Objective: To determine the prevalence of Chlamydia trachomatis (C. trachomatis) and Neisseria gonorrhoeae (N. gonhorroeae) infections and the risk factors for acquiring them in individuals under 35 years-old attending sexual health clinics in Barcelona province in 2006. Methods: Cross-sectional study of a convenience sample of 500 adolescents and young adults aged between 16 and 35 years. A total of 423 samples were analysed using real-time PCR. A standardised questionnaire was used to collect clinical, epidemiological, and behavioural data on the participants. Significant differences were analysed in the descriptive study using Pearson's (2. The association between C. trachomatis infection and its determining factors was analysed using the Mantel-Haenszel test and a multivariate logistic regression model. Results: The overall prevalence of C. trachomatis was 4%, and was significantly higher in those under 25 years of age. The overall prevalence of N. gonhorroeae was 0.2%. The independent risk factors for infection by C. trachomatis were as follows: foreign origin (OR: 3.74; CI 95%: 1.10-12.72), having had a sexual partner in the last 3 months (OR 3.91; CI 95%: 1.30-11.81), and tobacco use the last 12 months (OR: 4.99; CI 95%: 1.34-18.59). Conclusions: This is the first study performed in Catalonia that shows high prevalence of C. trachomatis in young people, thus confirming trends in the rest of Europe. Systematic monitoring of C. trachomatis infection in sentinel populations will provide valid information allowing us to assess the relevance of proposing targeted screening programs in our setting. © 2010 Elsevier España, S.L.
