Análise espaçotemporal das internações por sífilis e HIV/aids nas Regiões de Saúde da Bahia / Spatiotemporal analysis of hospitalizations due to syphilis and HIV/aids in the Health Regions of Bahia / Análisis espaciotemporal de las hospitalizaciones por sífilis y VIH/sida en las Regiones de Salud de Bahía

A sífilis e a infecção causada pelo vírus HIV constituem importantes problemas de saúde pública, em razão das altas taxas de morbimortalidade e do impacto que causam aos programas e às políticas públicas de saúde, tanto de forma isolada quanto no caso de coinfecção. Mesmo a sífilis sendo uma doença curável, e o HIV/aids uma doença que possui tratamento, ambas têm atingido milhões de pessoas no mundo, inclusive no Brasil, onde o estado da Bahia se destaca pelos elevados índices de infecção. Esse quadro se intensifica quando se observam as notificações conforme a raça/cor da pele, havendo um grande número de casos entre jovens negros. Esta dissertação pretende analisar a dinâmica espaçotemporal das taxas de internação por sífilis e HIV/aids em adultos, nas Regiões de Saúde da Bahia, no período de 2000 a 2020. Os dados são provenientes do Sistema de Informações Hospitalares (SIH), disponibilizado pelo Departamento de Informática do Sistema Único de Saúde (DATASUS), enquanto os dados populacionais e de raça/cor da pele são do Instituto Brasileiro de Geografia e Estatística (IBGE). As análises envolveram tanto medidas descritivas quanto tendência temporal, autocorrelação e correlação cruzada. Nesse ínterim, foram utilizados o método detrended fluctuation analysis (DFA), para caracterizar a autocorrelação e identificar a persistência na série temporal; o coeficiente de correlação cruzada ρDCCA, para mensurar a correlação cruzada entre as séries; e a média móvel, para caracterizar a tendência. Também foi realizada a análise descritiva, com a estimativa da tendência temporal por meio do modelo de regressão linear, com correção de Prais-Winsten. No período de 2000 a 2020, foram registradas 16.454 internações, sendo 3,2% por sífilis e 96,8% por HIV/aids. Quanto ao estudo de base temporal, foi identificado um comportamento persistente (αDFA > 0,50) e uma correlação negativa fraca (< 0,20) tanto entre as taxas de sífilis quanto entre as de HIV/aids, sendo estatisticamente significante somente a autocorrelação da sífilis. Os jovens negros constituíram a maioria dos sujeitos hospitalizados, com média geral de idade de 39,2 anos, prevalência do sexo feminino para sífilis (60,5%) e do sexo masculino para HIV/aids (61,8%). As maiores taxas de sífilis foram encontradas nas regiões de saúde de Itabuna, Ilhéus, Paulo Afonso e Salvador. O comportamento da sífilis foi estatisticamente significante (p < 0,05), com variação percentual anual (VPA) de 14,1% (ß1 > 0 e p < 0,05), o que denota uma tendência crescente. Para os casos de HIV/aids, as maiores taxas foram observadas nas regiões de Salvador, Camaçari, Teixeira de Freitas e Seabra. Não houve significância estatística para HIV/aids (p > 0,05), sendo o VPA de 1,6% (ß1 > 0 e p < 0,05), o que também indica uma tendência crescente. Espera-se que, com esta pesquisa, seja possível contribuir não somente para a atualização do conhecimento sobre infecção por sífilis e HIV/aids em adultos, mas principalmente para a construção de indicadores e para o planejamento e fortalecimento das políticas públicas de saúde, com ênfase nos sistemas de vigilância do estado da Bahia.

Syphilis and the infection by the HIV virus are important public health problems, due to the high rates of morbidity and mortality and the impact they cause to public health programs and policies, both in isolation and in cases of co-infection. Even though syphilis is a curable disease, and HIV/AIDS is a disease that has treatment, both have reached millions of people around the world, including Brazil, where the state of Bahia stands out for its high infection rates. This picture is intensified when the notifications according to race/skin color are observed, since there is a large number of cases among young black people. This dissertation intends to analyze the spatiotemporal dynamics of hospitalization rates for syphilis and HIV/AIDS in adults, in the Health Regions of Bahia, from 2000 to 2020. The data came from the Hospital Information System (SIH), made available by the Department of Informatics of the Unified Health System (DATASUS), and the population and race/skin color data came from the Brazilian Institute of Geography and Statistics (IBGE). Analyzes involved both descriptive measures and temporal trend, autocorrelation, and cross-correlation. In the meantime, the detrended fluctuation analysis (DFA) method was used to characterize this autocorrelation and identify the persistence in the time series; the cross-correlation coefficient ρDCCA, to measure the cross-correlation between the series; and the moving average, to characterize the trend. Descriptive analysis was also performed, with the estimation of the temporal trend by the linear regression model, with Prais-Winsten (PW) correction. In the period from 2000 to 2020, 16,454 hospitalizations were registered, with 3.2% for syphilis and 96.8% for HIV/AIDS. Regarding the time-based study, a persistent behavior (αDFA > 0.50) and a weak negative correlation (< 0.20) were identified between both the syphilis and the HIV/AIDS rates, and only the autocorrelation for syphilis was statistically significant. Young black people constituted most hospitalized subjects, with a general mean age of 39.2 years, with a female prevalence for syphilis (60.5%) and a male for HIV/AIDS (61.8%). The highest rates of syphilis were found in the health regions of Itabuna, Ilhéus, Paulo Afonso, and Salvador. The behavior of syphilis was statistically significant (p-value < 0.05), with an average annual percent change (AAPC) of 14.1% (ß1 > 0 and p-value < 0.05), which denotes an increasing trend. For HIV/AIDS cases, the highest rates were observed in the regions of Salvador, Camaçari, Teixeira de Freitas, and Seabra. There was no statistical significance for HIV/AIDS (p-value > 0.05), with an AAPC of 1.6% (ß1 > 0 and p-value < 0.05), which also indicates an increasing trend. We hope that, with this research, it will be possible to contribute not only to the updating of knowledge about syphilis and HIV/AIDS infection in adults, but mainly to constructing indicators, and planning and strengthening public health policies, with an emphasis on surveillance systems of the state of Bahia.

La sífilis y la infección por el virus del VIH son importantes problemas de salud pública, dadas las altas tasas de morbimortalidad y el impacto que llevan a los programas y políticas de salud pública, tanto de forma aislada como en relación con la coinfección. Si bien la sífilis es una enfermedad curable y el VIH/sida, una enfermedad tratable, ambas han afectado a millones de personas en el mundo, y en Brasil destaca el estado de Bahía por sus altas tasas de infección. Este cuadro se intensifica aún más cuando se observan las notificaciones según raza/color de piel, en que hay un gran número de casos entre jóvenes negros. Esta tesis pretende analizar la dinámica espaciotemporal de las tasas de hospitalización por sífilis y VIH/sida en adultos, en las regiones de salud de Bahía (Brasil), en el período de 2000 a 2020. Los datos provienen del Sistema de Información Hospitalaria (SIH) que dispone el Departamento de Informática del Sistema Único de Salud (DATASUS); mientras que los datos de población y raza/color de piel se obtuvieron del Instituto Brasileño de Geografía y Estadística (IBGE). Los análisis incluyeron medidas descriptivas y tendencias temporales, autocorrelación y correlación cruzada. Por su parte, se realizó el método detrended fluctuation analysis (DFA) para caracterizar esta autocorrelación e identificar la persistencia en la serie temporal; el coeficiente de correlación cruzada ρDCCA para medir la correlación cruzada entre las series, así como la media móvil para caracterizar la tendencia. También se realizó un análisis descriptivo, con la estimación de la tendencia temporal mediante el modelo de regresión lineal, con corrección de Prais-Winsten (PW). De 2000 a 2020 se registraron 16.454 hospitalizaciones, el 3,2% por sífilis y el 96,8% por VIH/sida. En cuanto al estudio de base temporal, se identificó un comportamiento persistente (αDFA > 0,50) y una correlación negativa débil (< 0,20) tanto entre las tasas de sífilis como de VIH/sida, y solo es estadísticamente significativa la autocorrelación por sífilis. Los jóvenes negros son mayoría entre los individuos hospitalizados, cuyo promedio general de edad es de 39,8 años, con predominancia de mujeres con sífilis (60,5%) y de varones con VIH/sida (61,8%). Las mayores tasas de sífilis se encontraron en las regiones sanitarias de Itabuna, Ilhéus, Paulo Afonso y Salvador. El comportamiento de la sífilis fue estadísticamente significativo (p-valor < 0,05), con una variación porcentual anual (VPA) del 14,1% (ß1 > 0 y p-valor < 0,05), lo que apunta a una tendencia creciente. Para los casos de VIH/sida, las tasas más altas se observaron en las regiones de Salvador, Camaçari, Teixeira de Freitas y Seabra. No hubo significación estadística para el VIH/sida (p-valor > 0,05), con un VPA del 1,6% (ß1 > 0 y p-valor < 0,05), lo que también indica una tendencia creciente. Se espera que con esta investigación se pueda contribuir no solo a la actualización de conocimientos sobre la infección por sífilis y VIH/sida en adultos, sino principalmente a la construcción de indicadores, planificación y fortalecimiento de políticas públicas de salud, con énfasis en los sistemas de vigilancia en el estado de Bahía.

Analysis of intermunicipal journeys for cardiac surgery in Brazilian Unified Health System (SUS): an approach based on network theory.

INTRODUCTION: The transformation of data into information is important to support decision making and, thus, to induce improvements in healthcare services. The regionalized organization of healthcare systems is necessary to ensure the integrity of citizen care. From this perspective, the creation of mechanisms to guide and assess the behavior of a healthcare services network becomes necessary. However, these mechanisms must consider the interaction between different municipalities. The objective of this study is to apply network analysis as a supporting tool in the Brazilian Unified Health System (Sistema Único de Saúde-SUS) management. METHODS: The stages of the proposed method are described and applied in a real situation, analyzing the intermunicipal interaction network for cardiovascular surgery in the municipality of Vitória da Conquista, Bahia, Brazil, from 2008 to 2020. The metrics analyzed were journeys indices, flow of patients and distance of the journeys, considering the journeys from and to the municipality in focus. RESULT: There was an increase of the incoming flow and in-degree indices combined with a decrease in outgoing flow, showing the growing importance of this municipality as a provider of these services. CONCLUSION: The method used in the study has potential to be adopted as a management tool to assess the behavior of the interactions network of the selected service, aiding the regionalized organization of the healthcare system.

Bolsa Familia Program and Perinatal Outcomes: NISAMI Cohort.

This study aimed to assess the impact of the Bolsa Familia Program on perinatal outcomes of pregnant women. A cohort study was conducted with pregnant women supported by prenatal services at 17 Family Health Units in Bahia, Brazil. A previously tested structured questionnaire, which has sociodemographic, economic, prenatal care, lifestyle, and nutritional variables, has been used to collect data. The outcomes included premature birth and low birth weight. A hierarchical conceptual model was constructed, and logistic regression analysis was performed. From a total of 1173 pregnant women, the identified average age was 25.44 years and 34.10% had pre-gestational overweight. The non-beneficiary pregnant women presented a 1.54 (95% CI = 0.46-5.09) times higher chance of giving birth to children with low weight and a 1.03 (95% CI = 95% CI = 0.53-2.00) times chance of premature birth when compared to the beneficiary group. In the multilevel model, some variables were statistically significant, such as age between 18 and 24 years (p = 0.003), age greater than or equal to 35 years (p = 0.025), family income (p = 0.008), employment status (p = 0.010), and maternal height (p = 0.009). The Bolsa Familia Program, as an integrated strategy of social inclusion and economic development, is suggested to exert a protective effect on the health of mother-concept binomial.

Comparative Analysis of the Constitution and Implementation of Race/Skin Color Field in Health Information Systems: Brazil and South Africa.

The inclusion of race/skin color in Health Information Systems makes it possible to measure health inequities. Brazil and South Africa correspond to countries marked by profound inequalities, multiracial constituted that suffered from the historical process of colonization, and had racism legitimized as a structuring model of state development. The objective is to compare the information systems of Brazil and South Africa regarding the configuration and implementation of the item race/skin color. This is a qualitative, descriptive study, based on the content analysis proposed by Bardin. A survey on race/skin color was carried out in health department documents and ministerial sites in both countries. The collected material was processed and analyzed utilizing the IRAMUTEQ R software, version 0.7 alpha 2, with a test × 2 > 3.80 (p < 0.05), and by the TABNET application version 4.14 and Excel software, version 2016. In Brazil and Africa South, several health information systems did not include race/skin color. In both countries, health information systems were boosted in the mid-1990s. In Brazil, of the systems that provide data by race/skin color, the inclusion occurred after claims by the black movement. In South Africa, through the creation of the respective systems. The historical configuration of the question of race/skin color in both countries was guided by political and ideological references. In multiracial and unequal countries, race/skin color is a central political category to promote health equity.

Intersectionality of Race, Gender, and Common Mental Disorders in Northeastern Brazil.

This study applies the perspective of intersectionality, defined as social identities combining with one another and with structural societal factors to produce health inequities, to assess the interaction between race, gender, and common mental disorders (CMD) in northeastern Brazil. The Self-Reporting Questionnaire was used to assess CMD among a representative sample of adults in Feira de Santana, Bahia, Brazil (N=3273). Four groups (Black men, Black women, White women, White men) represented the intersection of race and gender. We used a Chi square test to compare the four groups and Poisson regressions to determine prevalence ratios (PR). White men had the lowest prevalence of CMD (11.1%) and Black women had the highest (37.2%). After adjusting for covariates, Black women had a statistically significantly higher prevalence of CMD than White men (PR=2.43; 95% CI: 1.39-4.25), though the prevalence among White women was not statistically significantly different from White men (PR=1.74; 95% CI: .93-3.30). Interaction tests were conducted on the multiplicative and additive scale, although the results were not statistically significant. These findings indicate that the experience of being both Black and a woman in Brazil is associated with elevated prevalence of CMD. Programs and interventions are needed to address this burden and research is needed to further explore its cause.

Screening for Structural Hemoglobin Variants in Bahia, Brazil.

Brazil was the country that received the largest number of Africans during the time of colonization, and Bahia was the Brazilian state that received the largest number of slaves from Africa. The purpose of this study was to evaluate the coverage of the newborn screening program for sickle cell disease in the Recôncavo Baiano region of the state of Bahia, and to show the frequency of the subjects with hemoglobin variants in the 2006-2009 period. Blood samples from neonates in twelve cities in the Recôncavo Baiano region were analyzed by High Performance Liquid Chromatography. A total of 16,402 children were born in this period, 14,773 of which underwent newborn screening. In this period 1416 children were born carrying hemoglobin variants HbS and HbC. Forty-seven patients--20 HbSS genotype and 27 HbSC genotype--were diagnosed in eleven of the twelve cities surveyed. The proportion of children born with sickle cell disease in the Recôncavo Baiano region was 1/314, which was higher than the 1/650 rate for the state of Bahia. The data presented in this study confirm the high frequency of sickle cell disease in Recôncavo Baiano, demonstrating the need to create a referral center for the care of patients with sickle cell diseases in the region.

[Inclusion of persons with disabilities in a Reference Center for STD / AIDS of a town in Bahia, Brazil]. / Inclusão da pessoa com deficiência em um Centro de Referência em DST/AIDS de um município baiano.

This qualitative study sought to ascertain the opinion of health professionals about the inclusion of people with disabilities in the activities of reception, prevention and treatment in a Reference Center for STD/AIDS. The data were submitted to Bardin's content analysis technique. The analysis showed that professionals conduct their service in the sense of inclusion, seeking ways of communication to reach these people as the use of LIBRAS, matching the physical structure, equality of attendance and understanding of the vulnerabilities of this population. Despite the great importance of strategies adopted in facilitating a friendly service to people with disabilities, those strategies leave mostly from isolated and individually activities. It is needed an effective link among the service managers and political actors in the construction and adaptation of materials, programs and public policies to achieve equitable and inclusion of this population.

Vigilância epidemiológica da violência e dos acidentes: experiência de um município do interior da Bahia / Epidemiological surveillance of violence and injuries: the experience of a municipality in Bahia / Vigilancia epidemiólogica de la violencia y de los accidentes: experiencia en un municipio del interior de la Bahia

Vigilância de Violências e Acidentes (VIVA) objetiva facilitar a coleta de dados e divulgação de informações sobre a violência e os acidentes, propor ações para a prevenção da violência, promoção da saúde e cultura de paz. Estudo exploratório de abordagem qualitativa que teve como objetivo descrever a experiência de implantação da VIVA no município de Feira de Santana (BA) e confrontar a experiência com as proposições políticas do Ministério da Saúde (MS). Participaram deste estudo, profissionais que trabalham em atividades técnicas e de gestão do programa. A coleta de dados ocorreu por meio de entrevista semiestruturada. O material empírico foi organizado de modo a possibilitar o relato da experiência, atendendo a uma sequência cronológica, confrontando-a com as proposições políticas sobre o tema, utilizando-se um suporte teórico apoiado em documentos oficiais que embasaram a discussão. Os resultados mostram que, a despeito de a política elaborada pelo MS para monitorar as violências e acidentes por causas externas que não geram óbitos e internações ser relevante e abrangente, a vontade política dos gestores é condição determinante para que a vigilância dessas ocorrências seja realmente realizada. Concluiu-se que o suporte financeiro e logístico inicial, disponibilizado pelo MS e pelas Secretarias Estaduais de Saúde, por meio das suas divisões de Vigilância Epidemiológica, certamente contribuiu significantemente para a criação do núcleo VIVA em Feira de Santana, mas não garantiu sua efetivação nos moldes definidos pelo MS. A participação dos movimentos sociais e o controle exercido pelas representações sociais no conselho municipal de saúde poderão reverter essa realidade.

Surveillance of Violence and Accidents (VIVA) aims to facilitate data collection and dissemination of information about violence and accidents, as well as propose actions to prevent violence, promote health and peace. This is a qualitative exploratory study that aimed to describe the experience of implementing the VIVA in Feira de Santana (BA), Brazil, and confront the experience with the policy proposals of the Ministry of Health. The study comprised of professionals working in technical activities and program management. The data were collected through semi-structured interview. The empirical material was organized to enable the reporting of experience serving a chronological sequence, comparing it with the policy proposals on the subject, using a theoretical framework supported by official documents that support the discussion. The results show that despite the policy prepared by the Ministry of Health to monitor the violence and accidents by external causes that do not generate hospitalizations and deaths, being relevant and comprehensive, political will of managers is a determinant aspect for the supervision of these occurrences. The initial financial and logistical support provided by the Ministry of Health and State Health Departments, through its surveillance divisions certainly contributed significantly to the creation of VIVA in Feira de Santana, but did not guarantee its effectiveness in a manner established by The Ministry of health. The participation of social movements and the control exerted by social representations in municipal health council may reverse this reality.

La Vigilancia de Violencias y Accidentes (VIVA) objetiva facilitar la recolecta y difusión de informaciones sobre la violencia y los accidentes, proponer acciones para la prevención de la violencia y promover la salud y la cultura de la paz. Estudio exploratorio de enfoque cualitativo que tuvo como objetivo describir la experiencia de la implementación de la VIVA en el municipio de Feira de Santana (BA) y confrontar la experiencia con las propuestas políticas del Ministerio de Salud (MS). Participaron de este estudio profesionales que trabajan en actividades técnicas y en la gestión del programa. Los datos fueron recolectados a través de entrevistas semiestructuradas. El material empírico fue organizado para permitir el relato de experiencia atendiendo a una secuencia cronológica, confrontándolas con las propuestas políticas sobre el tema, utilizando una base teórica apoyada en documentos oficiales que respaldan la discusión. Los resultados muestran que a pesar de la política elaborada por el Ministerio de Salud para el monitoreo de la violencia y los accidentes provocados por causas externas, los cuales no generan hospitalizaciones y muertes, es relevante e extenso, la voluntad política de los gestores es condición determinante para que la vigilancia de esas ocurrencias sea efectivamente realzada. Se concluye que el apoyo financiero y logístico inicial proporcionada por el Ministerio de Salud y las Secretarias Estaduales de Salud, a través de su división de Vigilancia epidemiológica, sin duda contribuyó significativamente para la creación del núcleo VIVA en Feira de Santana, pero sin garantizar su eficacia dentro de las pautas definidas por el MS. La participación de los movimientos sociales y el control ejercido por las representaciones sociales en el Consejo Municipal de Salud podrán revertir esa realidad.

Occupational accidents among mototaxi drivers.

The use of motorcycles as a means of work has contributed to the increase in traffic accidents, in particular, mototaxi accidents. The aim of this study was to estimate and characterize the incidence of occupational accidents among the mototaxis registered in Feira de Santana, BA. This is a cross-sectional study with descriptive and census data. Of the 300 professionals registered at the Municipal Transportation Service, 267 professionals were interviewed through a structured questionnaire. Then, a descriptive analysis was conducted and the incidence of accidents was estimated based on the variables studied. Relative risks were calculated and statistical significance was determined using the chi-square test and Fisher's exact test, considering p < 0.05. Logistic regression was used in order to perform simultaneous adjustment of variables. Occupational accidents were observed in 10.5% of mototaxis. There were mainly minor injuries (48.7%), 27% of them requiring leaves of absence from work. There was an association between the days of work per week, fatigue in lower limbs and musculoskeletal complaints, and accidents. Knowledge of the working conditions and accidents involved in this activity can be of great importance for the adoption of traffic education policies, and to help prevent accidents by improving the working conditions and lives of these professionals.

Spatial distribution of mortality by homicide and social inequalities according to race/skin color in an intra-urban Brazilian space.

INTRODUCTION: In Brazil, deaths by external causes rank first in the mortality statistics. Nevertheless, studies which investigate the relationship between mortality by external causes and race/skin color are scarce. OBJECTIVES: To evaluate the relative contribution of race/skin color to the spatial distribution of mortality by homicide in Salvador, state of Bahia, Brazil, in the period 1998 - 2003. MATERIAL AND METHODS: This is a spatial aggregate study including secondary data on 5,250 subjects, using a unit of analysis called the "weighting area" (WA). Annual average death rates by homicide were estimated. The Global and Local Moran Index were used to evaluate the presence of spatial autocorrelation and the Conditional Auto Regressive (CAR) model was employed to evaluate the referred effect, using the R statistical package. RESULTS: Global and Local Moran's I tests were significant. CAR regression showed that the predicted mortality rate increases when there is a growth in the proportion of black males aged between 15 and 49 years. Geometrically weighted regression (GWR) showed a very small variation of the local coefficients for all predictors. CONCLUSION: We demonstrated that the interrelation between race, violence and space is a phenomenon which results from a long process of social inequality. Understanding these interactions requires interdisciplinary efforts that contribute to advancement of knowledge that leads to more specific Public Health interventions.
