AIMS An integral part of the World Health Organization (WHO) plan to reduce suicide by 10% by 2020 is to identify areas and demographic groups, which should be priority target groups for preventive activities. This study aimed to present the demographic differences between victims of suicide by hanging in the Warsaw metropolitan area, in Poland, by examining the sobriety of victims. METHODS Data for analysis were obtained from the documentation of the Department of Forensic Medicine (DFM) at the Medical University of Warsaw (MUW). The retrospective analysis included 358 out of 466 victims of suicides by hanging in the Warsaw metropolitan area, in Poland, recorded in the DFM documentation covering 2011-2013. The data gathered included age, gender, the cause of death, a post-mortem examination as well as the level of ethanol in the blood and muscles of victims. RESULTS In both groups, men accounted for a larger percentage of victims than women, P = 0.068. In the no-alcohol group, the victims were older than in the alcohol group (47.52 ± 19.21 vs. 40.88 ± 12.77) (P < 0.001). The majority of the studied population were victims aged 25-34 (22.90%), mainly men (20.95%). Young men were also the largest group among victims in the alcohol group (28.33%). The most numerous age group among no-alcohol group were older victims aged 55-64 (19.10%), especially men (16.29%). CONCLUSION Regardless of sobriety, men were the largest group of suicide victims in the study population, which means that men die suicide more often than women. Differences in gender proportions are related to age. In the studied population, it was primarily young victims, mainly men. These are the groups that should be priority target groups for preventive activities aimed at reducing the number of suicides. The presence of ethanol in more than half of the victims of suicide in the study population indicates that alcohol is an important suicidal risk factor.

悬挂在波兰的酒精中毒和自杀。

目标到2020年，世界卫生组织（WHO）计划将自杀减少10％的一个不可分割的部分是确定地区和人口群体，这应该是预防活动的优先目标群体。这项研究的目的是通过考察受害者的清醒程度，将其挂在波兰的华沙都会区，以显示自杀受害者之间的人口差异。方法分析数据来自华沙医科大学法医学系（DFM）的文件。回顾性分析包括2011年至2013年DFM文档中记录的466名自杀受害者中的358名悬挂在波兰华沙大都市。收集的数据包括年龄，性别，死亡原因，验尸以及受害者血液和肌肉中的乙醇含量。结果在两组中，男性在受害者中所占的比例均高于女性，P = 0.068。在无酒精饮料组中，受害者的年龄比在酒精饮料组中的年龄大（47.52±19.21对40.88±12.77）（P <0.001）。研究人群中大多数是25-34岁的受害者（22.90％），主要是男性（20.95％）。在酗酒者中，年轻人也是最大的受害者（28.33％）。在无酒精人群中，年龄最大的是年龄在55-64岁之间的老年受害者（19.10％），尤其是男性（16.29％）。结论不论清醒，男性是研究人群中自杀受害者的最大群体，这意味着男性比女性死于自杀的可能性更高。性别比例的差异与年龄有关。在研究人群中 主要是年轻的受害者，主要是男人。这些群体应成为旨在减少自杀人数的预防活动的优先目标群体。在研究人群中超过一半的自杀受害者中存在乙醇，这表明酒精是重要的自杀危险因素。
