The positive rate of GBS in pregnant women in Inner Mongolia Region is low. History of adverse pregnancy and childbirth is a risk factor for GBS infection in pregnant women, and targeted preventive measures should be taken to reduce the risk of neonatal GBS infection during the perinatal period.更多还原
