Study title and authors:
Physical activity and mortality related to obesity and functional status in older adults in Spain.
This paper can be accessed at: http://www.ncbi.nlm.nih.gov/pubmed/21146766
The study examined the association between change in leisure-time physical activity (LTPA) and mortality in older adults, and whether this association varied with obesity and functional limitations. Data was taken from 2732 people aged over 60 years. Changes in LTPA from 2001 to 2003 were linked to all-cause mortality from 2003 to 2009.
The study found:
(a) Compared with people who were continually sedentary from 2001 to 2003, those who increased their LTPA had 34% lower mortality.
(b) Compared with people who were continually sedentary from 2001 to 2003, those who were continually active had 45% lower mortality.
(c) The results did not differ for those with obesity or functional limitations.
Balboa-Castillo concluded: Increasing or maintaining leisure-time physical activity is associated with greater longevity in older adults, even those with obesity or functional limitations. Given the high frequency of these disorders, the current results suggest that most older adults can benefit from an active lifestyle.
