Understanding the unique characteristics of suicide in China: national psychological autopsy study.

OBJECTIVE: To compare the characteristics of suicides in the four main demographic groups: urban males, urban females, rural males and rural females in order to help clarify the demographic pattern of suicides in China. METHODS: A detailed psychological autopsy survey instrument was independently administered to 895 suicide victims in family members and close associates from 23 geographically representative locations from around the country. RESULTS: Pesticide ingestion accounted for 58% (519) of all suicides and 61% (318/519) of deaths were due to unsuccessful medical resuscitation. A substantial proportion (37%) of suicide victims did not have a mental illness. Among the 563 victims with mental illness, only 13% (76/563) received psychiatric treatment. Compared to other demographic groups, young rural females who died from suicide had the highest rate of pesticide ingestion (79%), the lowest prevalence of mental illness (39%), and the highest acute stress from precipitating life events just prior to the suicide. CONCLUSION: Many suicides in China are impulsive acts of deliberate self-harm following acute interpersonal crises. Prevention of suicides in China must focus on improving awareness of psychological problems, improving mental health services, providing alternative social support networks for managing acute interpersonal conflicts, limiting access to pesticides, and improving the resuscitation skills of primary care providers.
