Sydney - The odds are high that if one of your parents is addicted to gambling, you may be too, according to a new study of Australian twins.
Scientists have found that genes play a role in a number of addictions and gambling is no exception, the researchers said in their study published in the June issue of the Archives of General Psychiatry.
"Previous research in men showed that gambling addiction can run in the family," researchers Wendy Slutske of the University of Missouri, told reporters. "This study extends those finding to include women."
By studying identical and fraternal twins, Slutske and colleagues from the Queensland Institute of Medical Research in Brisbane, Australia, were able to tease out the different impacts of genetic and environmental factors on addiction.
The team asked more than 2 700 women and 2 000 men from the Australian Twin Registry questions about their gambling, and also questioned their friends.
