Suicide in indigenous and non-indigenous population: a contribution to health management

Suicidio en la población indígena y no indígena: una contribución para la gestión en salud

ABSTRACT

Objective:

To analyze the sociodemographic and epidemiological profile of suicide in the indigenous and non-indigenous population and the spatiality of the event.

Method:

Epidemiological, descriptive research, carried out with data from the Mortality Information System. Suicide mortality rates were calculated for the 144 municipalities in Pará and linked to the geographic location values of the municipalities; subsequently, thematic maps were built using the QGIS 3.10.3 software. The association between variables was measured by the G test.

Results:

1,387 suicide records were studied, and the mortality rate among indigenous people was low in comparison to non-indigenous people, reaching 0.1/100 thousand inhabitants and 17.5/100 thousand inhabitants, respectively.

Conclusion:

Suicide is heterogeneously distributed in the territory, with greater vulnerability of the indigenous people, which demands different policies considering their cultural diversity.

INTRODUCTION

Suicide has been described as an increasingly frequent problem in social spaces, representing an important public health issue that affects individuals from different population groups, age groups, sex, and religions (11 Ribeiro NM, Castro SS, Scatena LM, Haas VJ. Time-trend analysis of suicide and of health information systems in relation to suicide attempts. Texto Contexto Enferm. 2018;27(2):e2110016. doi: 10.1590/0104-070720180002110016

https://doi.org/10.1590/0102-311X0001921...
). Data from the World Health Organization (WHO) indicates that more than 800 thousand people die every year worldwide because of this event, which means one death every 40 seconds (44 World Health Organization. Mental health: Suicide data[Internet]. 2019[cited 2019 Nov 28]. Available from: http://www.who.int/mental_health/prevention/suicide/suicideprevent/en/
http://www.who.int/mental_health/prevent...
).

In Brazil, suicide is among the top ten causes of death, being the third among people aged 20 to 39 years (55 Mata KCR, Daltro MR, Ponde MP. Perfil epidemiológico de mortalidade por suicídio no Brasil entre 2006 e 2015. Rev Psicol Divers Saúde. 2020;9(1):74-87. doi: 10.17267/2317-3394rpds.v9i1.2842
https://doi.org/10.17267/2317-3394rpds.v...
). In the period from 2011 to 2015, across the country, there were 55,649 deaths from suicide, with a rate of 5.5/100 thousand inhabitants, varying from 5.3/100 thousand inhabitants in 2011 to 5.7/100 thousand inhabitants in 2015. The highest rates were observed in people aged 70 and over, reaching 8.9/100 thousand inhabitants (66 Ministério da Saúde (BR). Secretaria de Vigilância em Saúde. Suicídio. Saber, agir e prevenir. Bol Epidemiol[Internet]. 2017 [cited 2019 Sep 28];48(30):1-15.

ttp://portalarquivos.saude.gov.br/images...
).

For the indigenous population, in the same period from 2011 to 2015, the suicide rate was 15.2/100 thousand inhabitants. The highest proportion was identified among adolescents aged 10 to 19, corresponding to 44.8% of the total recorded in the period, a value eight times greater than that observed among whites and blacks, which was 5.7% for each group (66 Ministério da Saúde (BR).

).

Indigenous suicide has increased in recent years. Data provided by the Special Secretariat for Indigenous Health (SSIH) indicate that, in the Special Indigenous Health District (SIHD) of Mato Grosso do Sul, there were 782 deaths from self-harm between 2000 and 2016, which may be related to the difficulty in the integration process with western society, as well as the social vulnerability issues to which they are submitted (77 Conselho Indigenista Missionário.

Deaths by suicide can differ between ethnic groups and between urban and rural areas, referring to the social and cultural dimension (88 Souza MLP, Onety Jr RTS. Characteristics of suicide mortality among indigenous and non-indigenous people in Roraima, Brazil, 2009-2013. Epidemiol Serv Saúde. 2017;26(4):887-93. doi: 10.5123/S1679-49742017000400019

https://doi.org/10.1590/0102-311X0009281...
). The heterogeneous geographic distribution of suicide has persisted over time, both in countries and in the geographic spaces within the same country, which led to the hypothesis that suicide is correlated with the territory (1111 Mota AA.

).

The analysis of events considering the geographical area in which they occur has been increasingly valued in health management, as it provides better knowledge of their distribution in space, contributing to the identification of areas where a priority can be given for intervention (1414 Santos, EGO, Barbosa IR, Severo AKS. Análise espaço-temporal da mortalidade por suicídio no Rio Grande do Norte, Brasil, no período de 2000 a 2015. Ciênc Saúde Coletiva. 2020;25(2):633-43. doi: 10.1590/1413-81232020252.11042018

https://doi.org/10.17696/2318-3691.23.4....
).

OBJECTIVE

Analyze the sociodemographic and epidemiological profile of suicide in the indigenous and non-indigenous population and the spatiality of the event.

METHODS

Ethical aspects

The study complied with the recommendations of Resolution No. 466/12 - CNS/MS, which regulates research involving human beings, approved by the Research Ethics Committee of the Undergraduate Nursing Course at the State University of Pará (UEPA).

Design and place of study

An epidemiological, descriptive study, using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) (1616 Von Elm E, Altman DG, Egger M, Pocock SJ, Gøtzsche PC, Vandenbroucke JP, STROBE Initiative. The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement: guidelines for reporting observational studies. J Clin Epidemiol. 2008;61(4):344- 9. doi: 10.1016/j.jclinepi.2007.11.008
https://doi.org/10.1016/j.jclinepi.2007....
) as a methodological guide, conducted in the state of Pará, in the Amazon region of Brazil. Pará consists of 144 municipalities and concentrates 34 indigenous ethnic groups distributed in 298 villages, totaling approximately 39,081 indigenous people (1717 IBGE. Instituto de Geografia e Estatística. Censo Demográfico 2010. Rio de janeiro: IBGE, 2010. [Cited 2019 out 15]. Available from: http://censo2010.ibge.gov.br
http://censo2010.ibge.gov.br...
).

Study population and period

The study population was of 1,387 suicide cases reported in the municipalities of the state of Pará from 2010 to 2015 and whose basic cause was coded as intentional self-harm (codes X60 to X84), according to the International Statistical Classification of Diseases and Health Problems (ICD-10).

Data collection and source

Suicide cases in the municipalities of the state of Pará were collected in the Mortality Information System (MIS), made available by the Health Surveillance Coordination (HSC) of the State Secretariat of Public Health of Pará (SSPHP).

For the calculation of the mortality rate, we used estimated data for the population of the years 2011, 2012, 2013, 2014, and 2015, made available by DATASUS (Information Technology at the service of the Brazilian Unified Health System referred to as SUS) (1818 Ministério da Saúde (BR). Secretaria-Executiva. Departamento de Informática do SUS. Tecnologia da Informação a serviço dos SUS (DATASUS) [Internet]. 2019 [cited 2019 Oct 19]. Available from: http://tabnet.datasus.gov.br/cgi/deftohtm.exe?/cnv/poptbr.def
http://tabnet.datasus.gov.br/cgi/deftoht...
). And the 2010 population data was taken from the 2010 census (1919 Instituto de Geografia e Estatística (IBGE). Censo Demográfico 2010 [Internet]. 2010 [cited 2019 Oct 30]. Available from: ftp://ftp..gov.br/Censos/Censo_Demografico_2010/Resultados_do_Universo/xls/Municipios/para.zip
ftp://ftp..gov.br/Censos/Censo_Demografi...
). Also, from the Brazilian Institute of Geography and Statistics (IBGE)(2020 Instituto de Geografia e Estatística. Shapefiles Pará [Internet]. 2010 [cited 2019 Dec 13]. Available from: ftp://geoftp..gov.br/organizacao_do_territorio/malhas_territoriais/malhas_municipais/municipio_2015/
ftp://geoftp..gov.br/organizacao_do_terr...
), shapefiles were obtained for the preparing of the maps.

Data analysis

After the database was made available by the SSPHP’s HSC, the file was structured in Microsoft Office Excel® 2010 and then the variables were organized: municipality of residence; sex; age; marital status; and schooling. The data were grouped into two banks according to race/color, identifying indigenous and non-indigenous people. Subsequently, the analysis was structured in two stages: statistical analysis and spatial analysis.

For the statistical analysis, mortality rates were calculated by the expression: Number of suicides/absolute population × 100 thousand inhabitants. The population data was the result of the average number of inhabitants for each year of the studied period, using population estimates and the 2010 demographic census of the IBGE. A 95% confidence interval (95% CI) was considered.

Then, demographic characterization was performed based on the following variables: sex; marital status; schooling; and age. The G test was used to compare the proportions of the demographic variables of indigenous and non-indigenous groups. Statistical significance was set at p < 0.05, and the analyzes were performed using the Bioestat 5.0 software.

For spatial analysis, the Federative Unit, that is, the state of Pará, was established as a territorial section, and as a geographical unit of analysis, the municipality. Thus, the 144 municipalities in Pará were studied. The mortality rate was calculated using data stratified in two trienniums (2010 to 2012 and 2013 to 2015), whose values were obtained by the sum of the cases (indigenous and non-indigenous) of each triennium divided by the population median of the triennium, calculated by the IBGE estimate for each year and multiplied by 100,000 inhabitants, according to the formula (2121 Organização Pan-Americana da Saúde. Indicadores de saúde. Elementos conceituais e práticos. Washington D.C.: OPAS; 2018.):

Rate non indigenous = 1 T ˜ T C non indigenous * 100000 Rate indigenous = 1 T ˜ T C indigenous * 100000

Where T is the triennium, is the median population for the triennium, and C is the number of cases.

To standardize the occurrence of suicide according to sex and age, indirect standardization was used under the justification of a considerable difference between the orders of magnitude of the indigenous and non-indigenous populations. The calculation of the standardized rate was performed according to Lwanga(2222 Lwanga SK, Tye CY, Ayeni O. Teaching health statistics: lesson and seminar outlines, 2nd ed. Geneva, World Health Organization, 1999.):

S tan dardized rate i = FP i x IM i FP i = Rate Non indigenous IM i IM i = Σ j P ij x Rate j P i x 100 , 000

We have i as an indicator of indigenous population, FP corresponds to the standardization factor, IM corresponds to the mortality index, and Rate and P are the mortality rate and the population for each evaluated segment, respectively.

The calculation of the crude rate for comparative analysis followed the formula:

Crude rate i = Σ j x Suicide cases i P i x 100 , 000

For population, data segmented by color/race, sex, and age group provided by the 2010 Demographic Census (Table 3175 - available at https://sidra.ibge.gov.br/Tabela/3175) were used, under the premise that there was no significant variation in the age and sex profile of the populations evaluated. The 12 suicide observations that did not have information on age group and, one case without information on sex, were disregarded in this calculation, as these data referred to the group of non-indigenous people.

The suicide mortality rates for each municipality were linked to the geographic location values (latitudes and longitudes) of each municipality, obtained from the IBGE website, which allowed the construction of thematic maps using the QGIS 3.10.3 software. The rates were grouped into five ranges, both for indigenous and non-indigenous, and categorized based on the criteria suggested by Diekstra and Gulbinat(2323 Diekstra RFW, Gulbinat W. The epidemiology of suicidal behavior: a review of three continents. World Health Statist Quat [Internet]. 1993[cited 2019 Dec 13];46(1):52-68. Available from: https://apps.who.int/iris/handle/10665/48670

) in: null; low (0.1-4.9); average (5.0-14.9); high (15.0-29.9); and very high (> 30.0).

RESULTS

1,387 suicide cases were analyzed during the study period. According to Table 1, the suicide mortality rate for the non-indigenous population was 17.5/100 thousand inhabitants, with an average of 231 cases each year (CI 229.6 - 232.3), with the highest rate in 2015 with 3.8/100 thousand inhabitants. Regarding the indigenous population, the mortality rate was 0.1/100 thousand inhabitants, (CI 0.3 - 1.6) with low rates.

Table 1
Suicide incidence rate among indigenous and non-indigenous populations in the state of Pará, from 2010 to 2015, Pará, Brazil, 2019

Table 2 shows the sociodemographic profile of suicide in the two groups studied. It was identified that the proportion of the event in the non-indigenous population was higher among men, with 80.43% (n = 1,110 cases); and in the indigenous population, among women, corresponding to 57.14% (n = 4) of the cases.

Table 2
Distribution of suicide cases among indigenous and non-indigenous populations, according to sociodemographic variables, 2010-2015, Pará, Brazil, 2019

Regarding the age group, it was found that, among non-indigenous people, 28.99% (n = 400) of the cases occurred in people aged between 20 and 29 years, while in the indigenous population, the largest number of cases occurred in the age groups between 30 and 39 years, and 80 years or more, both with 28.57% (n = 2).

Regarding marital status, the results showed that suicide prevailed among individuals that were single in both populations, corresponding to 61.59% (n = 850) among non-indigenous people and 57.14% (n = 4) among indigenous people.

In regard to education, a greater expressiveness was observed among those with 4 to 7 years of study, with 29.06% (n = 401) of the total cases. For the indigenous population, the data showed a predominance among individuals with no education with 28.57% (n = 2). It is important to highlight the considerable number of non-filled “schooling” field in the data for the indigenous population, adding to a total of 28.57% (n = 2).

According to Table 3, the comparison of crude rates with standardized rates, by age group, allows us to identify that indigenous people have a higher calculated value. The composition of populations according to age group shows a higher proportion of non-indigenous individuals in the groups with the highest suicide rates (from 20 years old). This would justify the higher crude rate of non-indigenous people.

Table 3
Suicide mortality rate in the indigenous and non-indigenous population, standardized by age group and sex, 2010-2015, Pará, Brazil, 2019

The standardization according to sex did not show any changes, indicating that the composition of both populations is similar, showing little influence when comparing.

The stratified rates showed that, for the three-year period, from 2010 to 2012, for the indigenous population, the highest values were in the municipalities of Alenquer, Itaituba, Cametá, and Tucumã, ranging from 0.1/100 thousand inhabitants to 4.9/100 thousand inhabitants; and for the three-year period, from 2013 to 2015, the municipalities with the highest suicide rates were Altamira, Jacareacanga, and Portel (Figure 1). In both periods, rates were classified as low.

Figure 1
Mortality rate due to suicide in the indigenous and non-indigenous population of the state of Pará by municipality, in the period of 2010-2015, Pará, Brazil, 2019

For the non-indigenous population, in the period of 2010 to 2012, suicides were recorded in 73.61% of the municipalities in Pará, highlighting the high rates in the municipalities Abel Figueiredo (29.2/100 thousand inhabitants), Brejo grande do Araguaia (27.4/100 thousand inhabitants), Cumaru do Norte (27.2/100 thousand inhabitants), and Moju (28/100 thousand inhabitants). During this study period, the municipalities in the very high range were Rio Maria (33.9/100 thousand inhabitants) and Palestina do Pará (40.3/100 thousand inhabitants).

In the three-year period, from 2013 to 2015, the data indicate a significant increase in suicide mortality rates in municipalities previously classified in the middle range, which migrated to the high range, namely: Altamira, Novo Progresso, Portel, Uruará, and Paragominas.

DISCUSSION

The analysis of the data allowed to identify that, in the studied period, the indigenous people had lower suicide rates, causing the occurrence of possible underreporting in the records(88 Souza MLP, Onety Jr RTS. Characteristics of suicide mortality among indigenous and non-indigenous people in Roraima, Brazil, 2009-2013. Epidemiol Serv Saúde. 2017;26(4):887-93. doi: 10.5123/S1679-49742017000400019

https://doi.org/10.26633/RPSP.2020.58...
). There was also evidence of heterogeneity of rates in the geographic spaces of the municipalities of Pará.

Regarding the dynamics of the event’s occurrence in Brazil, although data points to higher rates in the South Region(2424 Malta DC, Minayo MC, Soares Filho AM, Silva MMA, Montenegro MMS, Ladeira RM, et al.

Spatial analysis and temporal trends of suicide mortality in Sergipe, Brazil, 2000-2015. Trends Psychiatry Psychother. 2018;40(4):269-76. doi: 10.1590/2237-6089-2017-0028
https://doi.org/10.1590/2237-6089-2017-0...
) identified an increase of 102.3% in the suicide mortality rate between 2000 and 2015, from 2.69/100 thousand inhabitants in 2000 to 5.44/100 thousand inhabitants in 2015. In the North Region, there was an increase from 3.8/100 thousand in the year 2000 to 5.3/100 thousand in the year 2012, impacting the national indexes(2828 Corassa RB, Falci DM, Gontijo CF, Machado GVC, Alves PAB. Evolução da mortalidade por causas externas em Diamantina (MG), 2001 a 2012. Cad Saúde Colet. 2017;25 (3):302-14. doi: 0.1590/1414-462X201700030258
https://doi.org/0.1590/1414-462X20170003...
). This scenario has contributed to changes in the pattern of morbidity and mortality of the Brazilian population in recent years, which has been registering a decline in mortality from infectious diseases and an increase in external causes, including suicide(2626 Santos EGO, Barbosa IR. Conglomerados espaciais da mortalidade por suicídio no nordeste do Brasil e sua relação com indicadores socioeconômicos. Cad Saúde Colet. 2017;25 (3):371-8. doi: 10.1590/1414-462X201700030015
https://doi.org/10.1590/1414-462X2017000...
).

The analysis of the “sex” variable denotes a predominance among men for non-indigenous population and in women for indigenous, although the standardized rate has indicated similarity in the occurrence of the event in both population groups. The identified result draws attention, since the literature refers to higher rates among men in the two groups studied and points out that, in the female population, the rates are higher in relation to suicide attempt whose outcome does not always correspond to death(88 Souza MLP, Onety Jr RTS. Characteristics of suicide mortality among indigenous and non-indigenous people in Roraima, Brazil, 2009-2013. Epidemiol Serv Saúde. 2017;26(4):887-93. doi: 10.5123/S1679-49742017000400019

https://doi.org/10.1590/2237-6089-2017-0...
). In this sense, the study carried out in Roraima, when analyzing suicide between indigenous and non-indigenous people, identified in the first group rates of 20.3/100 thousand for men and 9.3/100 thousand for women; and among non-indigenous people, rates of 12.9 and 4.2/100 thousand, for men and women, respectively(88 Souza MLP, Onety Jr RTS. Characteristics of suicide mortality among indigenous and non-indigenous people in Roraima, Brazil, 2009-2013. Epidemiol Serv Saúde. 2017;26(4):887-93. doi: 10.5123/S1679-49742017000400019
https://doi.org/10.5123/S1679-4974201700...
).

The higher occurrence among men indicates coherence with the explanations about male behaviors related to competitiveness, greater aggressiveness, as well as easy access to firearms, and difficulties in facing unfavorable economic situations(2828 Corassa RB, Falci DM, Gontijo CF, Machado GVC, Alves PAB. Evolução da mortalidade por causas externas em Diamantina (MG), 2001 a 2012. Cad Saúde Colet. 2017;25 (3):302-14. doi: 0.1590/1414-462X201700030258

https://doi.org/10.1590/1413-81232018231...
). Strengthening this analysis, studies report that women present a lower alcohol dependency, more religiosity, early perception of risk signs for depression and mental illness by using the health service and help networks in times of crisis(11 Ribeiro NM, Castro SS, Scatena LM, Haas VJ. Time-trend analysis of suicide and of health information systems in relation to suicide attempts. Texto Contexto Enferm. 2018;27(2):e2110016. doi: 10.1590/0104-070720180002110016

https://doi.org/10.1590/1982-37030032216...
).

Another important factor to be valued is related to the suicide modalities chosen by men, with the use of firearms and hanging, as they present greater lethality. Women use more intoxication methods by poison or medication. This would explain the higher mortality among men and the many attempts among women(2929 Orellana JD, Balieiro AA, Fonseca FR, Basta PC, Souza MLP.

).

In this study, there was a significant number of suicide cases in young adults, aged between 20 and 39 years, both in indigenous and non-indigenous groups, with an additional for the indigenous population of the event in the elderly over 80 years. The comparison between crude and standardized rates indicated a larger dimension of the event in older age groups in the group of non-indigenous people. In this sense, although researchers(99 Souza RSB, Oliveira JC, Alvares-Teodoro J, Teodoro MLM. Suicídio e povos indígenas brasileiros: revisão sistemática.

) attribute suicide to the socio-cultural context in which people are inserted, strengthening the idea of the influence of the environment in its occurrence, the reasons that lead to the practice of suicide may vary depending on age group.

Among young people and adults, disruption of relationships, difficulties in entering the labor market, socioeconomic factors, difficulties in adapting to contemporary transformations, family instability, and excessive consumption of alcohol and other drugs are the main causes(11 Ribeiro NM, Castro SS, Scatena LM, Haas VJ. Time-trend analysis of suicide and of health information systems in relation to suicide attempts. Texto Contexto Enferm. 2018;27(2):e2110016. doi: 10.1590/0104-070720180002110016

https://doi.org/10.1590/1414-462X2018000...
). And in the elderly population, suicide is attributed to abandonment by family members, social isolation, the emergence of chronic diseases, loss of loved ones, and the proximity of death(3636 Pereira MM. Representações de suicídio indígena no Amazonas: o que desencadeia a vontade de morrer? Diversitates Int J [Internet]. 2017 [cited 2019 Dec 17];09(1):03-26.

https://doi.org/10.1590/S0104-1290201614...
).

Regarding marital status, singles had the highest rates in both ethnic groups, confirming the results described in the literature (88 Souza MLP, Onety Jr RTS. Characteristics of suicide mortality among indigenous and non-indigenous people in Roraima, Brazil, 2009-2013. Epidemiol Serv Saúde. 2017;26(4):887-93. doi: 10.5123/S1679-49742017000400019

https://doi.org/10.1590/1414-462X2018000...
), leading to the inference that the “single” variable is a contributing factor to the practice of suicide in both populations. In this sense, it is admitted that the absence of an affective bond contributes to emotional vulnerability, making it difficult to cope with adverse everyday situations, which makes the individual more prone to the practice of self-harm(2929 Orellana JD, Balieiro AA, Fonseca FR, Basta PC, Souza MLP. Spatial-temporal trends and risk of suicide in Central Brazil: an ecological study contrasting indigenous and non-indigenous populations. Rev Bras Psiquiatr. 2016;38(3):222-30. doi:10.1590/1516-4446-2015-1720
https://doi.org/10.1590/1516-4446-2015-1...
). It is important to emphasize that family ties, work, and social obligations strengthen people by reducing their weaknesses and, consequently, their vulnerability to suicide(3333 Ribeiro JF, Mascarenhas TB, Araújo ACBS, Coelho DMM, Brancas ABP, Coelho DMM. Perfil sociodemográfico da mortalidade por suicídio. Rev Enferm UFPE. 2018;12(1):44-50. doi: 10.5205/1981-8963-v12i01a25087p44-50-2018
https://doi.org/10.5205/1981-8963-v12i01...
).

The level of education, likewise, is a relevant variable in studies on suicide, showing itself associated with the event, although with different analyzes for the two groups studied. Among indigenous people, suicide proved to be more expressive in people with no schooling and with few years of study, reinforcing other research, in view of the low schooling profile present in indigenous communities. This situation is attributable to the restricted access to formal education, which is still a factor in Brazil(88 Souza MLP, Onety Jr RTS. Characteristics of suicide mortality among indigenous and non-indigenous people in Roraima, Brazil, 2009-2013. Epidemiol Serv Saúde. 2017;26(4):887-93. doi: 10.5123/S1679-49742017000400019

https://doi.org/10.1186/s12916-018-1115-...
).

In this context, the high number of notifications where the data age field was not filled in, this population group stands out. The incompleteness of the records in the information system precludes further analysis of the problems, making it difficult to understand the real scenario and, consequently, to plan preventive actions. In this specific case, we can argue that such a gap in filling is due to the difficulty of obtaining the data from the informant at the time of death registration.

In this study, among non-indigenous people, the suicide rate predominated in people with 4 to 7 years of study, considered to be a low educational level. It is admitted that people with less education usually experience low socioeconomic conditions, greater social exclusion and, therefore, greater impairment of individual and family quality of life. The level of education, insertion in the job market, and family income define the social and economic status of the individual, exposing him to different levels of stress(2323 Diekstra RFW, Gulbinat W. The epidemiology of suicidal behavior: a review of three continents. World Health Statist Quat [Internet]. 1993[cited 2019 Dec 13];46(1):52-68. Available from: https://apps.who.int/iris/handle/10665/48670
https://apps.who.int/iris/handle/10665/4...
).

Nevertheless, higher levels of education are described in the literature as social variables capable of potentiating the risk of suicide, given that individuals belonging to higher social groups would be prone to work with higher levels of stress(3333 Ribeiro JF, Mascarenhas TB, Araújo ACBS, Coelho DMM, Brancas ABP, Coelho DMM. Perfil sociodemográfico da mortalidade por suicídio. Rev Enferm UFPE. 2018;12(1):44-50. doi: 10.5205/1981-8963-v12i01a25087p44-50-2018

https://doi.org/10.1590/1981-22562017020...
). The results obtained in this study demonstrated an association between suicide and low education.

With regard to the geographical distribution of suicide in the state of Pará, the rates of occurrence among indigenous people were more expressive, and may be related to conflicts of the most diverse orders, such as: intense approximation with the urbanized population; cultural influence of other ethnic groups; loss of territories; greater exposure to drugs and alcohol(77 Conselho Indigenista Missionário.

https://doi.org/10.1186/s12916-018-1115-...
). A study carried out in the state of Amazonas highlighted high suicide mortality rates among indigenous people in the municipalities of Santa Izabel do Rio Negro (36.4/100 thousand inhabitants), São Gabriel da Cachoeira (27.6/100 thousand inhabitants), and Tabatinga (25.2/100 thousand inhabitants), possibly due to the increased consumption of alcoholic beverages on weekends, considering that, individuals under the influence of alcohol are more likely to lose their abilities of judgement, self-control, and critical sense and, thus, tend to adopt aggressive behaviors (1010 Palma DCA, Santos ES, Ignotti. Análise dos padrões espaciais e caracterização dos suicídios no Brasil entre 1990 e 2015. Cad Saúde Pública. 2020;36(4):e00092819. doi: 10.1590/0102-311X00092819
https://doi.org/10.1590/0102-311X0009281...
).

Indigenous suicide has attracted the attention of scholars, who have linked it with aspects of the cultural devaluation that these people have suffered over the years, inefficiency of differentiated assistance offered by the health sector, social injustices and even loss of their identities(77 Conselho Indigenista Missionário. Violência contra os povos indígenas no Brasil [Internet]. 2016 [Cited 2019 Oct 15]. Available from: http://www.cimi.org.br/pub/Relatorio2016/relatorio2016.pdf

https://doi.org/10.22199/S07187475.2016....
). The cultural factor, therefore, would act synergistically, considering that indigenous culture is based on immediate behavior, that is, without the planning of goals and of future life, hence, life would feel as having little value(1010 Palma DCA, Santos ES, Ignotti. Análise dos padrões espaciais e caracterização dos suicídios no Brasil entre 1990 e 2015. Cad Saúde Pública. 2020;36(4):e00092819. doi: 10.1590/0102-311X00092819
https://doi.org/10.1590/0102-311X0009281...
).

Suicide for indigenous people can mean a way to end the suffering, conflicts and anguish that are being experienced. The difficulty of adapting individuals from this ethnic group to urban areas has also been described in the scientific literature as a potentializing factor for the practice of self-inflicted violence(3434 Cunha FA, Baptista MN, Carvalho LF. Análise documental sobre os suicídios ocorridos na região de Jundiaí entre 2004 e 2014. Salud Soc. 2016;7(2):212-22. doi: 10.22199/S07187475.2016.0002.00006.
https://doi.org/10.22199/S07187475.2016....
,4040 Azuero AJ, Arreaza-Kaufman D, Coriat J, Tassinari S, Faria A, Castañeda-Cardona C, et al . Suicide in the Indigenous Population of Latin America: a systematic review. Rev Colomb Psiquiatr. 2017;46 (4):237-242. doi: 10.1016/j.rcp.2016.12.002
https://doi.org/10.1016/j.rcp.2016.12.00...
). The indigenous cosmological diversity, in general, explains life as an existential moment prior to what would be “true life” and death as a means by which the soul would abandon the body to live in a more appropriate place(4141 Galvão PVM, Silva HRS, Silva CMFP. Temporal distribution of suicide mortality: a systematic review. J Affective Dis. 2018;228:132-42. doi: 10.1016/j.jad.2017.12.008
https://doi.org/10.1016/j.jad.2017.12.00...
).

Among non-indigenous people, suicide mortality rates were more expressive in more populous municipalities, reinforcing the idea that conflicts resulting from urbanization and modern life can generate anxiety, social and family disorders, stress, intolerance and disenchantment, which can lead to social isolation arising from the difficulties in dealing with situations identified as impossible to solve(3636 Pereira MM. Representações de suicídio indígena no Amazonas: o que desencadeia a vontade de morrer? Diversitates Int J [Internet]. 2017 [cited 2019 Dec 17];09(1):03-26. Available from: http://www.diversitates.uff.br/index.php/1diversitates-uff1/article/view/176/110
http://www.diversitates.uff.br/index.php...
). Still, it is highlighted that this way of life inhibits the availability for the attentive and solidary look capable of identifying possible emotional changes and suicidal ideations(3939 Santos EGO, Oliveira YOMC, Azevedo UNA, Nunes ADS, Amador AE, Barbosa, IR. Análise espaço-temporal da mortalidade por suicídio em idosos no Brasil. Rev Bras Geriatr Gerontol. 2017;20(6):854-65. doi: 10.1590/1981-22562017020.170115
https://doi.org/10.1590/1981-22562017020...
-4040 Azuero AJ, Arreaza-Kaufman D, Coriat J, Tassinari S, Faria A, Castañeda-Cardona C, et al . Suicide in the Indigenous Population of Latin America: a systematic review. Rev Colomb Psiquiatr. 2017;46 (4):237-242. doi: 10.1016/j.rcp.2016.12.002
https://doi.org/10.1016/j.rcp.2016.12.00...
).

The increase in suicide cases in the municipality of Altamira, both in indigenous and non-indigenous people, can be attributed to the accelerated and intense process of change in the social, geographical, and economic environment installed in the territory since 2010, with the release of the license to install the Belo Monte hydroelectric plant. The announcing of investments in the southwestern region of Pará, as a result of the construction of the hydroelectric plant, boosted the not always successful migratory process in search of job opportunities, as well as to the increase in the local population, disordered land occupation, and increased violence. In addition, this undertaking reached indigenous lands, causing a reduction in territory, the need to relocate to other areas and a consequent compromise in the lifestyle of this population(4242 Simoni AT, Dagnino RS. Dinâmica demográfica da população indígena em áreas urbanas: o caso da cidade de Altamira, Pará. Rev Bras Est Pop. 2016;33(2)43-51. doi:10.20947/S0102-30982016a0020
https://doi.org/10.20947/S0102-30982016a...
).

Finally, the analysis revealed inequalities in suicide rates between the indigenous and non-indigenous population, denoting the need for specific actions to prevent this problem. The stratification of suicide throughout the state of Pará, according to the municipalities, allowed the knowledge of the magnitude of the problem in a regionalized way, contributing to plan specific and more effective public policies.

Study Limitations

The limitations of the study are related to the use of secondary data, therefore, subject to incompleteness and inaccuracies, capable of producing bias in the results. The database offered by the SSPHP did not include the distribution of stratified cases by age group, sex, and education by municipality, nor by indigenous ethnicity.

Contributions to the Area

For nursing, knowing the reality of individuals who commit suicide and the factors that lead to this outcome is extremely relevant, especially in more vulnerable groups such as the indigenous population. The qualified role of nursing in dealing with this disease that affects people regardless of race/color is a necessity, highlighting that acting in indigenous health requires an understanding of the health-disease process, in addition to knowledge and skills based on interculturality. The importance of deepening studies related to the social, cultural context, and way of life capable of resulting in the occurrence of suicide is emphasized, for the adoption of care measures and preventive practices, in addition to the implementation of public policies aimed at this problem. The training of health professionals to serve different ethnic groups is a necessity that must be prioritized within specific public policies.

CONCLUSION

The findings made it possible to identify the heterogeneity of suicide in the territory of Pará, as well as the indigenous group being the most vulnerable to the event. In this way, the reality installed in the territorial spaces that characterize people’s way of life shows a relationship with the dynamics of suicide and should be valued in the intervention policies and educational practices to promote life.

Public sector incursions into the social and environmental surroundings, especially those of an economic nature, must be carefully planned to minimize the impact and consequences on the lives of local residents and those who migrate in search of opportunities. Such measures are essential to reduce situations of exposure of individuals to factors that trigger stress, anguish, uncertainty, and even despair due to the non-realization of needs, plans, and dreams.

It is worth highlighting the cultural diversity of indigenous populations, which refers to different actions of ethnic appreciation, with the Unified Health System prioritizing actions that contemplate the specificities of life of each human group, culturally signified.

Furthermore, suicide involves factors of the most diverse orders, running through economic, social, cultural, environmental, and interpersonal issues, and must be treated in all its dimensions. In this sense, it is essential to establish institutional partnerships and intersectoral actions, combining efforts to face the problem and reduce its occurrence.
