We aim to describe recent trends in STIs among adolescents and to analyse their socio-demographic and behavioural characteristics in Catalonia, Spain between 2012 and 2017. Data on Chlamydia trachomatis (CT) infection, gonorrhoea and syphilis cases aged from 13 to 19\u2009years reported to the Catalan Mandatory Notifiable System from 2012 to 2017 were analysed. Diagnosis rates were calculated and a descriptive analysis was performed. Between 2012 and 2017, CT infection, gonorrhoea and syphilis cases reported among adolescents aged 13\u201319\u2009years accounted for more than one-eleventh of all reported cases in Catalonia. The rate of the three nationally-notifiable STIs increased dramatically among adolescents. CT infection rates rose from 13 to 144.1 per 100,000 adolescents between 2012 and 2017, an increase of 1007%; gonorrhoea cases increased by 246% (from 13.4 to 45.4\/100,000) and syphilis cases increased by 247% (from 1.7 to 5.9\/100,000). Gonorrhoea and syphilis cases affected mainly males while CT infection cases were mostly in females (84%). Adolescents are being increasingly affected by CT infection, gonorrhoea and syphilis. A broader array of intervention strategies aimed at adolescents should be reinforced through strong prevention campaigns, improved sexual health information, as well as encouragement of regular offers of STI screening by healthcare providers.<\/jats:p>","DOI":"10.1177\/0956462420940911","type":"journal-article","created":{"date-parts":[[2020,8,5]],"date-time":"2020-08-05T02:44:28Z","timestamp":1596595468000},"page":"1047-1054","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Recent trends in sexually transmitted infections among adolescents, Catalonia, Spain, 2012\u20132017"],"prefix":"10.1177","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5490-6110","authenticated-orcid":false,"given":"N","family":"Vives","sequence":"first","affiliation":[{"name":"Centre for Epidemiological Studies on STI\/HIV\/AIDS in Catalonia (CEEISCAT), Health Departament, Generalitat of Catalonia, Badalona, Spain"},{"name":"Cancer Screening Unit, Catalan Institute of Oncology, Hospitalet de Llobregat, Spain"},{"name":"CIBER Epidemiologia y Salud P\u00fablica (CIBERESP), Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P","family":"Garcia de Olalla","sequence":"additional","affiliation":[{"name":"CIBER Epidemiologia y Salud P\u00fablica (CIBERESP), Madrid, Spain"},{"name":"Epidemiological Service of Public Health Agency of Barcelona, Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"V","family":"Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Centre for Epidemiological Studies on STI\/HIV\/AIDS in Catalonia (CEEISCAT), Health Departament, Generalitat of Catalonia, Badalona, Spain"},{"name":"CIBER Epidemiologia y Salud P\u00fablica (CIBERESP), Madrid, Spain"},{"name":"Institute for Health Science Research Germans Trias i Pujol (IGTP), Badalona, Spain"},{"name":"Microbiology Service, Hospital Universitari Germans Trias i Pujol, Badalona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I","family":"Barrabeig","sequence":"additional","affiliation":[{"name":"CIBER Epidemiologia y Salud P\u00fablica (CIBERESP), Madrid, Spain"},{"name":"Epidemiological Surveillance and Response to Public Health Emergencies Service in Barcelona South, Agency of Public Health of Catalonia, Generalitat of Catalonia, Hospitalet del Llobregat, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L","family":"Clotet","sequence":"additional","affiliation":[{"name":"Epidemiological Surveillance and Response to Public Health Emergencies Service in Vall\u00e8s Occidental and Vall\u00e8s Oriental, Agency of Public Health of Catalonia, Generalitat of Catalonia, Sant Cugat del Vall\u00e8s, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M","family":"Dan\u00e9s","sequence":"additional","affiliation":[{"name":"Epidemiological Surveillance and Response to Public Health Emergencies Service in Girona, Agency of Public Health of Catalonia, Generalitat of Catalonia, Girona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N","family":"Borrell","sequence":"additional","affiliation":[{"name":"Epidemiological Surveillance and Response to Public Health Emergencies Service in Tarragona Camp, Agency of Public Health of Catalonia, Generalitat of Catalonia, Tarragona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J","family":"Casabona","sequence":"additional","affiliation":[{"name":"Centre for Epidemiological Studies on STI\/HIV\/AIDS in Catalonia (CEEISCAT), Health Departament, Generalitat of Catalonia, Badalona, Spain"},{"name":"CIBER Epidemiologia y Salud P\u00fablica (CIBERESP), Madrid, Spain"},{"name":"Institute for Health Science Research Germans Trias i Pujol (IGTP), Badalona, Spain"},{"name":"Department of Paediatrics, Obstetrics, Gynaecology and Preventive Medicine, Universitat Aut\u00f2noma de Barcelona (UAB), Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"the Catalan HIV and STI Surveillance Group","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,8,4]]},"reference":[{"key":"bibr1-0956462420940911","doi-asserted-by":"publisher","DOI":"10.1016\/j.yhbeh.2013.03.006"},{"key":"bibr2-0956462420940911","doi-asserted-by":"publisher","DOI":"10.1016\/j.adolescence.2014.03.009"},{"key":"bibr3-0956462420940911","doi-asserted-by":"publisher","DOI":"10.1016\/j.jadohealth.2017.07.004"},{"key":"bibr4-0956462420940911","unstructured":"Resumen Ejecutivo de la Encuesta Nacional de Salud Sexual (2009).
