Job stress increases the risk of
heart disease, but living a healthy lifestyle can significantly reduce that
risk, a new study says.
Mika Kivimaki and colleagues pooled
individual-level data for more than 100 000 men and women in 7 prospective
cohort studies.
Their lifestyles were rated in one
of three categories -- healthy, moderately unhealthy or unhealthy -- based on 4
lifestyle risk factors: current smoking, physical inactivity, heavy drinking
and obesity.
The researchers found that
participants who reported job strain and a healthy lifestyle (no lifestyle risk
factors) at baseline had about half the incidence of coronary disease* as those
with job strain and 1 or more lifestyle risk factors.
"The risk of coronary artery
disease was highest among participants who reported job strain and an unhealthy
lifestyle; those with job strain and a healthy lifestyle had about half the
rate of this disease," Dr. Kivimaki, of the department of epidemiology and
public health at University College London
Evidence from randomized controlled
trials has shown that lifestyle changes such as weight loss and stopping
smoking can reduce the risk of disease.
"In addition to stress
counselling, clinicians might consider paying closer attention to lifestyle
risk factors in patients who report job strain," the authors conclude.
