Brief summary
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.
Detailed description
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.
Interventions
BEHAVIORALNon-personalised diet advice delivered via the eNutri app (control)
Non-personalised dietary advice to improve food choices based on standard population guidelines delivered by the eNutri app and irrespective of the dietary intakes from the food frequency questionnaire (control group).
BEHAVIORALPersonalised diet advice delivered via the eNutri app (intervention)
Personalised dietary advice to improve food choices based on adherence to an 11-item diet quality score, which is determined by the eNutri app in response to the dietary intakes from the food frequency questionnaire (intervention group).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| eNutri diet quality score (DQS) | Baseline & week 12 | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Body mass index (BMI) | Baseline & week 12 | Self reported measurements of weight and height will be used to determine BMI. |
