Research problem and specific questionsAn increasing amount of teenagers are sleeping too little on school nights. In the short term, mental health as well as school performancesare affected. Further, it increases the risk of leaving school without approved grades and developing long-term health problems. It is therefore vital to buck this trend. The overall aim of this project is to advance our knowledge of effectiveness of two sleep promoting school-based programs (high- and low-intensity) in grade 7-8 which have the potential to prevent future depression.Does a school-based sleep intervention delivered at the classroom level on five occasions affect sleep length, perceived quality of sleep, and mental health? Are effects maintained at 1-year follow-up?Does pre-bedtime mobile-stop affect sleep duration, perceived sleep quality, and mental health? Are effects maintained at 1-year follow-up?Which program is most effective? We will compare the high vs low intensity program using the RE-AIM framework. Data and methodStudy design: Cluster randomized trial.Schools will be randomized to 1) Sleep curriculum, 2) Pre-bedtime mobile-stop, 3) control group.Students in grade 7-8 (age 13-15 years) will be invited to participate in the study.All classes in years 7 and 8 are randomized at the school level to intervention or control, so-called cluster randomization.  Conclusions about differences or effects are then drawn at the cluster level and not at the individual level. All students are asked about participation in the study, and for those who agree to participate, written informed consent from students and guardians is obtained.Plan for project realisationTwo municipalities (Piteå and Kumla) have already agreed to participate in the project. Discussions on potential participation are conducted with other municipalities (Örebro, Lund, Kristianstad and Hässleholm).  RelevanceThe project is important as it provides new and specific knowledge about the effects of sleep-promoting interventions on teenagers´ sleep habits and sleep problems, which can guide school health care work and have the potential to prevent negative consequences for students.

Older adults who are hospitalized because of acute medical illness often experience worsening of physical function, and the transition from hospital to home may pose an additional risk. Even relatively small amounts of exercise might mitigate the risk of physical impairment, emphasizing the importance of identifying efficient and easy-to-use exercise interventions for older hospitalized people.In this project, we aim to 1) to examine if a transitional care program consisting of walking and sit-to-stand exercises performed during acute hospitalization and as self-training at home has effect over usual care concerning physical function in people aged 75 years and older, 2) perform a process evaluation during the different phases of the project, and, 3) translate the knowledge into clinical practice.We will conduct a randomized controlled trial. Participants aged 75 years and older will be included consecutively from geriatric medical wards of two hospitals in Region Stockholm. The intervention starts at the hospital and continues at home six weeks after discharge. The primary outcome is the score on the Short Physical Performance Battery (SPPB) at three months after discharge. Secondary outcomes are SBBP at hospital discharge, and the number of hospital readmissions six months after discharge.The project will include a pilot study to explore the feasibility and optimize the research design, and a process evaluation to assess the quantity and quality of what was delivered and the role of context. In the final phase of the project, we will provide a description of the changes needed to translate the intervention into different settings, which will be helpful for further implementation.Most previous exercise intervention studies in older adults were performed either at the hospital or at home. Thus, the proposed transitional care project may provide a novel strategy to maintain or improve physical function in this frail and vulnerable group.
