Validation of the Turkish version of the power of food scale in adult population.

PURPOSE: The Power of Food Scale (PFS) is a tool for measuring the hedonic impact of food environments rich in palatable foods. The purpose of this study was to validate the Turkish version of PFS (PFS-Tr) in a large adult population. METHODS: Data were obtained from 505 Turkish adults aged between 19 and 64 years. The PFS-Tr and Dutch Eating Behavior Questionnaire (DEBQ) were completed by all participants. RESULTS: PFS-Tr compared with the original English version of PFS, items 5 and 13, which showed the highest error covariance under the food available factor. To provide general criteria, items 5 and 13 were removed. After these two items were removed, the Cronbach's alpha coefficient was 0.922 for PFS-Tr and Cronbach's alpha values for "food available", "food present", and "food taste" were found to be 0.849, 0.797, and 0.82, respectively. Besides, the Cronbach's alpha coefficient was 0.93 for DEBQ. In addition, a linear association was found between BMI and mean score of PFS-Tr with a model fit (R2 = 0.02) and PFS-Tr was positively correlated with DEBQ (r 0.497 p < 0.001). CONCLUSION: This is the first study that validates and reports the Turkish version of PFS and the results of our study show that PFS-Tr is a valid and reliable tool for determining the tendency for the hedonic hunger in Turkish adult population. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.

The effects of bariatric surgery on gut microbiota in patients with obesity: a review of the literature.

Obesity is a disease with a rapidly increasing prevalence all over the world in recent years. Genetic and environmental factors are involved in the etiology of obesity, and the effect of microbiota on obesity is becoming increasingly clear. Obesity treatment has various treatment modalities such as behavior modification, medical nutrition therapy, physical activity enhancement, and surgical intervention. When other treatment methods are not successful, bariatric surgery is usually resorted to as the treatment method. Some changes such as food choices, the level of hormones and enzymes due to anatomical changes, pH of the stomach, and microbiota are observed after bariatric surgery. Alteration in the microbiota composition after bariatric surgery has also been reported to be important in achieving body weight loss and preserving body weight loss.
