Contrary to expectations, body image was negatively associated with achievement in both groups, meaning that adolescents more satisfied with their bodies performed less well. The association was more than twice as strong among obese adolescents, the only between-group difference observed, and it did not persist after adjustment for multiple comparisons. Psychosomatic symptoms also showed a positive relationship with achievement, contrary to what the literature reports, reaching significance among obese adolescents alone, while perceived school safety reached significance only among their non-obese peers; in neither case did the groups differ. Curiosity, emotional control, and perseverance were positively related to achievement in both groups, and social connections, cooperation, and school risk were negatively related.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>These findings locate the difference associated with obesity in adolescents' body-related self-perception rather than in the relational or institutional resources available to them. Educational strategies that address weight-inclusive environments and bias training may therefore complement traditional health-focused interventions in supporting these students.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fpsyg.2026.1916078","type":"journal-article","created":{"date-parts":[[2026,9,23]],"date-time":"2026-09-23T06:20:33Z","timestamp":1790144433000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Bioecological correlates of learning outcomes: testing the moderating role of obesity in academic performance"],"prefix":"10.3389","volume":"17","author":[{"given":"Izzettin","family":"Aydogan","sequence":"first","affiliation":[{"name":"Faculty of Education, Van Y\u00fcz\u00fcnc\u00fc Y\u0131l University","place":["Van, T\u00fcrkiye"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,23]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"e079783","DOI":"10.1136\/bmjopen-2023-079783","article-title":"Utilisation of the health belief model to study the behavioural intentions relating to obesity management among university students: a cross-sectional study","volume":"14","author":"Albasheer","year":"2024","journal-title":"BMJ Open"},{"key":"B2","doi-asserted-by":"publisher","first-page":"e0334407","DOI":"10.1371\/journal.pone.0334407","article-title":"Saudi adolescents' perceptions of dietary contributions to obesity: a qualitative study","volume":"20","author":"Alqahtani","year":"2025","journal-title":"PLoS ONE"},{"key":"B3","doi-asserted-by":"publisher","first-page":"1623411","DOI":"10.3389\/fpsyt.2025.1623411","article-title":"Family-based weight stigma and psychological wellbeing of adolescents: a longitudinal analysis of recent vs","volume":"16","author":"Anastasiadou","year":"2025","journal-title":"cumulative exposure.
