To determine some epidemiological features of female sexually transmitted disease (STD) clinic attendees with Trichomonas vaginalis infection.
A retrospective audit of patient charts was performed on all cases of T. vaginalis infection diagnosed in female patients in an 18-month period from January 1998 to June 1999 (n=88). Descriptive features of these cases were collated. The ethnicity of female patients with T. vaginalis was compared to that of all other female attendees within the same period.
The incidence of T. vaginalis infection was 2.2% in 1998 1999. The mean age of patients was 26.5 years. Maori and Polynesian women were over-represented. Overall, patients were more likely to be symptomatic at presentation (78%) and to have abnormal findings on clinical examination (81%). 28% had co-existing chlamydia infection and 10% had co-existing gonorrhoea infection.
The mean age of 26.5 years is lower than that quoted in other studies. The majority of patients had more than one condition at diagnosis. The rate of co-infection with chlamydia is high and some consideration could be given to empirical treatment of chlamydia in patients diagnosed with T. vaginalis infection.
确定女性性传播疾病（STD）门诊中感染阴道毛滴虫患者的一些流行病学特征。
对1998年1月至1999年6月这18个月期间诊断为阴道毛滴虫感染的所有女性患者病历进行回顾性审核（n = 88）。整理这些病例的描述性特征。将感染阴道毛滴虫的女性患者的种族与同期所有其他女性就诊者的种族进行比较。
1998 - 1999年阴道毛滴虫感染发病率为2.2%。患者平均年龄为26.5岁。毛利族和波利尼西亚族女性占比过高。总体而言，患者就诊时更可能有症状（78%），临床检查有异常发现（81%）。28%合并衣原体感染，10%合并淋病感染。
26.5岁的平均年龄低于其他研究报告的年龄。大多数患者在诊断时有不止一种病症。衣原体合并感染率高，对于诊断为阴道毛滴虫感染的患者，可考虑对衣原体进行经验性治疗。
