To assess the association between alcohol use and victimization by homicide in individuals autopsied at the Institute of Legal Medicine in São Paulo, Brazil.
Cross-sectional study.
Excessive consumption of alcohol is a serious public health issue and a major factor in triggering violent situations, which suggests a strong association between alcohol ingestion and becoming a victim of homicide.
Data from 2042 victims of homicides in 2005 were obtained from medical examiner reports.
The victim's gender, age, ethnicity and blood alcohol concentration (BAC) were collected. The method of death and homicide circumstances, as well as the date, time and place of death were also studied.
Alcohol was detected in blood samples of 43% of the victims, and mean BAC levels were 1.55 +/- 0.86 g/l. The prevalence of positive BAC levels was higher among men (44.1%) than women (26.6%), P < 0.01. Firearms caused most of the deaths (78.6%), and alcohol consumption was greater among victims of homicide by sharp weapons (P < 0.01). A greater proportion of victims with positive BAC were killed at weekends compared to weekdays (56.4 and 38.5%, respectively; P < 0.01), and the correlation between homicide rates and the average BAC for the central area of the city was positive (r(s) = 0.90; P < 0.01).
These results highlight alcohol as a contributing factor for homicide victimization in the greatest urban center in South America, supporting public strategies and future research aiming to prevent homicides and violence related to alcohol consumption.
评估在巴西圣保罗法医学研究所进行尸检的个体中，酒精使用与凶杀受害之间的关联。
横断面研究。
过度饮酒是一个严重的公共卫生问题，也是引发暴力情况的主要因素，这表明酒精摄入与成为凶杀受害者之间存在很强的关联。
从 2005 年法医学报告中获取了 2042 名凶杀受害者的数据。
收集了受害者的性别、年龄、种族和血液酒精浓度（BAC）。还研究了死亡方式和凶杀情况，以及死亡日期、时间和地点。
在 43%的受害者的血液样本中检测到了酒精，平均 BAC 水平为 1.55 +/- 0.86 g/l。男性（44.1%）的阳性 BAC 水平患病率高于女性（26.6%），P < 0.01。火器导致了大多数死亡事件（78.6%），并且在使用尖锐武器的凶杀受害者中，酒精消耗更多（P < 0.01）。与工作日相比，周末有更多阳性 BAC 的受害者被杀害（分别为 56.4%和 38.5%；P < 0.01），并且城市中心的凶杀率与平均 BAC 之间存在正相关（r(s) = 0.90；P < 0.01）。
这些结果突出了酒精在南美洲最大城市中心的凶杀受害中的促成因素，支持了旨在预防与酒精消费相关的凶杀和暴力的公共策略和未来研究。
