OBJECTIVES
We estimated the effects on assault rates of lowering the minimum alcohol purchasing age in New Zealand from 20 to 18 years. We hypothesized that the law change would increase assaults among young people aged 18 to 19 years (the target group) and those aged 15 to 17 years via illegal sales or alcohol supplied by older friends or family members.
METHODS
Using Poisson regression, we examined weekend assaults resulting in hospitalization from 1995 to 2011. Outcomes were assessed separately by gender among young people aged 15 to 17 years and those aged 18 to 19 years, with those aged 20 and 21 years included as a control group.
RESULTS
Relative to young men aged 20 to 21 years, assaults increased significantly among young men aged 18 to 19 years between 1995 and 1999 (the period before the law change), as well as the postchange periods 2003 to 2007 (incidence rate ratio [IRR] = 1.21; 95% confidence interval [CI] = 1.05, 1.39) and 2008 to 2011 (IRR = 1.20; 95% CI = 1.05, 1.37). Among boys aged 15 to 17 years, assaults increased during the postchange periods 1999 to 2003 (IRR = 1.28; 95% CI = 1.10, 1.49) and 2004 to 2007 (IRR = 1.25; 95% CI = 1.08, 1.45). There were no statistically significant effects among girls and young women.
CONCLUSIONS
Lowering the minimum alcohol purchasing age increased weekend assaults resulting in hospitalization among young males 15 to 19 years of age.
目的
我们评估了将新西兰最低法定饮酒年龄从 20 岁降至 18 岁对袭击率的影响。我们假设，通过非法销售或由年长朋友或家人提供的酒精，该法律变更将增加 18 至 19 岁（目标群体）以及 15 至 17 岁青少年的袭击事件。
方法
使用泊松回归，我们检查了 1995 年至 2011 年期间因周末袭击导致住院的情况。在 15 至 17 岁和 18 至 19 岁的年轻人中，分别按性别评估结果，将 20 岁和 21 岁的年轻人作为对照组。
结果
与 20 至 21 岁的年轻男性相比，1995 年至 1999 年（法律变更前）以及变更后的 2003 年至 2007 年（发病率比 [IRR] = 1.21；95%置信区间 [CI] = 1.05, 1.39）和 2008 年至 2011 年（IRR = 1.20；95% CI = 1.05, 1.37）期间，18 至 19 岁的年轻男性的袭击事件显著增加。对于 15 至 17 岁的男孩，在变更后的 1999 年至 2003 年（IRR = 1.28；95% CI = 1.10, 1.49）和 2004 年至 2007 年（IRR = 1.25；95% CI = 1.08, 1.45）期间，袭击事件也有所增加。在女性和年轻女性中，没有统计学意义上的显著影响。
结论
降低最低法定饮酒年龄增加了 15 至 19 岁青少年周末袭击导致住院的事件。
