To describe the blood alcohol concentration (BAC) of adolescent homicide victims in Johannesburg, South Africa and to identify the victim and event characteristics associated with a positive BAC at the time of death.
Logistic regression of mortality data collected by the National Injury Mortality Surveillance System (NIMSS).
Johannesburg, South Africa.
A total of 323 adolescent (15-19 years) homicide victims for the period 2001-9 who had been tested for the presence of alcohol.
Data on the victims' BAC level, demographics, weapon or method used, scene, day and time of death were drawn from NIMSS.
Alcohol was present in 39.3% of the homicide victims. Of these, 88.2% had a BAC level equivalent to or in excess of the South African limit of 0.05 g/100 ml for intoxication. Multivariate logistic analysis showed that a positive BAC in homicide victims was associated significantly with the victim's sex [male: odds ratio (OR) = 2.127; 95% confidence interval (CI) = 1.012-4.471], victim's age (18-19 years: OR = 2.364; CI = 1.343-4.163); weapon used (sharp instruments: OR = 2.972; CI = 1.708-5.171); and time of death (weekend: OR = 3.149; CI = 1.842-5.383; night-time: OR = 2.175; CI = 1.243-3.804).
Excessive alcohol consumption is associated with a substantial proportion of adolescent homicides in Johannesburg, South Africa, and is more prevalent among male and older adolescent victims and in victims killed with sharp instruments over the weekends and during the evenings.
描述南非约翰内斯堡青少年凶杀案受害者的血液酒精浓度（BAC），并确定与死亡时 BAC 呈阳性相关的受害者和事件特征。
国家伤害死亡率监测系统（NIMSS）收集的死亡率数据的逻辑回归。
南非约翰内斯堡。
在 2001-9 年期间，共有 323 名接受过酒精检测的青少年（15-19 岁）凶杀案受害者。
从 NIMSS 中提取有关受害者 BAC 水平、人口统计学、使用的武器或方法、现场、死亡日期和时间的数据。
酒精存在于 39.3%的凶杀案受害者中。其中，88.2%的受害者的 BAC 水平相当于或超过南非醉酒限制的 0.05g/100ml。多变量逻辑分析表明，凶杀案受害者的 BAC 呈阳性与受害者的性别[男性：比值比（OR）=2.127；95%置信区间（CI）=1.012-4.471]、受害者的年龄（18-19 岁：OR=2.364；CI=1.343-4.163）、使用的武器（尖锐工具：OR=2.972；CI=1.708-5.171）和死亡时间（周末：OR=3.149；CI=1.842-5.383；夜间：OR=2.175；CI=1.243-3.804）显著相关。
在南非约翰内斯堡，青少年凶杀案中与大量的青少年凶杀案与过度饮酒有关，而且在男性和年龄较大的青少年受害者中更为普遍，在周末和晚上使用尖锐工具和夜间被杀的受害者中更为普遍。
