Job strain boosts risk of heart disease by 23%: Study
PARIS (AFP) - Workers who suffer job strain are 23 per cent more likely to have a heart attack than stress-free counterparts, but the risk is far smaller than smoking or a sedentary lifestyle, a large study published in The Lancet on Friday says.
"Job strain is associated with a small, but consistent, increased risk of experiencing a first CHD (coronary heart disease) event such as a heart attack," said Professor Mika Kivimaki, an epidemiologist at University College of London who led the probe.
The investigation seeks to shed light on an issue that has turned up confusing results, mainly because researchers have used different definitions and varying methods.
The new paper is a meta-analysis - an overview of 13 studies conducted between 1985 and 2006 in seven European countries that adopted the same approach: participants without CHD were first interviewed and their health was then monitored, for 7.5 years on average.
