Sedentary Behavior Interventions in Older Adults
Summary
Sedentary behaviour, characterised by prolonged sitting or reclining with low energy expenditure, has emerged as a distinct risk factor for a range of adverse health outcomes in older adults, including sarcopenia, frailty, cardiovascular disease and declines in cognitive and mental health. Interventions designed to reduce total sedentary time or to interrupt prolonged bouts of sitting have employed a combination of behavioural, environmental and technological strategies. Common approaches include goal setting, action planning and tailored feedback delivered through education workbooks, one‐to‐one coaching or peer support. Wearable activity monitors and self‐monitoring tools enhance awareness of sitting patterns and prompt breaks in sedentary time. Remote delivery platforms, such as telehealth sessions, have increased accessibility for older adults with mobility limitations or living in rural and underserved areas. Community‐based programmes often integrate light‐intensity physical activity breaks into daily routines and promote age‐friendly environments that facilitate incidental movement. Collectively, these interventions aim to preserve functional independence, enhance muscle strength and reduce disability, with growing evidence that even modest reductions in daily sitting are linked to improvements in physical performance and quality of life.

Sedentary Behavior Interventions in Older Adults publication trend
The graph below shows the total number of articles in sedentary behavior interventions in older adults across all publications each year (not limited to Nature Index journals).
Technical terms
Sedentary behaviour: Any waking activity characterized by low energy expenditure (<1.5 METs) in a sitting or reclining posture.
Sarcopenia: Age‐related loss of skeletal muscle mass and strength, contributing to functional decline.
Frailty: A geriatric syndrome marked by diminished physiological reserves and increased vulnerability to stressors.
COM-B model: A theoretical framework positing that behaviour is influenced by capability, opportunity and motivation.
Self‐monitoring: A behaviour change technique whereby individuals track their own actions to promote awareness and facilitate goal attainment.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
