    (Bayrakol Medical Publishing, 2024-10) Uray, Ecem Özge; Batar, Nazlı; Tuna Tuğba; 256218; 336342
    Aim: This study aimed to determine the effect of diet quality on nutritional status and type 2 diabetes risk in adult females. Material and Method: This study was conducted between January and March 2022 with the participation of 120 adult females who applied to Özel Maltepe Ersoy Hospital, Nutrition, and Diet Polyclinic for body weight control. The researchers recorded participant information form, IPAQ-SF, 24-hour retrospective food consumption record form, and FINDRISK data through face-to-face interviews. NAR and MAR scores were used to determine the diet quality of individuals. Results: It was determined that as body weight, BMI, waist circumference, waist-height ratio, neck circumference, body fat percentage, and fat mass values increased, the diabetes risk scores of individuals increased (p<0.05). It was determined that decreasing lean body mass and percentage increased the risk of diabetes (p<0.05). Biochemical parameters FBG, Insulin, HOMA-IR, TC, LDL-C, and TG values were found to be higher in individuals with high and very high diabetes risk compared to other individuals (p<0.05). It was determined that the risk of diabetes decreased as the physical activity levels of individuals increased (p<0.05). Diabetes risk score, and it was determined that there was no correlation between the biochemical parameters (p>0.05). Discussion: It has been determined that individuals’ anthropometric values, body composition, and physical activity level are important factors in the risk of diabetes. Appropriate health policies should be developed considering this situation.

    The 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; 336342
    Introduction 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.

    The 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; 336342
    Purpose 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.
