Sexual behavior survey and screening for chlamydia and gonorrhea in university students in South Korea

Background: The purpose of the present study was to define the prevalence of genital Chlamydia trachomatis and Neisseria gonorrhoeae infections and status of sexual risk behavior among university students (18-25 years old) in the capital region of South Korea. Methods: Participants filled out a self-administered questionnaire related to sexuality. First-void urine was analyzed for chlamydial and gonococcal infection by strand displacement amplification (BDProbTecET, BD Diagnostic Systems, MD). Results: A total of 622 students from 15 colleges in three universities took part in the study. The median age was 21 and 39.1% of them reported having sexual intercourse at least once. The prevalence of C. trachomatis among sexually active men and women was 8.4% and 10.6%, respectively. Gonococcal infection was noted in one symptomatic male. Factors significantly associated with infection were the number of sexual partners during past year and lifetime and condom use. Conclusions: This is the first sexually transmitted infection (STI) screening in university students in South Korea. Urine-based STI screening was both feasible and acceptable in university students in South Korea. It should be considered a routine part of programs to control STI nationally.
