A retrospective population-based case-control study of sexually transmitted urethritis was conducted at a large military base over a 21-month period. During the study, 9,514 patients were seen for sexually transmitted disease. The analysis was restricted to active duty males and showed that Blacks had 14.8 times the incidence rate of gonococcal urethritis (GCU) and 4.7 times the rate of nongonococcal urethritis (NGU) compared to Whites. There were slightly fewer cases of NGU than GCU. A case-control study of active duty soldiers showed that both Black and White circumcised subjects were 1.65 times as likely to have NGU as uncircumcised subjects (95% CI: 1.37-2.00). However, circumcision was not associated with an increased incidence of GCU.
在一个大型军事基地进行了一项为期21个月的基于人群的性传播尿道炎回顾性病例对照研究。研究期间,有9514名患者因性传播疾病前来就诊。分析仅限于现役男性,结果显示,与白人相比,黑人患淋菌性尿道炎(GCU)的发病率是白人的14.8倍,患非淋菌性尿道炎(NGU)的发病率是白人的4.7倍。NGU的病例略少于GCU。一项针对现役士兵的病例对照研究表明,无论是黑人还是白人,接受包皮环切术的受试者患NGU的可能性是未接受包皮环切术受试者的1.65倍(95%置信区间:1.37 - 2.00)。然而,包皮环切术与GCU发病率的增加无关。
