Supporting University Students' Transition Towards Sustainable and Healthy Dietary Behaviours: A Living Lab Approach.

The University College Dublin (UCD) Living Lab (LL) is a series of small studies designed to develop, implement, and evaluate strategies and interventions to support university students' transition towards a sustainable and healthy diet. The LL will use a participant-centred process involving established LL methodology, with stakeholders and students actively feeding into the study design. The baseline and endpoint data collection measures of the UCD PLAN'EAT LL are described in detail below, followed by an outline of a series of planned studies. The final design and outcome(s) of each will evolve as the LL progresses.

Two groups will be recruited to the UCD PLAN'EAT LL: a) UCD student participants, and b) stakeholder participants, on or connected to UCD Belfield Campus. Student and Stakeholder involvement in the LL is detailed separately below.

1. Student participants

The 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 then complete an initial baseline data collection, as described below. Following completion of baseline data collection measures, participants within the UCD PLAN'EAT LL Citizen Panel will subsequently be invited to participate in a series of studies (Study 1 and Study 2 detailed below), which will each form a separate registration. Students will also be invited to attend sustainable and healthy diet-related events/ activities. Following baseline data collection, subsequent participation in the LL series of studies (Study 1 and Study 2) and events/ activities is optional for all participants recruited to the UCD PLAN'EAT LL Citizen Panel.
