Chlamydia trachomatis among young Norwegian men:: Sexual behavior and genitourinary symptoms

Objective: The study objective was to assess Chlamydia trachomatis (CT) prevalence, risk factors, and genitourinary symptoms among young men. Methods: Sexually active men 18 to 30 years old were recruited during April through October 2005 at the student health services and through field work at university campuses in 2 Norwegian cities. A total of 1,032 participants completed a questionnaire on sexual behavior and provided first-void urine for CT testing. Results: The overall CT prevalence was 7.8% (81 of 1,032). In multivariable analysis, >= 5 tifetirne sexual partners (adjusted odds ratio [aOR]: 2.7,95% confidence interval [CI]: 1.4-5.2), a burning sensation on urination (aOR: 5.7, 95 % CI: 3.1-10.5), and penile discharge (aOR: 2.6, 95% CI: 1.1-6.3) were significant risk factors for a positive CT test, whereas condom use (last intercourse) was preventive (aOR: 0.4, 95 % CI: 0.2-0.8). Conclusions: A CT prevalence of 7.8% was found among male students. Promotion of increased testing among men is important to prevent CT transmission.
