HIV / AIDS in a triple border region: subsidies for reflections on public policiesa a Article extracted from the master's thesis entitled: HIV / AIDS IN MATO GROSSO DO SUL: TREND ANALYSIS, SPATIAL DISTRIBUTION AND CASE SURVIVAL.

ABSTRACT

Objective

Analyze the trend of HIV/AIDS cases by sex and age in the twin cities of Mato Grosso do Sul.

Method

ecological study of historical series. The HIV/AIDS notification forms, from 2009 to 2018, made available by the Secretary of State for Health and analyzed according to descriptive statistics, polynomial regression and geospatialization of the cases were used.

Results

734 notifications were registered, 57.9% of them in men, and with a higher incidence in the biennium 2017-2018 in both sexes. The trend of growth of notifications shows a positive acceleration in twin cities (r2=0.91; p<0.001). The highest coefficients of determination were observed in women, in the age group 35 to 49 years (r2=0.98; p<0.001), and in men from 15 to 19 years (r2=0.96; p<0.002).

Conclusion

The results challenge professionals and managers in the fight against the HIV/AIDS pandemic, requiring continuous reflection on the strategies/public policies adopted so far, especially in the border region. Implications for the practice: the nurse professional, by knowing the profile of its population and the distribution of cases, is able to draw strategies capable of reaching the public effectively and efficiently.

RESUMO

Objetivo

analisar a tendência dos casos de HIV/Aids por sexo e faixa etária nas cidades gêmeas de Mato Grosso do Sul.

Método

estudo ecológico de série histórica. Foram utilizadas as fichas de notificação de HIV/Aids, do período de 2009 a 2018, disponibilizadas pela Secretaria de Estado de Saúde e analisadas segundo estatística descritiva, regressão polinomial e geoespacialização dos casos.

Resultados

foram registradas 734 notificações, sendo 57,9% em homens, e com maior incidência no biênio 2017-2018 em ambos os sexos. A tendência de crescimento das notificações apresenta-se com aceleração positiva nas cidades gêmeas (r2=0,91; p<0,001). Os maiores coeficientes de determinação foram observados em mulheres, na faixa etária de 35 a 49 anos (r2=0,98; p<0,001), e em homens de 15 a 19 anos (r2=0,96; p<0,002).

Conclusão

os resultados desafiam profissionais e gestores no combate à pandemia de HIV/Aids, carecendo de reflexões contínuas diante as estratégias/políticas públicas adotadas até o momento, em especial na região de fronteira. Implicações para a prática: o profissional enfermeiro, ao conhecer o perfil da sua população e a distribuição dos casos, consegue traçar estratégias capazes de atingir o público de forma eficaz e efetiva.

INTRODUCTION

Acquired Immunodeficiency Syndrome (AIDS), even after three decades of its emergence, still constitutes a major challenge for the health area worldwide, since in 2016, it ranked fourth in the causes of death.11 Alipour Z, Eskandari N, Mokhah S. Evaluation of knowledge and attitude of non-medical students about AIDS. J Holist Nurs Midwifery. [Internet]. 2016 [citado 2019 jun 22];26(79):10-20. Disponível em: https://www.sid.ir/en/journal/ViewPaper.aspx?ID=510635
https://www.sid.ir/en/journal/ViewPaper....
Estimates point to 37.9 million people living with the human immunodeficiency virus (HPV) in the world, with 27.3 million (61.47%) having access to antiretroviral treatment.22 Programa Conjunto das Nações Unidas sobre HIV/Aids. [Internet]. 90-90-90: uma meta ambiciosa de tratamento para contribuir para o fim da epidemia de aids. Genebra: UNAIDS; 2015 [citado 2019 jun 22]. 36 p.

In the national scenario, the mortality coefficient is 5.7/100 thousand inhabitants, with an increase in the North and Northeast regions and stable in the Center-West region.33 Guimarães MDC, Carneiro M, Abreu DMX, França EB. Mortalidade por HIV/Aids no Brasil, 2000-2015: motivos para preocupação? Rev Bras Epidemiol. 2017 maio;20(20, Suppl 1):182-90. http://dx.doi.org/10.1590/1980-5497201700050015. PMid:28658382.
http://dx.doi.org/10.1590/1980-549720170...
In addition, the disease remains concentrated in specific groups, such as injecting drug users, men who have sex with men and sex workers, whose prevalence is higher when compared to the general population in the 15-49 age group.44 Pereira GFM, Shimizu HE, Bermudez XP, Hamann EM. Epidemiologia do HIV e aids no estado do Rio Grande do Sul, 1980-2015. Epidemiol Serv saude. 2018 nov 8;27(4):e2017374. http://dx.doi.org/10.5123/s1679-49742018000400004.
http://dx.doi.org/10.5123/s1679-49742018...

Faced with this scenario, the importance of public health policies is highlighted, which based on the demands and needs evidenced over time, and based on the population's health profile, have favored the development of laws, programs and strategies that contribute to the development of care actions.55 Guimarães MDC, Magno L, Ceccato MDGB, Gomes RRFM, Leal AF, Knauth DR et al. HIV/AIDS knowledge among MSM in Brazil: a challenge for public policies. Rev Bras Epidemiol. 2019;22(Suppl 1):e190005. http://dx.doi.org/10.1590/1980-549720190005.supl.1. PMid:31576981.
http://dx.doi.org/10.1590/1980-549720190...

With this in mind, in 2015 the Ministry of Health adhered to the goal 90-90-90, which proposes that 90% of the population is aware of their serological status, 90% of patients are in treatment and 90% of patients have undetectable viral load.22 Programa Conjunto das Nações Unidas sobre HIV/Aids. [Internet]. 90-90-90: uma meta ambiciosa de tratamento para contribuir para o fim da epidemia de aids. Genebra: UNAIDS; 2015 [citado 2019 jun 22]. 36 p.

However, some aspects related to the health and educational system have hindered the achievement of the proposed goal,66 Loch AP, Nemes MIB, Santos MA, Alves AM, Melchior R, Basso CR et al. Avaliação dos serviços ambulatoriais de assistência a pessoas vivendo com HIV no sistema único de saúde: estudo comparativo 2007/2010. Cad Saude Publica. 2018;34(2):e00047217. http://dx.doi.org/10.1590/0102-311x00047217. PMid:29489944.
http://dx.doi.org/10.1590/0102-311x00047...
especially concerning the structuring of the network of assistance to PLHIV and/or with AIDS, focusing on integral care.77 Melo EA, Maksud I, Agostini R. Cuidado, HIV/Aids e atenção primária no Brasil: desafio para a atenção no Sistema Único de Saúde? Rev Panam Salud Publica. 2018;42:e151. http://dx.doi.org/10.26633/RPSP.2018.151. PMid:31093179.
http://dx.doi.org/10.26633/RPSP.2018.151...
Thus, although health programs focus on strategic behavioral, biomedical and structural actions, there are gaps between the need, supply, adherence and retention to drug and non-drug treatment.88 Kharsany ABM, Karim QA. HIV infection and AIDS in sub-saharan africa: current status, challenges and opportunities. Open AIDS J. 2016;10:34-48. http://dx.doi.org/10.2174/1874613601610010034. PMid:27347270.
http://dx.doi.org/10.2174/18746136016100...

Furthermore, territorial characteristics may influence the distribution, prevalence of cases and access to health services, especially in border regions, where twin cities are located - those with close political, socio-cultural and economic interaction, although located in distinct countries99 Brito AR, Missio FJ. Planejamento territorial em cidades gêmeas. Rev. Bra. G&DR. [Internet]. 2019; [citado 2020 out 24];15(6):52-63. Disponível em: https://rbgdr.net/revista/index.php/rbgdr/article/view/5184/842
https://rbgdr.net/revista/index.php/rbgd...
, which elucidates the need for differentiated attention, especially with regard to access to health services.1010 Campos HA. The strategic role of twin cities in controlling goods in border regions in the MERCOSUR context: Uruguaiana (BR) and Paso de los Libres (AR). Redes (Bernal). 2016 dez 31;22(1):56-73. http://dx.doi.org/10.17058/redes.v22i1.8667.
http://dx.doi.org/10.17058/redes.v22i1.8...

It should be noted that sometimes the interaction between peoples occurs due to the migration of the population to territory with better resources. Brazil, for example, when compared to Paraguay and Bolivia, presents a public health policy of universal access, which leads to the process of Pendular Migration.1111 Rodrigues-Júnior AL, Castilho EA. AIDS e doenças oportunistas transmissíveis na faixa de fronteira Brasileira. Rev Soc Bras Med Trop. 2010 set;43(5):542-7. http://dx.doi.org/10.1590/S0037-86822010000500014. PMid:21085866.

http://dx.doi.org/10.1590/0102-311x00182...
That is, individuals leave their city of residence/origin for another, in search of better conditions, either of access to health, work or education, returning in the same day or in a few days.1313 Zaslavsky R, Goulart BNG, Ziegelmann PK. Cross-border healthcare and prognosis of HIV infection in the triple border Brazil-Paraguay-Argentina. Cad Saude Publica. 2019;35(9):e00184918. http://dx.doi.org/10.1590/0102-311x00184918. PMid:31508700.
http://dx.doi.org/10.1590/0102-311x00184...

The Bolivian National Health System, for example, is not universally accessible, care actions are fragmented and citizens need to pay for care, whether in public or private establishments. Only pregnant women, the elderly and children up to five years old have free care.1414 Ferreira CMPG, Mariani MAP, Braticevic SI. As múltiplas fronteiras presentes no atendimento à saúde do estrangeiro em Corumbá, Brasil. Saude Soc. 2015;24(4):1137-50. http://dx.doi.org/10.1590/S0104-12902015137475.
http://dx.doi.org/10.1590/S0104-12902015...
In Paraguay, access to the public health system is only possible by those citizens who have a signed work permit.1515 Fabriz LA.

Due to the issues experienced in border regions, the countries integrating the Southern Common Market (MERCOSUR) have entered into bilateral agreements to combat and control aggravations, influenced by social inequality, in order to promote a healthy interaction between nations. In this sense, the International Cooperation Program for HIV/AIDS Prevention and Control has established specific strategies to increase access to antiretroviral therapy in border regions,1616 Ribeiro AA, de Oliveira Lupatini E, dos Santos DG. International cooperation: drugs donated by the Brazilian government, 2005-2016. Rev Panam Salud Publica. 2018;42:1-8. http://dx.doi.org/10.26633/RPSP.2018.67.

because there is greater vulnerability to HIV infection in immigrant populations when compared to the local population, either due to difficulties in access to health services, xenophobia1818 Silvestre E, Weiner R, Hutchinson P.

In a study carried out at the border between Brazil, Argentina and Paraguay, the authors found an increasing incidence coefficient of reported cases of HIV/AIDS from 1988 to 2012, with higher prevalence of sexual transmission among heterosexuals, followed by injecting drug users.2121 Mombelli MA, Barreto MS, Arruda GO, Marcon SS. Epidemia da aids em tríplice fronteira: subsídios para a atuação profissional. Rev Bras Enferm. 2015 maio/jun;68(3):429-37. http://dx.doi.org/10.1590/0034-7167.2015680308i. PMid:26312513.
http://dx.doi.org/10.1590/0034-7167.2015...
By considering the peculiar characteristics of this region - the intense drug traffic and the free access of the foreign population to the Brazilian health service - the authors affirmed the need to modify the confrontation of the epidemic in border regions,2121 Mombelli MA, Barreto MS, Arruda GO, Marcon SS. Epidemia da aids em tríplice fronteira: subsídios para a atuação profissional. Rev Bras Enferm. 2015 maio/jun;68(3):429-37. http://dx.doi.org/10.1590/0034-7167.2015680308i. PMid:26312513.
http://dx.doi.org/10.1590/0034-7167.2015...
which justifies studies in this area. It is worth mentioning that there are already studies pointing out the main characteristics of the region and the population of the triple border between Brazil, Paraguay and Argentina in the state of Paraná,2121 Mombelli MA, Barreto MS, Arruda GO, Marcon SS. Epidemia da aids em tríplice fronteira: subsídios para a atuação profissional. Rev Bras Enferm. 2015 maio/jun;68(3):429-37. http://dx.doi.org/10.1590/0034-7167.2015680308i. PMid:26312513.

http://dx.doi.org/10.1590/1981-7746-sol0...
but the border region between Brazil, Paraguay and Bolivia in the state of Mato Grosso do Sul (MS) still lacks such studies. Thus, the following question arises: What is the behavior of the HIV/AIDS pandemic in the triple border region in the state of Mato Grosso do Sul (MS)?

It is important to emphasize that the continuous vigilance over the tendency of diseases in a certain region can subsidize the reorganization of the services offered, in order to attend the local specificities, through the development of actions that facilitate the access to health services and the implementation of the own actions of care.

In view of the above, this study aims to analyze the trend of HIV/AIDS cases by sex and age group in the twin cities of MS.

METHOD

Ecological study of historical series, which analyzed the trend of reported cases of HIV/AIDS in individuals from ten years of age and up, in twin cities located in the state of Mato Grosso do Sul, from 2009 to 2018. The period was determined in order to carry out a time cut of the last ten years.

This state has seven twin cities: Bela Vista, Corumbá, Coronel Sapucaia, Mundo Novo, Paranhos, Porto Murtinho and Ponta Porã. Data from the last census show an estimated population of 249,521 individuals residing in these cities.2323 Instituto Brasileiro de Geografia e Estatística. Censo 2010 [Internet].

Corumbá borders Puerto Quijarro in Bolivia and the other municipalities have Paraguay as their neighbor. These cities have an interaction called synapse, which favors the relationship between two or more countries, both economic and free access of foreigners to services offered on both side.1010 Campos HA.

After authorization from the State Secretariat and the Ethics in Research Committee, the database, containing the information related to HIV/AIDS notifications (except for identification of individuals), was sent electronically to the principal researcher in December 2019. The inclusion criterion was the notification in one of the seven twin cities, and those that presented duplicates would be counted only once.

The variables analyzed were: age, gender, exposure category, education and gross incidence coefficient. The following age groups were adopted: “10-14”, “15-19”, “20-34”, “35-49”, “50-64” and “≥65” years. This division was chosen because the under-19 age group shows a growing trend, especially the 15-19 age group,2626 Ministério da Saúde (BR). Boletim epidemiológico HIV/Aids. Brasília: Ministério da Saúde; 2018. which generates the need for further investigations. The other age groups were grouped every 15 years in order to make the analyses possible due to the distribution of the database. The incidence coefficients were obtained from the number of reported cases of HIV/AIDS in twin cities, by sex and age group, divided by the total population, expressed per 100,000 inhabitants. The 2010 Demographic Census data were used because the population estimates do not carry out the distribution by sex and age group.2323 Instituto Brasileiro de Geografia e Estatística. Censo 2010 [Internet]. Brasília: IBGE; 2019 [citado 2019 ago 22]. Disponível em: https://censo2010.ibge.gov.br/resultados.html
https://censo2010.ibge.gov.br/resultados...

The Statistical Package for the Social Sciences (SPSS) software version 23 was used for data analysis. The trend analysis was performed using the polynomial regression model considering the incidence rates as dependent variable (Y) and the years as independent variable (X), grouped by sex and age group. In order to avoid collinearity between the terms of the regression equation, the centralized variable was used, with the year 2013.5 being the midpoint. Dispersion diagrams were constructed between the incidence rate and the years in order to verify the function that expressed the relationship between them, and thus choose the polynomial order for the analysis, and the polynomial regression model. The coefficient of determination (r2) was used as a precision measure. The trend was considered significant when the estimated model obtained p<0.05.

In order to define the model to be used, the following order of tests was performed: simple linear regression (Y = β0 + β1X), and then the second degree models (Y = β0+ β1X + β2X22 Programa Conjunto das Nações Unidas sobre HIV/Aids.

). In this way, the one that obtained the best statistical significance, the highest measure of precision and residue without vices was chosen. When two models were similar for the same variable, from the statistical point of view, the simplest one was chosen, given the principle of parsimony. The series were smoothed by means of a moving average centered on three successive averages.

In order to verify the spatiality of the cases and possible changes in the place of notification in relation to the place of housing, geo-spatialization was carried out. For this, the software QGIS, version 2.18, was used to make the maps through the interpolation of metrics by code of the municipality of notification and code of the municipality of residence according to the shapefile of the state of MS provided by IBGE.2727 Instituto Brasileiro de Geografia.

The study was approved by the Permanent Committee on Ethics in Research with Human Beings of the Federal University of Mato Grosso do Sul, under the ordinance. 3.789.678.

RESULTS

In the period 2009 to 2018, 734 notifications of HIV/AIDS were registered in the twin cities. There were no duplicate notifications in the period. Of these, 425 (57.9%) were in males. Of the total notifications, 37 corresponded to individuals residing in Paraguay or Bolivia, without identification of the specific city, and one of them had no information about the place of residence.

In relation to the municipalities where the notification occurred there was the following behavior: Ponta Porã, with 354 (48.22%), followed by Corumbá, with 292 (39.78%), Mundo Novo, with 31 (4.22%), Bela Vista, with 25 (3.40%), Porto Murtinho, with 15 (2.04%), Coronel Sapucaia, with 13 (1.77%) and Paranhos, with four (0.54%).

The process of commuting migration is observed in the comparison between the maps, Figure 1 and Figure 2, whose population transition occurs between the neighboring municipalities, and between the neighboring countries, when identifying the places of residence. Over the years, it is possible to verify the behavior of notifications (Figure 1), and in 2009 cases of AIDS were notified in Corumbá and Ponta Porã, however, in the course of time there was the process of internalization, and in 2018, all cities had cases notified.

Figure 2 shows that the place of residence of the notified individuals shows a behavior similar to the chronology of the place of notification, with concentration in the Center-South region of the state and predominance of small municipalities, except Ponta Porã (medium size).

Until 2013, only AIDS cases were reported, and the accumulated incidence from 2009 to 2013 was 92.58 cases/100 thousand inhabitants. As of 2014, PLHIV were included in the notification, and the accumulated incidence from 2014 to 2018 was 201.59 cases/100 thousand inhabitants in twin cities.

During the study period, the heterosexual exposure category was more frequent, with 257 cases (35.01%) in females and 205 (27.92%) in males. The homosexual exposure category accumulated 105 (14.30%) cases. It should be noted that in 167 (22.75%) notifications the exposure category was not specified, being listed as ignored. It should be noted that in 167 (22.75%) notifications the exposure category was not specified, being listed as ignored. Table 1 shows the incidence coefficient distributed by gender and age group by biennium.

In the trend analysis, it was observed that the highest average coefficients of the period (β0) prevailed in individuals aged between 20 and 64 years for both sexes, with an increasing tendency and positive acceleration, with the exception of the female population aged between 50-64 years which remained stable. The highest annual increase in the incidence in the 15-19 age group for females is evident (β1) and 35-49 for men (β3). There was no decrease in cases in any age range, as shown in Table 2.

DISCUSSION

In this study, there was a total upward trend, with positive acceleration of HIV/AIDS cases in the border region over the years, with dispersion among municipalities, which elucidates the need for reflection on surveillance actions developed and the inclusion of particularities of each specific context, for example, in relation to the concentration of sex and age group. However, it is reiterated that the change in the notification criteria, as of 2014, may have influenced these results, since there was an increase in the cumulative incidence of cases.

The heterogeneity of health services available in South America contributes to the disparities in the assistance provided, which sometimes presents itself in a segregated manner, forcing some individuals to seek assistance in other localities. In the cases of Bolivia and Paraguay, the offer of the health system moves towards integral and universal care. In Brazil, the Unified Health System offers free assistance to any citizen, although it has different assistance characteristics in each region.2929 Giovanella L, Almeida PF. Atenção primária integral e sistemas segmentados de saúde na América do Sul. Cad Saude Publica. 2017;33(Suppl 2):e00118816. http://dx.doi.org/10.1590/0102-311x00118816. PMid:28977122.
http://dx.doi.org/10.1590/0102-311x00118...

The existence of the migratory process can lead to difficulties in identifying the population's characteristics, as well as the dissemination of different health problems. A study conducted in the border region of China from 2010 to 2014 identified a higher prevalence of Sexually Transmitted Infections (STIs) in immigrant sex workers from the neighboring country, Vietnam. He also pointed out that factors present in the region - drug trafficking, sexual exploitation, cheap labor and barriers to access to health services - may be associated with the prevalence of STIs.3030 Zhang C, Li X, Liu Y, Qiao S, Zhou Y, Tang Z et al. Human immunodeficiency virus, syphilis and hepatitis C virus prevalence trends among cross-border migrant Vietnamese female sex workers in Guangxi, China. BMC Public Health. 2015 dez 9;15:1223. http://dx.doi.org/10.1186/s12889-015-2561-0. PMid:27391948.
http://dx.doi.org/10.1186/s12889-015-256...

This reality is not far from the context of Mato Grosso do Sul, where the border region is marked by intense conflict due to drug trafficking, sex tourism, and economic difficulties of the municipalities. In a study conducted in the same region, the authors identified other neglected diseases linked to low socioeconomic conditions and barriers to access to health services, such as leprosy, in addition to the large flow of people seeking health services in the Brazilian territory.3131 Ajalla ME, Andrade SM, Tamaki EM, Waissmann W, Diettrich SH, Silva BA. The context of leprosy in Brazil-Paraguay border. Cien Saude Colet. 2016 jan;21(1):225-32. http://dx.doi.org/10.1590/1413-81232015211.20572014. PMid:26816179.
http://dx.doi.org/10.1590/1413-812320152...

It should be noted that the bilateral cooperation agreement1717 Fagundes HS, Nogueira VMR, Kreutz IT. Políticas de saúde no Mercosul: relevância e funcionalidade da dimensão jurídico-norativa. Argumentum. 2018 abr 28;10(1):150-65. http://dx.doi.org/10.18315/argumentum.v10i1.18745.
http://dx.doi.org/10.18315/argumentum.v1...
allows the access of individuals from neighboring countries to the Brazilian health system. In this context, professionals who assist this population need to recognize this demand and its specificities, in order to seek health education strategies, aiming at reducing cases of new infections.

However, some barriers may occur, such as language, culture, socioeconomic conditions and the immigrant's access to the Brazilian health system, through the use of illegal means - for example, the use of a fake address - or late search for the health service with a worsening of the health picture.3232 Nascimento VA, Andrade SMO. As armas dos fracos: estratégias, táticas e repercussões identitárias na dinâmica do acesso à saúde na fronteira Brasil/Paraguai. Horiz Antropol. 2018;24(50):181-214. http://dx.doi.org/10.1590/s0104-71832018000100007.
http://dx.doi.org/10.1590/s0104-71832018...
In view of this, the health professional, especially the nurse, who sometimes exercises leadership in front of the multi-professional team, needs to constantly reflect on the characteristics of the context in which he/she is inserted, in order to plan care actions that meet the specificities of the different territories and individuals.

The comparison between the maps showed the displacement of individuals, including within the national territory, because the notification did not always occur in the municipality of residence. This migration process may be associated with personal and health system infrastructure difficulties.1919 Wu F, Zhang A, Babbitt A, Ma Q, Eyal N, Pan X et al. Overcoming HIV stigma? A qualitative analysis of HIV cure research and stigma among men who have sex with men living with HIV. Arch Sex Behav. 2018 out 1;47(7):2061-9. http://dx.doi.org/10.1007/s10508-017-1062-x. PMid:29149399.
http://dx.doi.org/10.1007/s10508-017-106...
It should be noted that both aspects can directly and indirectly influence the link with the service and adherence to treatment. Therefore, the demand for assistance in other municipalities should not be restrained, but it is important that it be known by managers, because it interferes in the planning of assistance, health surveillance and actions to be developed.1111 Rodrigues-Júnior AL, Castilho EA. AIDS e doenças oportunistas transmissíveis na faixa de fronteira Brasileira. Rev Soc Bras Med Trop. 2010 set;43(5):542-7. http://dx.doi.org/10.1590/S0037-86822010000500014. PMid:21085866.
http://dx.doi.org/10.1590/S0037-86822010...

It is worth mentioning that small municipalities still have a stigmatized view regarding HIV infection. A study developed in the countryside of Paraíba, with individuals from rural areas, whose objective was to understand social representations in relation to AIDS, pointed out discriminatory and negative statements, and reports of non-use of condoms by most interviewees (474/789).3333 Furtado FM, Santos JA, Loredanna S, Araújo E, Saldanha AA, Silva J. 30 years later: social Representations about AIDS and sexual practices of rural towns residents. Rev Esc Enferm USP. 2016;50(Spec):74-80. http://dx.doi.org/10.1590/S0080-623420160000300011. PMid:27384279.
http://dx.doi.org/10.1590/S0080-62342016...
The way to face this kind of situation should occur still in childhood/adolescence through health education actions.

When observing the age range in the notifications, the cases of diagnosis in young people from ten to 14 years of age are highlighted, which although they present a stable tendency in both sexes, demonstrate early sexual initiation. At the national level, in the same age group, there were 211 notifications in the period of 2007-2018.2626 Ministério da Saúde (BR). Boletim epidemiológico HIV/Aids. Brasília: Ministério da Saúde; 2018. This occurrence was also observed in the border region between Brazil, Paraguay and Argentina, where sexual initiation occurred before the age of 14, mainly in males. It should be noted that, in this study, the young men reported not using condoms in all sexual relations, even though they received guidance about their importance.3434 Palma Priotto EMT, Führ AL, Gomes LMX, De Andrade Barbosa TL. Sexual initiation and contraceptive practices among adolescents in the tri-border area between Brazil, Argentina, and Paraguay. Rev Panam Salud Publica. 2018;42:1-9. http://dx.doi.org/10.26633/RPSP.2018.16.
http://dx.doi.org/10.26633/RPSP.2018.16...

The above mentioned fact deserves the attention of the scholars of this subject, because this behavior can have important reflexes in the present and future health of these young people. It is important to find strategies that reach these young people, who sometimes do not respond in the same way as adults. In this direction, a study conducted in Africa, for example, identified low adherence to condom use by the migrant population, but found that those who participated in educational actions about safe sexual practice, increased the chance of use by five times.1818 Silvestre E, Weiner R, Hutchinson P. Behavior change communication and mobile populations: The evaluation of a cross-border HIV/AIDS communication strategy amongst migrants from Swaziland. AIDS Care - Psychol Socio-Medical Asp AIDS/HIV. 2016 fev 1;28(2):214-20. http://dx.doi.org/10.1080/09540121.2015.1081668.
http://dx.doi.org/10.1080/09540121.2015....

In this context, the actions for the prevention of Sexually Transmitted Infections (STIs) developed by health professionals, in partnership with schools, through different approaches, constitute a protective factor for the early initiation of unsafe sexual activity,3535 de Moraes L, da Franca C, Silva B, Valença P, Menezes V, Colares V. Iniciação sexual precoce e fatores associados: uma revisão da literatura. Psicol Saude Doencas. 2019 mar 31;20(1):59-73. http://dx.doi.org/10.15309/19psd200105.
http://dx.doi.org/10.15309/19psd200105...
demonstrating the need to strengthen intersectoral actions (health - education) aimed at promoting safe sexual practices.3636 Amaral RS, Carvalho STRF, Silva RMAM, Dias RS. Soropositividade para HIV/AIDS e características sociocomportamentais em adolescentes e adultos jovens. Rev Pesq Saúde [Internet]. 2017 mai/ago; [citado 2019 ago 22];18(2):108-13. Disponível em: http://www.periodicoseletronicos.ufma.br/index.php/revistahuufma/article/view/8384/5209
http://www.periodicoseletronicos.ufma.br...

These approaches include the use of alternative methods of access and awareness of the population, whether through the use of social media or audiovisual resources, the identification of those with the greatest vulnerability and the provision of combined prevention measures, with the aim of the individual adhering to the one that best fits his/her life context. In the case of young people, there is a need for actions to stimulate the search for tests for early detection, because many believe it is unlikely to have HIV infection.3737 Clarke RD, Fernandez SB, Hospital M, Morris SL, Howard M, Wagner EF et al. Getting their feet in the door: communication cues to action for HIV testing and condom use behaviors among hispanic/latinx college students. J Prim Prev. 2020. http://dx.doi.org/10.1007/s10935-020-00610-3. PMid:33033906.
http://dx.doi.org/10.1007/s10935-020-006...
In addition, the behavior of the population in this age group, besides increasing the risks for STI, also increases the chances of occurrence of other public health problems - unwanted pregnancy and unsafe induced abortion.3838 Dulli L, Field S, Masaba R, Ndiritu J. Addressing broader reproductive health needs of female sex workers through integrated family planning/ HIV prevention services: a non-randomized trial of a health-services intervention designed to improve uptake of family planning services in Kenya. PLoS One. 2019;14(7):e0219813. http://dx.doi.org/10.1371/journal.pone.0219813. PMid:31339919.
http://dx.doi.org/10.1371/journal.pone.0...

In turn, the population between 15 and 19 years of age also deserves to be highlighted, as the temporal trend of HIV/AIDS infection in this region has been growing for both sexes. In the national scenario, for the population of this age group, in 2007-2018, there were 8,813 notifications, with significant reduction between 2017 and 2018, ranging from 1,724 to 653 notifications.2626 Ministério da Saúde (BR). Boletim epidemiológico HIV/Aids. Brasília: Ministério da Saúde; 2018. It should be noted that continuous surveillance of cases in border regions can contribute to access to diagnosis and especially treatment, which directly influences the maintenance of undetectable viral load and positive impact on quality of life.3939 Dantas CC, Dantas FC, Monteiro BAC, Leite LJ. Perfil epidemiológico dos pacientes com HIV atendidos em um centro de saúde da região litorânea do estado de Rio de Janeiro, Brasil, 2010-2011. Arq catarinenses Med. [Internet]. 2017 [citado 2019 ago 22];46(2):22-33. Disponível em: http://www.acm.org.br/acm/seer/index.php/arquivos/article/view/250/137
http://www.acm.org.br/acm/seer/index.php...

Regarding the behavior of the notifications, the results of the present study corroborate the research also carried out in a border region, which pointed out the predominance of HIV cases in heterosexuals.1414 Ferreira CMPG, Mariani MAP, Braticevic SI. As múltiplas fronteiras presentes no atendimento à saúde do estrangeiro em Corumbá, Brasil. Saude Soc. 2015;24(4):1137-50. http://dx.doi.org/10.1590/S0104-12902015137475.
http://dx.doi.org/10.1590/S0104-12902015...
In addition, the largest contingent of cases is among males (homosexual and heterosexual), which may be associated with the existence of multiple sexual partnerships and non-use of condoms, in addition to the absence and/or disability in the search for health services.2020 Poon CM, Wong NS, Kwan TH, Wong HTH, Chan KCW, Lee SS. Changes of sexual risk behaviors and sexual connections among HIV-positive men who have sex with men along their HIV care continuum. PLoS One. 2018;13(12):1-15. http://dx.doi.org/10.1371/journal.pone.0209008. PMid:30540851.
http://dx.doi.org/10.1371/journal.pone.0...
Thus, the greatest annual increase observed in the 35-49 age group in men highlights particularities in the active search for both preventive and early detection actions.

The growing trend and the higher average coefficients in the 20 to 64 age group reiterate HIV/AIDS as a public health problem. The identification of a rising profile among women demonstrates the feminization of HIV, however, this increase may be associated with higher demand for health services, and also the higher occurrence of pregnancy in the 20 to 40 age group.4040 Mesenburg MA, Wehrmeister FC, Silveira MFD. Teste de HIV solicitado e espontâneo: um estudo de base populacional com mulheres de uma cidade do Sul do Brasil. Cad Saude Publica. 2017;33(10):e00074415. http://dx.doi.org/10.1590/0102-311x00074415. PMid:29091172.
http://dx.doi.org/10.1590/0102-311x00074...

It is also worth considering that the adult and elderly population sometimes presents a higher prevalence of chronic comorbidities not related to HIV/AIDS infection, which leads to higher rates of early mortality.4141 Croxford S, Kitching A, Desai S, Kall M, Edelstein M, Skingsley A et al. Mortality and causes of death in people diagnosed with HIV in the era of highly active antiretroviral therapy compared with the general population: an analysis of a national observational cohort. Lancet Public Health. 2017;2(1):e35-46. http://dx.doi.org/10.1016/S2468-2667(16)30020-2. PMid:29249478.
http://dx.doi.org/10.1016/S2468-2667(16)...
In this sense, the importance of an additional characterization of the epidemiology of chronic diseases among the adult and elderly population living with HIV/AIDS is highlighted, in order to optimize clinical care and plan effective strategies for screening.

It is emphasized that the modification of this scenario goes beyond the direct action of health professionals and crosses the levels of municipal, state and federal management. Bilateral cooperation agreements may constitute better ways to reconcile care for the population of different countries.4242 Hortelan MS, Almeida ML, Fumincelli L, Zilly A, Nihei OK, Peres AM et al. Papel do gestor de saúde pública em região de fronteira: scoping review. Acta Paul Enferm. 2019;32(2):229-36. http://dx.doi.org/10.1590/1982-0194201900031.
http://dx.doi.org/10.1590/1982-019420190...
Professionals, through health education activities developed in partnership with entities and local representations, can expand the strategies of care and access to services.

Regarding the limitations of this study, it is important to point out the incompleteness in the completion of some data in the notification form, such as place of residence, schooling and exposure category. However, the importance of the results found should be emphasized, as they can provide reflections from existing public policies and direct care actions that meet the specificities of border regions. It is important to highlight the need for future studies to elucidate the profile of notifications in the state and allow for comparisons with border regions.

CONCLUSION AND IMPLICATIONS FOR THE PRACTICE

The total trend of HIV/AIDS cases, by sex and age group, in a triple border region was increasing. The results challenge health professionals and managers to fight the HIV/AIDS pandemic, requiring continuous reflection on the strategies/public policies adopted so far, especially in the border region.

The need for occupation of different social spaces by nursing professionals is highlighted, aiming at the dissemination of epidemiological surveys like this one, in order to subsidize actions and strategies to confront.

Thus, it is expected that the results may guide ways of acting in specific groups, and stimulate new studies that address the behavior of individuals in the border region, the access to health services by the foreign population, the perspectives of health professionals in the region and the impacts on Brazilian health.
