This form of addiction can lead individuals to a sedentary lifestyle while also increasing the risk of them turning to unhealthy and ready-made foods. This study aimed to determine the prevalence of digital addiction among Turkish adolescents. We also aimed to determine the relationships between digital addiction, adherence to the Mediterranean diet, and physical activity, and to determine the extent to which these variables mutually predict each other.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>The data of this cross-sectional study were collected from 400 high school students through a survey. The survey included general information, dietary habits, the Digital Addiction Scale (DAS), the Mediterranean Diet Quality Index (KIDMED), the Leisure Time Exercise Questionnaire (LTEQ), and the Physical Activity Enjoyment Scale (PACES). IBM SPSS 25.0 software was used for data analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the students, 23.8% had a digital addiction. Eating during social media use (Beta\u202f=\u202f0.158) and night eating habits (Beta\u202f=\u202f0.337) positively affected the DAS scores (<jats:italic>p<\/jats:italic>\u202f&amp;lt;\u202f0.05). The KIDMED score (Beta\u202f=\u202f\u22120.233) and being physically active (Beta\u202f=\u202f\u22120.136) negatively affected the DAS scores (<jats:italic>p<\/jats:italic>\u202f&amp;lt;\u202f0.05). Compliance with the Mediterranean diet was low in 26%, moderate in 46%, and high in 28% of the students. The number of main meals (Beta\u202f=\u202f0.254) and father\u2019s education level (Beta\u202f=\u202f0.200) positively affected the KIDMED scores (<jats:italic>p<\/jats:italic>\u202f&amp;lt;\u202f0.05). Of the students, 51.5% were active, 32% were moderately active, and 16.5% were sedentary. The PACES scores positively affected the LTEQ scores (Beta\u202f=\u202f0.189, <jats:italic>p<\/jats:italic>\u202f&amp;lt;\u202f0.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Approximately a quarter of students had digital addiction symptoms. Digital addiction levels tended to decrease as Mediterranean diet adherence and physical activity levels increased. A holistic healthy lifestyle curriculum can be designed to promote healthy eating habits and physical activity among young people, reduce screen time, and increase media literacy. This curriculum, designed for implementation in schools, can support students in engaging in mindful behaviors.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fpubh.2025.1654322","type":"journal-article","created":{"date-parts":[[2025,9,3]],"date-time":"2025-09-03T05:37:31Z","timestamp":1756877851000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":8,"title":["Determinants and relationships of digital addiction, diet quality, and physical activity in adolescents"],"prefix":"10.3389","volume":"13","author":[{"given":"Gizem","family":"Helvac\u0131","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fatma","family":"Tayhan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,9,3]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"2277","DOI":"10.1001\/jama.2019.4690","article-title":"The challenges of defining and studying \u201cdigital addiction\u201d in children","volume":"321","author":"Christakis","year":"2019","journal-title":"JAMA"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"101832","DOI":"10.1016\/j.techsoc.2021.101832","article-title":"Combatting digital addiction: current approaches and future directions","volume":"68","author":"Cemiloglu","year":"2022","journal-title":"Technol Soc"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"519","DOI":"10.1007\/s10672-024-09493-6","article-title":"Digital addiction in organizations: challenges and policy implications","volume":"36","author":"Lam","year":"2024","journal-title":"Empl Responsib Rights J"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"201","DOI":"10.1542\/peds.2011-1066","article-title":"Children, adolescents, obesity, and the media","volume":"128","author":"Strasburger","year":"2011","journal-title":"Pediatrics"},{"key":"ref5","doi-asserted-by":"publisher","first-page":"101541","DOI":"10.1016\/j.clae.2021.101541","article-title":"Extended screen time and dry eye in youth","volume":"45","author":"Muntz","year":"2022","journal-title":"Contact Lens Anterior Eye"},{"key":"ref6","first-page":"149","article-title":"Youth's look for a healthy lifestyle","volume":"2","author":"Manasova","year":"2021","journal-title":"Central Asian J Med Nat Sci"},{"key":"ref7","doi-asserted-by":"publisher","first-page":"217","DOI":"10.1016\/j.jpedp.2018.09.001","article-title":"Adolescents\u2019 healthy lifestyle","volume":"96","author":"Marques","year":"2020","journal-title":"J Pediatria"},{"key":"ref8","doi-asserted-by":"publisher","first-page":"57","DOI":"10.1016\/S0376-8716(00)00165-4","article-title":"A twin study on sensation seeking, risk taking behavior and marijuana use","volume":"62","author":"Miles","year":"2001","journal-title":"Drug Alcohol Depend"},{"key":"ref9","doi-asserted-by":"publisher","first-page":"549","DOI":"10.1111\/joim.13333","article-title":"The Mediterranean diet and health: a comprehensive overview","volume":"290","author":"Guasch-Ferr\u00e9","year":"2021","journal-title":"J Intern Med"},{"key":"ref10","doi-asserted-by":"publisher","first-page":"283","DOI":"10.1016\/j.numecd.2017.01.002","article-title":"Adherence to the Mediterranean diet in children and adolescents: a systematic review","volume":"27","author":"Idelson","year":"2017","journal-title":"Nutr Metab Cardiovasc Dis"},{"key":"ref11","doi-asserted-by":"publisher","first-page":"240","DOI":"10.1007\/s13668-024-00526-y","article-title":"Effect of social media on diet, lifestyle, and performance of athletes: a review of current evidence","volume":"13","author":"Nath","year":"2024","journal-title":"Curr Nutr Rep"},{"key":"ref12","doi-asserted-by":"publisher","first-page":"53","DOI":"10.1016\/j.bandc.2015.08.006","article-title":"Eating with our eyes: from visual hunger to digital satiation","volume":"110","author":"Spence","year":"2016","journal-title":"Brain Cogn"},{"key":"ref13","doi-asserted-by":"publisher","first-page":"1212","DOI":"10.1038\/oby.2011.385","article-title":"Ghrelin levels increase after pictures showing food","volume":"20","author":"Sch\u00fcssler","year":"2012","journal-title":"Obesity"},{"key":"ref14","doi-asserted-by":"publisher","first-page":"377","DOI":"10.3390\/foods10020377","article-title":"Digital media use in association with sensory taste preferences in European children and adolescents\u2014results from the I.
