Objectives: To estimate the prevalence of chlamydia infection in young men in the Mid-Western Health Board Region of Ireland, and to determine risk factors for its acquisition. Methods: Consecutive men attending orthopaedic clinics (OP D), and a university sports arena (UL) were recruited to a chlamydia prevalence study. All men aged 17- 35 who had been sexually active and had not passed urin e in the last hour were eligible. Information about chlamydia was given, informe d consent obtained, and a self administered questionnairewas completed. A first void urine (FVU) was collected and tested by ligase chain reaction (LCR). Result s: 82% (207/252) of men from OPD, and 60% (186/310) from UL participated. 6. 3% (13/207) from the OPD and 5.4% (10/186) from UL tested LCR positive, givi ng an overall prevalence of 5.9% (23/ 393). Proved risk factors for chlamydial positivity were: (1) more than one sexual partner in previous 6 months, (2) mor e than eight lifetime sexual partners, (3) current symptoms (dysuria or discharg e)- . No statistical significance was found for age, condom use, smoking, days since last sexual intercourse and previous GUM clinic attendance. No statistical ly significant difference to cost effective prevalence of 6% was shown. Conclu sions: A 5.9% prevalence of Chlamydia trachomatis was found which is cost effe ctive to screen and treat. Non-invasive screening of men in the community was possible. Numbers of sexual partners and current symptoms were significant risk factors. Since only 25% of men in this laboratory were diagnosed with chlamydi a outside the GUM clinic, compared with 59% of women, it is important that com munity screening of men is promoted.
