The DACCORD study is a participatory research project which aims to provide insights on how to involve higher education students and diverse partners in the co-creation of campus nutrition interventions through a deliberative mini-public.

The DACCORD study takes place at the University Sorbonne Paris Nord (USPN), located in the Seine Saint Denis department, in the Northern area of the Paris region (France). The intervention consists in a deliberative mini-public, a student citizen's assembly on diet and physical activity. The mandate of this student citizen's assembly is to co-create a list of concrete proposals that would improve the access of USPN students to sustainable diets and physical activity. The mini-public includes 30 students enrolled at USPN at the time of the study and a team of academic and non-academic partners involved in student life, nutrition, physical activity, or public policies.

The specific aims of the DACCORD study are 1) to design and implement a student citizens' assembly using participatory approaches, 2) to describe its process and evaluate its transferability, 3) to evaluate changes in nutritional habits, knowledge and citizen practices among students participating in the student citizen's assembly, using quantitative and qualitative methods.

Transferability will be evaluated continuously throughout the study, up to one year after completion of the student citizens' assembly. Nutritional habits, knowledge and citizen practices will be evaluated before and 1 months after the student citizens' assembly.

Inclusion Criteria:

• being an adult (18 years of age or older)
• being enrolled at USPN at the time of the study
• being enrolled in initial training with in-person classes

Exclusion Criteria:

• being enrolled in continuing education or work-study programs
