A happy marriage can triple the long-term chances of surviving heart bypass surgery, according to a study.
Research by the University of Rochester found that 83 per cent of happily married women survive the 15 years that follow such operations, compared to 27 per cent of unmarried women.
Of the married men studied, 83 per cent survived, while 36 per cent of unmarried men lasted the duration. The biggest difference in the sexes came in regards to those in unhappy marriages, with 28 per cent of women living for the 15 years that followed, compared to 60 per cent of men.
Harry Reis, professor of psychology at the university and co-author of the study, said happy marriage is "every bit as important to survival after bypass surgery as more traditional risk factors like tobacco use, obesity and high blood pressure".
A recent study by Ohio State University found that getting married can have an effect on a person's health, with results showing a 48 per cent higher risk of large weight gain in the first two years of a woman's marriage.
