Participants completed a questionnaire and gave urine samples which were screened for <jats:italic>C. trachomatis<\/jats:italic> DNA by PCR.

Although frequent, neither unprotected sex (absence of condom use), nor alcohol and drug abuse were associated with chlamydial infection. Men living in cities were more frequently infected (2.9%, 95%CI 0.8\u20137.4%) than men living in rural areas (0.5%, 95%CI 0.1\u20131.9%, p = 0.046). Moreover, naturalised Swiss citizens were more often positive (4.9%, 95%CI 1.3\u201312.5%) than native-born Swiss men (0.5%, 95%CI 0.1\u20131.7%, p = 0.003).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>In comparison with other countries, the prevalence of chlamydial infection in men is extremely low in Switzerland, despite a significant prevalence of risky sexual behaviour. <jats:italic>C. trachomatis<\/jats:italic> infection was especially prevalent in men with multiple sexual partners. Further research is required (i) to define which subgroup of the general population should be routinely screened, and (ii) to test whether such a targeted screening strategy will be effective to reduce the prevalence of chlamydial infection among this population.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1186\/1471-2334-8-45","type":"journal-article","created":{"date-parts":[[2008,4,15]],"date-time":"2008-04-15T06:13:44Z","timestamp":1208240024000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Low prevalence of Chlamydia trachomatisinfection in asymptomatic young Swiss men"],"prefix":"10.1186","volume":"8","author":[{"given":"David","family":"Baud","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katia","family":"Jaton","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claire","family":"Bertelli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean-Pierre","family":"Kulling","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gilbert","family":"Greub","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2008,4,12]]},"reference":[{"key":"636_CR1","doi-asserted-by":"publisher","first-page":"941","DOI":"10.1016\/j.bpobgyn.2006.06.003","volume":"20","author":"K Manavi","year":"2006","unstructured":"Manavi K: A review on infection with Chlamydia trachomatis.
