Although previous studies have suggested that greater community densities of alcohol sales outlets are associated with greater alcohol use and problems, the mechanisms are unclear. The present study examined whether density was associated with increased purchasing of alcohol by adolescents younger than the legal purchase age of 18 in Australia.
The number of alcohol outlets per 10,000 population was identified within geographic regions in Victoria, Australia. A state-representative student survey (N = 10,143) identified adolescent reports of purchasing alcohol, and multilevel modeling was then used to predict the effects for different densities of outlet types (packaged, club, on-premise, general, and overall).
Each extra sales outlet per 10,000 population was associated with a significant increase in the risk of underage adolescent purchasing. The strongest effect was for club density (odds ratio = 1.22) and packaged (takeaway) outlet density (odds ratio = 1.12). Males, older children, smokers, and those with substance-using friends were more likely to purchase alcohol.
One mechanism by which alcohol sales outlet density may influence population rates of alcohol use and related problems is through increasing the illegal underage purchasing of alcohol.
尽管先前的研究表明，酒精销售点的社区密度越大，与饮酒和问题的相关性就越大，但具体机制尚不清楚。本研究旨在检验澳大利亚青少年的酒精购买量是否与低于 18 岁法定购买年龄的社区酒精销售点密度增加有关。
在澳大利亚维多利亚州的地理区域内，确定了每 10000 人中有多少个酒精销售点。一项州代表性的学生调查（N=10143）确定了青少年购买酒精的报告，然后使用多层模型预测不同类型（包装、俱乐部、现场、普通和总体）销售点密度的影响。
每增加 10000 人中有一个额外的销售点，与未成年青少年购买酒精的风险显著增加有关。俱乐部密度（优势比=1.22）和包装（外卖）销售点密度（优势比=1.12）的影响最大。男性、年龄较大的儿童、吸烟者和有滥用物质的朋友的人更有可能购买酒精。
酒精销售点密度可能影响人群饮酒率和相关问题的一个机制是通过增加非法未成年购买酒精。
