Bad behaviour and problem gambling often go hand-in-hand in teenage boys. Researchers at the University at Buffalo in New York studied 2,274 people between the ages of 14 and 21. They found that for 14 and 15 year-olds the odds of being a risky or problem gambler increased by 80% with each additional symptom of conduct disorder. However, as the participants got older the link weakened and for 20 and 21 year-olds there was no link between problem behaviour and gambling. Female adolescents were much less likely to behave badly or indulge in problem gambling. Overall the study found that those children who didn't behave badly had a 5% risk of problem gambling whereas those who did behave badly had a 23% risk.
