Temporal trend of mortality by suicide among adults in Brazil: 2000 to 2015

Abstract

Objective To analyze temporal trends of mortality due to suicide among adults in Brazil, by macroregion and gender, from 2000 to 2015. Methods A retrospective study of temporal trends in suicide mortality rates in adults aged 20 to 64 years, by macroregion and gender, from 2000 to 2015. Data from the Brazilian Mortality Database (SIM) and from the Brazilian Institute of Geography and Statistics (IBGE) were used. The mortality rate trends analysis was performed using simple linear regression, with Stata 14 software. Results There was an upward trend in mortality due to intentionally inflicted self-harm in the Brazilian adult population in the North, Northeast, and Southeast regions for both genders (p<0.001), with predominance in the male population in these three regions and throughout the country (p<0.001). A downward trend was observed in the South and Midwest (p=0.003 and p=0.040). Conclusion Mortality due to intentionally inflicted self-harm has increased in Brazil, but has undergone important variations in different parts of the country. Even a regional analysis is insufficient to achieve a thorough evaluation of these contrasts because of the country’s continental proportions and data collection biases. Further studies focused on this topic are required.

Socio-demographic status and 12 years trend of completed suicide in East Azerbaijan Province, Iran, during the period 2007–2018

“…The findings of the present study were in agreement with the study in Brazil, the incidence rate of suicide has increased from 5.84 per 100,000 persons in 2000 to 7.23 per 100,000 in 2015 and represents a 19% increase in the incidence of suicide deaths over the period [13].…”

“…Drug and substance abuse and also mentalneurological problems are other reasons for high suicide rates among males [25]. The same results were found in the USA and Brazil that 72% of suicide cases were committed using firearms [13,26]. Despite that, hanging is the most commonly used suicide method globally; however, the distribution of the methods is diverse among various settings.…”

“…There are many important risk factors for completed suicide including psychiatric disorders, particularly depressive disorders, history of suicide attempts or suicidal behaviors, physical illnesses, and lack of social support and personality aspects [12,13]. In developed countries, more than 90% of suicide cases have some grade of mental illness, and among Asian countries including India and China, almost 60% of suicides have suffered from psychological disorders [10].…”
