Study: Bad marriage might literally hurt the heart

USA Today reports:

CHICAGO (AP) — A lousy marriage might literally make you sick.
Marital strife and other bad personal relationships can raise your risk for heart disease, researchers reported Monday.

What it likely boils down to is stress — a well-known contributor to health problems, as well as a potential byproduct of troubled relationships, the scientists said.

In a study of 9,011 British civil servants, most of them married, those with the worst close relationships were 34% more likely to have heart attacks or other heart trouble during 12 years of follow-up than those with good relationships. That included partners, close relatives and friends.

The study, in Monday's Archives of Internal Medicine, follows previous research that has linked health problems with being single and having few close relationships. In the new study, researchers focused more on the quality of marriage and other important relationships.

It seems just as likely to me that bad health ruins marriages. Or maybe smoking, trans fats, and obesity cause both divorce and heart disease. More research is needed.
