The present study had the main goal of studying demographic, individual, social, and contextual variables related to health literacy in adolescents. Methods: The data used in this study are part of the Health Behavior in School-aged Children (HBSC) 2022 survey. The study included 7649 adolescents, 53.9% (n = 3961) female, with an average age of 15.05 years (SD = 2.36), in the 6th, 8th, 10th, and 12th grades, proportionally distributed across the five regions of the Portuguese mainland. Results: Health literacy was explained by factors related to physical, psychological, social, and environmental health. The factors with the higher explanatory value were the psychological variables, followed by social and lifestyle-related variables. Sociodemographic and environmental factors had a more modest explanatory value. These results point to the complexity of adolescents\u2019 health literacy. Conclusions: These results are of the utmost importance for educators, professionals, and policymakers who can use this information to create friendly environments that promote health literacy and health-promoting activities according to a multidisciplinary, continuous, and consistent plan.<\/jats:p>","DOI":"10.3390\/children12040410","type":"journal-article","created":{"date-parts":[[2025,3,24]],"date-time":"2025-03-24T13:48:20Z","timestamp":1742824100000},"page":"410","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A Biopsychosocial and Environmental Perspective of Youth Health Literacy in Portugal"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9616-0441","authenticated-orcid":false,"given":"Tania","family":"Gaspar","sequence":"first","affiliation":[{"name":"Digital Human-Environment Interaction Labs (HEI-LAB), Lus\u00f3fona University, Campo Grande, 1749-024 Lisbon, Portugal"},{"name":"Institute of Environmental Health (ISAMB), 1649-026 Lisbon, Portugal"},{"name":"Aventura Social, 1649-026 Lisbon, Portugal"},{"name":"Faculty of Medicine, University of Lisbon (FMUL), Campo Grande, 1649-028 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9183-9121","authenticated-orcid":false,"given":"Miguel","family":"Arriaga","sequence":"additional","affiliation":[{"name":"Dire\u00e7\u00e3o Geral da Sa\u00fade, 1000-123 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1784-5240","authenticated-orcid":false,"given":"Marina","family":"Carvalho","sequence":"additional","affiliation":[{"name":"Institute of Environmental Health (ISAMB), 1649-026 Lisbon, Portugal"},{"name":"Aventura Social, 1649-026 Lisbon, Portugal"},{"name":"Faculty of Medicine, University of Lisbon (FMUL), Campo Grande, 1649-028 Lisbon, Portugal"},{"name":"Manuel Teixeira Gomes Higher Institute, University Hospital Centre of Algarve, 8000-386 Portim\u00e3o, Portugal"},{"name":"Instituto Superior Manuel Teixeira Gomes, 8500-590 Portim\u00e3o, Portugal"}]},{"given":"F\u00e1bio","family":"Botelho-Guedes","sequence":"additional","affiliation":[{"name":"Institute of Environmental Health (ISAMB), 1649-026 Lisbon, Portugal"},{"name":"Aventura Social, 1649-026 Lisbon, Portugal"},{"name":"Faculty of Medicine, University of Lisbon (FMUL), Campo Grande, 1649-028 Lisbon, Portugal"}]},{"given":"Ana","family":"Cerqueira","sequence":"additional","affiliation":[{"name":"Institute of Environmental Health (ISAMB), 1649-026 Lisbon, Portugal"},{"name":"Aventura Social, 1649-026 Lisbon, Portugal"},{"name":"Faculty of Medicine, University of Lisbon (FMUL), Campo Grande, 1649-028 Lisbon, Portugal"}]},{"given":"Margarida","family":"Gaspar-Matos","sequence":"additional","affiliation":[{"name":"Institute of Environmental Health (ISAMB), 1649-026 Lisbon, Portugal"},{"name":"Aventura Social, 1649-026 Lisbon, Portugal"},{"name":"Faculty of Medicine, University of Lisbon (FMUL), Campo Grande, 1649-028 Lisbon, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"878","DOI":"10.1111\/j.1525-1497.2006.00540.x","article-title":"The meaning and the measure of health literacy","volume":"21","author":"Baker","year":"2006","journal-title":"J.
