Methods: This cross-sectional online study was conducted on Portuguese university students. All students completed a questionnaire consisting of demographic characteristics, e-health Literacy Scale (eHEALS), and a questionnaire about knowledge, attitude, and health online information seeking. Results: A total of 534 students (76.8% women), with a mean age of 24.3 years old (SD = 7.8), participated in this cross-sectional study, 53.0% of students were from non-health sciences. The mean score of eHEALS literacy was 28.8 (SD = 5.6). Most students (71.1%) classified the Internet as a useful, or very useful, tool in helping them make health related decisions. The use of the Internet as a tool to research health information for a period of two or more hours (OR = 1.9; CI 95% = 1.2; 3.4), to search online for health information on professional websites (OR = 2.3; CI 95% = 1.4; 3.6), to search in official media (OR = 2.3; CI 95% = 1.4; 3.9), and to study in the field of health sciences (OR = 1.6; CI 95% = 1.1; 2.6) increased the likelihood of having sufficient e-health literacy. Conclusion: From a public health perspective, there is a need to develop programs that increase health literacy among university students.<\/jats:p>","DOI":"10.3390\/ijerph21030271","type":"journal-article","created":{"date-parts":[[2024,2,27]],"date-time":"2024-02-27T11:52:55Z","timestamp":1709034775000},"page":"271","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Evaluating E-Health Literacy, Knowledge, Attitude, and Health Online Information in Portuguese University Students: A Cross-Sectional Study"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1874-0432","authenticated-orcid":false,"given":"Sofia","family":"Almeida","sequence":"first","affiliation":[{"name":"Centre for Interdisciplinary Research in Health (CIIS), Faculty of Health Sciences and Nursing, Universidade Cat\u00f3lica Portuguesa, 4169-055 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9028-8009","authenticated-orcid":false,"given":"Elisabete","family":"Pinto","sequence":"additional","affiliation":[{"name":"Centro de Biotecnologia e Qu\u00edmica Fina, Escola Superior de Biotecnologia, Universidade Cat\u00f3lica Portuguesa, 4169-005 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5040-735X","authenticated-orcid":false,"given":"Marta","family":"Correia","sequence":"additional","affiliation":[{"name":"Centro de Biotecnologia e Qu\u00edmica Fina, Escola Superior de Biotecnologia, Universidade Cat\u00f3lica Portuguesa, 4169-005 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6288-0435","authenticated-orcid":false,"given":"N\u00e9lio","family":"Veiga","sequence":"additional","affiliation":[{"name":"Centre for Interdisciplinary Research in Health (CIIS), Faculty of Dental Medicine, Universidade Cat\u00f3lica Portuguesa, 3504-505 Viseu, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5329-0625","authenticated-orcid":false,"given":"Armando","family":"Almeida","sequence":"additional","affiliation":[{"name":"Centre for Interdisciplinary Research in Health (CIIS), Faculty of Health Sciences and Nursing, Universidade Cat\u00f3lica Portuguesa, 4169-055 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2024,2,27]]},"reference":[{"key":"ref_1","unstructured":"Selden, C.R., Zorn, M., Ratzan, S.C., and Parker, R.M.
