Correlating homicide and suicide.

BACKGROUND: The relationship between homicide and suicide has been studied extensively, but with conflicting results. The primary objective of this study was to examine the correlation between homicide and suicide rates in a large cross-sectional sample of UN member states. METHODS: The study used age-standardized data on homicide and suicide for 65 international locales compiled by the World Health Organization. Weighted correlation coefficients between homicide and suicide rates were computed by sex, income level, and geographic region. RESULTS: The overall correlation between homicide and suicide rates was weak and statistically insignificant (rho = -0.08, P = 0.5178). However, when analysed by geographic region the data revealed two distinct patterns: homicide and suicide rates were positively correlated in European countries (rho = 0.89, P < 0.0001), but negatively correlated in the Asia Pacific Region (rho = -0.97, P < 0.0001), and the Americas (rho = -0.62, P < 0.005). CONCLUSIONS: The strength and direction of the relationship between homicide and suicide vary significantly with geographic region. The divergent geographic patterns in the relationship between homicide and suicide might be due to regional differences in social and cultural variables.

Suicide by aircraft: a comparative analysis.

INTRODUCTION: Suicide is the 11 th leading cause of death in the United States. The objective of this study is to document the characteristics of aviation-related suicides and suicide attempts. METHODS: Aviation accidents reported by the National Transportation Safety Board between 1983 and 2003 were screened for cases in which suicide was listed as a probable cause. For each suicide case, two accidents were randomly selected as controls, matched on sex of pilot, type of flight, state, and year of occurrence. Mantel-Haenszel summary Chi-square tests were used to compare cases to controls. Conditional logistic regression modeling was performed to assess the association of pilot and flight characteristics with suicide-related crashes. RESULTS: During the 21-yr study period, 37 pilots committed or attempted suicide by aircraft, with 36 resulting in at least one fatality. All the cases were men and involved general aviation flights. Toxicological test results revealed that 24% of the cases had used alcohol and 14% had used other illicit drugs. Underlying factors included domestic and social problems (46%), legal trouble (40%), and pre-existing psychiatric conditions (38%). Compared with controls, suicide cases involved younger pilots (p < 0.05), were less likely to have another occupant (p < 0.0001), were more destructive to the aircraft (p < 0.0001), and were more likely to have occurred away from the airport (p < 0.0001). CONCLUSION: Aviation crashes caused by suicide differ from unintentional aviation accidents in pilot characteristics, crash circumstances, and outcomes.
