The effect of gender, age, and urban versus rural residence on suicide risk among people with different mental disorders is unknown.
To estimate cohort-specific risk of suicide among people with different types of mental disorders using data from China's National Psychological Autopsy Study.
Logistic regression models estimated adjusted odd ratios (OR) in 895 suicides and 701 injury deaths.
The adjusted risk of suicide for mood disorders was highest (OR = 44.2) followed by that for other mental disorders (OR = 10.7), anxiety disorders (OR = 10.2), psychotic disorders (OR = 7.4), substance use disorders (2.7) and organic mental disorders (OR = 1.2). Risk of suicide among urban residents with any mental disorder was more than double that of rural residents (OR = 15.5 v. 7.6, P = 0.008).
The suicide risk associated with mental illness varies by type of illness and by demographic cohort. Lower risk of suicide among rural residents with mental disorders highlights the importance of non-mental health approaches to the prevention and management of suicidal behaviour in rural areas of low- and middle-income countries.
性别、年龄以及城乡居住环境对不同精神障碍患者自杀风险的影响尚不清楚。
利用中国全国心理解剖研究的数据，估计不同类型精神障碍患者的自杀风险。
使用逻辑回归模型对 895 例自杀和 701 例伤害死亡病例进行了调整后比值比（OR）的估计。
心境障碍的自杀调整风险最高（OR=44.2），其次是其他精神障碍（OR=10.7）、焦虑障碍（OR=10.2）、精神病性障碍（OR=7.4）、物质使用障碍（OR=2.7）和器质性精神障碍（OR=1.2）。任何精神障碍的城市居民自杀风险是农村居民的两倍多（OR=15.5 比 7.6，P=0.008）。
与精神疾病相关的自杀风险因疾病类型和人口队列而异。农村地区精神障碍患者自杀风险较低，突显了在中低收入国家农村地区，采用非心理健康方法预防和管理自杀行为的重要性。
