CHLAMYDIA CONTROL PLAN--STAGE 1

这项研究是全州范围衣原体预防和控制计划的第一阶段。这项研究是对北卡罗来纳州选定县的妇女衣原体流行率的横断面、基于临床的调查。所选择的县在地理上是多样化的，有城乡代表性，并有足够的工作人员来便利调查。目标人群是生活在北卡罗来纳州类似地区的妇女。研究人群将包括在选定县的县卫生局性病和计划生育诊所就诊的有症状和无症状的妇女。所有在这些诊所接受盆腔检查的女性都有资格参加。参与的内容包括危险标记物和危险行为的问卷调查、盆腔检查以及通过连接酶链式反应筛查衣原体感染。在某些情况下，还将使用酶免疫分析进行筛查。将使用这些检测结果来确定参加临床诊所的妇女中有症状和无症状感染的流行率。将确定在未来预防方案中使用的筛查标准。

This study is the first stage of a statewide chlamydia prevention and control program. The study is a cross-section, clinic-based investigation of the prevalence of chlamydia among women in selected counties in North Carolina. Counties are selected to be geographically diverse, with representation of urban and rural areas, and with sufficient staffing to facilitate the investigation. The target population is women living within similar areas of North Carolina. The study population wil include symptomatic and asymptomatic women attending the County Health Department STD and Family Planning Clinics in the selected counties. All women udnergoing pelvic examination in these clincis will be eligible for participation. Participation will involve a questionnaire of risk markers and risk behaviors, pelvic examination, and screening for chlamydial infection by ligase chain reaction assay. In some cases, enzyme immune assay will also be used for screening. Prevalence of symptomatic and asymptomatic infection among women attending the clincs will be determined using these test results. Identification of screening criteria to be used in future prevention programs will be developed.
