Studying their knowledge concerning sexuality and their main counsellors, can be an important step in targeting an updated health promotion approach. This study characterized adolescents and young adults\u2019 knowledge and attitudes about sexually transmitted diseases (STDs), and contraception, prospecting for their main trusted counseling sources. We conducted a cross-sectional, population-based, self-report survey of 746 individuals aged between 14 and 24 years from Paredes, Portugal. The questionnaire included many dimensions, as demographic characteristics, youth behavior, currently sexually active status, main counselors concerning health topics, awareness, and knowledge about STDs and contraception. Mean age of the participants was 18.3 years, 50.5% of them had started their sexual activity. Males present themselves as more sexually active, starting earlier, and have more sexual partners than females. Participants reported an adequate knowledge perception about STDs and contraception methods, however we found different patterns on specific STDs and contraceptive methods, according to gender, age, and sexually active status. Our results help design specific interventions to reach youth, community, and healthcare providers, pointing out the value of bringing people to the center of health policies.<\/jats:p>","DOI":"10.3390\/ijerph192113933","type":"journal-article","created":{"date-parts":[[2022,10,26]],"date-time":"2022-10-26T09:59:37Z","timestamp":1666778377000},"page":"13933","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Young People Awareness of Sexually Transmitted Diseases and Contraception: A Portuguese Population-Based Cross-Sectional Study"],"prefix":"10.3390","volume":"19","author":[{"given":"Carlos Franclim","family":"Silva","sequence":"first","affiliation":[{"name":"Department of Community Medicine, Information and Health Decision Sciences, Faculty of Medicine, University of Porto, Alameda Hernani Monteiro, 4200-319 Porto, Portugal"},{"name":"CINTESIS@RISE, MEDCIDS, Faculty of Medicine, University of Porto, Alameda Hernani Monteiro, 4200-319 Porto, Portugal"}]},{"given":"In\u00eas","family":"Silva","sequence":"additional","affiliation":[{"name":"Unidade de Sa\u00fade Familiar S\u00e3o Jo\u00e3o do Porto, Rua Miguel Bombarda, 234, 4050-377 Porto, Portugal"}]},{"given":"Alexandra","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"Servi\u00e7o de Dermatologia do Centro Hospitalar e Universit\u00e1rio do Porto, Largo do Prof. Abel Salazar, 4099-001 Porto, Portugal"}]},{"given":"Lu\u00edsa","family":"S\u00e1","sequence":"additional","affiliation":[{"name":"Department of Community Medicine, Information and Health Decision Sciences, Faculty of Medicine, University of Porto, Alameda Hernani Monteiro, 4200-319 Porto, Portugal"},{"name":"CINTESIS@RISE, MEDCIDS, Faculty of Medicine, University of Porto, Alameda Hernani Monteiro, 4200-319 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1939-2617","authenticated-orcid":false,"given":"Daniel","family":"Beir\u00e3o","sequence":"additional","affiliation":[{"name":"Department of Community Medicine, Information and Health Decision Sciences, Faculty of Medicine, University of Porto, Alameda Hernani Monteiro, 4200-319 Porto, Portugal"},{"name":"CINTESIS@RISE, MEDCIDS, Faculty of Medicine, University of Porto, Alameda Hernani Monteiro, 4200-319 Porto, Portugal"}]},{"given":"Paula","family":"Rocha","sequence":"additional","affiliation":[{"name":"Center for Research in Higher Education Policies (CIPES), Universities of Aveiro and Porto, Rua 1\u00ba Dezembro 399, 4450-227 Matosinhos, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2362-5527","authenticated-orcid":false,"given":"Paulo","family":"Santos","sequence":"additional","affiliation":[{"name":"Department of Community Medicine, Information and Health Decision Sciences, Faculty of Medicine, University of Porto, Alameda Hernani Monteiro, 4200-319 Porto, Portugal"},{"name":"CINTESIS@RISE, MEDCIDS, Faculty of Medicine, University of Porto, Alameda Hernani Monteiro, 4200-319 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,26]]},"reference":[{"key":"ref_1","unstructured":"Neinstein, L.S.
