LONDON, July 21 (UPI) -- Men in their early 20s still living at home with their parents are more violent than those who live independently, researchers in Britain found.
Researchers at Queen Mary, University of London, said this group of men makes up 4 percent of the male population in Britain, but they are responsible for 16 percent of all violent injuries in the last five years.
Jeremy Coid and Dr. Ming Yang surveyed more than 8,000 men and women, who answered questions about violent behavior over the past five years and mental health problems.
"Young adult men living at home in Britain are no longer influenced by parents to conform to standards of behavior expected of previous generations," Coid said in a statement.
"Violence outside of the home, mainly involving strangers, is the most common scenario and just one of a series of hedonistic and negative social behaviors such as hazardous drinking, drug misuse, sexual risk taking, and non-violent antisocial behavior."
In this study, the men who lived with their parents had more disposable income which may have partly explained why they had more problems with alcohol, the researchers said.
The findings are published in the Social Psychiatry and Psychiatric Epidemiology.
