People Who Are Prayed for Fare Better

Nov. 6, 2001 -- Here's more evidence that -- in medicine, as in all of
life -- prayer seems to work in mysterious ways. 

In one recent study, women at an in vitro fertilization clinic had higher
pregnancy rates when total strangers were praying for them. Another study
finds that people undergoing risky cardiovascular surgery have fewer
complications when they are the focus of prayer groups. 

The fertilization study -- conducted at a hospital in Seoul, Korea --
found a doubling of the pregnancy rate among women who were prayed for,
says Rogerio A. Lobo, MD, chair of Obstetrics and Gynecology at Columbia
University School of Medicine in New York City. His study appears in the
September issue of the Journal of Reproductive Medicine. 

"It's a highly-significant finding," Lobo tells WebMD. "I'm first to say
we don't know what this means." 

The randomized study involved 199 women who were undergoing in vitro
fertility treatments at a hospital in Seoul, Korea, during 1998 and 1999.
All women were selected for the study based on their similar age and
fertility factors, Lobo tells WebMD. 

Half the women were randomly assigned to have one of several Christian
prayer groups in the U.S., Canada, and Australia pray for them. A
photograph of each patient was given to "her" prayer group. While one set
of prayer groups prayed directly for the women, a second set of prayer
groups prayed for the first set, and a third group prayed for both groups.

Neither the women nor their medical caregivers knew about the study -- or
that anyone was praying for them. 

"We were very careful to control this as rigorously as we could," Lobo
tells WebMD. "We deliberately set it up in an unbiased way." That meant
not informing patients they were being prayed for, so it would not
influence the women's outcome. Whether the patients were praying for
themselves -- or if others were praying for them -- "we don't know," he

The women in the "prayed for" group became pregnant twice as often as the
other women, he says. 

"We were not expecting to find a positive result," says Lobo. Researchers
have re-analyzed the data several times, to detect any discrepancies --
but have been unable to find any, he says. 

Lobo admits there may be some "biological variable" that they have not
discovered, which could account for the high success rate among the
prayed-for women. He and his colleagues are already planning a follow-up
study also involving in vitro fertilization. 

The second study involves 150 patients -- all having serious heart
problems, all scheduled for a procedure called angioplasty, in which
doctors thread a catheter up into a clogged heart artery, open it up, and
insert a little device called a stent to prop it open. 

Patients who were prayed for during their procedure had far fewer
complications, reports lead author Mitchell W. Krucoff, MD, director of
the Ischemia Monitoring Laboratory at Duke University Medical Center and
the Durham Veterans Administration Medical Center in Durham, NC. 

His study appears in the current issue of the American Heart Journal. 

Krucoff enrolled 150 patients who were going to have the stent procedure,
and then randomly assigned them to receive one of five complementary
therapies: guided imagery, stress relaxation, healing touch, or
intercessory 'off site' prayer -- which meant they were prayed for by
others, or to no complementary therapy. 

All the complementary therapies -- except off-site prayer -- were
performed at the patient's bedside at least one hour before the cardiac

Seven prayer groups of varying denominations around the world --
Buddhists, Catholics, Moravians, Jews, fundamentalist Christians,
Baptists, and the Unity School of Christianity -- prayed for specific
patients during their procedures. 

Each prayer group was assigned names, ages, and illnesses of specific
patients they were to pray for. None of the patients, family members, or
staff knew who was being prayed for. None of the patient-prayer group
matchings were based on denomination. 

"This was a very rigorously controlled study, just as we would look at any
therapeutic -- a new cardiovascular drug, a new stent -- and see the
results in terms of patients' outcomes," Krucoff tells WebMD. The goal was
to determine which therapies warranted further study in a bigger trial. 

Those in the "prayed for" group had fewer complications than any of the
patients, including those receiving other complementary therapies, he
says. "Although it's not statistical proof, it's not certainty, it is
suggestive -- to the point that we've already begun a phase II trial." 

He has already enrolled more than 300 people in a phase II study. 

Why did prayer produce the best outcome? "There are no satisfactory
mechanistic explanations," he says. That's why studies that measure
patients' outcomes are best for this kind of study, he says. Even if you
don't understand why it's happening, at least you have something to
measure -- how the patient did." 

Both studies are "well-controlled," preliminary trials "providing more
evidence that there's something to it all," says Blair Justice, PhD,
professor of psychology and psychobiologist (mind-body medicine) at the
University of Texas School of Public Health in Houston. 

Justice, who has followed prayer research for several decades, reviewed
the reports for WebMD. 

"Research into prayer has been going on a lot longer than is reflected in
mainstream journals," Justice tells WebMD. "Since the 1980s, there have
been several well-controlled prospective studies, good evidence that this
wasn't some product of a good imagination." 

Some of the studies conducted in Europe involved nonhuman organisms --
enzyme cells, bacteria, plants, animals -- which could not be affected by
other complicating factors, including faith. Groups were assigned to pray
for their growth; then the prayers were reversed, and people were praying
against growth. Each time, the plants responded according to the focus of
the prayers. 

"There seems to be something to it," he says. 

While current technology does not allow researchers to understand the
mechanism behind prayer -- what makes it work -- it's much like gravity
and other natural phenomena that were considered mysterious forces by
earlier cultures, Justice tells WebMD. 

"Keppler was accused of being insane when he said tides were due to the
tug of lunar gravity, even Galileo considered it to be ravings of a
lunatic -- until Marconi proved the theory," he says.

"It's just like anything else, you don't have to believe in it for prayer
to have an effect," says Justice.
