The pattern of life events preceding suicide among the elderly in rural China: a national case-control psychological autopsy study
Abstract Background: There is a lack of evidence of life events prior to suicide and associated with an increasing suicide risk for Chinese rural elderly. The aim of this study was to identify the pattern of life events which precede suicide among the elderly in a Chinese culture context. Methods: A total of 12 counties were randomly selected using two-stage stratified cluster sampling method. 242 suicide cases aged 60 years and older were collected from these counties from February 2014 to September 2015. 242 living controls were matched by age, gender, and location. Data in current study were collected through face-to-face interviews by psychological autopsy method. The 46-item Life Event Scale for the Elderly was used to measure the life events before suicide/interviews. Results: Approximately 99.6% of suicides and 88.4% of controls experienced at least one type of life event. The suicide elderly experienced more long-term life events than recent life events. The top three most frequent life events were being diagnosed with chronic disease, hospitalization, and being diagnosed with terminal illness for suicide elderly. More female suicides experienced the death of spouse, while more males experienced hospitalization, diagnosed with terminal illness and suffered family poverty. Experienced at least one type of life events, had unstable marital status, physical diseases and mental disorders were the probability-changing factors for suicide.Conclusions: Life events were common for the rural elderly, especially long-term life events. The experience of any type of life events is the probability-changing factor for suicide. More attention should be paid to the rural elderly who experienced more long- term life events and experienced health related life events.
