Acute alcohol use is a proximal risk factor for suicide. However, the proportion of suicide deaths involving acute alcohol use has not been quantified in New Zealand. We sought to quantify and characterise the association between acute alcohol use and suicide.
Data for all suicides (≥15 years) between July 2007 and December 2020 were drawn from the National Coronial Information System. Acute alcohol use was defined as blood alcohol concentration (BAC) >50mg/100mL. Logistic regression was used to compare characteristics between suicide deaths with and without acute alcohol use.
Twenty-six point six percent of suicide deaths involved acute alcohol use. No difference in the association was found by sex (male AOR: 0.87 (95%CI: 0.74,1.02)). Ethnicity differences were identified (Māori AOR: 1.20 (95%CI: 1.01,1.42), Pacific AOR: 1.46 (95%CI: 1.10,2.00)). Those aged 15-54 years had similar risks of suicide involving acute alcohol use, with a lower association in older age groups.
Acute alcohol use was identified in approximately one quarter of suicides, with stronger associations in those of Māori and Pasifika ethnicity, and those aged <55 years. Acute alcohol use is a significant but modifiable risk factor for suicide in New Zealand.
急性酒精使用是自杀的一个近期风险因素。然而，在新西兰，涉及急性酒精使用的自杀死亡比例尚未量化。我们试图量化和描述急性酒精使用与自杀之间的关系。
从国家验尸信息系统中提取了 2007 年 7 月至 2020 年 12 月期间所有（≥15 岁）自杀事件的数据。急性酒精使用定义为血液酒精浓度（BAC）>50mg/100mL。使用逻辑回归比较有和无急性酒精使用的自杀死亡特征。
26.6%的自杀死亡涉及急性酒精使用。性别的关联没有差异（男性 AOR：0.87（95%CI：0.74，1.02））。确定了种族差异（毛利人 AOR：1.20（95%CI：1.01，1.42），太平洋岛民 AOR：1.46（95%CI：1.10，2.00））。15-54 岁年龄组自杀涉及急性酒精使用的风险相似，而年龄较大的年龄组关联较低。
大约四分之一的自杀涉及急性酒精使用，毛利人和太平洋岛民以及年龄<55 岁的人关联更强。急性酒精使用是新西兰自杀的一个重要但可改变的风险因素。
