Glasgow University researchers have analysed data from 6,574 people who participated in the 2003 Scottish health Survey.
Researchers found five main factors which were the largest contributors in richer countries, smoking, drinking, poor diet, physical inactivity and obesity. The report found that a huge 97% of Scottish people had at least one of these risk factors.
55% of the population had three or more and 20% had four or all of the risk factors with poverty largely increasing the risk.
Author of the study Dr David Conway has said the Scottish population is living dangerously and it is a huge concern that almost the entire adult population has at least one behavioural risk factor.
“Our analysis shows that around two-thirds of the Scottish population is overweight or obese, a similar proportion are not sufficiently physically active, and most people have a poor diet.”
