简要总结
The aim of this study is to test the efficacy, feasibility, and acceptability of a novel, behaviour-focused personalised nutrition intervention compared to a control personalised nutrition intervention for improving adherence to sustainable and healthy dietary recommendations in university students.
详细描述
Participants will be recruited from the University College Dublin (UCD) PLAN'EAT Living Lab (LL) Citizen Panel which will form a separate registration. The UCD PLAN'EAT LL is a series of studies designed to develop, implement, and evaluate strategies to support University students' transition towards a sustainable healthy diet. The UCD PLAN'EAT LL study will recruit up to n=500 healthy students (aged 18-30 years) attending UCD, Belfield Campus, to join the UCD PLAN'EAT LL Citizen Panel. Upon successful screening and completion of informed consent, participants will be invited to join the UCD PLAN'EAT LL Citizen Panel and complete initial baseline data collection measures (which will be detailed in a separate registration). Following completion of this baseline data collection, participants within the UCD PLAN'EAT LL Citizen Panel will be subsequently invited to participate in this study detailed below.
Participants within the UCD PLAN'EAT LL Citizen Panel will be invited to participate in a 4-week study. This study will aim to recruit n=40 participants within the UCD PLAN'EAT LL Citizen Panel. After successful screening and informed consent, participants will be randomised into two separate groups (n=20 control group; n=20 intervention group) receiving different types of personalised recommendations and strategies using decision tree algorithms to support them to consume a healthier and more sustainable diet. The control group will receive a personalised dietary plan and standardised behavioural support (based on previous personalised nutrition trials and usual care in dietetic practice) to meet their personalised dietary recommendations. The intervention group will receive the same as the control group, with the addition of receiving personalised behavioural support and strategies to help them meet their personalised dietary recommendations.
Baseline: Participants will be asked to complete a questionnaire including questions on demographics, health, dietary behaviours, and lifestyle and a dietary assessment. The dietary assessment will include 3 online 24-hour dietary recalls (2 non-consecutive weekdays and 1 weekend day) (via the web-based dietary recall tool, Foodbook24).
Following completion of baseline measures, participants will be invited to attend a study visit in UCD. Participants will undergo a diet counselling session, where they will receive a personalised feedback report and advice from a nutritionist on how to achieve their goal of eating a more sustainable and healthy diet.
Midpoint: Participants will be contacted by a member of the research team via email or phone message to check their progression and to address any queries.

结局指标
主要结局
Legume intake (grams per day)
时间窗: 4 weeks
Participants will record their diet at baseline (habitual diet) and endpoint (intervention diet) using an online 24-hour recall method. Legume intake will be calculated using dietary intake records (baseline: 3x 24-hour recalls; endpoint: 3x 24-hour recalls). The primary outcome measure is the change in legume intake (g/ day) as a result of the intervention diet.
次要结局
- Plant-based food intake (grams per day)(4 weeks)
- Fruit intake (grams per day)(4 weeks)
- Vegetable intake (grams per day)(4 weeks)
- Meat intake (grams per day)(4 weeks)
- High fat, sugar, salt (HFSS) food intake (grams per day)(4 weeks)
