Results showed that students consumed an average of 1.98±1.42 servings of fruit and 2.05±1.61 servings of vegetables daily, with higher intake of meat (2.00±1.24) than fish (1.00±1.21). Gender differences were found (p<0.05): males consumed more meat while females ate more vegetables and practiced voluntary fasting more frequently. On average, students engaged in physical activity 3.15±2.62 days per week, with males being significantly more active. Screen time was considerable (1.52±0.88 hours TV; 2.73±1.34 video games). Correlations revealed positive associations between physical activity and healthy food consumption (r>0.39), while sedentary behaviors were related to unhealthy foods (r>0.43). These findings suggest the need for specific interventions that promote healthy habits within the school environment.2026http://zaguan.unizar.es/record/17010710.6018/sportk.695111http://zaguan.unizar.es/record/170107oai:zaguan.unizar.es:170107info:eu-repo/grantAgreement/ES/DGA-CUS/1638-2022info:eu-repo/grantAgreement/ES/DGA/S53-23RSport TK 14 (2026), 158 [17 pp.]by-nc-ndhttps://creativecommons.org/licenses/by-nc-nd/4.0/deed.esinfo:eu-repo/semantics/openAccess
