Exposure to gambling promotions and gambling behaviours in Australian secondary school students

BACKGROUND: Young people’s gambling behaviours are associated with a range of individual, interpersonal and community factors. This study explored the association between exposure to types of gambling advertising and promotions and adolescent gambling behaviours. METHODS: Students from two states answered gambling questions as part of the 2017 Australian Secondary Students’ Alcohol and Drug (ASSAD) Survey. Students reported gambling behaviours (gambling in the last month, types of gambling activities), exposure to gambling promotions during the last 30 days (e.g. ads for gambling on TV, online, live studio crosses), and were assessed for problem gambling. Principal Component Analysis suggested four groups of gambling promotion exposure. Logistic regression analyses examined the association between gambling promotion exposure and student gambling, engagement in hard gambling activities in the last month, and problem or at risk gambling, controlling for a range of student characteristics. RESULTS: Most students (81%) had been exposed to some form of gambling promotion or advertisement in the last month, most commonly TV, social media and sporting event advertisements. Exposure to online gambling ads (including websites, pop-ups on websites, and social media) in the last month was significantly associated with gambling in the last month, and being classified as an at risk or problem gambler; but not with participating in hard gambling activities. After adjusting for exposure to gambling advertising across categories, no other advertising exposure types were associated with adolescent gambling behaviours. CONCLUSIONS: Study findings point to the need to impose restrictions on gambling advertisements and promotions, particularly those presented online.
