Age‐Specific Characteristics of Serious Suicide Attempters in China

Characteristics of four age groups of patients with medically serious suicide attempts from nine general hospitals in China (N = 617) were compared. There were no significant age‐group differences by residence (rural vs. urban), method of attempt, proportion with prior attempts, or level of family functioning. Attempters <20 years of age were less likely to use alcohol at the time of the attempt. Attempters age 20–44 years had less regular contact with family members but were more likely to make the attempt in the presence of someone else. And attempters ≥ 45 years were more likely to have high suicidal intent, lower quality of life, mood disorders, and substance abuse disorders. These results highlight the need for age‐specific intervention programs for suicide attempters.     

Elevated Suicide Levels Associated with Legalized Gambling

There has been no systematic, large-scale statistical investigation of the link between gambling and suicide, despite the suggestion of such a link from small-scale case studies. This article examines whether gamblers or those associated with them are prone to suicide and whether gaming communities experience atypically high suicide rates. Las Vegas, the premier U.S. gambling setting, displays the highest levels of suicide in the nation, both for residents of Las Vegas and for visitors to that setting. In general, visitors to and residents of major gaming communities experience significantly elevated suicide levels. In Atlantic City, abnormally high suicide levels for visitors and residents appeared only after gambling casinos were opened. The findings do not seem to result merely because gaming settings attract suicidal individuals.     

Adequacy of Official Suicide Statistics for Scientific Research and Public Policy

Many researchers have claimed that the study of suicide and the formation of public policy are not undermined by the misclassification of suicide as other causes of death. We evaluated this claim using a new technique and causes of death not previously considered. We examined computerized California death certificates, 1966-1990. Mortality peaks at symbolic ages are a characteristic feature of suicide. We sought such peaks in (1) causes of death commonly suspected of containing misclassified suicides (e.g., accidental barbiturate poisoning), (2) causes of death not hitherto suspected (e.g., pedestrian deaths), and (3) control groups. The first two categories displayed peaks at symbolic ages, but control groups did not. The size of the peak, indicative of misclassified suicides, varied markedly by race (p < .0001) and sex (p < .0001). Misclassification is evident for all time periods examined, large and small counties, and each race and sex. The maximum misclassification occurs for Blacks (14.92% of officially recorded suicides). We conclude that suicides are misallocated to at least five other causes of death (two of which have not been previously considered in the literature) and are most likely to be underreported for groups with low official suicide rates, that is, Blacks and females. Consequently, Blacks and females are not as protected from suicide as was previously supposed. It may be inadvisable to use official suicide data to test scientific hypotheses about suicide, unless the effects of underreporting are estimated and, if necessary, corrected for.
