Gambling among Swedish youth: Predictors and prevalence among 15- and 17-year-old students.

Gambling among Swedish students is a highly gendered activity: boys gamble more and more frequently than girls. Having consumed alcohol was associated with both less frequent and more frequent gambling among Grade 9 students while controlling for other variables. In Grade 9, heavy episodic drinking was only associated with less frequent gambling, not with frequent gambling. Among Grade 11 students, both alcohol consumption and heavy episodic drinking was associated with less frequent gambling but heavy episodic drinking was only associated with frequent gambling. Moreover, drug use was associated with less frequent gambling in Grade 11. Skipping classes was the only school factor that was found to be associated with less frequent gambling (Grade 11). Such factors as family satisfaction and two measurements of economic situation were not associated with gambling at all.
