The frequency of genital infection was compared among women in premature labor who delivered preterm (before 37 weeks), women in preterm labor who delivered at term, and control women who delivered at term. Both groups of women in premature labor were younger and had more previous preterm births than did control women. Women in premature labor who delivered preterm were more likely to experience rupture of membranes, intrapartum fever, and postpartum fever than were control women. The presence of bacterial vaginosis (odds ratio 2.3) and Chlamydia trachomatis (odds ratio 3.9) was positively associated, and Lactobacillus sp (odds ratio 0.2) was negatively associated, with birth before 37 weeks, using multivariable analysis to control for confounding variables.
对早产（孕周小于37周）并早产分娩的女性、早产但足月分娩的女性以及足月分娩的对照女性的生殖道感染频率进行了比较。两组早产女性均比对照女性更年轻且既往早产次数更多。早产并早产分娩的女性比对照女性更易出现胎膜破裂、产时发热和产后发热。采用多变量分析控制混杂变量后，细菌性阴道病（优势比2.3）和沙眼衣原体（优势比3.9）与37周前分娩呈正相关，而乳酸杆菌属（优势比0.2）与37周前分娩呈负相关。
