It is well recognized that both acute and chronic alcohol use are among the major behaviorally modifiable factors that are associated with suicidal behavior. There is suggestive evidence that binge drinking pattern, i.e. excessive consumption of strong spirits results in quicker and deeper level of intoxication, increasing the propensity for alcohol-related suicide. Although alcohol seems to be an important contributor to the burden of violent mortality in Belarus, little systematic research has been undertaken on its impact on suicide mortality in this country. The aim of the present study was to address this particular deficit by using aggregate-level data on the suicide and alcohol poisoning rates from 1979 to 2007.
Trends in suicides and alcohol poisoning mortality rate (as a proxy for binge drinking) from 1979 to 2007 were analyzed employing an ARIMA analysis in order to assess bivariate relationship between the two time series.
According to Bureau of Forensic Medicine autopsy reports the suicide rate increased by 41.2%, and fatal alcohol poisoning rate increased 2.1 times in Belarus. Alcohol in blood was found in 62% suicide victims for the whole period, with the minimum figure 49.3% in 1988 and maximum 68.5% in 1981. Alcohol-related suicides were more affected by the restriction of alcohol availability during the anti-alcohol campaign: between 1984 and 1986 the number of BAC-positive suicide cases drop by 54.2%, while number of BAC-negative suicides decreased by 7.1%. The results of time-series analysis indicated a statistically significant relationship between fatal alcohol poisoning rate and total suicides number, as well as number of BAC-positive suicides.
The results of the present study, as well as findings from other settings indicate that a restrictive alcohol policy can be considered as an effective measure of suicide prevention in countries where rates of both alcohol consumption and suicide are high.
人们普遍认识到,急性和慢性酒精使用都是与自杀行为相关的主要行为可改变因素。有证据表明,狂饮模式,即过量饮用烈性酒,会导致更快且更深程度的醉酒,增加与酒精相关的自杀倾向。尽管酒精似乎是白俄罗斯暴力死亡率负担的一个重要因素,但该国对其对自杀死亡率的影响进行的系统研究很少。本研究的目的是通过使用1979年至2007年自杀和酒精中毒率的总体数据来弥补这一特定不足。
采用自回归积分滑动平均(ARIMA)分析方法,分析1979年至2007年自杀和酒精中毒死亡率(作为狂饮的代理指标)的趋势,以评估这两个时间序列之间的双变量关系。
根据法医学局的尸检报告,白俄罗斯的自杀率上升了41.2%,致命酒精中毒率上升了2.1倍。在整个时期,62%的自杀受害者血液中检测到酒精,1988年的最低比例为49.3%,1981年的最高比例为68.5%。在反酒精运动期间,酒精相关自杀受酒精供应限制的影响更大:1984年至1986年期间,血液酒精含量(BAC)呈阳性的自杀案件数量下降了54.2%,而BAC呈阴性的自杀案件数量下降了7.1%。时间序列分析结果表明,致命酒精中毒率与自杀总数以及BAC呈阳性的自杀数量之间存在统计学上的显著关系。
本研究结果以及其他研究结果表明,在酒精消费率和自杀率都很高的国家,限制性酒精政策可被视为预防自杀的有效措施。
