Abstract Aims 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. Design Logistic regression of mortality data collected by the National Injury Mortality Surveillance System (NIMSS). Setting Johannesburg, South Africa. Participants A total of 323 adolescent (15–19 years) homicide victims for the period 2001–9 who had been tested for the presence of alcohol. Measurements Data on the victims’ BAC level, demographics, weapon or method used, scene, day and time of death were drawn from NIMSS. Findings 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). Conclusions 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.
