title: Alcohol consumption in adolescent homicide victims in the city of Johannesburg, South Africa.
abstract: OBJECTIVE
  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.
  
  
  METHODS
  Logistic regression of mortality data collected by the National Injury Mortality Surveillance System (NIMSS).
  
  
  METHODS
  Johannesburg, South Africa.
  
  
  METHODS
  A total of 323 adolescent (15-19 years) homicide victims for the period 2001-9 who had been tested for the presence of alcohol.
  
  
  METHODS
  Data on the victims' BAC level, demographics, weapon or method used, scene, day and time of death were drawn from NIMSS.
  
  
  RESULTS
  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.
