Alcohol is an increasingly important risk factor in the global burden of disease. The acute harms experienced and persistence of drinking patterns established in adolescence motivate investigating influences on youth drinking. The aim is to examine association between heavier drinking in young people and their choice of beverage type, purchase outlet and price.
A nationally representative sample of New Zealand drinkers (N = 1056) aged 16-19 years recruited using random digit dialling was surveyed in 2012 as part of the International Alcohol Control study. Typical quantities consumed and frequency of alcohol consumption categorised respondents into lower, medium and heavier consumption groups. Beverage choice, prices paid and on or off-premise purchase were related to consumption using univariate analysis. Logistic analysis was used to examine multivariate factors predicting membership of consumption groups.
Twenty percent of the sample consumed six or more drinks at least once a week, increasing to 1 in 4 for those 18 years and older. Heavier drinkers consumed more alcohol in the form of ready to drinks (RTD) especially high-potency RTDs. Lower consumers drank greater proportion of wine. Heavier drinkers paid less than medium consumers who paid less than lower consumers. High-potency RTDs were cheaper per unit of alcohol than other beverages and chosen by heavier drinkers resulting in lower prices.
Heavy consumption of alcohol remains common in New Zealand young drinkers. Heavier drinkers paid less to purchase alcohol and consumed more alcohol in the form of high-potency RTDs.

酒精在全球疾病负担中是一个日益重要的风险因素。青少年饮酒所经历的急性危害以及饮酒模式的持续存在促使人们研究影响青少年饮酒的因素。目的是研究年轻人饮酒量较大与其饮料类型选择、购买场所和价格之间的关联。
作为国际酒精控制研究的一部分，2012年对通过随机数字拨号招募的16 - 19岁新西兰饮酒者的全国代表性样本（N = 1056）进行了调查。根据饮酒的典型量和饮酒频率，将受访者分为低、中、高饮酒量组。使用单变量分析将饮料选择、支付价格以及店内或店外购买情况与饮酒量相关联。采用逻辑分析来研究预测饮酒量组归属的多变量因素。
20%的样本每周至少有一次饮用六杯或更多酒，18岁及以上人群这一比例增至四分之一。饮酒量较大者饮用更多即饮型饮料（RTD），尤其是高酒精度的RTD。饮酒量较低者饮用葡萄酒的比例更高。饮酒量较大者支付的价格低于中等饮酒量者，中等饮酒量者支付的价格低于饮酒量较低者。每单位酒精含量的高酒精度RTD比其他饮料便宜，且饮酒量较大者选择购买，这导致了较低的价格。
在新西兰年轻饮酒者中，大量饮酒现象仍然普遍。饮酒量较大者购买酒精支付的价格更低，且以高酒精度RTD的形式饮用更多酒精。[沃尔M、卡斯韦尔S、叶L - C。饮酒量较大的年轻人购买集中在低价饮料：对政策的影响。《药物与酒精评论》2017；36：352 - 358]
