1 Drinking behaviours are defined as binge drink (usually having five or more alcoholic drinks per session); frequently drink (usually drinking at least two or more days each week) and drink in public settings (including drinking in streets, parks, pubs and clubs and excluding drinking at home, in friends' houses and on special occasions with family and friends). "Any drinking risk" and "all drinking risks" are composite variables calculated as having any one of the three individual risk factors and having all three risk factors respectively. Logistic regression was undertaken in STATA and utilised appropriate corrections for cluster sampling (see methods). Sample sizes vary as individuals not answering all questions included in the logistic regression analysis were excluded from the final model. AOR = Adjusted Odds Ratio. Ref = Reference category.
