Aging and health
This research group is a collaboration between the Division of Physiotherapy and the Aging Research Center (ARC) at Karolinska Institutet.
We study health in older adults, with special focus on physical performance, physical activity/sedentary behavior and injurious falls. Our goals are to increase knowledge regarding:
- The complex interactions between biological, demographic, and social factors, chronic diseases, and lifestyle that may explain the development of poor health in old age (e.g., disability, injurious falls)
- The effect of sedentary behavior and physical activity patterns on health in old age
Our research combines large population-based studies, register data and clinical studies. In the population-based studies, we use objective instruments to assess physical activity and sedentary behavior, which permits a more valid and detailed examination than previously possible in population-based studies of older adults.
- A multifactorial approach to injurious falls in older adults—identifying levels of risk, sex differences, and functional trajectories
- Injurious falls in older adults: identifying people who may be targets for primary interventions—further development of the First-time Injurious Falls (FIF)-tool
- Harmful sitting in old age
- Social Health And Reserve in the Dementia patient journey (SHARED)
