Household firearm storage practices: do responses differ by whether or not individuals ever use firearms?

INTRODUCTION: The prevalence with which firearms are stored loaded or unlocked has been measured in previous surveys. Our purpose was to compare household firearm storage practices reported by firearm users and nonusers. METHODS: We analyzed telephone survey data from the 1992 and 1993 Oregon Behavioral Risk Factor Surveillance System on 2454 randomly selected adults in households with firearms. We compared reported firearm storage practices among persons who ever used firearms with persons who had never used firearms by demographics and type of firearm. RESULTS: Nonusers of firearms were much less likely than firearm users to report that household firearms were always or sometimes stored loaded [odds ratio (OR) = 0.45, 95% confidence interval (CI):0.36-0.54] or stored loaded and unlocked (OR = 0.46, 95% CI: 0.36-0.57). Except for persons aged 18 to 34 years and persons in handgun-only households, differences in reported firearm storage practices between nonusers and users varied little by demographic characteristics or by type of firearm. Nonusers of household firearms may be unaware that firearms are stored loaded or stored loaded and unlocked in their homes. CONCLUSIONS: Surveys that do not consider firearm use status may underestimate household exposure to loaded firearms or to loaded and unlocked firearms.

Preventing youth violence: what works?

Between 1985 and 1992, serious youth violence in the United States surged to unprecedented levels. The growing use of firearms to settle disputes has contributed to this phenomenon. Youth are most often victimized by one of their peers. In response to this problem, a wide variety of programs have been implemented in an attempt to prevent youth violence or reduce its severity. Few have been adequately evaluated. In general, interventions applied between the prenatal period and age 6 appear to be more effective than interventions initiated in later childhood or adolescence. Community-based programs that target certain high-risk behaviors may be beneficial as well. A sustained commitment to evaluation research is needed to identify the most effective approaches to youth violence prevention.

Population estimates of household firearm storage practices and firearm carrying in Oregon.

OBJECTIVES: To examine statewide data on exposure of adults and children to loaded and unlocked household firearms, and to estimate the prevalence of firearm carrying among adults in Oregon. DESIGN: Analyses of 1992 and 1993 telephone survey data from 6202 adults aged 18 years and older using the Oregon Behavioral Risk Factor Surveillance System. MAIN OUTCOME MEASURES: Number of adults and children exposed to household firearms always or sometimes stored loaded and unlocked. Adjusted odds ratios (ORs) for exposure to loaded and unlocked firearms and firearm carrying among adults by demographic and alcohol use patterns. RESULTS: Ten percent of adults (197 400 persons) lived in households with firearms that were always or sometimes stored loaded and unlocked. An estimated 6.2% of households with children had firearms that were loaded and unlocked, and about 40 000 children lived in these households. Overall, 4.4% of adults carried loaded firearms in the past month. Rural residence, male sex, and less than a college education were associated with living in a household with loaded and unlocked firearms and with firearm carrying. Drinking 5 or more alcoholic beverages on 1 or more occasions in the past month (OR, 1.7; 95% confidence interval, 1.3-2.3) or drinking 60 or more alcoholic beverages in the past month (OR, 1.8; 95% confidence interval, 1.2-2.7) were independently associated with living in households with loaded and unlocked firearms. CONCLUSIONS: Many adults and children are exposed to unsafely stored firearms in Oregon, and many adults carry loaded firearms. Improved public health surveillance of firearm storage and firearm carrying using standardized questions and definitions is needed at the national, state, and local levels.

Suicide clusters: an examination of age-specific effects.

The age specificity of time-space clusters of suicide was examined using National Center for Health Statistics data for 1978-84. Significant clustering of suicide occurred primarily among teenagers and young adults, with minimal effect beyond 24 years of age. Clustering was two to four times more common among adolescents and young adults than among other age groups.

An application of the empirical Bayes approach to directly adjusted rates: a note on suicide mapping in California.

A simple, reliable, and comparable measure for suicide mapping and other health problems is needed. Because standardized mortality ratios (SMRs) may not indicate the relative meaning of their magnitudes when compared with one another, and statistical significance levels of tests for SMRs overlook the areas that have small populations, neither of these approaches provides a satisfactory index. The results using directly adjusted rates can be ordered directly according to their magnitudes. However, because of the lack of reliable estimates of local age-specific rates, the usefulness of directly adjusted rates in mapping suicide is also limited. To extend the usefulness of directly adjusted rates, an empirical Bayes approach whereby information from other areas is borrowed to improve the precision of the estimates of local age-specific rates in calculating directly adjusted rates--especially in the areas with small population sizes--is proposed. When an empirical Bayes approach was applied to the 1983 suicide data for California counties, a more reasonable conclusion than could be obtained by using directly adjusted rates was reached.

Nonfatal physical violence, United States, 1994.

OBJECTIVES: Most surveillance and research efforts focus on severe violence, especially on homicides. Because less extreme forms of violence may be precursors to more extreme forms, the authors analyzed data from a national survey to describe the extent of nonfatal physical violence in the US. METHODS: The authors generated weighted national estimates from responses to a random-digit-dialed telephone survey. Respondents were asked if they had been "hit, slapped, pushed, or kicked by another person or hit with an object or weapon" in the preceding 12 months. Respondents were also asked how many times such incidents had occurred and, for the last such episode, their relationship with the perpetrator, whether they had been injured, and, if so, whether they had sought medical treatment. RESULTS: The authors estimate that approximately 15 million people, or 8% of the US adult population, experienced nonfatal physical violence, as defined for this study, during a 12-month period. Male gender, the 18-24-year-old age group, never having been married, being out of work or a student, and heavy drinking were associated with a higher likelihood of being assaulted. An estimated 75% of assaults were by a known person and 26% by a stranger. Women were more likely than men to be assaulted by current or former intimate partners; men were more likely than women to be assaulted by strangers. An estimated 18% of incidents resulted in injuries, and an estimated 7% required medical attention. CONCLUSIONS: Nonfatal physical violence is fairly common in the US and may lead to more than one million medical encounters each year.
