Brief Summary

This study examines differences in nutrition and eating behaviors among adolescents living in two regions of Türkiye with contrasting socioeconomic and cultural conditions. A total of 100 adolescents aged 14-18 years were recruited from high schools in Ağrı (Eastern Türkiye) and Kırklareli (Western Türkiye). Participants completed dietary recalls, the Healthy Nutrition Behavior Scale, and the Eating Attitudes Test (EAT-26). The study aims to understand how regional inequalities influence nutrient intake and eating behaviors. Findings may help guide future public health strategies to improve adolescent nutrition across different regions of Türkiye.
