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, >or=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.
