Study to Evaluate the 'eNutri' Online Personalised Nutrition App in the United Kingdom (UK)

University of Reading216 enrolled

Overview

The proof-of-principle EatWellEUR pilot study will investigate whether online personalised dietary advice encourages greater dietary behaviour change after 12 weeks compared with general population-based diet advice. Dietary change will be quantified from an 11-item diet quality score (DQS) suitable for Northern European populations that is calculated from the results of the eNutri food frequency questionnaire (FFQ) at baseline and week 12.

The proof-of-principle EatWellEUR pilot study will investigate whether online personalised dietary advice encourages greater dietary behaviour change after 12 weeks compared with general population-based diet advice. Both groups will receive two prompts to remind them of their diet advice at weeks 4 and 8. Dietary change will be quantified from an 11-item diet quality score (DQS) suitable for Northern European populations that is calculated from the results of the eNutri food frequency questionnaire (FFQ) at baseline and week 12. 98 participants will be recruited per study arm and will be randomly allocated to an intervention arm using a minimisation technique integrated with the eNutri app.

Outcomes

Primary Outcomes

eNutri diet quality score (DQS)

Dietary intake at baseline and week 12 will be assessed via the eNutri food frequency questionnaire (FFQ) from which an 11-item eNutri DQS will be calculated. The eNutri DQS was developed for Northern Europe and quantifies diet quality (i.e. the healthiness of a diet). It is composed of 11 food and nutrient components (contributing 10 points each) that are summed to give an overall score (between 0-110 points), where higher scores reflect the healthiest diets based on adherence to dietary recommendations.

Time frame: Baseline & week 12

Secondary Outcomes

Body mass index (BMI)

Self reported measurements of weight and height will be used to determine BMI.

Time frame: Baseline & week 12
