Chlamydia trachomatis is a common cause of sexually transmitted disease in adolescent girls. Of 366 adolescent patients screened, 15.3% were found to have chlamydial endocervical infections, with an infection rate of 23.3% in blacks, 14.3% in Hispanics, and 10.3% in whites (P = 0.01, excess for blacks). Of Chlamydia-positive patients, 63.6% had a diagnosis of lower genital tract infection, compared with 35.4% of Chlamydia-negative patients (P = 0.004). Oral contraceptive users had a higher prevalence of infection (23.8%) compared with those using a barrier method (16.2%) or with nonusers (9.3%) (P = 0.004). Inflammatory changes on Papanicolaou smears were associated with chlamydial infection (P = 0.0001). Other variables identified as risk factors for chlamydial infection included both a younger age at first intercourse (P = 0.02) and more years of sexual activity (P = 0.02). Chronologic, menarchal, and gynecologic age, biologic age of the cervix, the number of sexual partners in the last month and during a lifetime, and parity were not found to be associated with recovery of Chlamydia.
沙眼衣原体是青春期女孩性传播疾病的常见病因。在366名接受筛查的青春期患者中，15.3%被发现患有衣原体宫颈感染，黑人的感染率为23.3%，西班牙裔为14.3%，白人为10.3%（P = 0.01，黑人感染率过高）。在衣原体阳性患者中，63.6%被诊断为下生殖道感染，而衣原体阴性患者的这一比例为35.4%（P = 0.004）。口服避孕药使用者的感染率（23.8%）高于使用屏障避孕法者（16.2%）或未使用者（9.3%）（P = 0.004）。巴氏涂片上的炎症变化与衣原体感染相关（P = 0.0001）。其他被确定为衣原体感染危险因素的变量包括首次性交年龄较小（P = 0.02）和性活动年限较长（P = 0.02）。未发现按时间顺序计算的年龄、初潮年龄、妇科年龄、宫颈生物学年龄、过去一个月和一生中的性伴侣数量以及产次与衣原体的检出有关。
