Core Tip

Core Tip: Suicide constitutes a global health concern. In this regard, suicide is one of the leading ten causes of death in five of the 21 Global Burden of Disease defined regions. Suicide mortality is more prevalent in older adults in comparison to younger adults, due to the cumulated influence of multiple risk factors over time. The role of depression in late-life suicide deserves particular interest due to its elevated prevalence and relationship with functional disability and chronic disease development. Results from this study may contribute to planning intensive assessment protocols in older adults with depression to target suicide, as well as to monitoring suicide behaviour as a key indicator of depression treatment success.
