This is Science Today. It's been known for years
that married people tend to live longer than those
who stay unmarried. Now a study from the University
of California, Berkeley shows that a happy marriage
makes for a healthier old age. Cenita Kupperbusch,
a doctoral candidate in psychology, says a long-term
study of aging couples proves that a good marriage
can be the best medicine-at least for men.
Kupperbusch: Husbands who had increases in marital satisfaction also had increases in their health. On the other hand, this was a positive relationship. So husbands who had decreases in marital satisfaction also showed decreases in health.
Narrator: The study followed 78 elderly couples over a period of thirteen years. Using surveys and observation, the researchers found a clear link between marital satisfaction and health. But Kupperbusch says that the reason for that link is not yet known.
Kupperbusch: We don't know that changes in marital satisfaction are necessarily causing changes in health but we know there is some relationship between those two. It could be that changes in health are causing changes in marital satisfaction.
