According to new research from the University of Rochester (USA) has found that happily married than single people survive after undergoing surgery 'by-pass' corononario, as recorded by the digital version of 'Health Psychology'.

Specifically, married people who undergo this procedure are three times more likely to survive for 15 years after surgery than single men.

"Good relationships help people survive," says the lead author and professor emeritus at the School of Nursing at the University of Rochester, Kathleen King.

In fact, the effect of satisfaction of marriage is "as important for survival after surgery 'by-pass' as are the more traditional risk factors, such as snuff consumption, obesity and hypertension," explains co-author of the study, professor of psychology at the University of Rochester, Harry Reis.

But marriage affects differently to men and women. For men, in general, marriage is linked to higher survival rates and the higher the satisfaction rate, the greater the survival. Meanwhile, for women, the quality of the relationship is more important. While unhappy marriages do not offer virtually no survival advantage for women, almost quadruple the satisfactory survival rate of a woman, the study said.

"Women need to feel satisfied in their relationships to reap a dividend of health," Reis said, adding that "the rewards of marital happiness is higher for women than for men."

Fifteen years after surgery, 83 percent of happily married women were still alive compared with 28 percent of women with an unhappy marriage and 27 percent of single women. The survival rate for the happy couple was also 83 percent, but even the not so happily married I was fine. Less satisfied men enjoyed a survival rate of 60 percent, significantly better than the rate of 36 percent of single men.

Marriage provides patients with a sustained motivation to take care of yourself and a powerful reason to "survive and maintain the relationship they like," concludes the researcher.
