Summary

The aim is to determine whether the eNutri web application can effectively estimate the dietary intake of a UK older population. The eNutri FFQ65+ study will validate the eNutri online food frequency questionnaire (FFQ) using 100 adults aged 65+ years. The FFQ will be validated against an online 24-hour dietary recall system (Intake24) and its reproducibility will be evaluated by the completion of two FFQs within a 14-day interval. In addition, all participants will also be asked to provide dried blood spot (DBS) samples which will be analysed for key biomarkers of nutritional intake and health. Biomarker results will be compared to FFQ results to further validate the eNutri FFQ.

Detailed description

The primary objective of this study is to validate the eNutri FFQ65+ that assesses dietary intake for the previous 4 weeks against a widely-used, validated computer based 24-hour dietary recall system (Intake24), which is the dietary assessment tool currently used by the UK's National Diet and Nutrition Survey Rolling Programme. The second objective, the reproducibility of the FFQ 65+ dietary data, will also be tested by asking participants to complete the eNutri FFQ on two separate occasions with a 14-day interval between both. In addition, after completing the first FFQ, DBS will be collected from all participants to further validate the FFQ results against selected biomarkers, for example markers of nutrient intake, such as carotenoids, and markers of health, such as cholesterol.
