Suicide among women by the most common methods in Brazil's five major regions (2000-2019).

The aim is to analyze the temporal trend of suicide mortality among women residing in the macroregions of Brazil according to the most common incident perpetration methods from 2000 to 2019. This ecological, time-series study examines suicides among women in Brazil's five Major Regions, focusing on the methods of perpetration employed between 2000 and 2019. Data were extracted from the Mortality Information System, and techniques were applied to correct death records for coverage and information quality. Trends were assessed by negative binomial regression, classified according to the relative risk value and p-value. The perpetration methods with the highest rates in all studied locations were hanging, strangulation, and suffocation, followed by self-poisoning and firearms. In all locations, there was an upward trend for suicides by hanging, strangulation, and suffocation in all age ranges, and a downward trend for suicide by firearms and self-poisoning, except in the South region, which showed an upward trend in suicide rates by self-poisoning, and in the Midwest, which showed stability. Hanging, strangulation, and suffocation represent the main method used by women in all age ranges and regions of Brazil.
