CHICAGO (March 14, 1999 4:40 p.m. EST http://www.nandotimes.com) -
Babies whose mothers smoke while they're pregnant could be at an
increased risk of growing up to be criminals, new research suggests.

Although such links have been studied in children and teenagers,
researchers say a study published in this month's Archives of General
Psychiatry is the first to examine the relationship between mothers who
smoke and their children's adult behavior.

While stopping short of saying that babies whose mothers smoked while
pregnant will become criminals, researchers say their findings are
significant.

"Our results support our hypothesis that maternal smoking during
pregnancy is related to increased rates of crime in adult offspring," the
authors wrote, adding that the results "suggest an additional critical reason
to support public health efforts aimed at improving maternal health
behaviors during pregnancy."

However an expert not involved in the study said there is not enough
research to say that prenatal smoking can be a risk factor for adult crimes.

The researchers from Emory University in Atlanta, the University of
Southern California and the Institute of Preventive Medicine in Denmark
based their findings on data for 4,169 males born in Copenhagen between
September 1959 and December 1961 and studied the men's arrest
histories at age 34.

The number of cigarettes their mothers had smoked during the third
trimester of pregnancy affected the men's arrests for nonviolent and violent
crimes as adults, even after factoring out other possible causes such as
alcohol use, divorce, income and home environment, researchers said in
the study, which was released Sunday.

Only one other risk factor - delivery complications - was found to be
significant.

Researchers found that more than a quarter of the men whose mothers had
the highest levels of smoking and delivery complications were arrested for
a violent crime as an adult.

Further study should be aimed at determining the effects of smoking on the
brain of developing fetuses and to see if specific agents in tobacco smoke
can be more directly linked to antisocial behavior, they said.

A spokeswoman for Patricia Brennan, the study's lead author and a
researcher at Emory's Department of Psychology, did not return a page
Sunday seeking comment.

But David Fergusson, a psychiatric epidemiologist at the Christchurch
School of Medicine in New Zealand, said there is not enough research to
add prenatal smoking to the list of established risk factor for adult crimes.

Fergusson, who wrote an editorial accompanying the article, said the study
did not rule out the possibility that genetics - not smoking - caused behavior
problems.

"Mothers who smoke during pregnancy are often young women who have
previous misconduct problems and there is quite an inheritability of
misconduct problems," Fergusson said in a telephone interview Sunday.
