What this Trial Is About
The aim of the SODIAT-2 study is to evaluate the effectiveness of dietary intake assessment tools in a real-world setting. These tools include wearable cameras, spot urine samples, capillary blood samples, and a web-based food frequency questionnaire (FFQ). The main questions it aims to answer are: Is the accuracy of dietary assessment improved in free-living environments when a combination of subjective and objective assessments tools are used? Secondary research questions are: Can wearable cameras accurately monitor the daily dietary intake of free-living individuals? Does a combination of capillary blood samples and spot urine samples provide a robust assessment of the nutrient status and habitual dietary exposure in a free-living setting? Can data-driven integration of multiple emerging technologies create a dietary assessment tool that is low burden, accurate and scalable in free-living populations? Can a condensed FFQ estimate diet quality as effectively as a detailed FFQ? Participants will: Use the dietary assessment tools (wearable camera, spot urine, capillary blood, and eNutri FFQ web-app) as instructed over a 5-week period from their home and/or working space. Take part in two monitoring weeks (week 1 and week 5) where they will record their usual dietary intake over 3 days. Consume an identical 3-day study meal plan during the test (calibration) diet week 3, whilst repeating the monitoring week measurements. This study aims to recruit 133 adults living in Great Britain (GB) to better understand how these tools perform outside of a clinical environment.
