Objective: This study aims to evaluate the post-earthquake trauma levels and nutritional status of children aged 9–14 who experienced the Kahramanmaraş earthquake, and to examine the possible effects of trauma on their eating habits.

Materials and Methods: A total of 309 students aged 9 -14 years, who experienced the February 6 Kahramanmaraş earthquake and were attending a private school in the Onikişubat district of Kahramanmaraş, were included in the study between January and February 2025. Data were collected using a face-to-face questionnaire that included sociodemographic characteristics and basic nutritional habits. A 24-hour dietary recall method was used to assess daily energy and nutrient intake. The 'Child Post-Traumatic Stress Reaction Index (CPTS-RI)' was administered to determine trauma levels.

Results: The study included a total of 309 students (171 boys and 138 girls) aged 9–14 years. The mean age of participants was 11.35±1.28 years. Girls had significantly higher total trauma scores (31.91±16.46) compared to boys (26.84±14.56) (p=0.004). A statistically significant relationship was found between post-earthquake changes in appetite/eating habits and post-traumatic stress responses (p<0.001). Among girls, a weak but significant negative correlation was found between omega-3 fatty acid intake and trauma scores (r = –0.199, p=0.019). A weak but significant positive correlation was observed between BMI and trauma scores only in boys (r= 0.191, p=0.012).

Conclusion: The findings highlight the importance of addressing both the psychological and physical health of children in a holistic manner in the aftermath of disasters.
