Suicide and self-injury among the elderly are a serious public health problem.
There is evidence that diseases and mental disorders are strongly associated with
suicide in older people. For example, using psychological autopsy, between 71%
and 95% of older people who committed suicide had a diagnosis of a mental
disorder at the time of their death. Recent studies show there is a strong relationship
between suicidal attempts and carrying out the fatal act in the elderly,
which results from the interaction of complex factors: physical, mental, neurobiological
and social. In Portugal, and other countries, the highest suicide rates
are found among the elderly and especially in men. Suicide methods used in this
age group are specific, as they are more lethal and are often used in combination
to increase the odds of a fatal outcome. We present the trends in rates of suicide
in Portugal, in the period 1980 to 2009, by gender and method used, in the age
group older than 64 years comparing it to the population under 65.
