Single, Free, But Not So Healthy?

Mar. 23 -- THURSDAY, June 14 (HealthDay News) -- Single life has its charms and freedoms, but adults who never marry may not live as long as their wedded peers, new research suggests.

While the protective effect of marriage on health and longevity has been pointed out before, newer research is zeroing in on the never-married folks. Staying single all your life may not be good for your health or your lifespan, University of California, Los Angeles researchers have found.

The team looked at the 1997 U.S. National Death Index and the 1989 National Health Interview Survey. In 1989, almost half of the people surveyed were married; about 10 percent were widowed; 12 percent divorced; 3 percent separated; 5 percent living with someone; and 20 percent had never married.

Compared with married people, those who had never been married were 58 percent more likely to have died at the end of the study's eight-year follow up period.

By comparison, those who were widowed were nearly 40 percent more likely to die during the follow-up than were married participants, while those who had been divorced or separated were 27 percent more likely to die.

Still, the UCLA researchers, who published the study in the Journal of Epidemiology and Community Health, said the findings can't prove cause and effect.

And other researchers say it could be a chicken-and-egg question. Does single status lead to lack of health, or "are they single because they are unhealthy?" asked Patrick Markey, an assistant professor of psychology at Villanova University in Pennsylvania. He and his wife, Charlotte Markey, a researcher at Rutgers University in New Jersey, have studied the topic of marriage's effects on health.

"Marriage, at least for males, has a huge benefit" on health, said Patrick Markey. He and his wife looked at more than 2,200 adults, all participants in the New Jersey Family Health Survey, and found that being married was associated with men being more "health proactive" -- practicing good health habits, such as seeing the doctor regularly for check-ups.
