About this study

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.

Treatment and study plan

Student citizens' assembly

Behavioral

The intervention consists in participating in a deliberative mini-public, a student citizens' assembly whose mission is to to co-create a list of concrete proposals that would improve the access of USPN students to sustainable diets and physical activity

Primary outcomes

  1. Transferability indicators (Reach indicator of the RE-AIM framework)

    Time frame: Throughout implementation of the student citizens assembly (5 months)

    Proportion and representativeness of students participating in the mini-public

  2. Transferability indicators (Effectiveness indicator of the RE-AIM framework)

    Time frame: Throughout implementation of the student citizens assembly (5 months)

    Qualitative analyses of the student citizens assembly proposals, in comparison with the recognized determinants of diet, using the DONE framework

  3. Transferability indicators (Adoption indicator of the RE-AIM framework)

    Time frame: Throughout implementation of the student citizens assembly (5 months)

    Aggregated data on the characteristics of non-student members of the mini-public (in terms of gender, age, employer and job description)

  4. Transferability indicators (Implementation indicator of the RE-AIM framework)

    Time frame: Throughout implementation of the student citizens assembly (5 months)

    Mini-public expertise, monetary cost of implementing the citizens' assembly, comparisont of actual vs. planned implementation

  5. Transferability indicators (Maintenance indicator of the RE-AIM framework)

    Time frame: One year after completion of the student citizens assembly

    Qualitative evaluation of the actual implementation of the citizens assembly proposals and willingness of USPN representatives to replicate the student citizens' assembly in another location or on another topic (evaluated through individual interviews with USPN representatives)

Secondary outcomes

  1. Changes in dietary habits

    Time frame: Before and one month after the student citizens' assembly

    Usual intake of the main food groups, assessed with a short food frequency questionnaire, and comparisons with current dietary recommendations

  2. Changes in sustainable dietary practices

    Time frame: Before and one month after the student citizens' assembly

    Sustainable dietary practices (usual intake of plant-based and animal products, consumption of ultra-processed foods, usual intake of organic food, food supply locations, use of a composter, food waste and recycling, meal preparation habits), assessed with the SHED index. A higher score indicates greater sustainable practices.

  3. Changes in knowledge of diet's environmental impact

    Time frame: Before and one month after the student citizens' assembly

    Knowledge of diet's environmental impact, assessed with a validated questionnaire. A higher score indicates greater knowledge.

  4. Changes in citizens' practices

    Time frame: Before and one month after the student citizens' assembly

    Participation in civic activities (vote, forum, petition signing...), frequency of participation in online and offline political conversation, self-confidence when expressing opinions on diet, trust in the university institution, perceived usefulness of citizens' assemblies, assessed by questionnaire

  5. Perception of the student citizens' assembly

    Time frame: Before and one month after the student citizens' assembly

    Motivations for participating in the student citizens' assembly, expectations on the role of this assembly, satisfaction with the proposals of the assembly, perceived quality of deliberations, assessed with an ad-hoc questionnaire

  6. Academic-related data

    Time frame: Before the student citizens' assembly

    Study level (undergraduate, post-graduate, PhD student) and discipline

  7. Changes in dietary habits and eating practices

    Time frame: Before the student citizens' assembly

    Changes in the interpretation of the term 'eating well,' understanding of the food system and its environmental impact, dietary habits and eating practices, barriers to sustainable diet, evaluated through semi-structured interviews

  8. Socioeconomic status

    Time frame: Before the student citizens' assembly

    Scholarship status

  9. Employment

    Time frame: Before the student citizens' assembly

    Employment status and weekly duration of job activities

  10. Demographic characteristics

    Time frame: Before the student citizens' assembly

    Gender, accomodation type, commuting time between home and place of study, household cooking facilities
