Chlamydia (Chlamydia trachomatis) is the most commonly diagnosed sexually transmissible infection (STI) in Singapore, with rising incidence.
Random sampling was performed on all chlamydia-positive samples collected from female patients who attended a women's clinic from January 2010 to December 2010. Some 250 electronic medical records were analysed. Population demographics, sexual histories, symptoms, diagnostic methods and management were recorded.
One hundred and forty-two (56.8%) patients were under 25 years of age. The predominant race diagnosed with Chlamydia cervicitis were Chinese (116 cases, 46.4%) followed by 86 (34.4%) Malays and 20 (8%) Filipinos. Sixty-three (25.2%) were skilled workers and (47) 18.8% were students. Professionals and office workers together formed 68 (27.2%) of the patients. Some 248 (99.2%) patients were heterosexual and 2 (0.8%) patients were bisexual; 229 (91.6%) patients had regular partners, 18 (7.2%) had casual partners and 3 (1.2%) had both. Concurrency prevalence accounted for 49 cases (19.6%) and condom use was less common. Patients were generally asymptomatic, with 114 (45.5%) presenting with symptoms. One hundred and eight (43.2%) patients had 2-5 sexual partners in their lifetime. Patients with a termination made up 12% of our cohort. This episode of infection was the first diagnosis of an STI for 198 (79.2%) patients; 24 (9.6%) of patients had been previously diagnosed with chlamydia.
Chlamydia infection was most prevalent in skilled workers and their regular partners with heterosexual practices under 25 years old. Most patients had 2-5 sexual partners and did not use condoms consistently or at all.
衣原体（沙眼衣原体）是新加坡诊断最为常见的性传播感染（STI），其发病率呈上升趋势。
对2010年1月至2010年12月期间在一家妇科诊所就诊的女性患者所采集的所有衣原体阳性样本进行随机抽样。分析了约250份电子病历。记录了人口统计学特征、性病史、症状、诊断方法及治疗情况。
142名（56.8%）患者年龄在25岁以下。被诊断为衣原体宫颈炎的主要种族为华人（116例，46.4%），其次是马来人86例（34.4%）和菲律宾人20例（8%）。63名（25.2%）为技术工人，47名（18.8%）为学生。专业人员和办公室职员共占患者总数的68名（27.2%）。约248名（99.2%）患者为异性恋，2名（0.8%）患者为双性恋；229名（91.6%）患者有固定性伴侣，18名（7.2%）有临时性伴侣，3名（1.2%）两者皆有。同时感染率占49例（19.6%），避孕套使用不太普遍。患者通常无症状，114名（45.5%）有症状表现。108名（43.2%）患者一生中有2 - 5个性伴侣。有过终止妊娠史的患者占我们队列的12%。本次感染是198名（79.2%）患者首次被诊断为性传播感染；24名（9.6%）患者此前曾被诊断为衣原体感染。
衣原体感染在25岁以下有异性性行为的技术工人及其固定性伴侣中最为普遍。大多数患者有2 - 5个性伴侣，且未始终或根本不使用避孕套。
