Current knowledge of suicidal behavior in the Western Pacific region is relatively limited when compared to other areas of the world. This area is characterized by a wide diversity of social, economic, and cultural aspects that do not permit any homogenous reading of suicide phenomena. Data from countries of the region included in this article suggest the existence of important differences among nations in terms of gender, age, and methods of suicide, as well role of mental illness. In addition, the Western Pacific region appears to be affected by higher rates of suicide than other areas in the world, with signs of progressive worsening in recent years and worrying predictions for the next two decades. The Suicide Trends in At‐Risk Territories (START) Study, initiated by the World Health Organization Regional Office in Manila, seeks to research the incidence of both fatal and nonfatal suicidal behavior in countries of the region and to implement interventions for suicide attempters. This ambitious project is expected to standardize data collection procedures and improve the knowledge cultural factors in suicide. 相似文献

Intervention research with youths at elevated risk for suicidal behavior and suicide—a vulnerable and high risk population—presents investigators with numerous ethical challenges. This report specifically addresses those challenges involving the informed consent and assent process with parents/guardians and youths. The challenges are delineated in the context of pertinent laws and regulatory requirements, and guidelines are suggested for their practical resolution. These are illustrated with case examples from NIMH‐funded intervention trials. Through the sharing of such methodological information, intervention researchers can support each other in conducting ethical research in a manner that does not unduly compromise scientific rigor. 相似文献

Suicidal ideation during adolescence is quite common. Longitudinal ideation patterns may predict adolescents at greatest risk of progressing to more serious suicidal behaviors. We enumerated suicidal ideation trajectory subgroups and estimated subgroup association with later suicidal plans and attempts using data collected across a 13‐year period from 552 Caucasian adolescents. Three subgroups were found: non‐ideators (no ideation), decreasers (ideation decreased), and increasers (ideation persisted or increased). Probability of planning a suicide was greatest among increasers (females: .54, males: 51, p < .01). Probability of attempting suicide was greatest among male decreasers (.36, p < .01) and female increasers (.25, p < .01). 相似文献

There are worldwide concerns that pro‐suicide web sites may trigger suicidal behaviors among vulnerable individuals. In 2006, A ustralia became the first country to criminalize such sites, sparking heated debate. Concerns were expressed that the law casts the criminal net too widely; inappropriately interferes with the autonomy of those who wish to die; and has jurisdictional limitations, with off‐shore web sites remaining largely immune. Conversely, proponents point out that the law may limit access to domestic pro‐suicide web sites, raise awareness of Internet‐related suicide, mobilize community efforts to combat it, and serve as a powerful expression of societal norms about the promotion of suicidal behavior. 相似文献

The topic of suicide has long been an important socioeconomic issue studied in many countries. Suicides inject an atmosphere of unrest into society, and media attention furthers that social uneasiness. From the viewpoint of economics and management, suicide is a waste of human resource: it decreases the labor force in society and deteriorates human capital. This paper provides a series of analyses of suicide rate based on theoretical reasoning and empirical approaches. Aggregate data from G7 countries are obtained and stacked into panel data for analysis. Data are collected for different age groups. Even though suicide issues have been extensively discussed in the past, newly developed econometric tools are applied to her. Beyond previously recognized relationships between economic factors and suicide rates findings include that unemployment strikes men more than women in terms of psychological pressure: for middle age or older women, unemployment may even be positive for the entire family; and female labor force participation exerts pressure on male counterparts and increases its suicide rate. As a result, a low income family with an unemployed man and an employed woman is at high risk for adult male suicide. 相似文献

The population attributable risk (PAR) of mental disorders compared to indicators of socioeconomic status (SES) for attempted suicide was estimated for Australia. For mental disorders, the highest PAR% for attempted suicide was for anxiety disorders (males 28%; females 36%). For SES, the highest PAR% for attempted suicide in males was for occupation (males 31%; females 16%) and education level (males 19%; females 8%), following adjustment for age and mental disorders. The study results suggest that one third of suicide attempts in both males and females are attributable to anxiety disorders, the same proportion attributable to low educational or occupational status. 相似文献
