Marriage a Powerful Drug for Surviving Heart Surgery, But Supply Dwindling
Strong protective effect of marriage continues for up to five years following coronary artery bypass surgery; boomers
2012 – Prior research has shown married people tend to live longer. A new study, however, focused on just the survival rate after heart
surgery, and it found married adults – men and women - are three times more likely to survive the three months following the surgery.
"That's a dramatic difference in survival rates for single people, during the most critical post-operative recovery
period," says Ellen Idler, a sociologist at Emory University and lead author of the study, which appears in the March issue of the Journal
of Health and Social Behavior.
"We found that marriage boosted survival whether the patient was a man or a woman."
While the most striking difference in outcomes occurred during the first three months, the study showed that the strong
protective effect of marriage continues for up to five years following coronary artery bypass surgery.
Overall, the hazard of mortality is nearly twice as great for unmarried as it is for married patients about to undergo
"The findings underscore the important role of spouses as caregivers during health crises," Idler says. "And husbands
were apparently just as good at caregiving as wives."
Tying the knot has been associated with longer life since 1858, when William Farr observed that marriage protected
against early mortality in France. The evidence keeps accumulating that the widowed, never married, and divorced have higher risks of
mortality. Much of the research, however, has looked broadly across populations during an entire lifespan, or relies only on medical records.
"We wanted to zero in on a particular window of time: a major health crisis," Idler says, "and we wanted to add the
in-person element of patient interviews, in addition to the full record of their medical history and hospitalization."
The major study involved more than 500 patients undergoing either emergency or elective coronary bypass surgery. All of
the study subjects were interviewed prior to surgery. Data on survival status of the patients were obtained from the National Death Index.
While the data are inconclusive for what caused the striking difference in the three-month survival rate, the interviews
provided some possible clues.
"The married patients had a more positive outlook going into the surgery, compared with the single patients," Idler says.
"When asked whether they would be able to manage the pain and discomfort, or their worries about the surgery, those who
had spouses were more likely to say, yes."
Patients who survived more than three months were approximately 70 percent more likely to die during the next five years
if they were single.
An analysis of the data showed that smoking history accounted for the lower survival rates in the single patients over
this longer term.
"The lower likelihood that married persons were smokers suggests that spousal control over smoking behavior produces
long-term health benefits," Idler says.
When it comes to healing hearts, marriage may be powerful medicine, but it's in increasingly short supply, Idler says,
which does not bode well for aging baby boomers.
During the 1960s, 72 percent of all adults over the age of 18 were married. Today, only 51 percent of them are, a record
low. This is the lowest percentage ever, according to the Pew Research Center. (see below)
Marriage Continues Decline Since 1960: Pew
share of Americans ages 18 and older who are currently married has been declining for many decades, reaching a record low 51% in 2010... In 1960, 72%
of adults were currently married and 15% were never married.
The share of adults who were currently married dropped
to 51%, and the never married group increased to 28% in 2010. The proportion divorced or separated, 14% in 2010, is higher than it was in 1960...
Widows and widowers made up the remaining 6% of adults in 2010.
...Only 9% of adults ages 18-24 were married in 2010,
compared with 45% in 1960. ..Although most Americans in their mid-30s onward are married, the proportions have declined notably since 1960 -Red complete report by
