ABSTRACT:

Objective:

To analyze mortality and years of life lost due to death or disability (disability-adjusted life years - DALYs) for interpersonal violence and self-harm, comparing 1990 and 2015, in Brazil and Federated Units, using estimates produced by the Global Burden of Disease 2015 (GBD 2015).

Methods:

Secondary data analysis of estimates from the GBD 2015, producing standardized death rates and years of life lost due to death or disability. The main source of death data was the Mortality Information System, submitted to correction of underreporting of deaths and redistribution of garbage codes.

Results:

From 1990 to 2015, homicide mortality rates were stable, with a percentage variation of -0.9%, from 28.3/100 thousand inhabitants (95% UI 26.9-32.1) in 1990 to 27.8/100,000 (95% UI 24.3-29.8) in 2015. Homicide rates were higher in Alagoas and Pernambuco, and there was a reduction in São Paulo (-40.9%). Suicide rates decreased by 19%, from 8.1/100,000 (95% UI 7.5-8.6) in 1990 to 6.6/100,000 (95% UI 6.1-7,9) in 2015. Higher rates were found in Rio Grande do Sul. In the ranking of external causes for years of life lost due to death or disability (DALYs), firearm aggression predominated, followed by transportation accidents; self-inflicted injuries were in sixth place.

Conclusions:

The study shows the importance of external causes among young people and men as a cause of premature death and disabilities, which is a priority problem in the country. The Global Burden of Disease study may support public policies for violence prevention.

INTRODUCTION

Global Burden of Disease (GBD) study estimated 973 million people injured and 4.8 million deaths from accidents and violence around the world in 2013. The main causes of death were road traffic accidents (29.1%), suicides (17.6%), falls (11.6%), and homicide (8.5%). Among the people injured, 5.8% (56.2 million) had to be hospitalized and 38.5% (21.7 million) sustained fractures11. Haagsma JA, Graetz N, Bolliger I, Naghavi M, Higashi H, Mullany EC, et al. The global burden of injury: incidence, mortality, disability-adjusted life years and time trends from the Global Burden of Disease study 2013. Inj Prev 2016; 22: 3-18..

GBD data indicate reduction in homicide rates worldwide, with regional differences. In Asia and Europe, the rates decreased, but in the Americas, East Africa, and other regions they remained high. Noteworthy is the increase of years of life lost due to death or disability (disability-adjusted life years - DALYs) in Latin America and sub-Saharan Africa, owing to homicides22. United Nations Office on Drugs and Crime (UNODC). Global study on Homicide 2013. United Nations Publication; 2014.. Suicide is the second leading cause of death from violence globally, the third in Brazil, and a major contributor to DALYs11.

In Brazil, external causes correspond to the third leading cause of death. However, in the age groups 1-49 years, they are the main cause and mostly affect young men44. Brasil.

The GBD has innovated by calculating in a comparable way, in all countries of the world, the impact of these events on mortality, in the occurrence of disabilities, in the incidence and prevalence of disease and injury77.

This study aimed at analyzing the mortality and years of life lost due to death or disability (DALYs) from interpersonal violence and self-harm, comparing 1990 and 2015, in Brazil and FUs, using estimates produced by the 2015 GBD study.

METHODS

This is a study based on secondary data used in the estimates of 2015 GBD, which applied the methodology proposed by the Institute for Health Metrics and Evaluation (IHME) at the University of Washington, United States of America1313. Institute for Health Metrics and Evaluation (IHME). Data Visualization. Disponível em: http://www.healthdata.org/results/data-visualizations (Acessado em 18 de outubro de 2016).

.

The GBD discloses on its website the data sources used in each country, which, in general, consists of vital registration, verbal autopsy, censuses, surveys, hospital data, police and forensic services records1313.

. For violent causes, reports of homicide incidents, road traffic accidents, and suicides recorded by the police are also used.

were also considered. In countries such as Brazil, which have vital registrations, police data are not used, unless the number of injuries reported in these records exceeds the vital registration. The GBD discloses the sources of information used in each country, state, or other sub-national geographical unit, adopted every year1111.

The main data source on mortality in Brazil was the death registration database of the Mortality Information System (in Portuguese, Sistema de Informações sobre Mortalidade - SIM) of the Ministry of Health, which was subject to adjustments by other national and international sources.

In the calculation of GBD estimates of external causes, a mapping of data sources on disease and injury was carried out first. Second, garbage codes were adjusted, redistributing them to defined causes. Details of the grouping by causes, using the ICD-9 and ICD-10, have been described previously1616. Lozano R, Naghavi M, Foreman K, Lim S, Shibuya K, Aboyans V, et al. Global and regional mortality from 235 causes of death for 20 age groups in 1990 and 2010: a systematic analysis for the Global Burden of Disease Study 2010. The Lancet 2012; 380(9859): 2095-128.. The GBD 2015 used the International Statistical Classification of Diseases (ICD), ninth and tenth revision: in ICD-9, E000-E999 and codes 800-999; in ­ICD-10, subgroups V01 to Y98 of Chapter XX and subgroups S00 to T98 of Chapter XIX. Third, statistical models were used and modeling were conducted to estimate data by age, sex, country, year, and cause - the Cause of Death Ensemble Modeling - CODEm. CODEm is an analytical tool that tests the variety of possible statistical models of causes of death and creates a combined set of models that offers the best predictive performance. The DisMod - MR 2.1, a meta-regression calculation tool for simultaneous estimates of incidence, prevalence, remission, disability, and mortality is used1212. GBD 2015 Mortality and causes of death collaborators.

.

In this study, the following metrics were used: mortality rates and years of life lost due to death or disability, the DALYs. This is a compound indicator that includes the premature death (years of life lost - YLL) and the damage caused by disease, sequelae, or disability, considering different levels of severity of one or more diseases simultaneously years lived with disability - YLD). In this indicator, the weight of lethal and non-lethal diseases is equivalent1818. Murray CJL, Ezzati M, Flaxman AD, Lim S, Lozano R, Michaud C, et al.

https://doi.org/10.1016/S0140-6736(12)62...
. The rates were standardized by age, and suicide indicators were calculated for individuals aged over 9 years.

The Global Burden of Disease Study (GBD Brazil 2015) was approved by the Ethics Committee of the Universidade Federal de Minas Gerais (CAAE Project -62803316.7.0000.5149).

RESULTS

In Brazil, deaths by external causes accounted for 134,931 deaths in 1990 and 168,018 in 2015, and the rates were reduced by 22.8% during the period, from 105.1 (95% UI 105.1-81.2) to 81.2/100,000 (95% UI 77.4-85.4), within the limit of significance. The main groups of causes were homicide, followed by road accidents, other accidental causes, and suicides (Table 1).

Table 1:
Frequency and standardized mortality rate (per 100,000) by accidents and violence with UI (95%), Brazil, in 1990 and 2015.

Between 1990 and 2015, homicide mortality rates were stable, with percentage change of -0.9%, varying from 28.3/100,000 inhabitants (95% UI 26.9-32.1) in 1990 to 27.8/100,000 (95% UI 24.3-29.8) in 2015. However, firearm homicides increased from 15.5 (95% UI 14.4-18.7) to 19.3/100,000 (95% UI 15.7-20.8) (27.5%), without significant difference. The rate of homicides by sharp object increased from 5.3 (95% UI 4.9-6.6) to 4.9/100,000 (95% UI 4.5-5.5), and homicides by other means varied from 7.6 (95% UI 5-8.4) to 3.6/100,000 (95% UI 3-4.3).

The homicide rates were higher in Alagoas, Pernambuco, and Espírito Santo (54.1; 43.4, and 40.4/100,000 inhabitants, respectively). Although the rates are within the uncertainty interval, they increased in several states, such as Bahia (117.9%), Rio Grande do Norte (55.6%), Ceará (53%), Minas Gerais (49.7%), Paraná (47.3%), Amapá (45%), Pará (36.1%), Paraíba (35.7%), and Alagoas (21.3%). There was a statistically significant reduction in homicides only in the state of Sao Paulo (-40.9%). The following states had important, but not statistically significant reductions: Rio de Janeiro (37.4%) and Rondônia (30.5%) (Table 2). Suicide rates varied -19%, from 8.1/100,000 (95% UI 7.5-8.6) in 1990 to 6.6/100,000 (95% UI ­6.1-7.9) in 2015, without statistically significant difference. Higher rates occurred in Rio Grande do Sul, which registered a rate of 10.5/100,000 in 2015. Rio de Janeiro was the only state with a statistically significant reduction (-58%), 5.4/100,000 (95% UI 4.8-8.1) in 1990, and rate of 4.4/100,000 (95% UI 3.0-6.9) in 2015. Other states with reduction within the uncertainty interval were Goiás (34.2%), Rondônia (33.3%), Federal District (27.8%), Pernambuco (27.2%), Paraná (27.1%), Santa Catarina (24.3%), and Rio Grande do Sul (21.6%). The most significant increases in rates were in states such as Bahia (70.6%) and Ceará (27.9%) (Table 2).

The DALYs rates from accidents and violence in 1990 and 2015, among men, show that assault by firearms (first position) and pedestrian road injuries (second position) remained with the same classification; road injuries involving motorcyclists moved from ninth positon to third position; and road injuries involving motor vehicle occupants moved from third position to fourth position. Falls remained at the fifth position. Self-harm rose from seventh to sixth position, followed by assault by sharp object (seventh position). Drowning moved from sixth to the eighth position and assaults by other means migrated from fourth to ninth position. Road injuries involving motorcyclists rose from 17th to 14th position, and unintentional firearms injuries moved from 16th to 18th position (Table 3).

Among women, data not shown, falls rose from second to first position of DALYs rates due to external causes, between 1990 and 2015, followed by pedestrians road injuries (second position) and motor vehicle occupants road injuries (third position). Homicides by firearms rose from sixth (1990) to fourth position (2015). Suicide remained at fifth position.

Table 3:
Ranking of DALYs rate/100,000, external causes, men 1990-2015.

DALYs rates by interpersonal violence and self-harm, in 2015, were higher among men than among women in all FUs, with predominance of assaults by firearms in most states except for Amapá and Roraima, where injuries by sharp objects were predominant. Self-harm was the leading cause of death among women in Roraima, Rio Grande do Sul, Piauí, Mato Grosso do Sul, Santa Catarina, Minas Gerais, São Paulo, and Rio Grande do Norte. The highest rates of DALYs by violence were registered in Alagoas, Pernambuco, and Espírito Santo, and the lowest rates were registered in Santa Catarina, São Paulo, and Piauí. Among women, the highest rates were in Roraima, Espírito Santo, and Pernambuco (Figure 1).

Figure 1:
Proportional distribution of DALYs by violence, by age group, Brazil, in 2015.

The proportional distribution of DALYs by age, according to interpersonal violence and self-harm, in 2015, indicates higher frequency of cases in the younger age groups, by order of importance, in age groups 20-24 years, 15-19 years, 25-29 years, and 30-34 years. Except for age group 0-4 years, in which assaults by other means are prevalent. In other age groups, assaults by the firearm and sharp objects are predominant (Figure 2).

DISCUSSION

The study shows the magnitude of external causes in the country, which was the third cause of death in 2015. Between 1990 and 2015, these causes were reduced by a quarter. Among the external causes, homicides predominate, followed by road injuries, other accidental causes, and suicides. Homicides remained stable during the period; however, with large variations between states. São Paulo was the only state with a statistically significant reduction during the period. In several other states, although the rates are within the uncertainty interval, they had an increase, such as in Bahia, Rio Grande do Norte, Ceará, and Minas Gerais. Suicide rates decreased by approximately a quarter, within the uncertainty range. In the ranking of external causes for years of life lost due to death or disability (DALYs), assaults by firearms are predominant, followed by road injuries. Suicides were in the sixth position. The proportional distribution of DALYs by interpersonal violence and self-harm, in 2015, indicate higher frequency among men and in young age groups, especially between 20 and 24 years of age, followed by young people aged 15-19 years. The highest rates of DALYs by violence in men occurred in Alagoas, Pernambuco, and Espírito Santo.

Brazil is simultaneously part of the groups of countries with higher risk of death by homicide and with lower suicide rates, according the World Health Organization reports1919.

. In high-income countries, the decrease in homicide rate was 39%; in middle-income countries, the decline was 13%; and in low-income countries, the decrease in the rate was equal to 10%. In a report from the United Nations (UN) in 2012, it was estimated that in Latin America and the Caribbean the majority of deaths from external causes occurred by homicides, and three quarters of them were caused by firearms. In South America, Brazil has the third highest homicide mortality, after Venezuela and Colombia1414. United Nations Office On Drugs and Crime (UNODC).

. The risk of homicide is ten times higher than that of high-income countries such as France and the United States of America (rates below 3/100,000), and Latin American countries with low and middle income, such as Argentina and Mexico (3 to 7 per 100,000)1212.

The pattern of occurrence of homicide and suicide shows different aspects in the country, with significant differences by gender, age, and FUs. Violence, in general, is more common among young men, predominantly homicides by firearms in the northeast and north regions. Although within the significance limits, states such as Minas Gerais and Paraná registered rates which differed from that observed in their regions, considering the declining rates in Sao Paulo and stable rates in the other states of the south and southeast regions. A previous study identified increased risk of homicide in cities of Paraná State, which are located close to the border between other countries, possibly owing to greater availability of firearms and illegal drugs2222. Andrade SM, Soares DA, Souza RKT, Matsuo T, Souza HD. Homicídios de homens de quinze a 29 anos e fatores relacionados no estado do Paraná, de 2002 a 2004. Ciênc Saúde Coletiva 2011; 16(1): 1281-8..

Homicide victims are usually young adult men (aged 20-34 years) and adolescents (aged 15-19 years) and residing mainly in the northeast and north regions, murdered with firearms. This pattern of mortality are in accordance with other studies on violence, which evidence the main victims as being men, young, black, and poor2121. Reichenheim ME, Souza ER, Moraes CL, Mello-Jorge MHP, Silva CMFP, Minayo MCS.

Evolução da mortalidade por homicídio no Estado da Bahia, Brasil, no período de 1996 a 2010. Ciênc Saúde Colet 2014; 19(6): 1889-900.. In Brazil, men are 9.2 times more likely to die from homicide than women, which can be partially explained by cultural issues that encourage male violence. The profile of murdered women is also of young victims and, similar to men, death is caused by firearms. In an urban northeast center, the main profile of women murdered is young, black, and single, with low education and income, and they are victims of physical and/or sexual violence2525.

Studies on violence, particularly homicides, show that violent behaviors are exacerbated in conditions of structural inequality, in degraded urban areas and outskirts of cities, and are more common among people with low education and income, who use alcohol and drugs, who are involved in trafficking and illegal possession of weapons, and who experience fragile family ties. There is also the victimization by domestic violence, unemployment, precarious education and public safety, as well as police violence. Conflicts in areas of agricultural borders and land disputes are also mentioned2121. Reichenheim ME, Souza ER, Moraes CL, Mello-Jorge MHP, Silva CMFP, Minayo MCS.

The presence of armed conflict zones, rivalry, and dispute in trafficking accentuate the risk of deaths from assault, promoting the “ecology of danger” (prevalence of male violence, availability of weapons, coercion, and domination over territories). High homicide rates have been explained by the high concentration of weapons and poor young men4444. Barcellos C, Zaluar A. Homicídios e disputas territoriais nas favelas do Rio de Janeiro.

Suicide is among the top ten causes of death worldwide, with more than 800,000 deaths each year. It is estimated 20 attempts for each adult who commits suicide and approximately a third of them have a history of repeated attempts2020. World Health Organization (WHO).

Data from the GBD 2015 indicate the largest global suicide rates in Asia (13.3/100,000) and Europe (17.6/100,000). The Americas have suicide rate of 9.8/100,000, compared with countries such as Russia (36.8/100,000), India (15.8/100,000), and South Africa (14.8/100,000). Brazil is included in the group with lower suicide rates1212. GBD 2015 Mortality and causes of death collaborators.

Sex, age, culture, and ethnicity have significant implications in the epidemiology of suicide in the world. Consummated suicides among men are more frequent than among women. In this study, the DALYs rates for suicides were higher among men, if compared with women, and among young people aged 15-34 years. The rates of death by suicide are higher among people aged over 70 years2020. World Health Organization (WHO). Preventing suicide: a global imperative. Washington, D.C.: WHO; 2014.

Many factors were related to suicide, such as mental disorders (depression, alcoholism, schizophrenia) and sociodemographic characteristics (male, unemployed person, urban residents, retirees, migrants, and singles)5252. World Health Organization (WHO). The word health report. Shaping the future. Genebra: OMS; 2003.. Other conditions are also related to social aspects as follows: personal loss, violence, social isolation, interpersonal conflicts, legal, or labor issues5252. World Health Organization (WHO). The word health report. Shaping the future. Genebra: OMS; 2003.,5353. Ponce JC, Andreuccetti G, Jesus MGS, Leyton V, Muñoz DR. Álcool em vítimas de suicídio em São Paulo. Rev Psiquiatr Clín 2008; 35(1): 13-6., and specifically in childhood and adolescence, physical and sexual abuse, and difficulties with sexual orientation5454. Evans E. The prevalence of suicidal phenomena in adolescents: a systematic review of population-based studies. Suicide and Life - Threatening Behavior 2015; 35(3): 239-50.,5555. Baggio L, Palazzo LS.

States of southern Brazil are included in the group with higher incidence of suicide; and Rio Grande do Sul stands out for higher mortality and DALYs rates, which are supported by other studies5656. Ferreira VRT, Trichês VJS. Epidemiological Profile of Suicide Attempts and Deaths in a Southern Brazilian City. Psico 2014; 45(2): 219-27.,5757. Viana GN, Zenkner FM, Sakae TM, Escobar BT. Prevalência de suicídio no Sul do Brasil, 2001-2005. J Bras Psiquiatr 2008; 57(1): 38-43.. Deaths are more common in rural areas of the state, and among the predisposing factors are socioeconomic, educational, particularly historical and cultural aspects, as well as those related to working conditions, among others.

Estimates of the GBD 2015 study advanced methodologically in various aspects such as the standardization of data and correction of underreporting and garbage codes, which enabled the comparison between periods, countries, and between the states of Brazil.

There are limitations related to the data sources accessed. Although the SIM has broadened the collection of records and improved their quality in recent years, in the past, and even in some states, there are deaths that were not registered, incomplete records, and high proportion of garbage codes. Studies5858. Szwarcwald CL, Morais Neto OL, Frias PG, Souza Júnior PRB, Escalante JJC, Lima RB, et al. Busca ativa de óbitos e nascimentos no Nordeste e na Amazônia Legal: estimação das coberturas do SIM e do Sinasc nos municípios brasileiros. Brasil. Ministério da Saúde (MS). Saúde Brasil 2010: uma análise da situação de saúde. Brasília: MS; 2011. p. 79-97.,5959. França E, Teixeira R, Ishitani L, Duncan BB, Cortez-Escalante JJ, Morais Neto OL, et al. Causas mal definidas de óbito no Brasil: método de redistribuição baseado na investigação do óbito. Rev Saude Pública 2014; 48(4): 671-81. have highlighted the need for SIM correction and recommended using adjustment methodologies, such as the active search for deaths. Other limitation is the difference between SIM and GBD data with respect to the data on legal interventions. GBD did not register deaths from legal intervention in Brazil in 2015, and this needs improvement in future editions.

CONCLUSION

The study highlights the differences between the states, the importance of external causes as causes of premature death and disability among young people, and evidences the need to implement policies and measures to reverse this situation. Violence in Brazil is a complex phenomenon that has historical roots and is sustained by the great social inequalities. Any attempt to cope with violence needs to be based on a policy for promotion of life, which requires an interdisciplinary approach with inclusive social policies, implemented in partnership with health area, which may apply its practices of surveillance and care. In Brazil, the actions to manage the violence in recent years have been implemented through coordinated public policies. However, much more must be done to reduce deaths and injuries from violence. Therefore, this needs to be a priority cause of managers, professionals, and society.

The results of the GBD study are a valuable resource for countries seeking to prioritize the management of the main risk factors of deaths and injuries and increase effective actions for the health of the population.
