摘要 目的:分析医院孕晚期孕妇无乳链球菌(Streptococcus agalactiae,SA)感染的危险因素及其与新生儿早发感染的相关性。方法:选取医院2016年1月—2020年7月在医院开展孕期检查的孕晚期(31~40周)孕妇1 382例病历资料,统计其阴道及直肠拭子的SA培养、分离、鉴定结果,并按是否感染SA将其分为感染组和未感染组,分析其孕晚期孕妇的SA感染率、孕妇阴道拭子和直肠拭子SA检测的阳性率,以及与新生儿SA感染的相关因素,及感染组和未感染组新生儿不良结局的差异。结果:1 382例孕晚期孕妇标本中检出SA感染108例(占7.81%)为感染组,未感染1 274例(占92.19%)为未感染组;新生儿SA感染15例,其中7例母亲检出SA感染,垂直传播率为6.48%,其余8例母亲未检出SA感染,但发生早发型无乳链球菌疾病(Group B streptococcal early-onset disease,GBS-EOD)的1例,发病率为0.69‰;经单因素和多因素Logistic回归分析结果显示,患者年龄、体质量指数(BMI)、有流产史与孕晚期孕妇SA感染具有相关性(P<0.05),即为独立危险因素;感染组新生儿肺炎、窒息、胎儿窘迫的总发生率均高于未感染组(P<0.05)。结论:孕晚期孕妇SA感染风险、母婴垂直传播率和新生儿GBS-EOD发病率均较高,有必要对其开展SA产前筛查及相关治疗;孕妇年龄、BMI、有流产史是SA感染的独立危险因素,建议对孕晚期孕妇开展健康宣教,以减少SA感染发生,改善母-婴结局。
