In Sri Lanka little is known about the prevalence of Chlamydia trachomatis (CT) infection. Objective was to determine the prevalence of CT in female patients attending sexually transmitted disease (STD) clinics in the Colombo district.
A descriptive cross-sectional study was carried out for the prevalence of CT in all female patients (n = 168) more than 18 years of age, attending two STD clinics in the Colombo district from January to May 2012. Endocervical swabs were collected and tested for CT using the Amplicor CT/NG polymerase chain reaction assay.
Prevalence of CT in females attending the STD clinics in the Colombo district was 8.3%. Mean age of those infected with CT was 32.9 years (SD ± 8.2). Majority of females with CT infections were Sinhalese and married. There was no significant association with age, ethnicity or being married or not. Females who did not attend school, or had their education only up to Grade 5 were significantly found to have six times the risk of having CT infection (95% CI = 1.8-22.6). A significant association was found with number of sexual partners but not with commercial sex work or past history of STD.
Prevalence of CT was moderately high in this population.
在斯里兰卡，人们对沙眼衣原体（CT）感染的流行情况知之甚少。目的是确定科伦坡地区性传播疾病（STD）诊所女性患者中CT的流行率。
对2012年1月至5月在科伦坡地区两家STD诊所就诊的所有18岁以上女性患者（n = 168）进行CT流行率的描述性横断面研究。采集宫颈拭子，使用Amplicor CT/NG聚合酶链反应检测法检测CT。
科伦坡地区STD诊所女性患者中CT的流行率为8.3%。感染CT的女性平均年龄为32.9岁（标准差±8.2）。感染CT的女性多数为僧伽罗族且已婚。年龄、种族或婚姻状况与之无显著关联。未上学或仅接受过五年级教育的女性感染CT的风险显著高出六倍（95%置信区间 = 1.8 - 22.6）。性伴侣数量与之存在显著关联，但与商业性工作或既往STD病史无关。
该人群中CT的流行率中等偏高。
