Multicenter Study Comparative Study
An ecologic study of protective equipment and injury in two contact sports.
Contact sports have high rates of injury. Protective equipment regulations are widely used as an intervention to reduce injury risk. The purpose of this study was to investigate the injury prevention effect of regulations governing protective equipment in two full-body contact sports. ⋯ The observed differences are consistent with the hypothesis that regulations mandating protective equipment reduce the incidence of injury, although important potential biases in exposure assessment cannot be excluded. Further research is needed into head protection for rugby players.

Previous studies analysing Karachi ambulance data from 1993 to 1995 identified neighbourhoods in Karachi disproportionately affected by homicide. As a step toward developing intervention programmes to curb violence, we conducted a study to identify risk factors for becoming a homicide victim in a high violence area of Karachi. ⋯ Homicide in Orangi was political. Efforts to improve trust between ethnic groups and to build legitimacy for non-violent forms of conflict resolution are important steps to limit future violence.
