Electronic-Nutrition-Optimizer for Personalized Prevention

Heike Bischoff-Ferrari88 enrolled

Overview

This study aims to develop and validate a tool for immediate nutrition assessment and to test its user feasibility in routine clinical practice for health promotion.

Small changes in diet have been shown to have an important impact on health and the risk of age-related chronic diseases, such as cardiovascular disease, diabetes, frailty and dementia. However, this knowledge has not yet been implemented into routine clinical practice, because practical tools that allow a comprehensive nutrition assessment in the clinical care setting are missing. In addition, doctors are generally not educated in giving nutritional advice to patients. In this pilot project, we aim to push forward and enable the potential of nutrition as a core primary prevention strategy for people at risk of developing chronic diseases. This will be achieved by using, as a stepping stone, the electronic 216-food-item food frequency questionnaire which was developed for the European DO-HEALTH study and was tested in over 2000 adults. The investigators want to extend this tool to not only capture the personal dietary intake, but also to produce an immediate report, comparing the personal diet to the Mediterranean and MIND diet patterns and providing a patient's intake of protein and other nutrients. The report will additionally indicate the patient's diet-related, personalized risks of cardio-vascular disease, diabetes, frailty and cognitive decline, and recommend dietary changes to reduce these risks.

Interventions

eNutrition OptimizerDEVICE

The eNutrition optimizer is based on the electronic food frequency questionnaire (FFQ) used in the multicentre randomized controlled trail DO-HEALTH \[56\] developed by the CAM. The FFQ is split up in sections of 33 food groups and contains 216 items. It asks the user on the relative frequency of consumption of the different foods showing a picture of the food in the portion size of interest. Within the eNutrition Optimizer, the FFQ will be extended to create an output of the user's adherence to the Mediterranean diet, the MIND diet and the adherence with the current dietary recommendations for micro- and macronutrients provided by the Swiss Society for Nutrition and the DACH-references, compare it to the DO-HEALTH population and give recommendations on how to improve the score.
