Risk factors for Ct infection were assessed in 6810 consecutive asymptomatic young women seeking contraceptive advice. All women filled in a questionnaire and were offered Ct testing.<\/jats:p>\n                  <jats:p>Of the 5785 who consented to testing, 425 (7.3%) were Ct culture positive. Four variables were significantly related to increased risk of being infected: age 18\u201323 years, duration of present relationship &lt; 1 year, non-use of condoms, and a history of not having had a previous genital infection.<\/jats:p>\n                  <jats:p>It is not possible to devise screening criteria that would effectively identify women at high risk. Therefore a screening programme should be targeted at all sexually active young people. However, if after some years the programme succeeds in lowering general Ct prevalence, these factors may be important when selecting patients for Ct testing.<\/jats:p>","DOI":"10.1177\/095646249200300208","type":"journal-article","created":{"date-parts":[[2017,1,11]],"date-time":"2017-01-11T17:38:58Z","timestamp":1484156338000},"page":"117-122","source":"Crossref","is-referenced-by-count":20,"title":["Risk Factors for\n                    <i>Chlamydia Trachomatis<\/i>\n                    Infection in 6810 Young Women Attending Family Planning Clinics"],"prefix":"10.1177","volume":"3","author":[{"given":"Kristina","family":"Ramstedt","sequence":"first","affiliation":[{"name":"University of G\u00f6teborg, Department of Dermato-Venereology, Sociala Huset, S-411 17 Gothenburg"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lars","family":"Forssman","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynaecology, \u00d6stra sjukhuset, 41685 Gothenburg"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Johan","family":"Giesecke","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, National Bacteriological Laboratory, Stockholm, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fredrik","family":"Granath","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, National Bacteriological Laboratory, Stockholm, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1992,3,1]]},"reference":[{"key":"bibr1-095646249200300208","unstructured":"Annual Reports of the National Bacteriological Laboratory, 1985\u20131989.
