The charcoal burning suicide epidemics in both Hong Kong and Taiwan have been well documented. However, little is known about the situation in Japan.
To examine the impact of charcoal burning suicide on the overall and other method-specific suicide rates between 1998 and 2007 in Japan.
Using data obtained from the Vital Statistics of Japan, negative binomial regression analyses were performed to investigate the impact of the charcoal burning method.
In males and females aged 15-24 and 25-44 years, the charcoal burning epidemic led to a substantial increase in overall suicides, without a decrease in other methods. In all other age groups, no such trend was observed.
In young Japanese, the charcoal burning method may have appealed to individuals who might not have chosen other highly or relatively lethal methods, and consequently led to an increase in overall suicides.
香港和台湾的烧炭自杀事件已经有详细的记录。然而，日本的情况却鲜为人知。
在 1998 年至 2007 年间，检查烧炭自杀对日本总体自杀率和其他特定自杀方法的影响。
使用从日本人口动态统计数据中获得的数据，采用负二项回归分析来研究烧炭方法的影响。
在 15-24 岁和 25-44 岁的男性和女性中，烧炭自杀的流行导致总体自杀率大幅上升，而其他方法的自杀率没有下降。在所有其他年龄组中，没有观察到这种趋势。
在日本年轻人中，烧炭方法可能吸引了那些可能不会选择其他高或相对致命方法的人，因此导致了总体自杀率的上升。
