Gambling and suicidal behaviours are major public health concerns among adolescents and young adults. There is limited research on how the impact of gambling on suicidal behaviours may vary by race. The researchers analyzed data from the Missouri Family Study (MOFAM). The results showed that gambling increased the risk of suicidal thoughts among Black youth, but not among White youth. Major depressive disorder and childhood sexual abuse predicted suicidal thoughts among Black youth. Major depressive disorder and alcohol use predicted suicidal thoughts among White youth. Gambling did not predict suicide attempts. Major depressive disorder and childhood sexual abuse increased the risk of suicide attempts, especially among youth at or under the age of 15. Males were less likely to report suicidal behaviours than females.
