[Epidemiological analysis of suicide in Brazil from 1980 to 2006].
OBJECTIVE
The objective of this study was to carry out an epidemiological analysis of the suicide rates found in Brazilian regions and state capitals between 1980 and 2006.


METHODS
Data on mortality rates due to suicide were collected from the Departamento de Informática do Sistema Unico de Saúde (Information Technology Department of the Brazilian Public Health System--DATASUS).


RESULTS
A total of 158,952 suicide cases were registered between 1980 and 2006, excluding those cases in which the individual was less than 10 years old (n = 68). In the period under study, the total suicide rate in Brazil increased from 4.4 to 5.7 deaths per 100,000 inhabitants (29.5%). Higher average rates were found in the South (9.3) and Central-West (6.1) regions. Men were more likely to commit suicide. The highest suicide rates were found in the 70-years or above age range while the highest increases were found in the 20 to 59 year age bracket. The most dominant social-demographic characteristics of the persons who committed suicide in the period under study were low educational level and singlehood. The most common methods of suicide were hanging, fire arms and poisoning.


CONCLUSIONS
Although in Brazil the rate increased 29.5% in 26 years, the national rate is still considered to be low when compared to worldwide suicide rates (average of 4.9 per 100,000 inhabitants). Suicide rates in Brazilian regions vary broadly, ranging from 2.7 to 9.3.
