Physical activity and Disability in Older Adults

Key Message

A structured physical activity intervention reduces reported severe mobility disability and difficulty on mobility tasks in older adults with functional limitations.


Manini, Todd M. et al. (2017). Effect of Physical Activity on Self-Reported Disability in Older Adults: Results from the LIFE Study. Journal of the American Geriatric Society.Published online 7 February 2017. DOI: 10.1111/jgs.14742


The study tests the hypothesis that a long-term structured, moderate intensity physical activity (PA) program is more effective than a health education (HE) program in reducing the risk of s elf-reported dependency and disability in basic activities of daily living (BADLs), disability in instrumental ADLs (IADL), and mobility disability.


Over an average follow-up of 2.6 years, the cumulative incidence of BADL dependency was 15.2% among PA and 15.1% among HE participants (HR = 1.0, 95% CI = 0.78-0.1.3). Intervention groups had similar rates of incident BADL disability, IADL disability and reported mobility disability. Reporting severe mobility disability (HR = 0.78, 95% CI = 0.64-0.96) and ratings of difficulty on mobility tasks were reduced in the PA group.
