Gender-specific risk for late-life suicide in rural China: a case-control psychological autopsy study

despite unique gender patterns of suicide among older people in rural China, research addressing this issue is scarce. This study aims to clarify the gender-specific risk factors of late-life suicide in rural China.

the study included 242 persons (51% male) aged 60 and above who had committed suicide between June 2014 and September 2015 in the rural areas of three provinces of China. Using 1:1 matched case-control design, 242 living controls matched in age, gender and neighbourhood were randomly selected. Psychological autopsy interviews and psychological assessments were conducted with two informants for each suicide and living control, respectively.

men used alcohol before suicide more than women (12.6 versus 4.7%, P < 0.05). There was no gender difference in suicide method, suicide intent and previous attempts. Univariate analysis showed that married status, mental disorder, depressive symptoms, hopelessness, impulsivity, loneliness, social support, family function and quality of life were associated with suicide in both genders. For men, other risk factors were chronic physical illness and functions of daily living. Variables remaining in the multivariable model for both men and women were depressive symptoms and hopelessness.

depression and hopelessness are the two major risk factors for suicide among both older men and woman in rural China. Suicide prevention programmes focusing on depression and hopelessness in this population are indicated. Also needed are continued efforts to develop and refined gender-specialised strategies to identify high-risk individuals or groups and to enhance targeted support in the rural community.
