Shopping 'may improve health'

By Helen Briggs Health reporter, BBC News

Shopping prolongs life, at least for the over 65s in Taiwan, according to

research.

Even after adjusting for factors like physical and mental infirmity, men and

women who shopped daily lived longer than those who shunned retail therapy, say

scientists.

Shopping may provide companionship, exercise and an opportunity to maintain a

healthy diet, they report in the Journal of Epidemiology & Community Health.

A leading UK expert said the findings "made sense" since shopping involves

physical activity, social interaction and keeping mentally active.

In the study, published online in the academic journal, researchers led by Dr

Yu-Hung Chang of the Institute of Population Health Sciences, Taiwan, studied

nearly 2,000 men and women aged 65 and over who lived in their own homes.

They found those who shopped regularly lived longer than those who shopped just

once a week or less, even after adjusting for factors such as physical

limitations and cognitive decline.

The data

Taiwanese researchers studied 1,850 people aged 65 plus
All were living independently at home
During a survey in 1999-2000 they were asked how often they went shopping
The team tracked how long they lived by linking individuals to national death

registries between 1999 and 2008

Those who shopped daily were 27% less likely to die than those who shopped

infrequently, with the biggest effect seen in men

They acknowledge that shopping could be a marker for those in good health to

begin with, but suggest shopping itself may improve health.

"Shopping is often for pleasure with the potential to increase psychological

wellbeing," they conclude.

"Compared to other types of leisure-time physical activity, like formal

exercise, which usually requires motivation and sometimes professional

instruction, shopping activity is easier to undertake and maintain."

David Oliver, visiting professor of medicine for older people at City

University, London, said the findings "made sense".

He told the BBC: "What the Taiwanese researchers have shown is that continuing

to shop is independently predictive of better well-being and longer life.

"Shopping is going to involve physical activity, social interaction with other

shoppers and because it's quite a complex task it's going to keep you mentally

active.

"It makes sense that it would be a predictor of better physical and

psychological well-being."
