This study reports changes of suicide rate in Australia and in England and Wales in the twenty years up to 1976. Rates in both places reached a peak in 1963, related to increases in poisoning as a means of suicide. Decreases since then can be attributed partly to reduced likelihood of death after inhalation of domestic gas or after ingestion of poisons. There has been an increase in suicide deaths among younger people, but a decrease among older age groups. The two countries have patterns of suicide which are similar in many respects, the most striking difference being the frequency with which firearms are used by male suicides in Australia. There is good reason to believe that variation in availability of a means of suicide is the factor which has most effect on rates of suicide, though cultural attitude towards each method also is an important determinant of how much it will be used for suicide.
本研究报告了截至1976年的二十年里澳大利亚以及英格兰和威尔士自杀率的变化情况。两地的自杀率在1963年达到峰值,这与作为自杀手段的中毒事件增多有关。自那时起自杀率下降,部分原因是吸入家用煤气或摄入毒物后死亡可能性降低。年轻人自杀死亡人数有所增加,但老年群体自杀死亡人数则有所下降。这两个国家的自杀模式在许多方面相似,最显著的差异在于澳大利亚男性自杀者使用枪支的频率。有充分理由相信,自杀手段可得性的差异是对自杀率影响最大的因素,不过对于每种自杀方法的文化态度也是决定其被用于自杀程度的重要因素。
