Brief Summary:
This research aims to adapt and validate the web-based eNutri Food Frequency Questionnaire FFQ and Diet Quality Score DQS for the Turkish population addressing the current gap in dietary assessment tools for Turkey The study involves adapting the UK-based eNutri FFQ to reflect Turkish dietary habits including revising the food list capturing portion size photos and incorporating local food composition data The revised FFQ will be validated against three 24-hour dietary recalls and tested for reproducibility
Detailed Description:
Background Non-communicable diseases NCDs such as cardiovascular diseases are important global health concerns Accurate dietary assessment is pivotal in understanding the relationship between food intake and health outcomes Presently there is a notable absence of a comprehensive dietary assessment tool tailored for the Turkish population
Objective The primary objective of this research is to adapt and validate the web-based eNutri Food Frequency Questionnaire FFQ and Diet Quality Score DQS for the Turkish population addressing the current gap in dietary assessment methods
Design and Proposed Analysis The first part of the study will involve adapting the UK-based e-Nutri FFQ to reflect dietary habits of Turkish adults eNutri-Turkey such as revising the food list taking portion size photos and incorporating Turkish food composition data The revised FFQ delivered online will be validated against three 24-hour recalls by phone reference method and the FFQ will be administered twice to assess reproducibility The study will employ Cronbachs Alpha for internal consistency and the Bland-Altman method for validity Additionally inter-rater reliability and reproducibility will be assessed through Cohens Kappa and ICC analysis respectively The eNutri DQS will be adapted in accordance with Turkish dietary guidelines Following the adaptation its validity will be assessed using existing Turkish population nutrient data This analysis will involve retrospectively calculating the DQS and examining its associations with key risk markers of chronic diseases BMI blood pressure blood glucose and cholesterol levels Additionally two qualitative studies will be conducted before starting the validation study Dietitians and nutrition academics from Turkey n10 will provide insights on the suitability and effectiveness of eNutri-Turkey through one-to-one interviews Feedback received will be used to improve the FFQ and DQS
