Attempted suicide in elderly Chinese persons - A multi-group, controlled study

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 case-control 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.
