Active older adults have a higher quality of life, study suggests
A reduction in the amount of time spent physically active when adults are over sixty years old is linked to lower quality of life, a Cambridge study of almost 1,500 adults has shown. The same was also true for increases in the amount of sedentary time, such as watching TV or reading. The researchers say this highlights the need to encourage older adults to remain active.
A team led by researchers at the University of Cambridge examined activity levels among 1,433 participants aged 60 and above using accelerometers. Alongside this, the team also looked at health-related quality of life. Participants were given a score between 0 (worst quality of life) and 1 (best) based on their responses to a questionnaire. Lower quality of life scores is linked with an increased risk of hospitalization, worse outcomes following hospitalization, and early death.
Those individuals who did more moderate-to-vigorous physical activity and spent less time sedentary at their first assessment had a higher quality of life later on. An hour a day spent more active was associated with a 0.02 higher quality of life score.
For every minute a day less of moderate-to-vigorous physical activity measured six years after the first assessment, quality of life scores dropped by 0.03. This means that an individual who spent 15 minutes a day less engaged in such activity would have seen their score drop by 0.45.
Increases in sedentary behaviors were also associated with poorer quality of life – a drop in the score of 0.012 for every one-minute-a-day increase in total sedentary time six years after the first measurement. This means that an individual who spent 15 minutes a day more sitting down would have seen their score drop by 0.18.
