ABSTRACT
OBJETIVE
To estimate risk and protection factors associated with suicide in Campinas, Brazil, in 2019.
METHODS
This is a populational case-control study analyzing 83 cases of suicide that occurred in 2019 in Campinas, a Brazilian city with about 1.2 million inhabitants. Controls were composed of 716 inhabitants. An adjusted multiple logistic regression was used. Cases and controls were the dichotomous response variables. Sociodemographic and behavioral variables were the predictor variables.
RESULTS
The categories which presented higher risk of suicide were: males [OR = 5.26 (p < 0.001)]; people aged 10–29 years [OR = 5.88 (p = 0.002)]; individuals without paid work [OR = 3.06 (p = 0.013)]; individuals presenting problematic use of alcohol [OR = 33.12 (p < 0.001)] and cocaine [14.59 (p < 0.007)]; and people with disabilities [OR = 3.72 (p < 0.001)]. Moreover, the perception of fear was associated with reduced suicide risk [OR = 0.19 (p = 0.015)]. Higher district HDI levels also showed a 4% decrease in risk for each 0.01 increase in district HDI levels [OR = 0.02 (p = 0.008)].
CONCLUSIONS
This study evidenced the association between sociodemographic and behavioral variables and suicide. It also emphasized the complexity in the dynamics between personal, social, and economic factors to this external cause of death.

INTRODUCTION
Suicide is a major public health issue in Brazil and worldwide. According to the World Health Organization (WHO), suicide accounts for 800,000 deaths per year globally, with an unequal distribution between sexes, affecting three men for each women11.World Health Organization. World Health Statistics 2018: monitoring health for the SDGs Sustainable Development Goals. Geneva (CH): WHO; 2018 [cited 2020 Jul 1]. Available from: https://apps.who.int/iris/bitstream/handle/10665/272596/9789241565585-eng.pdf?ua=1
https://apps.who.int/iris/bitstream/hand...
. Suicides are also the second main cause of death in the population 15–29 years old. In 2016, the global age-standardized mortality rate for suicide was 11 cases per 100,000 individuals22.World Health Organization. Suicide in the world: global health estimates. Geneva (CH): WHO; 2019 [cited 2020 Aug 1]. Available from: https://apps.who.int/iris/handle/10665/326948
https://apps.who.int/iris/handle/10665/3...
. This ratio varied greatly, from three to 33 deaths per 100,000 individuals, affecting low-and-middle-income countries more22.World Health Organization. Suicide in the world: global health estimates. Geneva (CH): WHO; 2019 [cited 2020 Aug 1]. Available from: https://apps.who.int/iris/handle/10665/326948

. In Brazil, according to the official mortality database33.Ministério da Saúde (BR), Secretaria de Vigilância em Saúde. Sistema de Informações de Mortalidade -SIM. Brasília, DF: DATASUS; 2020. http://tabnet.datasus.gov.br/cgi/deftohtm.exe?sim/cnv/ext10uf.def
http://tabnet.datasus.gov.br/cgi/deftoht...
, the mortality rates for suicide totaled 6.1 deaths per 100,000 individuals in 201833.Ministério da Saúde (BR), Secretaria de Vigilância em Saúde. Sistema de Informações de Mortalidade -SIM. Brasília, DF: DATASUS; 2020. http://tabnet.datasus.gov.br/cgi/deftohtm.exe?sim/cnv/ext10uf.def
http://tabnet.datasus.gov.br/cgi/deftoht...
. The distribution between sexes followed the global trend, with a 9.7 mortality ratio per 100,000 males and 2.6 in 100,000 females.
Suicide is a preventable cause of death and multiple social and individual aspects influence this complex phenomenon44.Turecki PG, Brent DA. Suicide and suicidal behaviour. Lancet. 2016;387(10024):1227-39. https://doi.org/10.1016/S0140-6736(15)00234-2
https://doi.org/10.1016/S0140-6736(15)00...
. Causes for people to consider and commit suicide include gender-based violence, history of childhood violence, physical, financial, and psychological violence, feelings of guilt and failure, helplessness, hopelessness, incapacity of asking for help, social isolation, lack of autonomy, functional dependency, visual deficiencies, terminal illness, depression, anxiety, suicidal ideation, psychiatric disorders, and substance abuse55.Corona Miranda B, Hernández Sánchez M, García Pérez RM. Mortalidad por suicidio, factores de riesgos y protectores. Rev Haban Cien Med. 2016;15(1):90-100. , 66.Sousa GS, Perrelli JGA, Mangueira SO, Lopes MVO, Sougey EB. Clinical validation of the nursing diagnosis risk for suicide in the older adults. Arch Psychiatr Nurs. 2020;34(2):21-8. https://doi.org/10.1016/j.apnu.2020.01.003
https://doi.org/10.1016/j.apnu.2020.01.0...
.
Further understanding factors that influence suicide can provide important information to public authorities, health professionals, and society as a whole. Based on these factors, policies and actions can be developed to promote preventive measures against suicide. This study thus aims to investigate some of the risk and protective factors related to suicide in a large urban center in Brazil, increasing understanding of this phenomenon.
METHODS
This is a population-based case-control study conducted in Campinas, a city located about 96 kilometers from São Paulo, the capital city of the state of São Paulo. In 2019, Campinas had around 1,167,192 inhabitants77.Fundação SEADE. Sistema SEADE de Projeções Populacionais. São Paulo: SEADE; 2020 [cited j2020 Jun 1]. Available from: https://produtos.seade.gov.br/produtos/projpop/index.php
https://produtos.seade.gov.br/produtos/p...
, being the 3rd most populous city in the state of São Paulo and 14th most populous in Brazil. Campinas is a metropolis and the main city of the Metropolitan Region of Campinas, in Southeast Brazil. It constitutes an industrial and technological pole with a high human development index (HDI) (0.805), which reflects the non-pacific coexistence between wealth and poorness in large Brazilian cities which had a Gini Index of 0.56 in 201088.Pinto, D. G. C., Costa, M. A. C., Marques, M. L. D. A. C. (2013). O índice de desenvolvimento humano municipal brasileiro.. This article is part of a broader research investigation, which analyzed the risk factors of all deaths from violent causes in 201999.Cordeiro R, organizador. Morte matada. Curitiba, PR: Editora Appris; 2022..
Case Sampling
The Campinas Health Department receives, from multiple sources, the totality of Death Certificates under the city’s jurisdiction. These certificates are revised and classified according to the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10)1010.Organização Mundial da Saúde. Classificação Estatística Internacional de Doenças e Problemas Relacionados à Saúde. 10. ed. São Paulo: Edusp; 2000..
In a research partnership with the local Health Department, our study group received a database containing the information in the Death Certificates of all inhabitants of Campinas who died of external causes of death (Chapter XX in ICD-10) in any part of the national territory between January 1st 2019 and December 31st 2019.
From the information obtained in the Death Certificates, one of the group’s researchers contacted the family of the deceased. The research explained the aims of the research and presented an informed consent form to a member of the household (family or close relationship over 18 years old). If they accepted to participate, they were asked to sign the informed consent and underwent a structured interview. The interview was designed to obtain information (described below) about the deceased and to understand the circumstances of the death, using the method called Verbal Autopsy1111.World Health Organization. (2007). Verbal autopsy standards: ascertaining and attributing causes of death. Geneva (CH): WHO; 2007.. This study considers all those who died of suicide (X60.0 and X84.9 from the ICD-10) in 2019 in Campinas and whose families or close relationships agreed to participate.
Control Sampling
As the case sampling method, controls were selected considering the population of Campinas. A sample of 800 random addresses from households in Campinas was obtained by a partnership protocol with Campinas’ Water Supply and Sanitation Society, which covers 99.81% of households.
Before the in loco application of the survey (described on Data Collection), all participants received an explanatory letter describing the research and an informed consent form. The interviewer then visited the households and explained the purpose of the visit. One out of the over-10-years-old dwellers were drawn. The aims of the research were once more explained to the drawn over-10-years-old dweller. The survey was applied after participants signed the informed consent form. Refusals were excluded from the control sampling.
Data Collection
Data were collected from two sources. Some of the information was obtained from the Death Certificates whereas additional and complementary information was obtained by trained interviewers using a structured questionnaire. Participants classified as controls answered the same questionnaire as relatives of the deceased considering the previous 30 days. The data were gathered and classified as follows:
-
Sociodemographic variables: sex (male or female), age range (10 to 29, 30 to 49, 50 to 64, 65 or more), years of schooling, paid work (yes or no), form of employment (formal or informal).
-
Variables related to life events or behavioral aspects: fear of suffering violence by criminals and/or law enforcement personnel (yes or no); the presence of physical, visual, auditory, or intellectual disabilities (yes or no); use of alcohol, tobacco, marijuana, or cocaine (“do not use”, “recreational use”, “substance use disorder”); financial debt due to illicit drug purchase (yes or no); having suffered threats to one’s physical or mental integrity (yes or no).
Data gathered during the interviews were later associated with the municipal Human Development Index by Units. The Human Development Index by Units (HDIU) is a method which estimates HDI for smaller units within a metropolis according to socio-environmental characteristics1212.Martins CMR, Germano LRRGBN, Rangel RR. Metodologia das Unidades de Desenvolvimento Humano da Região Metropolitana de Porto Alegre. Indic Econ FEE. 2016;43(4):91-108.. In 2013, IPEA (Institute for Applied Economic Research) estimated HDIU for all metropolitan regions in Brazil1313.Instituto de Pesquisa Econômica Aplicada. Atlas da vulnerabilidade social nas regiões metropolitanas brasileiras. Brasília, DF: IPEA; 2015., reflecting more accurately sociodemographic disparities within larger political units. Similarly to the traditional HDI, HDIU is measured as a number between 0 (lower HDI) and 1 (higher HDI) and depicts economical, educational, and sanitary variables (income, schooling, and longevity)1414.United Nations. United Nations Development Programme. New York: UNDP; 2012 [cited 2020 Jul 1]. Available from: https://www.undp.org/
https://www.undp.org/...
. Campinas was divided into 187 Development Units in 2013. Its HDIU varied from 0.636 to 0.954.
Analysis
The data were analyzed according to the backward method1515.Lee KI, Koval JJ. Determination of the best significance level in forwarding stepwise logistic regression. Commun Stat Simul Comput. 1997;26(2):559-75. https://doi.org/10.1080/03610919708813397
https://doi.org/10.1080/0361091970881339...
. Univariate logistic regression models were initially adjusted, having each of the aforementioned variables as predictor variables and as a response to the individual’s status (case or control).
A multiple logistic regression model was then adjusted, having the sociodemographic variables as predictor variables and as a response to the individual’s status. As an entry criterion in the model, a p-value of ≤ 0.25 was adopted in the univariate analysis. To remain in the multiple models, a p-value of ≤ 0.05 was adopted.
The variables related to life events and behavioral aspects were then added to the model obtained in the previous step, using the same criteria.
Finally, in the final model, the variable HDIU was added to the adjustment obtained until then.
This research was submitted to the Research Ethics Committee of Faculdade de Ciências Médicas – Unicamp and accepted under the protocol 3.175.939, CAAE 04005118.9.0000.5404. All participants signed an informed consent form.
RESULTS
According to the Health Department of Campinas, 606 inhabitants died in 2019 due to external causes of death. Amongst these deaths, 86 were by suicide. Seven of those suicides were not included in this research either because the families couldn’t be reached or refused to participate. After conducting and interpreting the verbal autopsies, five of the 79 remaining suicides were re-classified as having another kind of external cause of death. In turn, verbal autopsy re-classified as suicide nine deaths previously classified as an external cause of death other than suicide (two assaults, one traffic accident, one death by immolation, one exogenous intoxication, one death by drowning, and three deaths of undetermined intent). This study thus considered 83 suicide cases in total.
Regarding controls, 29 of the 800 randomly drawn households were discarded for different reasons: refusal by the potential participant; absence of the potential participant; denied access by security personnel due to condominium security policies. Of the remaining 771 households, 55 were discarded due to age policy (only people over 10 years old were interviewed). The control group thus included 716 participants.
Table 1 shows the distribution of the sociodemographic variables and the variables related to life events and behavioral aspects evaluated by verbal autopsy both for cases and controls. Table 2 shows the statistical analysis obtained in the analysis of adjusted univariate logistic regression in step 1.
Table 3 synthesizes the statistical analysis obtained by the multivariable logistic regression in steps 3 and 4. Fear of suffering violence by criminals and/or law enforcement personnel as well as living in high HDI neighborhoods were identified as protective factors for suicide. Fearing suffering violence was associated with a 80% suicide risk reduction. Each 0.01 increase in HDI represented a suicide risk reduction of around 4%. Moreover, being under 65 years old, male, with no paid work, using alcohol, having cocaine use disorder, and having disabilities represented risk factors for suicide, though in different magnitudes.
As expected, the fourth and final step of the multivariable logistic regression analysis did not change the statistical significance of the variables evaluated in the previous steps.
DISCUSSION
Although in recent decades suicide has been acknowledged worldwide as one of the most important global challenges in public health, the Brazilian mitigation policy against suicide was launched only in 2019, under the Federal Law 13,819, of April 26. This legislation institutes the National Policy for the Prevention of Self-Mutilation and Suicide, which among other objectives, aims to develop control actions for the determinant and conditioning factors of this preventable cause of death. However, academic research on these control actions is still incipient. Investigating the sociodemographic factors, behavioral aspects, and life events related to suicide can thus provide valuable information to develop more effective public policies and preventive actions for this cause of death.
Regarding sociodemographic conditions, the significant outcome differences between sexes, age range, and paid work stand out. Men had a higher tendency of unfavorable outcomes, corroborating national and international scientific literature. In 2010, the suicide mortality rates in the state of São Paulo were 7.5 per 100,000 inhabitants in males and 4.6 in females1616.Bando DH, Lester D. An ecological study on suicide and homicide in Brazil. Cien Saude Colet. 2014;19(4):1179-89. https://doi.org/10.1590/1413-81232014194.00472013
https://doi.org/10.1590/1413-81232014194...
. This difference is also observed in the Brazilian population. In a recent report about suicide in adults, the Royal College of Psychiatrists (UK) showed that three out of four people who die of suicide are male. Furthermore, suicide was the major cause of death in males under 50 years old1717.Royal College of Psychiatrists. Self-harm and suicide in adults: final report of the Patient Safety Group. London (UK): 2020..
Regarding age range, suicides represent one of the most important causes of death in both absolute and relative values1818.World Health Organization. Preventing suicide: a global imperative. Geneva (CH): WHO; 2014.. In Brazil, the latest national epidemiological report on suicide and suicidal attempts1919.Ministério da Saúde (BR), Secretaria de Vigilância em Saúde. Perfil epidemiológico das tentativas e óbitos por suicídio no Brasil e a rede de atenção à saúde. Bol Epidemiol. 2017;48(30):1-15. show that, whilst the suicide mortality rate was 5.5 per 100,000 inhabitants nationwide, it reached 8.9 per 100,000 inhabitants amongst people over 80 years old. Nevertheless, in Campinas, our study showed that individuals under 29 years old have a higher risk of suicide, which follows a global tendency1818.World Health Organization. Preventing suicide: a global imperative. Geneva (CH): WHO; 2014.. Suicide represents 8.5% of the total causes of death in people between 15 and 29 years old and is the second main cause of death worldwide, behind only traffic accidents in the same age range1818.World Health Organization. Preventing suicide: a global imperative. Geneva (CH): WHO; 2014..
In our research, not having paid work also showed an unfavorable outcome, corroborating the international trend which indicates higher suicide risks associated with financial instability2020.Stuckler D, Basu S. The Body Economic: why austerity kills: recessions, budget battles, and the politics of life and death. New York: Basic Books; 2013.. According to a 2008 multicenter research conducted in 54 countries under economic crisis, losing one’s job, foreclosure, and financial uncertainty were considered risk factors for suicide, especially when associated with other individual risk factors such as depression, anxiety, exposure to violence, and harmful use of alcohol2121.Chang SS, Stuckler D, Yip P, Gunnell D. Impact of 2008 global economic crisis on suicide: time trend study in 54 countries. BMJ. 2013;347:f5239. https://doi.org/10.1136/bmj.f5239
https://doi.org/10.1136/bmj.f5239...
.
Importantly, the association between harmful use of alcohol and other psychoactive addictive drugs and suicide is also globally known1818.World Health Organization. Preventing suicide: a global imperative. Geneva (CH): WHO; 2014.. In this sense, our research also corroborates the international literature, showing higher risks of suicide amongst people who presented recreational and harmful use of alcohol and harmful use of cocaine. A literature review with results from ten countries found the use of alcohol and other addictive substances in 25 to 50% of those who died of suicide2222.Schneider B. Substance use disorders and risk for completed suicide. Arch Suicide Res. 2009;13(4):303-16. https://doi.org/10.1080/13811110903263191
https://doi.org/10.1080/1381111090326319...
.
Although other substances such as marijuana, heroin, and nicotine are also associated with higher suicide risk2323.Bohnert KM, Ilgen MA, McCarthy JF, Ignacio RV, Blow FC, Katz IR. Tobacco use disorder and the risk of suicide mortality. Addiction. 2014;109(1):155-62. https://doi.org/10.1111/add.12381
https://doi.org/10.1111/add.12381...
, our study found no statistical significance between marijuana and nicotine and suicide. In the social field, the results of our study also indicate an association between suicide and the presence of some physical/visual/auditive/intellectual disability, the HDIU of the HDI of where the cases lived, and the fear of suffering violence by criminals and/or police officers.
Having physical, visual, hearing, and cognitive disabilities were risk factors to suicide. A literature review showed triggers to suicide in people living with disabilities, such as frustration, lack of autonomy, lower sense of utility and dignity, and lower pleasure for life. In this sense, women require special attention since they frequently report refusing to overload others2424.Fässberg MM, Cheung G, Canetto SS, Erlangsen A, Lapierre S, Lindner R, et al. A systematic review of physical illness, functional disability, and suicidal behaviour among older adults. Aging Ment Health. 2016;20(2):166-94. https://doi.org/10.1080/13607863.2015.1083945
https://doi.org/10.1080/13607863.2015.10...
. Moreover, some studies also show an association between chronic pain and neurodevelopmental impairment and suicide2525.Stenager El, Stenager Eg. Somatic diseases and suicidal behaviour. Psychiatr Danub. 2006;18 Suppl 1:151..
Our study found that higher Human Development Indexes are a protective factor against suicide. In numbers, each 0.01 increase in HDI represented a 4% suicide risk reduction. Accordingly, lower income, unemployment, and poverty are risk factors for suicide globally2626.Bachmann S. Epidemiology of suicide and the psychiatric perspective. Int J Environ Res Public Health. 2018;15(7):1425. https://doi.org/10.3390/ijerph15071425
https://doi.org/10.3390/ijerph15071425...
. In Brazil, other researchers also show an inverse relationship between per capita income and suicide rates2727.Carvalho AC, Carvalho DF. Crecimiento y evolución económica-espacial de los suicidios en Brasil: Durkhein en la perspectiva de la econometría espacial. Málaga (ES): eumed.net; 2018 [cited 2020 Aug 1]. Available from: https://www.eumed.net/rev/oel/2018/08/durkhein-econometria-espacial.html
https://www.eumed.net/rev/oel/2018/08/du...
. Therefore, suicide must be increasingly understood as a public health, social, and economic problem.
One of the strengths of this study was the possibility of identifying how socioeconomic inequalities affect suicides. Since HDI considers health, educational, and economic conditions, this indicator reflects holistic analysis more accurately than pure economic indicators and better understands person-centered human development88.Pinto, D. G. C., Costa, M. A. C., Marques, M. L. D. A. C. (2013). O índice de desenvolvimento humano municipal brasileiro..
Although the scientific literature indicates violence as a risk factor for suicide2828.Kalt A, Hossain M, Kiss L, Zimmerman C. Asylum seekers, violence, and health: a systematic review of research in high-income host countries. Am J Public Health. 2013;103(3):e30-42. https://doi.org/10.2105/AJPH.2012.301136
https://doi.org/10.2105/AJPH.2012.301136...
, 2929.World Health Organization. Global and regional estimates of violence against women: prevalence and health effects of intimate partner violence and non-partner sexual violence. Geneva (CH): WHO: 2013. , our research found no significant statistical difference between suicide and those who suffered domestic violence nor those who suffered threats to their physical or mental integrity. In turn, fear of suffering violence by criminals and/or law enforcement personnel were positively associated with the outcome. Fear can therefore reflect a sense of life appreciation, as opposed to hopelessness, frequently associated with suicidal behavior and suicide3030.O’Connor RC, Nock MK. The psychology of suicidal behaviour. Lancet Psychiatry. 2014;1(1):73-85. https://doi.org/10.1016/S2215-0366(14)70222-6
https://doi.org/10.1016/S2215-0366(14)70...
, 3131.Ferreira Junior A. O comportamento suicida no Brasil e no mundo. Rev Bras Psicol. 2015;2(1):15-28. .
Furthermore, central wealthy territories, with higher HDIU levels, presented lower rates of violence both by criminals and by abusive action of law enforcement.
Importantly, suicide is a highly complex social phenomenon which cannot be explained by a single factor. As an example, though South Korea is one of the richest countries worldwide, with low inequality levels, it presents the second-highest suicide mortality rates globally, rising from 8.8 to 33.3 deaths per 100,000 inhabitants from 1990 to 20113131.Ferreira Junior A. O comportamento suicida no Brasil e no mundo. Rev Bras Psicol. 2015;2(1):15-28..
Overall, our research endorses WHO’s recommendations that to create effective preventive measures against suicide, joint collaborative strategies must include multiple sectors from different governmental and non-governmental levels1818.World Health Organization. Preventing suicide: a global imperative. Geneva (CH): WHO; 2014.. Therefore, a responsible broad dialogue, which involves society and media, must be encouraged. Surveillance strategies must also be reinforced, focusing on preventive policies related to mental health and psychoactive substances use.
Furthermore, health professionals’ capacitation to evaluate and treat mental health issues is essential to prevent suicide1818.World Health Organization. Preventing suicide: a global imperative. Geneva (CH): WHO; 2014.. Research indicates that several people who died by suicide contacted a primary health care institution within the last 30 days before passing away3232.Pearson A, Saini P, Da Cruz D, Miles C, While D, Swinson N, et al. Primary care contact prior to suicide in individuals with mental illness. Br J Gen Pract. 2009;59(568):825-32. https://doi.org/10.3399/bjgp09X472881
https://doi.org/10.3399/bjgp09X472881...
. In the UK, 28% of the individuals who committed suicide visited a mental health service the year of their death3333.The University of Manchester. National Confidential Inquiry into Suicide and Safety in Mental Health: annual report England, Northern Ireland. Manchester (UK); 2019 [cited 2020 Jun 1]. Available from: https://www.hqip.org.uk/wp-content/uploads/2019/12/Mental-Health-CORP-Report-2019-FINAL.pdf
https://www.hqip.org.uk/wp-content/uploa...
. This shows the importance of developing a net-like health structure to deal with mental health issues in all of its aspects.
During our research, nine of the deaths registered as having violent causes other than suicide were reclassified as suicides. This indicates an underreporting of 10.8% of suicides in Campinas in 2019. This corroborates the results of a systematic review that covered 31 studies conducted in North America, Europe, Asia, and Oceania3434.Tøllefsen IM, Hem E, Ekeberg Ø. The reliability of suicide statistics: a systematic review. BMC Psychiatry. 2012;12:9. https://doi.org/10.1186/1471-244X-12-9
https://doi.org/10.1186/1471-244X-12-9...
, showing that 52% of the reviewed articles indicated over 10% of suicide underreporting.
As a study limitation, information regarding risk factors exposition was gathered retrospectively, which could lead to memory biases3535.Oliveira MAP, Parente RCM. Estudos de coorte e de caso-controle na era da Medicina Baseada em Evidência. Braz J Video Surg. 2010;3(3):115-25.. To control memory bias, interviews were conducted preferably within 15 days after the death by trained interviewers with a standard questionnaire. One of the main gaps associated with memory bias was the lack of information concerning visits to health facilities. This information would allow understanding the importance of health services in suicide prevention. This subject thus requires further studies.
Another limitation of this study is that it associated cases and controls living in the same micro area of the city with the HDIU value of the area. Depending on the social heterogeneity within the area, this may have caused misclassification, a phenomenon known as ecological fallacy. In turn, the micro areas of analysis were built preserving similar socio-environmental characteristics, which minimizes this possibility.
CONCLUSION
Being male, aged between 10 to 29 years, without paid work, using alcohol, and presenting harmful use of cocaine were risk factors for suicide in this research. Furthermore, higher HDI levels and perception of fear had a statistically relevant protective association. These findings emphasize the multifactorial complex nature of suicide which shows that, besides individual clinical and psychological approaches, social and economic improvement policies are essential to prevent this cause of death.
