Aging and health – physical performance, sedentary behavior and injurious falls

This research group is a collaboration between the Division of Physiotherapy and the Aging Research Center (ARC).

Research focus

Focus is on physical performance, sedentary behavior and injurious falls in older adults. Our goals are to increase knowledge regarding:

1) The complex interactions between biological, demographic, and social factors, chronic diseases, and lifestyle that may explain the development of poor health in old age, with a special focus on physical disability and injurious falls.

2) To what extent the increased life expectancy in the last century has resulted in healthy years or years lived in poor health and disability.

3) How and which patterns of sedentary behavior are linked to poor health among older adults.

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.

Research projects

  • A multifactorial approach to injurious falls in older adults—identifying levels of risk, sex differences, and functional trajectories
  • Temporal trends in health and functioning among older adults
  • 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—too much or too long? Health effects of sedentary behavior
