Characteristics of young suicides by violent methods in rural China.

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.
