title: [Prevalence of genital chlamydia trachomatis infections in college students.].
abstract: Sexually transmitted Chlamydia infection is the most common venereal disease in Iceland. Although considerable information is available on the epidemiology of these infections, the true prevalence of C. trachomatis infections in Iceland is unknown because all the studies have been conducted on selected populations. The purpose of the present study was twofold: To investigate the prevalence of Chlamydia infection in an unselected group of people in the age group at high risk, and to investigate the usefulness of collecting urine samples from college students as a screening method for Chlamydia. All students, aged 18-21, in the senior classes in a college in Reykjavik were requested to submit a first void urine (FVU) specimen taken in the morning and asked to fill out a short questionnaire. The urine samples were tested with a polymerase chain reaction assay, the Amplicor(R) PCR. One hundred eighty three students received urine collection kits. One hundred sixty (87.4%) delivered specimens. Seventy three males and 110 females received the containers. Sixty males (82%) and 100 (91%) females returned the samples. Three samples turned out to be positive (2%), all of them from females. For those who were sexually active (one or more partners for the last six months) the prevalence was 2.6% (117/160).
  
  
  CONCLUSIONS
  The prevalence of asymptomatic Chlamydia infection in college students in this school was low, probably too low for screening to be cost effective. The procedure was not satisfactory because of the low percentage that enquired about their tests. It is therefore unsuitable in a screening program.
