The aim of this study was to determine the prevalence of Chlamydia trachomatis infection in undiagnosed young people aged between 15 and 24 years. Materials and Methods:A convenience sample of 623 youths, with a mean (SD) age of 20.1 (2.2) years, was recruited from key spaces in the North Metropolitan area of Barcelona in Catalonia, Spain. Participants completed a 21-item questionnaire and provided a urine sample or vaginal swab for testing. Results:The most common age at the first sexual intercourse was 16 years (24.6%), followed by 15 years (21.3%). Only 32.6% reported always use of condoms, 49.2% sometimes, and 15.6% never. A positive test for chlamydia was found in 34 participants (5.5%; 95% CI, 3.8-7.5), with no difference by sex. A positive test was significantly more common among the participants who were working, who had been diagnosed with a sexually transmitted disease (STD) at some point in their life, and who used web pages/apps to find new sexual partners more than once a month. In the multivariate analysis, working status was an independent factor associated with chlamydial infection (adjusted odds ratio[OR], 8.88; 95% CI, 1.71-46.17), whereas not having been previously diagnosed with an STD (OR, 0.34; 95% CI, 0.07-1.49) and never using the Internet to find sexual partners (OR, 0.16; 95% CI, 0.03-080) were protective factors against chlamydial infection. Conclusions:The prevalence of C. trachomatis infection was 5.5%.Working status, a previous diagnosis of STD, and use of the Internet to find new sexual partners were associated with chlamydial test positivity.

BACKGROUND Today's young people have long been demanding a paradigm shift in the emotional and sexual education they receive. While for them, affective-sexual and gender diversity is already a reality, the sexual and reproductive health professionals they encounter lack sufficient training. The digital devices and affective-sexual education websites aimed at today's young people must also be thoroughly evaluated. The website Sexe Joves is a website on sexuality of the Department of Health of the Government of Catalonia (Spain). It is designed for 14- to 25-year-olds. It currently needs to undergo a process of evaluation. Affective-sexual education aimed at young people must stem from their participation and the whole range of sexual and gender diversity in order to reach the entire population equally. OBJECTIVE The aim of this study was to evaluate the website Sexe Joves as a source of affective-sexual health information, education and communication for young people. It takes into account sex, gender identity, sexual orientation, socioeconomic status and location within Catalonia (urban, semiurban and rural areas). METHODS Observational, descriptive and cross-sectional study that forms part of a larger mixed methods study. An ad hoc questionnaire was used to collect data. In total, 1,830 participants were included. The study was carried out simultaneously in all the territorial administrations of Catalonia. RESULTS Almost 30% of the sample obtained were young people who experience affective-sexual and gender diversity. Of those surveyed, only 14.2% (n=260) said they were familiar with the website and of these, 6.5% said they used it (n=114). The website content rated most indispensable was sexual abuse, harassment and violence, followed by sexually transmitted infections. And 70.5% reported that they visit pornographic websites. CONCLUSIONS The results of this study will contribute to the design of new strategies for the website Sexe Joves, a public health resource, in order to improve affective-sexual education for young people.
