The prevalence of Chlamydia trachomatis genital infection was studied in a sexually active urban Baltimore adolescent population. Possible risk factors such as age, past history of sexually transmitted disease, number of sexual partners, contact with sexually transmitted disease, oral contraceptive use, and concomitant gonococcal infection were also evaluated. The prevalence of chlamydial infection in the 280 adolescents studied was 26%: 35% in male adolescents, 27% in pregnant female adolescents, and 23% in nonpregnant female adolescents. Chlamydia was almost three times as prevalent as gonorrhea in the same population. Age, past history of sexually transmitted disease, oral contraceptive use, and concomitant gonorrhea were not significantly associated with chlamydial infection. However, multiple current sexual partners, contact with sexually transmitted disease, genitourinary symptoms, and cervical ectopy were significantly associated with chlamydial infection. Testing for chlamydial infection in sexually active urban teenagers is recommended for those with genitourinary symptoms, those with cervical ectopy, or those who are contacts of persons with sexually transmitted disease. Considering the reservoir of infection in the asymptomatic female adolescents, screening for chlamydial infections in family planning clinics warrants consideration.
在巴尔的摩市区有性活动的青少年人群中，研究了沙眼衣原体生殖道感染的患病率。还评估了可能的危险因素，如年龄、性传播疾病既往史、性伴侣数量、接触性传播疾病情况、口服避孕药使用情况以及合并淋球菌感染情况。在研究的280名青少年中，衣原体感染患病率为26%：男性青少年为35%，怀孕女性青少年为27%，未怀孕女性青少年为23%。在同一人群中，衣原体感染率几乎是淋病感染率的三倍。年龄、性传播疾病既往史、口服避孕药使用情况以及合并淋病与衣原体感染无显著关联。然而，当前有多个性伴侣、接触性传播疾病、泌尿生殖系统症状以及宫颈外翻与衣原体感染显著相关。对于有泌尿生殖系统症状、宫颈外翻或接触性传播疾病患者的有性活动的市区青少年，建议进行衣原体感染检测。考虑到无症状女性青少年中的感染源，在计划生育诊所筛查衣原体感染值得考虑。
