    Objective: Valid and reliable scales are required to determine and evaluate nutritional knowledge. This research aims to develop the nutrition knowledge scale for adults and to examine the factor structure, validity, and reliability. Methods: Initially, the Nutrition Knowledge Scale (NKS) was constituted, paying attention to content and construct validity. The content validity index (CVI) was found as 0.884. Five hundred eighty-five (371 females, 214 males) volunteers consisting of healthy adults completed the general information form and NKS. For test-retest reliability, 164 (28.03%) participants completed the NKS again within four weeks following the first conduct. Results: As a result of Explanatory Factor Analysis (EFA), NKS items were collected under one factor. According to the results of the Confirmatory Factor Analysis (CFA), all fit indices were found at an acceptable level. Cronbach's alpha value calculated for reliability analysis of NKS is 0.851. The intraclass correlation coefficient (ICC) calculated for test-retest reliability is 0.863. Conclusion: This research indicates that NCS is an acceptable, valid, and reliable scale that covers all aspects of nutritional knowledge and can be used in future research for determining and evaluating the nutritional knowledge level of adults.

    The effect of diets with different inflammatory scores on inflammation and sleep in obese subjects: a randomized controlled trial
    (Assoc Medica Brasileira, 2024) Toguc, Hakan; Yilmaz, Hande Ongun; Yaprak, Bulent
    OBJECTIVE: The aim of this study was to investigate the effect of different dietary inflammatory index diets on inflammatory markers, anthropometric measurements, and sleep quality in obese subjects. METHODS: This study was conducted in a public hospital in Turkey between November 2021 and May 2022. Participants with pro-inflammatory dietary habits were included in the study. Randomly divided into two groups of 33 participants, they were subjected to an anti-inflammatory control diet for 8 weeks. The study evaluated the anthropometric parameters, inflammatory biomarkers, and sleep quality indices of the diet RESULTS: Significant reductions in body mass index were observed in both groups, more marked in the anti-inflammatory diet cohort. C protein levels, indicative of inflammation, also decreased substantially in both groups, with a more marked reduction in the anti-inflammatory cohort. Despite the improvement in sleep quality in both groups, the variation was not statistically significant. CONCLUSION: This study demonstrates the importance of anti-inflammatory diets in nutritional strategies for obesity by reducing body mass and inflammation.
