         A reduction in the amount of time spent physically active when

   ==========================================================================   
   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.   
      
   Physical activity -- particularly when it is moderate-intensity and raises   
   your heart rate -- is known to reduce the risk of a number of diseases,   
   including heart disease, stroke, diabetes and cancer. The NHS recommends   
   that adults do at least 150 minutes of moderate-intensity activity or   
   75 minutes of vigorous- intensity activity a week. Older adults are also   
   recommended to break up prolonged periods of being sedentary with light   
   activity when physically possible, or at least with standing, as this   
   has distinct health benefits for older people.   
      
   A team led by researchers at the University of Cambridge examined   
   activity levels among 1,433 participants aged 60 and above using   
   accelerometers. The participants had been recruited to the EPIC (European   
   Prospective Investigation into Cancer)-Norfolk study.   
      
   Alongside this, the team also looked at health-related quality of life,   
   a measure of health and wellbeing that includes pain, ability to care   
   for yourself and anxiety/mood. 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 are linked with an increased risk of   
   hospitalisation, worse outcomes following hospitalisation, and early   
   death.   
      
   Participants were followed up an average of just under six years later   
   to look at changes in their behaviour and quality of life. The results   
   of the study are published in Health and Quality of Life Outcomes.   
      
   On average, six years after their first assessment, both men and women   
   were doing around 24 minutes less moderate-to-vigorous physical activity   
   per day. At the same time, the total sedentary time increased by an   
   average of around 33 minutes a day for men and around 38 minutes a day   
   for women.   
      
   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 behaviours were also associated with poorer quality   
   of life -- a drop in the score of 0.012 for everyone 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.   
      
   To put the results into a clinical context, a 0.1 point improvement   
   in quality of life scores has previously been associated with a 6.9%   
   reduction in early death and a 4.2% reduction in risk of hospitalisation.   
      
   Dr Dharani Yerrakalva from the Department of Public Health and Primary   
   Care at the University of Cambridge said: "Keeping yourself active and   
   limiting -- and where you can, breaking up -- the amount of time you   
   spend sitting down is really important whatever stage of life you're   
   at. This seems to be particularly important in later life, when it can   
   lead to potentially significant improvements to your quality of life   
   and your physical and mental wellbeing."  Because the team measured   
   physical activity and sedentary behaviour at different points of time,   
   they say they can be reasonably confident that they have shown a causal   
   link -- that is, that quality of life improves because people remain   
   more physically active, for example.   
      
   Dr Yerrakalva added: "There are several ways in which improvements in our   
   physical behaviours might help maintain a better quality of life. For   
   example, more physical activity reduces pain in common conditions   
   such as osteoarthritis, and we know that being more physically active   
   improves muscle strength which allows older adults to continue to care   
   for themselves.   
      
   Similarly, depression and anxiety are linked to quality of life, and can   
   be improved by being more active and less sedentary."  The EPIC-Norfolk   
   study is funded by the Medical Research Council and Cancer Research UK.
