- ItemThe role of chronotype, sleep quality, and physical activity in food cravings: a crosssectional study(BMC, 2025-07) Tuna, Tuğba; Karaca Çelik, Kezban Esen; Çelik Kayapınar, Fatma; 336342Introduction Food cravings contribute to unhealthy eating behaviors, increased energy intake, and metabolic disturbances. However, the interplay between chronotype, sleep quality, and physical activity in shaping food cravings remains unclear. This study explores these associations in adults attending fitness centers. Methods A cross-sectional study was conducted with 201 participants (80 females, 121 males) aged 19–64 years in İzmir, Türkiye. Validated tools, including the Food Craving Questionnaire-Trait (FCQ-T), Morningness–Eveningness Questionnaire (MEQ), and Pittsburgh Sleep Quality Index (PSQI), were used to assess food cravings, chronotype, and sleep quality, respectively. Results Regular physical activity was significantly associated with lower FCQ-T scores (p < 0.05). Poor sleep quality was linked to higher food craving levels (p < 0.05). Evening chronotypes showed higher food craving scores than morning types, though this was not statistically significant (p > 0.05). However, evening chronotypes exhibited significantly poorer sleep quality (higher PSQI scores) compared to morning types (p < 0.05). Conclusion This cross-sectional study suggests that regular physical activity and good sleep quality may be associated with lower food craving levels. Although chronotype differences were observed, further research is needed to clarify the underlying mechanisms. Given the limitations of the study design and potential selection bias, causal interpretations should be approached with caution. Nevertheless, interventions focusing on improving sleep and promoting physical activity may help reduce unhealthy eating tendencies in similar populations.
- ItemEvaluation of Nutritional Recommendations Provided by the ChatGPT Language Model to Bariatric Surgery Patients(Sciendo, 2025-03) Kumru Yildirim, Merve; Bayam, Hikmet; Yildiz, Nida; Gök Kahraman, Fatma; Acar, Nazli; 256218ChatGPT is recognized as a promising tool in healthcare by providing continuous support, quick accessibility, and personalized guidance for weight management [1]. In the field of bariatrics, the potential of ChatGPT in post-surgery weight management and nutrition is particularly noteworthy. In a study, the accuracy of the model’s general responses to bariatric questions was confirmed; however, the reliability of its responses to nutrition-specific issues has not yet been examined [2]. In this study, the aim is to evaluate the nutritional recommendations provided by the ChatGPT language model for patients following bariatric surgery through expert dietitians. This study was designed as a cross-sectional study. The responses provided by the free version of the ChatGPT 3.5 were evaluated by three experts in bariatric surgery. Initially, frequently asked postoperative nutrition questions were identified based on input from three experts who consult bariatric patients. This process led to the creation of 27 questions, which were then posed to ChatGPT in Turkish, with responses recorded immediately. For evaluation, responses were categorized as: '1: consistent with the guidelines', '2: consistent but incomplete', '3: consistent but contradictory', and '4: inconsistent'. The responses were assessed by two experts, with a third expert reviewing any disagreements.

- ItemThe role of nutrition and nutritional supplements in the prevention and treatment of malnutrition in chronic obstructive pulmonary disease: current approaches in nutrition therapy(Springer, 2025-01) Tuna, Tuğba; Samur, Gülhan; 336342Purpose of Review Malnutrition is a significant comorbidity in Chronic Obstructive Pulmonary Disease (COPD), contributing to disease progression and reduced quality of life. This narrative review examines the role of nutritional therapy in the prevention and management of malnutrition in COPD, emphasizing evidence-based approaches and their clinical implications. Recent Findings COPD patients face increased metabolic demands, systemic inflammation, and reduced dietary intake, resulting in muscle wasting, sarcopenia, and cachexia. Recent evidence highlights the efficacy of targeted nutritional strategies, including essential amino acid supplementation, omega-3 fatty acids, vitamin D, and antioxidants, in improving respiratory function, muscle strength, and patient well-being. Comprehensive nutritional assessments and personalized interventions are increasingly recognized as critical components of COPD care. However, long-term efficacy data remain limited. Summary Nutritional therapy plays a pivotal role in managing malnutrition and improving clinical outcomes in COPD. This review synthesizes the latest evidence, identifies gaps in current research, and proposes strategies for integrating personalized nutrition into COPD care. Future studies are needed to establish the long-term benefits of these interventions and to develop tailored nutritional guidelines for COPD patients.
- ItemThe predictive role of eating disorders and physical activity in findrisc diabetes risk: the sample of nutrition and dietetics students(Pontificia Universidade Catolica Campinas, 2024-06) Hamurcu, Pınar; Batar, Nazlı; 256218Objective The aim of this study was to investigate the effect of eating disorder risk and physical activity level on diabetes risk in students enrolled in the Department of Nutrition and Dietetics. Methods This cross-sectional descriptive study was conducted with 313 students enrolled in the Department of Nutrition and Dietetics at a private foundation university during the academic year of 2021-2022. Data was collected through face-to-face interviews using the Information Form, International Physical Activity Questionnaire, SCOFF Eating Disorders Scale, and Finnish Type-2 Diabetes Risk Questionnaire. The data was analyzed using IBM®SPSS® v.26 statistical software. Results Among the Nutrition and Dietetics students, 91.1% were female, mean age was 21.42±3.62 years, and mean body mass ındex was 21.72±3.25 kg/m2. According to International Physical Activity Questionnaire assessment, 8.9% of the students were categorized as inactive. The SCOFF Eating Disorders Scale assessment revealed that 25.6% of the students were at risk of developing an eating disorder. The Finnish Type-2 Diabetes Risk Questionnaire assessment indicated that 90.7% of the students had a low to slight risk of diabetes. The results of the correlation analysis showed that as International Physical Activity Questionnaire scores increased, Finnish Type-2 Diabetes Risk Questionnaire scores decreased by 16.8% (p=0.003), and as SCOFF Eating Disorders Scale scores increased, Finnish Type-2 Diabetes Risk Questionnaire scores also increased by 28% (p<0.001). The results of the multiple regression analysis showed that International Physical Activity Questionnaire significantly predicted Finnish Type-2 Diabetes Risk Questionnaire score, accounting for 3.8% of the variance, while SCOFF Eating Disorders Scale predicted Finnish Type-2 Diabetes Risk Questionnaire score, accounting for 8% of the variance (p<0.001). Conclusion The findings of this study suggest that physical activity level and susceptibility to eating disorders have a significant effect on the development of diabetes mellitus.
