Objective: Attempted suicide in later life is under-researched despite its public health significance. In this study, the authors delineated the characteristics of elderly suicide attempters in a representative Chinese sample by comparing them with suicide completers and comparison subjects age 65 years or over who were randomly selected from the community. Methods: There were 224 subjects in this study: 66 suicide attempters, 67 suicide completers, and 91 comparison subjects from the community. Using a casecontrol design and standardized measuring instruments, authors examined the risk and protective factors associated with attempted suicide, making direct comparisons with the community-comparison subjects and suicide completers. Results: A current diagnosis of major depression was associated with a nearly 60-fold increased risk for attempted suicide, and a population attributable risk (PAR) of 67%. Other risk factors included past suicide attempts, poorer function of self-care, arthritis, and specific personality dispositions, particularly low Conscientiousness. Co-residence with children decreased risk. Although the profiles of suicide attempters and completers were similar, they could be distinguished by suicide intent, recent life events (particularly hospitalization), functional competence, religious denomination, and personality characteristics. Conclusions: A high degree of clinical vigilance and multidisciplinary collaboration are required in the management of elderly suicide attempters. The treatment of depression should form a crucial part of the prevention program. Features that distinguish suicide completers from suicide attempters may also carry implications for the secondary prevention of suicide in elderly persons.
