The suicide rate in England and Wales has increased annually in the period 1975 to 1980. The increase has occurred in both sexes, but has been greater for males. There has been a decrease in suicide by poisoning with solid or liquid substances (including overdoses) and a marked increase in poisoning by vehicle exhaust gas. The rate of hanging, strangulation and suffocation has also increased substantially: taken together (ICD E953) these now form the most common method of suicide in males. Statistics for 'undetermined' and 'accidental' death have been examined, and indicate that the increase in the official suicide rate represents a real increase in suicides during this period.
1975年至1980年期间，英格兰和威尔士的自杀率逐年上升。男女自杀率均有所上升，但男性上升幅度更大。固体或液体物质中毒（包括过量服药）导致的自杀有所减少，而汽车尾气中毒导致的自杀显著增加。上吊、勒死和窒息的发生率也大幅上升：综合起来（国际疾病分类E953），这些现在已成为男性最常见的自杀方式。对“死因不明”和“意外”死亡的统计数据进行了审查，结果表明，官方自杀率的上升表明这一时期自杀事件确实有所增加。
