Suicide is one of the most common public health problems in the world. Information on 392 completed suicides aged 15-34 years were consecutively collected from 16 counties in three provinces of China. Information on each suicide was obtained from two informants. The results showed ingesting pesticides or other poisons (73.5%) and hanging (10.5%) were the two most common methods of suicide. Suicides happened more in autumn (30.10%) or summer (27.29%), nighttime (68.3%), and at home (73.6%). However, suicides with violent methods were more common in winter and spring and outside of home. Season (autumn or summer), place (at home), and pesticide stored in home were negatively while depression was positively associated with violent methods of suicide. Characteristics of the suicides by violent methods are different from those by nonviolent methods. Investigations into the methods of rural young suicides are necessary for suicide prevention in China.
自杀是世界上最常见的公共卫生问题之一。在中国三个省份的16个县连续收集了392例15至34岁的自杀死亡案例信息。每个自杀案例的信息来自两名 informant。结果显示，服用农药或其他毒物（73.5%）和上吊（10.5%）是两种最常见的自杀方式。自杀事件在秋季（30.10%）或夏季（27.29%）、夜间（68.3%）以及家中（73.6%）更为常见。然而，采用暴力方式的自杀在冬季和春季以及家外更为常见。季节（秋季或夏季）、地点（在家中）以及家中储存农药与采用暴力方式自杀呈负相关，而抑郁与采用暴力方式自杀呈正相关。采用暴力方式自杀的特征与非暴力方式自杀的特征不同。对中国农村青年自杀方式进行调查对于预防自杀很有必要。
