Effects of restrictive licensing of handguns on homicide and suicide in the District of Columbia

The choice of weapons in firearm suicides in Iowa

This study reports the types of firearms used in firearm suicides in Iowa and tests the hypothesis that the use of handguns, rifles, and shotguns in such suicides reflects the availability of these weapons. The percentage of firearm suicides involving handguns increased from 36.6% in 1980 through 1984 to 43.3% during 1990 and 1991. In both time periods, the use of handguns was more likely than would be expected from their household prevalence. Our data suggest that handguns are disproportionately represented among firearm suicides and that this overrepresentation has increased during the last decade.

Gun ownership as a risk factor for homicide in the home

BACKGROUND

It is unknown whether keeping a firearm in the home confers protection against crime or, instead, increases the risk of violent crime in the home. To study risk factors for homicide in the home, we identified homicides occurring in the homes of victims in three metropolitan counties.

METHODS

After each homicide, we obtained data from the police or medical examiner and interviewed a proxy for the victim. The proxies' answers were compared with those of control subjects who were matched to the victims according to neighborhood, sex, race, and age range. Crude and adjusted odds ratios were calculated with matched-pairs methods.

RESULTS

During the study period, 1860 homicides occurred in the three counties, 444 of them (23.9 percent) in the home of the victim. After excluding 24 cases for various reasons, we interviewed proxy respondents for 93 percent of the victims. Controls were identified for 99 percent of these, yielding 388 matched pairs. As compared with the controls, the victims more often lived alone or rented their residence. Also, case households more commonly contained an illicit-drug user, a person with prior arrests, or someone who had been hit or hurt in a fight in the home. After controlling for these characteristics, we found that keeping a gun in the home was strongly and independently associated with an increased risk of homicide (adjusted odds ratio, 2.7; 95 percent confidence interval, 1.6 to 4.4). Virtually all of this risk involved homicide by a family member or intimate acquaintance.

CONCLUSIONS

The use of illicit drugs and a history of physical fights in the home are important risk factors for homicide in the home. Rather than confer protection, guns kept in the home are associated with an increase in the risk of homicide by a family member or intimate acquaintance.

Pediatric injury prevention

Pediatric injuries are the leading cause of childhood death and disability and are responsible for more childhood deaths than all other diseases combined. The panel summarized the principles of pediatric injury prevention and reviewed the incidence, epidemiology, and prevention of six common pediatric injuries.

Policies to prevent firearm injuries

Firearm-related injuries are a substantial public health problem. A wide array of policies designed to prevent these injuries have been discussed, but few are enacted into legislation. Even fewer have undergone scientific evaluation for their effectiveness. We offer a nosology for categorizing existing and future gun policies. A brief review of the effectiveness of existing gun policies is presented, and an argument is made for redirecting gun policy.

Public health policy for preventing violence

The current epidemic of violence in America threatens not only our physical health but also the integrity of basic social institutions such as the family, the communities in which we live, and our health care system. Public health brings a new vision of how Americans can work together to prevent violence. This new vision places emphasis on preventing violence before it occurs, making science integral to identifying effective policies and programs, and integrating the efforts of diverse scientific disciplines, organizations, and communities. A sustained effort at all levels of society will be required to successfully address this complex and deeply rooted problem.

Suicide in the home in relation to gun ownership

BACKGROUND

It has been suggested that limiting access to firearms could prevent many suicides, but this belief is controversial. To assess the strength of the association between the availability of firearms and suicide, we studied all suicides that took place in the homes of victims in Shelby County, Tennessee, and King County, Washington, over a 32-month period.

METHODS

For each suicide victim (case subject), we obtained data from police or the medical examiner and interviewed a proxy. Their answers were compared with those of control subjects from the same neighborhood, matched with the victim according to sex, race, and age range. Crude and adjusted odds ratios were calculated with matched-pairs methods.

RESULTS

During the study period, 803 suicides occurred in the two counties, 565 of which (70 percent) took place in the home of the victim. Fifty-eight percent (326) of these suicides were committed with a firearm. After excluding 11 case subjects for various reasons, we were able to interview 80 percent (442) of the proxies for the case subjects. Matching controls were identified for 99 percent of these subjects, producing 438 matched pairs. Univariate analyses revealed that the case subjects were more likely than the controls to have lived alone, taken prescribed psychotropic medication, been arrested, abused drugs or alcohol, or not graduated from high school. After we controlled for these characteristics through conditional logistic regression, the presence of one or more guns in the home was found to be associated with an increased risk of suicide (adjusted odds ratio, 4.8; 95 percent confidence interval, 2.7 to 8.5).

CONCLUSIONS

Ready availability of firearms is associated with an increased risk of suicide in the home. Owners of firearms should weigh their reasons for keeping a gun in the home against the possibility that it might someday be used in a suicide.

Women, homicide and alcohol in Cape Town, South Africa

Little is known about the complex circumstances culminating in the homicidal death of a woman. The records of 248 female homicides and suicides admitted to the Salt River State Mortuary between January 1990 and July 1991 were reviewed with specific attention to mode of death and blood alcohol concentration (BAC). Female homicide levels reflected the intensity of violence in specific residential areas. White females were far more likely to die a suicidal, as opposed to homicidal, death (Odds Ratio = 31.94; 95% Confidence Interval, 11.63-90.24). Blunt homicide predominated amongst White females, who were substantially older than the Coloured and African subjects. A BAC greater than 0.1 g per 100 ml was found in 56% of all female homicides studied. An association was found between increasing BAC and sharp homicide amongst women. A high BAC may represent a self-destructive element in a risk-taking situation amongst female homicide victims.
