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 lifetime 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.
