About this study
Official title: Regional Nutritional Inequalities and Eating Behaviors Among Turkish Adolescents: A Cross-Regional Analysis
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.
Read the detailed description
Adolescence is a critical developmental stage where nutritional habits are formed and often persist into adulthood. Nutritional inequalities in Türkiye are shaped by socioeconomic and cultural disparities between regions. This cross-sectional observational study was conducted between April and June 2025 in two provinces representing distinct socioeconomic contexts: Ağrı in Eastern Türkiye and Kırklareli in Western Türkiye.
A total of 100 adolescents (50 from each province) aged 14-18 years participated voluntarily. Dietary intake was assessed using 24-hour dietary recalls, and nutrient composition was analyzed with the BeBiS v9.0 software. Healthy eating behaviors were measured with the Healthy Nutrition Behavior Scale (HNBS), and disordered eating attitudes were evaluated with the Eating Attitudes Test (EAT-26).
The primary objective was to compare nutrient intake, healthy eating behaviors, and eating attitudes between the two provinces. Secondary analyses examined whether dietary patterns predicted psychosocial outcomes. Statistical methods included linear mixed-effects models, multivariate analysis of covariance, and principal component regression, adjusting for demographic and socioeconomic covariates.
Ethical approval was obtained from the Ağrı İbrahim Çeçen University Scientific Research and Publication Ethics Committee (Decision No: 112, March 27, 2025). All participants and their guardians provided informed consent.
This study is expected to generate evidence on regional nutritional disparities among adolescents in Türkiye. Results may inform dual public health strategies: (i) improving access to nutrient-dense foods in disadvantaged regions and (ii) addressing over-nutrition and processed food consumption in more affluent regions.

| Study group | Role | What they receive |
|---|---|---|
| Kırklareli Cohort | Adolescents selected from secondary and high schools in Kırklareli, Türkiye. Observational data collection included 24-hour dietary recall, Healthy Nutrition Behavior Scale (HNBS), and Eating Attitudes Test (EAT-26). No intervention was applied | |

What is being measured
The primary outcome is the main question the study is designed to answer.
Eating Attitudes (EAT-26)
Scores on the Eating Attitudes Test-26 (EAT-26), a validated screening tool for disordered eating attitudes in adolescents
Measured: Cross-sectional, single assessment (April-June 2025).
Healthy Nutrition Behavior Score (HNBS)
Scores on the Healthy Nutrition Behavior Scale (HNBS), a validated 20-item instrument for adolescents. Each item is rated on a 5-point Likert scale (1=never to 5=always). Higher total scores indicate healthier nutrition behaviors.
Measured: Single cross-sectional assessment at baseline (April-June 2025).
Nutrient Intake (24-hour recall)
Energy and nutrient intake (e.g., protein, fat, carbohydrates, vitamins, minerals) based on a 24-hour dietary recall and analyzed using BeBiS v9.0 software.
Measured: Cross-sectional, single assessment (April-June 2025).

The record says: finished, as of the sponsor's last update on 26 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Eating Attitudes (EAT-26) (time frame: Cross-sectional, single assessment (April-June 2025).). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
