RESUMEN
BACKGROUND: The relationship between adolescent obesity and eating disorders is an issue that needs urgent attention. Screening for eating disorders is as important as dietary interventions to treat obesity. This study aimed to determine the relationship between hedonic hunger, food addiction, and night eating syndrome, which are considered potential risk factors for obesity, and body mass index (BMI) in adolescents. METHODS: The data were collected through an online questionnaire. The "Power of Food Scale (PFS)" was used to assess hedonic hunger; the "Yale Food Addiction Scale for Children 2.0 (dYFAS-C 2.0)" was used to assess food addiction; and the "Night Eating Questionnaire (NEQ)" was used to assess night eating syndrome (NES)". BMI was calculated using self-reported height and weight values of adolescents. The mediated structural model analysis was performed to evaluate the effect of hedonic hunger on BMI z score via food addiction and NES. RESULTS: The study was conducted with 614 voluntary adolescents aged between 11 and 18 years. The dYFAS-C 2.0 and NEQ scores were found to be higher in adolescents with overweight and obesity, and the BMI z-score of the adolescents had significant positive correlation with their PFS scores (p < .001). Hedonic hunger has no direct effect on BMI independent of food addiction and NES (ß = - 0.051, p = .468), but when the total indirect effect is evaluated with the bootstrap analysis, it was found that one-unit increase in hedonic hunger score increases BMI z-score by approximately 0.22 units (ß = 0.223, SE = 0.046, 95% CI 0.131-0.313). Hedonic hunger, food addiction, and NES together explained 5.2% of the total variance in BMI z score. CONCLUSION: This study showed that hedonic hunger significantly predicted BMI z-score in adolescents through food addiction and NES. This emphasizes the critical importance of evaluating adolescents in terms of hedonic hunger, food addiction, and NES in the prevention, diagnosis, and treatment of obesity.
The relationship between adolescent obesity and eating disorders is an issue that requires urgent attention. This study was conducted to determine the relationship between hedonic hunger (drive to eat for pleasure in the absence of true physical hunger), food addiction and night eating syndrome and obesity in adolescents. An online questionnaire, which assessed hedonic hunger, food addiction, and night eating syndrome, was administered to adolescents with parental consent. The study was conducted with 614 volunteer adolescents aged between 11 and 18 years. Adolescents with overweight and obesity were found to have a higher tendency to food addiction and night eating syndrome. In addition, as the hedonic hunger tendency of adolescents increased, body mass index also increased. This emphasizes the critical importance of assessing adolescents in terms of hedonic hunger, food addiction and night eating syndrome in the prevention, diagnosis, and treatment of obesity.
RESUMEN
This study aimed to adapt the Test of Orthorexia Nervosa- (TON-17) into Turkish and verify its validity and reliability. The study included 539 adults with a mean age of 30.2 ± 12.26 years. A reliability analysis was performed, along with a confirmatory factor analysis to test its construct validity. The time-invariance of the scale was examined by test-retest analysis, and its convergent validity was evaluated by a correlation analysis conducted to test the relationships between the scale and Eating Attitudes Test-26 and Obsessive Beliefs Questionnaire-9. Analyses were conducted using SPSS Version 28 and the AMOS-24 software. The Cronbach's α internal consistency coefficient of the total scale was found to be 0.82, suggesting a strong internal consistency. The Cronbach's α values of its factors were 0.68 for the "control of food quality", 0.64 for the "fixation on health and a healthy diet", and 0.73 for the "disorder symptoms". In addition, the test-retest reliability was found to be 0.87 for the total scale, suggesting excellent reliability. Most of the fit indices (CMIN/df, RMSEA, AGFI, NFI, and TLI) of the scale were acceptable, and the GFI indicated a good model fit. This study shows that the Turkish version of TON-17, which is a new tool with a three-factor structure to evaluate orthorexia, is a valid and reliable scale.

Background: Dietary patterns and their possible effects on health and the environment are becoming increasingly important. It is thought that nutritionally balanced diets can also be compatible with environmental targets and, therefore, the Mediterranean diet (MD), which is regarded as a sustainable diet model, comes to the fore. This study was carried out to evaluate adherence to the MD with sustainable nutrition knowledge and environmentally responsible food choices and to determine the factors affecting adherence. Methods: A questionnaire prepared by the researchers was sent to individuals online and 1732 adults living in Turkey participated in this cross-sectional study. Adherence to the MD was evaluated with the Mediterranean Diet Adherence Screener (MEDAS). In addition, questions were asked about nutritional knowledge and environmentally responsible food choices to evaluate the sustainable nutritional behaviors of individuals. Results: Half of the participants (51.1% of men / 53% of women) adhere to the MD at a moderate level. Even the individuals with the highest adherence to the MD had low compliance with the recommendations for fruit (43.4%) and fish (37.3%) consumption. A one-unit increase in age, sustainable nutrition knowledge score, and environmentally responsible food choices score increases the MD adherence score by 0.08, 0.125, and 0.148 points, respectively (p < 0.005). Individuals with high adherence to the MD avoid consuming genetically modified organism food more (p < 0.001), prefer to consume environmentally labeled foods (p < 0.001), and buy food more from local businesses (p < 0.001), while they prefer to buy imported food less (p = 0.034). Conclusion: The results of this study showed that some strategies should be developed to increase the adaptation of individuals to the MD and sustainable nutritional behaviors. Nutritionally adequate, sustainable, and eco-friendly nutritional behaviors should be encouraged to increase the possible health benefits of nutrition and minimize environmental effects. To promote sustainable nutrition, firstly it is important to determine the knowledge level of individuals concerning sustainable nutrition and, for this purpose, it is thought that an international valid sustainable nutrition knowledge assessment tool is needed.
RESUMEN
As in almost every country in the world, street foods are frequently used in Turkey. To determine the preferences for these foods, a questionnaire was given to 847 individuals constituted by randomly selected high school and university students. Of the participants, 43.4% were male and 56.6% were female; the majority of them were between 19 and 22 years of age. It was found that 40.1% of the young people ate street food 2-3 times per week, whereas 23.3% were found to eat it every day. Turkish bagels, döner, boiled corn in a cup and toast are most preferred street foods. A statistically significant negative correlations were found between consumption preference scores and education, gender, and age. Although consumers know that street foods can cause contamination with microorganisms, that sellers do not pay attention to hygiene, and that these foods are raw or not cooked well, they prefer because of their cheapness, deliciousness, variety and fast service. Street foods are widely consumed in Turkish young students and because of preventing food poisoning, they should be educated about food hygiene and safety. Also, educating vendors in personal hygiene and good manufacture practice can minimize contamination risk.

Resumo Alimentos de rua são frequentemente consumidos na Turquia como em quase todos os países do mundo. Foi aplicado um questionário para 847 indivíduos constituídos por estudantes de nível médio e superior que foram aleatoriamente selecionados. Dos participantes, 43,4% eram do sexo masculino e 56,6% do feminino; a maioria deles tinha entre 19 e 22 anos de idade. Foi constatado que 40,1% dos jovens comem alimentos de rua 2-3 vezes por semana, enquanto 23,3% todos os dias. Bagel turco döner, milho cozido em um copo e pão torrado são os alimentos de rua mais preferidos. A correlação negativa estatisticamente significativa foi encontrada entre as pontuações de preferências de consumo e educação, gênero e idade. Embora os consumidores saibam que os alimentos de rua podem causar contaminação com microrganismos, pois os vendedores não prestam atenção à higiene, e que estes alimentos são crus ou mal cozidos, eles preferem por causa de seus custos baratos, o seu gosto, a variedade e o serviço rápido. Alimentos de rua são amplamente consumidos por jovens e estudantes turcos e para prevenir a intoxicação alimentar, eles devem ser educados sobre higiene e segurança alimentar. Além disso, educar fornecedores sobre higiene pessoal e boas práticas de fabricação podem minimizar o risco de contaminação.

Investigating eating disorders and orthorexia nervosa, especially in the young population, is an important step in taking protective precautions and identifying disease. This study was carried out to determine the relationship of eating disorders and orthorexia nervosa to gender, BMI, and field of study in a population of university students in Turkey. In all, 900 university students aged 17-23 years participated in this study. EAT-40 and ORTO-15, which are validated instruments for the screening of participants with anormal eating behaviors and orthorexia nervosa, respectively, were used. There was not a significant difference in EAT-40 scores according to gender and BMI classification. However, EAT-40 scores were high among the students in social science. The number of orthorectic participants among women is higher than that among men, and ORTO-15 scores were not associated with BMI classification and field of study. A significant negative correlation was found between EAT-40 and ORTO-15 scores.

BACKGROUND: There is insufficient information about the appetite-related hormones orexin-A, nesfatin-1, agouti-related peptide (AgRP), and neuropeptide Y (NPY) in hyperthyroidism. The aim of the present study was to investigate the effects of hyperthyroidism on the basal metabolic rate (BMR) and energy intake, orexin-A, nesfatin-1, AgRP, NPY, and leptin levels in the circulation, and their relationship with each other and on appetite. METHODS: In this prospective study, patients were evaluated in hyperthyroid and euthyroid states in comparison with healthy subjects. Twenty-one patients with overt hyperthyroidism and 33 healthy controls were included in the study. RESULTS: Daily energy intake in the hyperthyroid state was found to be higher than that in the euthyroid state patient group (p=0.039). BMR was higher in hyperthyroid patients than the control group (p=0.018). Orexin-A was lower and nesfatin-1 was higher in hyperthyroid patients compared to the controls (p<0.001), whereas orexin-A increased and nesfatin-1 decreased after euthyroidism (p=0.003, p<0.001). No differences were found in the AgRP, NPY, and leptin levels between the hyperthyroid and euthyroid states and controls (p>0.05). Orexin-A correlated negatively with nesfatin-1 (p=0.042), BMR (p=0.013), free triiodothyronine (fT3; p<0.001), and free thyroxine (fT4; p<0.001) and positively with thyrotropin (TSH; p<0.001). Nesfatin-1 correlated negatively with orexin-A (p=0.042) and TSH (p<0.001) and positively with fT3 (p=0.005) and fT4 (p=0.001). In the regression analysis, "diagnosis of hyperthyroidism" was the main factor affecting orexin-A (p<0.001). CONCLUSIONS: Although it seems that no relationship exists among orexin-A, nesfatin-1, and increased appetite in hyperthyroidism, the orexin-A and nesfatin-1 levels are markedly affected by hyperthyroidism.

Orexin-A and ghrelin are two important polypeptides that stimulate food intake, however, there is a lack of sufficient information concerning their plasma levels in patients with chronic obstructive pulmonary disease (COPD). The aim of the present study was to investigate the association between plasma orexin-A and ghrelin levels with food consumption and body composition in patients with stable phase COPD. In total, 40 patients (age, 44-80 years; male, 31; female 9) who were in the stable phase of COPD were included in the study. Blood samples for plasma orexin-A and ghrelin analysis were collected after 8-12 h of fasting; certain anthropometric measurements were obtained and a 24-h dietary recall was recorded. The mean plasma orexin-A levels in the male and female patients were 1.3±0.37 and 1.4±0.13 ng/ml, respectively, while the mean plasma ghrelin levels were 25.9±7.31 and 27.3±8.54 ng/ml, respectively. No significant correlation was observed between the body mass index and plasma orexin-A and ghrelin levels or between the plasma ghrelin levels and dietary nutrient intake (P>0.05). The plasma orexin-A levels were demonstrated to be higher in patients with a higher dietary total fibre intake (r=0.303, P=0.022). A similar correlation was observed between plasma orexin-A levels and dietary intake of soluble (r=0.033, P=0.029) and insoluble (r=0.335, P=0.024) fibre, as well as between the daily consumption of calcium and the levels of plasma orexin-A (r=0.065, P=0.046). Therefore, the results of the present study indicated that a positive correlation existed between dietary nutrient intake and plasma orexin-A levels in patients with COPD.
RESUMEN
OBJECTIVE: Gastric cancer is an important public health problem in the world and Turkey. In addition to Helicobacter pylori (H. pylori), smoking, alcohol consumption and family history, certain dietary factors have been associated with its occurrence. The impact of dietary habits and life-style factors on the risk of gastric cancer in Turkey were evaluated in this study. DESIGN: A questionnaire was applied to 106 patients with gastric adenocarcinoma and 106 controls without cancer matched for age (range 28-85 years) and gender selected from a hospital based population. Adjusted odds ratios (ORs) and 95% confidence intervals (CI) were calculated with logistic regression analysis. RESULTS: The incidence of H. pylori was 81.3% in patients. Frequent consumption of salty dishes, very salty foods like pickles, soup mixes, sausages, foods at hot temperature (ORs=3.686, 7.784, 5.264, 3.148 and 3.273 respectively) and adding salt without tasting (OR=4.198) were associated with increased gastric risk. Also heavy smoking and high amount of alcohol consumption (p=0.000) were risk factors. Frequent consumption of green vegetables, onion, garlic and dried fruits (ORs=0.569, 0.092, 0.795 and 0.041) was non- significantly associated with decreased risk. CONCLUSION: Improved dietary habits, reducing salt consumption and eradication of H. pylori infection may provide protection against gastric cancer in Turkey.
