Misleading claim
THE COMMON claim that stress causes heart disease might be misleading, according to a study of 5,600 men in Scotland. It found a lower incidence of heart disease and death in those most likely to say their lives were stressful.
And that men who thought they were under the most stress were more likely to report symptoms of ill health, including chest pain. Some had been admitted to hospital.
A naive analysis would apparently show that stress caused heart disease, said Professor John McLeod, clinical research fellow at Birmingham University's department of primary care and general practice, who led the study.
A more likely explanation was that people feeling the most stressed were more likely to seek medical attention.
Another possibility was that men claiming the most stress smoked and drank more and took less exercise, but tended to have better jobs. Other research has shown that the more affluent are healthier. Affluence probably explained why, "by most objective measures of heart disease, they were healthier".
