简要总结
Medical students are under a great deal of competitive pressure throughout their training. During their studies, medical students experience high levels of stress, sleep disorders and excessive physical inactivity. These feelings and behaviours are expected to significantly degrade their quality of life, health and performance.
The PROMESS project aims to increase students' quality of life and ultimately improve their medical performance. The project aims to improve students' ability to take care of themselves from a short and long term perspective.
Encouraging physical activity, reducing sedentary behaviors, reducing stress, fatigue and sleep troubles during their curriculum can promote a healthier lifestyle and reduce the risk of chronic health conditions in the future.
The study seeks to quantify the impact of a complex intervention based on 3 modules (stress, sleep, physical activity) on the quality of life and academic performance of 2nd cycle medical students. This study will also have a clear insight on the influence of the complex intervention on changes in stress, sleep, physical activity and sedentary behavior markers.
详细描述
Our project aims to help future healthcare professionals to adopt health-promoting behaviors during their studies in a preventive approach. This support will be provided through a multimodal intervention during their curriculum. Specifically, 4th and 5th-year students at the Faculty of Medicine of Lyon Est will have the opportunity to participate in the PROMESS project. Voluntary will be randomized into 2 arms (intervention and control). The control group will not receive any intervention. The intervention group will follow a preventive program based on three modules: sedentary behaviors reduction and physical activity promotion, stress management, and sleep improvement and fatigue reduction. This program will span 30 weeks. Both groups will be characterized through a pre- post paradigm multimodal measurement. At the end of this period, we expect improvements in terms of quality of life, physical and mental health, and performance in the interventional arm.
METHODS.
POPULATION. The population consists of 70 medical students, with 2/3 (n=45 students) assigned to the intervention group and 1/3 (n=25 students) to the control group.
PRE-INTERVENTION. From week 1 to 3. All students will undergo a two-hour session, during which, they will complete questionnaires on sedentary behavior and physical activity, stress, sleep and fatigue levels. Bioimpedance and Heart Rate Variability will be measure. Students will perform three physical fitness tests (vertical jump, maximal isometric strength, and endurance). Then, they will wear actimeters to record sleep, sedentary behaviors and physical activity levels during three weeks.
INTERVENTION. From week 5 to week 25. The intervention program aims to address three key aspects of well-being. The students in the intervention group will take part in three modules, one on stress, one on sleep and fatigue, and the other on sedentary behaviors and physical activity.

结局指标
主要结局
Quality of life. Change from pre-intervention in a composite score obtained at the Brief Quality Of Life questionnaire at the post-interventional measure at Week 27.
时间窗: Week 1 (Pre-intervention) and Week 27 (Post-intervention)
The students level of the quality of life is assessed four sub-scores of quality of life (i.e. physical health, psychic well-being, social relationship, environnement). The composite score is the mean of the 2 dimensions: physical health and psychological well-being. The measure will be done at different time frame: * Pre-intervention measure at week 1: before any involvement in the intervention (for the control and interventional groups). * Post-intervention measure at week 27 : after the intervention (for the control and interventional groups). Change = (Week 27 score - Week 1 score)
