Objective： To explore the status and related factors of suicidal behavior in rural elderly. Methods： Totally 1040 rural community residents aged 60 years or more were selected by stratified cluster random sampling method and investigated with the self-designed demographic characteristics inventory, self-made suicidal behavior inventory, Patient Health Questionnaire-9（PHQ-9） and Life Events Scale for the Elderly （LESE）. Results： In this sample, the prevalence of suicidal ideation, plans, preparation and attempts were 21.5%, 5. 5%, 2. 2% and 0. 8% during the preceding 12 months. Unconditional logistic regression showed that low self-evaluated health status （OR = 1.43）, more stimulations from negative life events （OR = 3.18） and depression screening positive （OR = 20. 01） were risk factors of suicidal behavior. Conclusion： It suggests that the prevalence of suicidal behavior among rural elderly in Hengyang is high. Poor self-evaluated health status, more stimulations from negative life events and depression screening positive may be the independent risk factors of suicidal behavior.
