Rural population survey of behavioral and demographic risk factors for loaded firearms.

OBJECTIVES: In the United States, firearm deaths are almost as frequent as motor vehicle deaths. Firearm unintentional and suicide death rates are raised in rural areas. This study examines firearm prevalence and storage practices in three different types of rural households. METHODS: Adults from a stratified random sample of 983 households in a rural Iowa county were interviewed. The chi2 test of independence was used to assess association between loaded, unlocked firearms and seven behavioral and demographic risk factors. RESULTS: Nearly 67% of respondents reported firearms in their households. Nearly 7% of households had a loaded, unlocked gun. Prevalence of firearms at home was higher while prevalence of loaded, unlocked guns was lower than reported in other surveys. Prevalence of loaded, unlocked guns in farm households, 10.5%, was about twice the level in town households, 5.5% (chi2 test, p=0.033). Having taken a gun safety course was associated with more than double the prevalence of a loaded, unlocked gun, 13.5% v 5.1% (chi2 test, p=0.001). The prevalence of loaded, unlocked guns in households with a handgun, 19.3%, was four and one half times higher than in households with a long gun only, 4.2% (chi2 test, p=0.001). Households with someone with a lifetime prevalence of alcohol abuse or dependence were about twice as likely as other households, 13.0% v 6.6% (chi2 test, p=0.004), to report having loaded, unlocked firearms. CONCLUSIONS: Anyone interested in promoting safe storage of firearms in rural homes should consider these observations.

Firearm-related injuries and deaths among children and adolescents in Cape Town--1992-1996.

OBJECTIVE: To determine the epidemiological profile of firearm-related injuries among children and adolescents in Cape Town during recent years in order to further understand the epidemic of firearm violence as a public health problem in South Africa. DESIGN: A retrospective study was conducted of hospital, medico-legal laboratory (mortuary) and police data. SETTING: Metropolitan Cape Town, 1 January 1992-31 December 1996. STUDY POPULATION: All children and adolescents (under 19 years of age) with firearm injuries living in the Cape Town metropole during the study period. RESULTS: During the study period at least 1,736 children and adolescents were victims of firearm-related incidents; of these, 322 died (19%). The incidence of firearm injuries among this group almost tripled from 20.2/100,000 in 1992 to 58.1/100,000 in 1996. The firearm mortality rate also almost tripled during the period under review from 3.8/100,000 in 1992 to 10.3/100,000 in 1996. Approximately 60% of victims were coloured males, with 86% between 13 and 18 years of age. Twenty-one per cent of all victims aged over 12 years who died were intoxicated. Other characteristics of the victims and the circumstances surrounding the incidents are presented. CONCLUSIONS: These findings demonstrate the escalating epidemic of firearm-related injuries and deaths among children and adolescents in Cape Town. In addition, the study indicates the need for an integrated injury and death reporting system. Further research is needed to understand firearm-related injuries among children and adolescents in South Africa, and to develop policies and programmes for prevention that are effective in this setting.

Firearm availability and female homicide victimization rates among 25 populous high-income countries.

OBJECTIVE: to determine the association between firearm availability and female homicide victimization among high-income countries. METHODS: Data were assembled for the most recent available year (1994-1999) from the official reports of the ministries of health for those countries that had more than 2 million inhabitants and were dassified as high income by the World Bank. Twenty-five nations provided sufficient information for the analysis. Rates of female victimization from homicide, firearm homicide, and nonfirearm homicide were compared with a validated proxy for household firearm ownership (the percentage of total national suicides that are committed with firearms). Possible confounding variables included in the analysis were the percentage of the population living in urban areas and income inequality. RESULTS: The United States is an outlier. It had the highest level of household firearm ownership and the highest female homicide rate. The United States accounted for 32% of the female population in these high-income countries, but for 70% of all female homicides and 84% of all female firearm homicides. Female homicide victimization rates were significantly associated with firearm availability largely because of the United States. CONCLUSION: Among high-income countries, where firearms are more available, more women are homicide victims. Women in the United States are at higher risk of homicide victimization than are women in any other high-income country.

Managing suicide risk in late life: access to firearms as a public health risk.

OBJECTIVE: The authors assessed the prevalence of gun availability for elderly patients to determine whether gun availability is related to the presence of suicidal or depressive symptoms. METHODS: This is a cross-sectional epidemiologic survey of firearm availability and safety practices. A random sample of older adults with a scheduled primary-care clinic appointment was selected and screened with the General Health Questionnaire and questions about suicidality and alcohol use. Participants were also asked about the availability of firearms in their home and about safe gun practices. RESULTS: Of 1,023 patients screened, 285 (27.9%) reported having some type of firearm in the home, and 202 (19.7%) reported having a handgun in the home. Patients with suicidal ideation or high levels of depression or psychological distress were not significantly more or less likely to have a gun in the home than those without these emotional stressors. The strongest predictors of firearm availability were being male and being married. CONCLUSIONS: These preliminary data suggest that a significant proportion of elderly people have firearms available to them in their homes. Those patients with emotional distress did not differ from those without distress with respect to having firearms available to them. These data strongly suggest the need for screening for firearm availability and education about the safe storage of firearms as a potential means of prevention of suicide among elderly patients suffering from emotional distress or suicidal ideation.

Firearms in New Mexico.

To determine the prevalence of firearm ownership and storage practices in New Mexico, we did a random-digit-dialing survey of New Mexico residents in October 1991. Of 200 households surveyed, 79 (40%) had 1 or more firearms in the home. Rural households were more likely than urban households to have firearms (44% versus 30%), and households with annual incomes of greater than $25,000 were more likely to have a firearm than households with incomes of $25,000 or less (41% versus 33%). Household firearm ownership did not vary with the presence of young (< 15 years old) children (38% with children versus 41% without). Handguns were generally owned for self-protection, and rifles were owned for hunting. Of households with firearms, 24% stored them unsafely (unlocked and loaded or unloaded but with ammunition nearby), including 21% of households with young children. Of the households with handguns only, 40% stored these firearms unsafely compared with 13% of those with rifles only. The prevalence of gun ownership in New Mexico is similar to that reported in national surveys; handguns are stored less safely than rifles; and the presence of young children in the home does not appear to improve firearm storage safety.

State gun safe storage laws and child mortality due to firearms.

CONTEXT: Since 1989, several states have passed laws that make gun owners criminally liable if someone is injured because a child gains unsupervised access to a gun. These laws are controversial, and their effect on firearm-related injuries is unknown. OBJECTIVE: To determine if state laws that require safe storage of firearms are associated with a reduction in child mortality due to firearms. DESIGN: An ecological study of firearm mortality from 1979 through 1994. SETTING: All 50 states and the District of Columbia. PARTICIPANTS: All children younger than 15 years. MAIN OUTCOME MEASURES: Unintentional deaths, suicides, and homicides due to firearms. RESULTS: Laws that make gun owners responsible for storing firearms in a manner that makes them inaccessible to children were in effect for at least 1 year in 12 states from 1990 through 1994. Among children younger than 15 years, unintentional shooting deaths were reduced by 23% (95% confidence interval, 6%-37%) during the years covered by these laws. This estimate was based on within-state comparisons adjusted for national trends in unintentional firearm-related mortality. Gun-related homicide and suicide showed modest declines, but these were not statistically significant. CONCLUSIONS: State safe storage laws intended to make firearms less accessible to children appear to prevent unintentional shooting deaths among children younger than 15 years.

Lethality of firearm-related injuries in the United States population.

STUDY OBJECTIVE: To characterize differences in the lethality of firearm-related injuries in selected demographic subgroups using national representative data on fatal and nonfatal firearm-related injuries. We also characterize the lethality of firearm-related injuries by intent of injury and anatomic location of the gunshot wound. METHODS: We analyzed case-fatality rates (CFRs) of firearm-related injuries in the United States by using death data from the National Vital Statistics System and data on nonfatal injuries treated in US hospital emergency departments from the National Electronic Injury Surveillance System. National estimates of crude and age-adjusted CFRs are presented by sex, race/ethnicity, age, intent, and primary body part affected. RESULTS: Each year during the study period (July 1992 through December 1995), an estimated 132,687 persons sustained gunshot wounds that resulted in death or treatment in an ED. The overall age-adjusted CFR among persons who sustained firearm-related injuries was 31.7% (95% confidence interval [CI] 27.7 to 35.6). The age-adjusted CFR for persons who were alive when they arrived for treatment in an ED (11. 3%; 95% CI 9.4 to 13.2) was about one third as large as the overall CFR. The age-adjusted CFR varied by sex, race/ethnicity, and age, but these differences depended on intent of injury. For assaultive injuries, the age-adjusted CFR was 1.4 times higher for females (28. 7%) than males (20.6%). For intentionally self-inflicted injuries, the age-adjusted CFR was 1.1 higher for males (77.7%) than females (69.1%). For assaults, the age-adjusted CFR was 1.5 times higher for whites (29.5%) than blacks (19.2%). For assaultive and intentionally self-inflicted injuries among persons 15 years and older, the age-specific CFR increased with age. Persons shot in the head (age-adjusted CFR, 61.0%) were 3.3 times as likely to die as those shot in other body parts (age-adjusted CFR, 18.7%). CONCLUSION: The lethality of firearm-related injuries was influenced strongly by the intent of injury and body part affected. The high lethality of firearm-related injuries relative to other major causes of injury emphasizes the need to continue prevention efforts and efforts to improve access to care and treatment (including emergency medical and acute care services) to reduce the number and increase survivability of firearm-related injuries.

A time-series analysis of trends in firearm-related homicide and suicide.

In order to determine whether firearm use was an increasing component of the general pattern of homicide in Cape Town, South Africa, hidden Markov time-series models were used to examine a week-by-week count of firearm homicides, non-firearm homicides, firearm suicides and non-firearm suicides for the 6-year period from 1986 to 1991. Of several models fitted to the proportion of homicides that involved firearms, the one which incorporated a discrete upward shift in the middle of 1991 was the most successful. There was no evidence of a similar upward shift in the proportion of the suicides that involved firearms. The sharp increase in 1991 in the probability that a homicide involved the use of a firearm is consistent with a reported upsurge in violence related to the so-called 'taxi wars'. Hidden Markov models, as a general methodology for the analysis of discrete-valued time series, may be a useful and flexible means of identifying time trends or points of transition related to events or interventions in a wide range of public health contexts.

Incidence rates of firearm injuries in Galveston, Texas, 1979-1981.

Firearm injury mortality rates have been characterized in various settings, but little is known of the total magnitude of firearm injury, including morbidity. The authors determined population-based incidence rates of firearm injury among residents of Galveston, Texas, from 1979-1981 by using police, emergency department, hospital, emergency medical services, medical examiner, and vital records to identify 239 firearm injury cases. Vital records, medical examiner, and police records each identified more than 95% of the fatalities, but police records (sensitivity = 98%) were better than emergency department or hospital records (sensitivity = 82% and 28%, respectively) for identifying all nonfatal cases. The annual age-adjusted incidence rate of firearm injury was 128 per 100,000 persons. Black males, with the highest firearm injury rate (459 per 100,000 persons), were injured at 46 times the rate of white females (10 per 100,000 persons). The overall case fatality rate was 30%, including 25% of the assaults/homicides, 81% of the parasuicides/suicides, and 0% of the unintentional injuries. On the basis of the case fatality rates, an estimated 140,000 firearm injuries occur in the United States annually. The case fatality rate for penetrating head injuries was 80% versus 48% for chest injuries and 6% for all other parts of the body. The results are discussed with respect to policy recommendations for reducing firearm injuries.

Nonintracranial fatal firearm injuries in children: implications for treatment.

BACKGROUND: Understanding the injury characteristics of nonintracranial fatal (NIF) gunshot wounds in children treated in a statewide trauma system will help guide effective treatment strategies. METHODS: This study was a retrospective analysis of children fatally injured with firearms. The review included demographic information, firearm injury characteristics, and outcome. The setting included trauma centers participating in a statewide trauma registry. Patients were all children (age < 18 years) treated in trauma centers for NIF gunshot wounds from January 1988 through December 2000. The main outcome measures were characteristics of fatal firearm injuries in children. RESULTS: Over the 13-year period, there were 1,954 children with firearm injuries including 368 (18.8%) children with fatal wounds. Of the fatally wounded children, 177 (48.1%) had no intracranial injury. The NIF injury population was 90.4% male, with a mean age of 14.9 years (range, <1-17 years) and an Injury Severity Score of 38.2 (range, 9-75). Over 95% of deaths in this group occurred within 24 hours of admission. Although injuries to the thorax were most common (78.5%), 48.6% of the NIF cohort had injuries to multiple body regions, including 31% with injuries in both the abdomen and thorax. Compared with all children wounded by firearms, NIF firearm injury patients had, on average, more body regions injured (1.6 vs. 1.1, p < 0.001) and a greater total number of injuries (6.0 vs. 3.5, p < 0.001). Patients with an NIF injury were more likely to suffer a major vascular injury (54.8% vs. 13.8%, p < 0.001), lung injury (56.5% vs. 12.9%, p < 0.001), or cardiac injury (44.6% vs. 4.6%, p < 0.001) than all children with a firearm injury. CONCLUSION: Most children who arrive at trauma centers alive and subsequently die from NIF firearm injuries do so rapidly from major vascular and thoracic injury. Almost half of these children have injuries to multiple body regions, further complicating management. Innovative, aggressive treatment approaches should be sought to improve survival in this extremely injured cohort of children.

Trends in hanging and firearm suicide rates in Australia: substitution of method?

This study examined the increase in the rate of suicide by hanging and an apparently simultaneous decrease in the rate of suicide by firearm as hypothetical evidence that Australian males have substituted one method of suicide for another. Trends in hanging and firearm suicide rates were examined from 1975 to 1998 for all Australian males and from 1971 to 1998 for a subset of Australian male youth, as well as a group of Australian males aged over 64 years at the time of their death. When the firearm suicide rate for Australian males declined the hanging rate increased simultaneously, with no statistical difference in the rate of change of the two methods. A similar pattern of simultaneous divergence in hanging and firearm suicide rates of a 15- to 24-year-old subgroup occurred at a not dissimilar rate over a longer time period. Rates of suicide by hanging were found to have begun increasing prior to the decline in firearm suicide. The declining rate of firearm suicide in the 15- to 24-year-old subgroup coincided with an increase in the overall suicide rate. Relationships between trends in hanging and firearm suicide differed between states and between urban and non-urban areas within Queensland, with the firearm suicide rate falling more rapidly in urban areas, especially following the introductions of restrictions to weapon purchases. Individual suicide method choice may be related to independent changes in the social acceptability of each method, as well as to an increasing prevalence of suicide in younger males, who are more likely to use the hanging method. The functioning and effect of social acceptability remains unclear, however. Intervention and prevention strategies should focus on challenging the social acceptability of hanging, especially among males aged 15 to 24 years.

Comparative study on effects of burn-blast combined injury and burn-firearm combined injury complicated with seawater immersion on vascular endothelial cells.

OBJECTIVE: To comparatively study the effects and mechanisms of burn-blast combined injury and burn-firearm combined injury complicated with seawater immersion on vascular endothelial cells. METHODS: A total of 40 healthy adult hybrid dogs of both sexes, weighing 12-15 kg, were used in this study. Randomly-selected 20 dogs were established as models of burn-blast combined injury (the burn-blast injury group) and the other 20 dogs as models of burn-firearm combined injury (the burn-firearm injury group). Then the wounds of all the dogs were immediately immersed in seawater for 4 hours, and then they were taken out from the seawater. Blood samples were withdrawn from the central vein of the dogs before injury, and at 4, 7, 10, 20, and 28 hours after injury to measure the circulating endothelial cells and the von Willebrand factor. RESULTS: Circulating endothelial cells increased significantly at 4 hours after injury in all the dogs. But they reached peak at 7 hours after injury in the burn-blast injury group and at 28 hours after injury in the burn-firearm injury group. The changes of circulating endothelial cells in the burn-blast injury group were significantly different from those in the burn-firearm injury group at 4, 7, 20, and 28 hours after injury (P < 0.01). The von Willebrand factor reached peak at 4 hours after injury in the burn-blast injury group and at 28 hours in the burn-firearm injury group. The changes of von Willebrand factor in the burn-blast injury group were significantly different from those in the burn-firearm injury group at 4, 20, and 28 hours after injury (P < 0.01). CONCLUSIONS: In burn-blast injury combined with seawater immersion, the vascular endothelial cells changed most significantly at 4 hours or 7 hours after injury, while burn-firearm injury combined with seawater immersion have the same at 20 hours or 28 hours after injury.

Pediatric firearm injuries, Kansas City, 1992: a population-based study.

OBJECTIVE: To determine the morbidity, mortality, and epidemiologic features of pediatric powder-firearm injuries in a defined urban population. DESIGN AND SETTING: A population-based, descriptive epidemiologic study was conducted of firearm injuries to children in a mid-size urban community (total population: 435,178) in 1992. The population was 56% white and 39% black. Data from prehospital care providers, all city and adjacent community hospitals, and medical examiner and police records were searched for cases of firearm injury. The 1990 United States census provided denominator data. CASE DEFINITION: Subjects were all 0- to 16-year-old residents of Kansas City, Missouri who sought medical treatment at a hospital for a powder-firearm injury or who presented to the medical examiner with a fatal firearm injury in calendar year 1992. RESULTS: Seventy-two children met the case definition, for an incidence of 70 per 100,000 persons per year. There were 12 (16.7%) fatalities, for a mortality rate of 11.7 per 100,000 persons per year. Almost 10% of the patients sustained permanent disability. Mean and median ages of the patients were 14.9 years and 15.8 years, respectively; 79% were male and 82% were black. The majority of the children (63%) lived in census tracts with a high proportion of families in poverty. Black males had the highest rates of firearm injury, with a 1-year incidence of 233 per 100,000 persons per year. At younger than 12 years, the rates were equal among the races; however, for those 12 years and older, black adolescents had 13 times the risk of white adolescents (541 compared to 42 per 100,000 persons per year). The majority (71%) of injuries were due to assaults, with drive-by shootings the most frequent circumstance. The majority of unintentional injuries occurred to adolescents as the result of an unplanned discharge of a handgun as it was being placed in or removed from concealment. Among the patients, 39% were admitted to the hospital and 26% required surgery. CONCLUSIONS: 1) Black male adolescents had the highest risk of firearm injury or fatality. 2) The majority of victims lived in census tracts characterized by poverty. 3) injuries were alarmingly severe. 4) Interpersonal violence was the leading contributor to fatal and nonfatal injuries. 5) Unintentional injuries characteristically occurred during the process of weapon concealment. 6) The leading contributor to injury and death was the interaction of adolescents and guns, particularly handguns. The main implication for firearm-injury prevention in this population is the limiting of access to guns by adolescents. In addition, measures aimed at preventing violent behavior, such as education in nonviolent methods of conflict resolution, should be explored.

Parental misperceptions about children and firearms.

OBJECTIVE: To assess the accuracy of parental predictions about their children's self-reported behavior around household guns. DESIGN: Survey. SETTING: Family practice clinic in rural Alabama. PARTICIPANTS: Convenience sample of parents and their children aged 5 to 14 years. INTERVENTION: Questionnaires about firearms administered separately to children and their parents. MAIN OUTCOME MEASURES: Rates of concordance and discordance between parents and their children living in homes with guns about whether the children knew the storage location of household firearms and had ever handled firearms in the home. RESULTS: Of 420 parent-child dyads, 314 agreed to participate; 201 of the 314 homes contained guns. Children younger than 10 years were as likely as older children to report knowing the storage location (73% vs 79%, respectively) and to report having handled a household gun (36% vs 36%, respectively). Thirty-nine percent of parents who reported that their children did not know the storage location of household guns and 22% of parents who reported that their children had never handled a household gun were contradicted by their children's reports. Such discordance between parent and child reports was unrelated to whether parents stored their firearms locked away or had ever discussed firearm safety with their children. CONCLUSIONS: Many parents who were living in homes with firearms and who reported that their children had never handled firearms in their homes were contradicted by their children's self-reports. Parents who locked their guns away and discussed gun safety with their children were as likely to be contradicted as parents who did not take such safety measures.

Pediatric firearm-related fatalities. Not just an urban problem.

OBJECTIVE: To examine medical and demographic factors associated with the firearm-related deaths among children in Kentucky. DESIGN: Retrospective review and multiple regression analysis. DATA SOURCE: All firearm-related deaths among children younger than 20 years reported to the Kentucky Office of Vital Statistics, Frankfort, from 1988 to 1993. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: All 320 pediatric firearm-related deaths that occurred in Kentucky from 1988 to 1993 were analyzed. Death rates were calculated for each county in the state. While the overall death rate from firearms was not significantly different between African-American and white children (relative risk [RR], 1.39; 95% confidence interval [CI], 0.98-1.98), the pattern of the types of events was markedly different. African American children were much more likely to have been involved in a homicide; suicides were more frequent in white children. Multiple Poisson regression analysis, controlling for age, race, and gender, identified only 1 variable that was significantly associated with deaths due to firearms. Children in rural Kentucky were at significantly more risk for a firearm-related death than children in urban areas (RR, 1.26; 95% CI, 1.01-1.62) even after controlling for medical system variables (availability of a hospital with 24-hour emergency services, availability of prehospital advanced life support, and availability of 911 service). CONCLUSIONS: Children in rural areas of Kentucky are at an increased risk for firearm-related mortality. Prevention and intervention programs that focus only on urban areas may not produce optimum results in the Kentucky setting. Further research is needed to determine factors that are important in rural areas so that interventions specific to them can be planned.

Training in firearm safety counseling in pediatric residency programs.

OBJECTIVE: To examine the status of formal training in pediatric residency programs with regard to firearm safety counseling. DESIGN: Survey. SETTING: Pediatric residency programs of the coterminous United States (N = 209). PATIENTS OR OTHER PARTICIPANTS: The population of pediatric residency program directors. INTERVENTIONS: None. MAIN OUTCOME MEASURES: A national baseline assessment of the proportion of pediatric residency programs with formal training on firearm safety counseling. In addition, the content taught, methods of provision, barriers to offering such training, and resources that could increase the number of programs offering such training. RESULTS: The response rate of the residency directors was 77%. One third of the residency programs offered formal firearm safety counseling training. Sixty-five percent of the respondents strongly agreed that it is the pediatrician's responsibility to counsel on this topic. Few residency directors (19%) perceived that firearm safety counseling would be effective in reducing the number of accidental firearm injuries or deaths. The 3 resources most frequently identified that, if available, would increase the amount of time residencies would spend on training were video training programs (64%), patient education materials (62%), and a curriculum guide (55%). CONCLUSIONS: Pediatricians have a vested interest in preventing childhood firearm violence. Yet, fewer than half of the residency directors believed that firearm issues be given high priority in residency programs. The barriers to providing such training (eg, no trained personnel and lack of educational resources) should not be major impediments to resolving this health problem.

Firearm ownership and storage practices, U.S. households, 1992-2002. A systematic review.

BACKGROUND: Because the presence and improper storage of household firearms are risk factors for injury, it is important to understand the prevalence of ownership and storage practices within households to help guide intervention development. This systematic review of published articles (1992 to 2002) provides prevalence estimates of firearm ownership and storage practices in U.S. households. METHODS: A search of bibliographic databases (MedLine, CINAHL, PsycInfo, Sociological Abstracts) was completed in January 2003. RESULTS: Although all were cross-sectional, the 42 articles included in this review varied in type; there were seven national and five state prevalence studies, as well as studies using clinic-based convenience samples (n =14) and samples of professionals (n =10). Published studies indicate that firearms are present in about one third of U.S. households. Handguns in particular are present in more than half of U.S. households with firearms, or about 19% of all U.S. households. The prevalence of firearms and handguns in households with young people was similar to the prevalence overall. Firearm ownership was highest in the South. CONCLUSIONS: Although the methodologic rigor of published articles varies substantially, the literature clearly establishes that firearms are common in U.S. households, even in the homes of medical professionals and those with children.

Social trust, firearm prevalence, and homicide.

PURPOSE: Past research suggests that Americans arm themselves when they do not trust one another. We reexamine the relationship between social trust and firearm prevalence with improved data and methods. We also control for conditions, including area homicide rates, that other research showed to be related to both social trust and firearm prevalence. METHODS: We use structural equation models to assess reciprocal effects of social trust, firearm prevalence, and homicide rates for a nationally representative sample of counties and county clusters (n = 99). RESULTS: We found no direct relationship between social trust and firearm prevalence. Social trust is related to firearm prevalence indirectly through its influence on homicide rates. Areas with low levels of social trust have high homicide rates, which, in turn, increase firearm prevalence. CONCLUSIONS: Americans arm themselves in response to high levels of firearm violence. Because greater social trust is related to lower homicide rates, public health researchers should be concerned with the community conditions that promote social trust.
