The students body composition will be assessed using impedance metric variables.The fat mass metric represents the total amount of body fat. It's often expressed in kilograms or as a percentage of total body weight. The measure will be recorded at different time frame:

• Pre-interventional measure at week 1: before any involvement in the modules (for the control and interventional groups).
• Post-interventional measure at week 27 : after the modules (for the control and interventional groups).

Change = (Week 27 score - Week 1 score)

The students body composition will be assessed using impedance metric variables. Skeletal muscle mass refers to the total mass or amount of skeletal muscle tissue in the body. It's often expressed in kilograms or as a percentage of total body weight.

The measure will be recorded at different time frame:

• Pre-interventional measure at week 1: before any involvement in the modules (for the control and interventional groups).
• Post-interventional measure at week 27 : after the modules (for the control and interventional groups).

Change = (Week 27 score - Week 1 Score)

The students body composition will be assessed using impedance metric variables.The total body hydration metric represents the total amount of water present in the body, including intracellular and extracellular water compartments. It's often expressed in liters or as a percentage of total body weight. The measure will be recorded at different time frame:

• Pre-interventional measure at week 1: before any involvement in the modules (for the control and interventional groups).
• Post-interventional measure at week 27 : after the modules (for the control and interventional groups).

Change = (Week 27 score - Week 1 score)

The composite score will be the mean of two sub-scores :

1. A stress module specific score. Mean of the scores obtained at the three 100-mm VAS ranging from 0 (absolutely not) to 100 (completely) :

   • "Do you think the intervention has helped you to decrease your stress level?"
   • "Do you think the intervention allowed you to better manage the stressful events you encountered?"

2. A stress module general score. Mean of the scores obtained at the 100-mm VAS ranging from 0 (absolutely not) to 100 (completely) :

   • "Do you think the proposed goals were suitable for your daily life?"
   • "Do you think you can sustain the habit changes?"

Theses measures will be done at the session 3, i.e. approximately at week 9,11,10 for the first phase, at week 16,17,18 for the second phase and at week 24,25,26 for the third phase.

The composite score will be the mean of two sub-scores :

1. A sedentary behaviors and physical activity module specific score. Mean of the scores obtained at the three 100-mm VAS ranging from 0 (absolutely not) to 100 (completely) :

   • "Do you think the module has helped you increase your level of physical fitness?")
   • "Do you think the module has helped you increase your level of physical activity?")
   • "Do you think the module has helped you decrease your level of sedentary behaviours?"

2. A sedentary behaviors and physical activity module general score. Mean of the scores obtained at the two 100-mm VAS ranging from 0 (absolutely not) to 100 (completely) :

   • "Do you think the proposed goals were suitable for your daily life?"
   • "Do you think you can sustain the habit changes?"

Theses measure will be done at the session 3, i.e. approximately at week 9,11,10 (1st phase), 16,17,18 (2n phase), 24,25,26 (3rd phase).

The composite score will be the mean of two sub-scores :

1. A sleep module specific score. Mean of the scores obtained at the two 100-mm VAS ranging from 0 (absolutely not) to 100 (completely) :

   • "Do you think the module has helped you to improve your sleep?"
   • "Do you think the module has helped you to decrease your fatigue?"

2. A sleep module general score. Mean of the scores obtained at the two 100-mm VAS ranging from 0 (absolutely not) to 100 (completely) :

   • "Do you think the proposed goals were suitable for your daily life?"
   • "Do you think you can sustain the habit changes?"

Theses measure will be done at the session 3, i.e. approximately at week 9,11,10 for the first phase, at week 16,17,18 for the second phase and at week 24,25,26 for the third phase.

"Would you recommend a friend to participate in PROMESS?" The answer may be YES or NO. This will provide information on students' willingness to recommend the project and may represents their overall perception and appreciation of the project. This measure will be done during the post-interventional period at week 27 (for the control and interventional groups).

"Health behavior refers to all individual actions and habits that have an impact on health, including lifestyle choices, hygiene practices, diets, physical activity, sleep, use of substances such as tobacco and alcohol, stress management and compliance with medical recommendations. These behaviors play a crucial role in disease prevention, health promotion and overall well-being. Based on this definition, do you think that your participation at the PROMESS project has modified your health behaviors/actions?". The answer can be YES or NO.This measure will be done during the post-interventional period at week 27 (for the control and interventional groups).

If the student answers yes at the previous question ("Do you think that your participation at the PROMESS project has modified your health behaviors/actions?"), he/she will be asked: "For which behaviors do you think you have modified your habits/actions?". They may answer YES (positive changes), YES (negative change), NO (no change for this behavior) among a pre-established list of behaviors (stress, sleep, sedentary or physical activity behaviors). They may also declare additional different habits changes. This measure will be done during the post-interventional period at week 27 (for the control and interventional groups).
