Trichomonas vaginalis infection (TVI) was found by examination of Pap smears in 25% of 3,005 unselected urban black women being screened for cancer of the cervix and vagina. The incidence was 22% in the group under 29 years of age; 69% in those between 30 and 59; and 9% in those over 60. Women who had had a hysterectomy had 16% lower incidence of TVI than did the controls. Class 1 reports (atypia, metaplasia, hyperplasia) were obtained in 10% of the entire group. Cytologic changes were present in 19% of the women with TVI. Women who had had hysterectomy had a 40% less chance of having a class 1 report compared with controls. Class 1 reports occurred 2.7 times more frequently in TVI than in uninfected controls.
在对3005名未经过挑选的城市黑人女性进行宫颈癌和阴道癌筛查时,通过巴氏涂片检查发现,25%的女性感染了阴道毛滴虫。29岁以下组的感染率为22%;30至59岁组为69%;60岁以上组为9%。接受子宫切除术的女性阴道毛滴虫感染率比对照组低16%。整个组中有10%的人获得了1级报告(非典型性、化生、增生)。19%感染阴道毛滴虫的女性存在细胞学变化。与对照组相比,接受子宫切除术的女性获得1级报告的可能性要低40%。1级报告在感染阴道毛滴虫的女性中出现的频率是未感染对照组的2.7倍。
