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. conditions: Health Behavior conditions: Health-Related Behavior studyType: INTERVENTIONAL phases: NA allocation: RANDOMIZED interventionModel: PARALLEL interventionModelDescription: Randomized controlled clinical trial. Randomization into two groups: INTERVENTION group and CONTROL group. The INTERVENTION group will have the opportunity to follow a preventive remediation program based on 3 modules: stress management, sleep improvement and fatigue reduction, and sedentary behaviors reduction and physical activity promotion. The order of following the 3 modules will be randomized. The CONTROL group will not receive any intervention. primaryPurpose: HEALTH_SERVICES_RESEARCH masking: SINGLE maskingDescription: Assessors of pre and posttest measures will be blinded to the group allocation. whoMasked: OUTCOMES_ASSESSOR count: 70 type: ESTIMATED name: Stress management, sleep improvement and fatigue reduction, sedentary behaviors reduction and physical activity promotion. measure: Quality of life.
