对细菌性阴道病的４５例孕妇进行回顾性分析，用同期孕检１００例作对照。结果显示细菌性阴道病的早产率为４４．４％，明显高于对照组的５％（Ｐ＜０．０１）。发现发病时间、病程及菌种均与早产的发生有密切关系。认为孕妇合并细菌性阴道病可使早产率升高，加强产前检查，及时诊断和治疗细菌性阴道病可降低早产的发生 Forty-five pregnant women with bacterial vaginosis were retrospectively analyzed, and 100 pregnant women in the same period were used as controls. The results showed that the rate of bacterial vaginosis premature delivery was 44.4%, significantly higher than the control group of 5% (P <0.01). Found that the onset time, duration and species are closely related with the occurrence of preterm birth. That pregnant women with bacterial vaginosis can increase the rate of preterm birth, strengthen prenatal care, timely diagnosis and treatment of bacterial vaginosis can reduce the incidence of preterm birth
