简要总结
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.
详细描述
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.

研究组 & 干预措施
Non-personalised general diet advice
Control group to receive non-personalised dietary advice based on general public health dietary recommendations for Northern Europe. Advice will be delivered to the participant via the eNutri web application.
干预措施: Non-personalised diet advice delivered via the eNutri app (control) (Behavioral)
Personalised diet advice
Intervention group to receive personalised dietary advice generated by the eNutri app from their actual dietary intakes and tailored according to their body mass index and food preferences. Advice will be delivered to the participant via the eNutri app web application and will be generated based on their adherence to an 11-item diet quality score suitable for Northern European populations.

结局指标
主要结局
eNutri diet quality score (DQS)
时间窗: 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.
次要结局
