Screening programmes are important for the control of Chlamydia trachomatis (Ct) infection, a disease spread mainly by asymptomatic carriers. Risk factors for Ct infection were assessed in 6810 consecutive asymptomatic young women seeking contraceptive advice. All women filled in a questionnaire and were offered Ct testing. Of the 5785 who consented to testing, 425 (7.3%) were Ct culture positive. Four variables were significantly related to increased risk of being infected: age 18-23 years, duration of present relationship less than 1 year, non-use of condoms, and a history of not having had a previous genital infection. It is not possible to devise screening criteria that would effectively identify women at high risk. Therefore a screening programme should be targeted at all sexually active young people. However, if after some years the programme succeeds in lowering general Ct prevalence, these factors may be important when selecting patients for Ct testing.
筛查项目对于控制沙眼衣原体（Ct）感染至关重要，沙眼衣原体感染是一种主要由无症状携带者传播的疾病。对连续6810名寻求避孕建议的无症状年轻女性评估了Ct感染的危险因素。所有女性都填写了问卷并接受了Ct检测。在同意检测的5785名女性中，425名（7.3%）Ct培养呈阳性。有四个变量与感染风险增加显著相关：年龄在18至23岁之间、当前恋爱关系持续时间少于1年、不使用安全套以及既往无生殖器感染史。制定能有效识别高危女性的筛查标准是不可能的。因此，筛查项目应针对所有性活跃的年轻人。然而，如果几年后该项目成功降低了总体Ct流行率，那么在选择进行Ct检测的患者时，这些因素可能会很重要。
