RESUMEN
OBJECTIVE: To describe the space-time evolution of TB incidence rates (TI) in indigenous and non-indigenous people, according to the Federative Units (UF) of Brazil, from 2011 to 2022. METHODS: Ecological, temporal, and spatial study on new tuberculosis cases in Brazil among indigenous and non-indigenous populations. Data from the Notifiable Diseases Information System (Sinan) were collected from 2011 to 2022 and stratified by Federal Unit, explored and statistically analyzed using R software version 4.2.3. RESULTS: The mean TI among indigenous populations in Brazil was 71.7 new cases per 100,000 inhabitants, while for non-indigenous populations it was 28.6/100,000 inhabitants. The regions of the country that presented the highest (mean) incidence among indigenous populations were: Central-West (102.8/100,000 inhabitants), Southeast (99.6/100,000 inhabitants), and North (79.9/100,000 inhabitants). For non-indigenous populations the highest incidence was in the North region (36.5/100,000 inhabitants), followed by the Southeast (31.3/100,000), and the Northeast (27,4/100,000 inhabitants). The analysis showed that the highest incidence of TB cases among indigenous populations occurred in the states of: SP, RO, RJ, MS, MT e PA. CONCLUSION: High incidence of the disease compared to the non-indigenous population show the need for a specific approach to address the health needs of these populations. Regional disparities in incidence indicate the need to address socioeconomic and infrastructure issues that affect the health of indigenous populations.

RESUMO Objetivo: Descrever a evolução espaço-temporal das taxas de incidência (TIs) de tuberculose (TB) em indígenas e não indígenas, segundo as unidades federativas do Brasil, no período de 2011 a 2022. Métodos: Estudo ecológico, temporal e espacial sobre os casos novos de tuberculose no Brasil em indígenas e não indígenas. Dados provenientes do Sistema de Informação de Agravos de Notificação (SINAN) foram coletados de 2011 a 2022 e estratificados por UF, analisados exploratória e estatisticamente por meio do software R 4.2.3. Resultados: A TI média entre indígenas no Brasil foi 71,7 casos novos para cada 100 mil habitantes, enquanto para não indígenas foi de 28,6/100 mil habitantes. As regiões do país que apresentaram as maiores incidências (médias) para indígenas foram: Centro-Oeste (102,8/100 mil hab.), Sudeste (99,6/100 mil hab.) e Norte (79,9/100 mil hab.), e para não indígenas foram: Norte (36,5/100 mil hab.), Sudeste (31,3/100 mil hab.) e Nordeste (27,4/100 mil hab.). A análise mostrou que a maior incidência de casos de TB nas populações indígenas ocorreu nos estados de São Paulo, Rondônia, Rio de Janeiro, Mato Grosso do Sul, Mato Grosso e Pará. Conclusão: Altas incidências da doença em comparação com a população não indígena mostraram a necessidade de abordagem específica para atender às necessidades de saúde dessas populações. As disparidades regionais nas incidências indicaram a necessidade de abordar questões socioeconômicas e de infraestrutura que afetam a saúde desses povos.
RESUMEN
This paper is an exploratory study that examines the illegal goldmining impacts on Munduruku communities' "Good-Living" (Xipan Jewewekukap) and explores the possible relationship between chronic methylmercury (MeHg) exposure and the worsening mental health conditions in three villages in the Middle-Tapajós River, Brazilian Amazon. The region has been experiencing a long-lasting threat of goldminers' invasions. A total of 109 people were interviewed and evaluated. Total mercury (THg) exposure levels were evaluated through hair samples analysis, from which MeHg exposure levels were calculated. The Geriatric Depression Scale-Short Form (GDS-SF) was used as a screening tool in order to assess mental health indicators. Brief non-structured interviews were carried out to investigate how goldmining is impacting the communities Good-Living. A Poisson regression model was used to estimate the possible association between mental health indicators (assessed through the GDS-SF) and the following independent variables: (i) mercury exposure level (<10.0 µg/g vs. ≥10.0 µg/g), (ii) self-reported nervousness, (iii) self-reported irritability, (iv) age group, and (v) monthly income. The analysis revealed high levels of mercury in hair samples (median: 7.4 µg/g, range 2.0-22.8; 70% and 28% of the participants had THg levels ≥6.0 and ≥10.0 µg/g, respectively) and pointed to a tendency in which higher levels of methylmercury exposure (Hg ≥ 10.0 µg/g) could be linked to worse mental health indicators. Although the GDS-SF has presented limitations due to the Munduruku sociocultural context, our findings suggest a tendency of worse mental health indicators in participants presenting high levels of MeHg exposure. Despite this limitation, the qualitative approach indicates an evident association between the impacts of goldmining and the Munduruku people's decreasing autonomy to maintain a Good-Living on their own terms, pointing to the importance of carrying out new investigations, especially considering longitudinal studies with qualitative methodologies and ethnographic approaches.

The Amazonian indigenous peoples depend on natural resources to live, but human activities' growing impacts threaten their health and livelihoods. Our objectives were to present the principal results of an integrated and multidisciplinary analysis of the health parameters and assess the mercury (Hg) exposure levels in indigenous populations in the Brazilian Amazon. We carried out a cross-sectional study based on a census of three Munduruku indigenous villages (Sawré Muybu, Poxo Muybu, and Sawré Aboy), located in the Sawré Muybu Indigenous Land, between 29 October and 9 November 2019. The investigation included: (i) sociodemographic characterization of the participants; (ii) health assessment; (iii) genetic polymorphism analysis; (iv) hair mercury determination; and (v) fish mercury determination. We used the logistic regression model with conditional Prevalence Ratio (PR), with the respective 95% confidence intervals (CI95%) to explore factors associated with mercury exposure levels ≥6.0 µg/g. A total of 200 participants were interviewed. Mercury levels (197 hair samples) ranged from 1.4 to 23.9 µg/g, with significant differences between the villages (Kruskal-Wallis test: 19.9; p-value < 0.001). On average, the general prevalence of Hg exposure ≥ 6.0 µg/g was 57.9%. For participants ≥12 years old, the Hg exposure ≥6.0 µg/g showed associated with no regular income (PR: 1.3; CI95%: 1.0-1.8), high blood pressure (PR: 1.6; CI95%: 1.3-2.1) and was more prominent in Sawré Aboy village (PR: 1.8; CI95%: 1.3-2.3). For women of childbearing age, the Hg exposure ≥6.0 µg/g was associated with high blood pressure (PR: 1.9; CI95%: 1.2-2.3), with pregnancy (PR: 1.5; CI95%: 1.0-2.1) and was more prominent among residents in Poxo Muybu (PR: 1.9; CI95%: 1.0-3.4) and Sawré Aboy (PR: 2.5; CI95%: 1.4-4.4) villages. Our findings suggest that chronic mercury exposure causes harmful effects to the studied indigenous communities, especially considering vulnerable groups of the population, such as women of childbearing age. Lastly, we propose to stop the illegal mining in these areas and develop a risk management plan that aims to ensure the health, livelihoods, and human rights of the indigenous people from Amazon Basin.

OBJECTIVES: This study aimed to analyze the factors associated with likely TB deaths, likely TB-related deaths and deaths from other causes. Understanding the factors associated with mortality could help the strategy to End TB, especially the goal of reducing TB deaths by 95% between 2015 and 2035. METHODS: A retrospective, population-based cohort study of the causes of death was performed using a competing risk model in patients receiving treatment for TB. Patients had started TB treatment in Brazil 2008-2013 with any death certificates dated in the same period. We used three categories of deaths, according to ICD-10 codes: i) probable TB deaths; ii) TB-related deaths; iii) deaths from other causes. RESULTS: In this cohort, 39,997 individuals (14.1%) died, out of a total of 283,508 individuals. Of these, 8,936 were probable TB deaths (22.4%) and 3,365 TB-related deaths (8.4%), illustrating high mortality rates. 27,696 deaths (69.2%) were from other causes. From our analysis, factors strongly associated with probable TB deaths were male gender (sHR = 1.33, 95% CI: 1.26-1.40), age over 60 years (sHR = 9.29, 95% CI: 8.15-10.60), illiterate schooling (sHR = 2.33, 95% CI: 2.09-2.59), black (sHR = 1.33, 95% CI: 1.26-1.40) and brown (sHR = 13, 95% CI: 1.07-1.19) color/race, from the Southern region (sHR = 1.19, 95% CI: 1.10-1.28), clinical mixed forms (sHR = 1.91, 95% CI: 1.73-2.11) and alcoholism (sHR = 1.90, 95% CI: 1.81-2.00). Also, HIV positive serology was strongly associated with probable TB deaths (sHR = 62.78; 95% CI: 55.01-71.63). CONCLUSIONS: In conclusion, specific strategies for active surveillance and early case detection can reduce mortality among patients with tuberculosis, leading to more timely detection and treatment.

The study aimed to describe clinical and sociodemographic characteristics, estimate incidence, and analyze factors associated with dropout and death during treatment of TB cases reported in indigenous children and adolescents in Brazil from 2006 to 2016. A historical case series was performed on incidence according to age bracket and major geographic region, and multinomial logistic regression was used to explain factors associated with treatment dropout and death. Of the 2,096 reported cases, 88.2% evolved to cure, 7.2% dropped out of treatment, and 4.6% evolved to death. There was a predominance of cases in boys 15-19 years of age and a higher proportion of deaths (55.7%) in children < 4 years. Considering indigenous children and adolescents with TB in Brazil as a whole, mean incidence was 49.1/100,000, ranging from 21.5/100,000 to 97.6/100,000 in the Northeast and Central, respectively. Cases with insufficient and irregular follow-up showed higher odds of dropout (OR = 11.1; 95%CI: 5.2-24.8/OR = 4.4; 95%CI: 1.9-10.3) and death (OR = 20.3; 95%CI: 4.9-84.9/OR = 5.1; 95%CI: 1.2-22.7). Cases in retreatment (OR = 2.4; 95%CI: 2.08-8.55) and with HIV coinfection (OR = 8.2; 95%CI: 2.2-30.9) were also associated with dropout. Extrapulmonary (OR = 1.8; 95%CI: 1.1-3.3) and mixed clinical forms (OR = 5.6; 95%CI: 2.8-11.4), age < 4 years (OR = 3.1; 95%CI: 1.5-6.4), and cases from the North (OR = 2.8; 95%CI: 1.1-7.1) and Central (OR = 2.8; 95%CI: 1.1-7.0) were associated with death. TB control in indigenous children and adolescents cannot be achieved without investments in research and development and without reducing social inequalities.

Realizou-se análise da série histórica de incidência, segundo faixa etária e macrorregião e utilizou-se regressão logística multinomial para elucidar fatores associados ao abandono e ao óbito. Do total de 2.096 casos notificados, 88,2% tiveram cura, 7,2% abandonaram o tratamento e 4,6% evoluíram para óbito. Houve predomínio de casos em meninos de 15-19 anos e maior proporção de óbitos (55,7%) em < 4 anos. Considerando o conjunto de crianças e adolescentes indígenas com TB no Brasil, a incidência média foi 49,1/100 mil, variando de 21,5/100 mil a 97,6/100 mil nas regiões Nordeste e Centro-oeste, respectivamente. Os casos com acompanhamento insuficiente e regular tiveram maiores chances de abandono (OR = 11,1; IC95%: 5,2-24,8/OR = 4,4; IC95%: 1,9-10,3) e óbito (OR = 20,3; IC95%: 4,9-84,9/OR = 5,1; IC95%: 1,2-22,7). Os casos em retratamento (OR = 2,4; IC95%: 2,08-8,55) e com anti-HIV positivo (OR = 8,2; IC95%: 2,2-30,9) também mostraram-se associados ao abandono. As formas clínicas extrapulmonar (OR = 1,8; IC95%: 1,1-3,3) e mista (OR = 5,6; IC95%: 2,8-11,4), os casos em < 4 anos (OR = 3,1; IC95%: 1,5-6,4) e os casos provenientes das regiões Norte (OR = 2,8; IC95%: 1,1-7,1) e Centro-oeste (OR = 2,8; IC95%: 1,1-7,0) mostraram-se associados ao óbito. Acreditamos que o controle da TB em crianças e adolescentes indígenas não poderá ser alcançado sem investimentos em pesquisa e desenvolvimento e sem a redução das desigualdades sociais.

Drug-resistant tuberculosis (DR-TB) poses a serious threat to tuberculosis (TB) control in Brazil and worldwide. The current study investigated factors associated with loss to follow-up and death in the course of treatment for DR-TB in a tertiary reference center in the city of Rio de Janeiro, Brazil. This was a retrospective cohort study of cases reported to the Information System on Special Treatments for Tuberculosis (SITETB) from January 1, 2012, to December 31, 2013. A total of 257 patients were reported to the SITETB and initiated treatment for DR-TB. Of this total, 139 (54.1%) achieved treatment success as the outcome, 54 (21%) were lost to follow-up, and 21 (8.2%) died. Following a multiple multinomial logistic regression analysis, the age bracket older than 50 years was the only protective factor against loss to follow-up, whereas less than eight years of schooling and reentry after loss to follow-up were considered risk factors. Reentry after loss to follow-up, relapse, and treatment failure appeared as risk factors. Our data reinforce the concept that loss to follow-up in drug-resistant tuberculosis is a serious public health problem, and that adequate follow-up of treatment is necessary in patients with this history and low schooling. A social support network for patients is also indispensable for avoiding unfavorable outcomes.
A tuberculose drogarresistente (TBDR) representa hoje uma grave ameaça aos avanços no controle da tuberculose (TB) no Brasil e no mundo. Neste estudo, investigam-se fatores associados ao abandono e ao óbito de casos em tratamento para TBDR, em um centro de referência terciária do Município do Rio de Janeiro, Brasil. Trata-se de um estudo de coorte retrospectiva, a partir dos casos notificados no Sistema de Informação de Tratamentos Especiais de Tuberculose (SITETB), no período de 1º de janeiro de 2012 a 31 de dezembro de 2013. Um total de 257 pacientes foi notificado no SITETB e iniciou o tratamento para TBDR. Desse total, 139 (54,1%) tiveram sucesso terapêutico como desfecho, 54 (21%) abandonaram o tratamento e 21 (8,2%) evoluíram para óbito. Após análise de regressão logística multinomial múltipla, a faixa etária acima de cinquenta anos foi observada como único fator de proteção ao abandono, ao passo que ter menos de oito anos de escolaridade e reingresso após abandono foram considerados como fatores de risco. Reingresso após abandono, recidiva e falência indicaram fatores de risco. Nossos dados reforçam a concepção de que o abandono do tratamento de tuberculose resistente é um sério problema de saúde pública, sendo necessário um adequado acompanhamento no tratamento de pacientes com esse histórico e com baixa escolaridade. Além disso, uma rede de apoio social ao paciente é imprescindível para que desfechos desfavoráveis sejam evitados.
La tuberculosis farmacorresistente (TBFR) representa hoy una grave amenaza para los avances en el control de la tuberculosis (TB) en Brasil y en el mundo. En este estudio, se investigan factores asociados al abandono y al óbito de casos en tratamiento para TBDR, dentro de un centro de referencia de carácter terciario del municipio de Río de Janeiro, Brasil. Se trata de un estudio de cohorte retrospectiva, a partir de los casos notificados en el Sistema de Información de Tratamientos Especiales de Tuberculosis (SITETB), durante el período del 1 de enero de 2012 al 31 de diciembre de 2013. Un total de 257 pacientes fue notificado en el SITETB y comenzó el tratamiento para TBDR. De ese total, 139 (un 54,1%) tuvieron éxito terapéutico como desenlace, 54 (un 21%) abandonaron el tratamiento y un 21 (8,2%) evolucionaron hacia óbito. Tras el análisis de regresión logística multinomial múltiple, la franja de edad por encima de cincuenta años se observó como el único factor de protección al abandono, al mismo tiempo que tener menos de ocho años de escolaridad y reingresar en el sistema educativo tras el abandono fueron considerados como factores de riesgo. Reingreso tras abandono, recidiva e insolvencia indicaron factores de riesgo. Nuestros datos refuerzan la concepción de que el abandono del tratamiento de tuberculosis resistente es un serio problema de salud pública, siendo necesario un adecuado acompañamiento en el tratamiento de pacientes con este historial y con baja escolaridad. Además, una red de apoyo social entorno al paciente es imprescindible para que los desenlaces desfavorables sean evitados.

Resumo: A tuberculose drogarresistente (TBDR) representa hoje uma grave ameaça aos avanços no controle da tuberculose (TB) no Brasil e no mundo. Neste estudo, investigam-se fatores associados ao abandono e ao óbito de casos em tratamento para TBDR, em um centro de referência terciária do Município do Rio de Janeiro, Brasil. Trata-se de um estudo de coorte retrospectiva, a partir dos casos notificados no Sistema de Informação de Tratamentos Especiais de Tuberculose (SITETB), no período de 1º de janeiro de 2012 a 31 de dezembro de 2013. Um total de 257 pacientes foi notificado no SITETB e iniciou o tratamento para TBDR. Desse total, 139 (54,1%) tiveram sucesso terapêutico como desfecho, 54 (21%) abandonaram o tratamento e 21 (8,2%) evoluíram para óbito. Após análise de regressão logística multinomial múltipla, a faixa etária acima de cinquenta anos foi observada como único fator de proteção ao abandono, ao passo que ter menos de oito anos de escolaridade e reingresso após abandono foram considerados como fatores de risco. Reingresso após abandono, recidiva e falência indicaram fatores de risco. Nossos dados reforçam a concepção de que o abandono do tratamento de tuberculose resistente é um sério problema de saúde pública, sendo necessário um adequado acompanhamento no tratamento de pacientes com esse histórico e com baixa escolaridade. Além disso, uma rede de apoio social ao paciente é imprescindível para que desfechos desfavoráveis sejam evitados.
Resumen: La tuberculosis farmacorresistente (TBFR) representa hoy una grave amenaza para los avances en el control de la tuberculosis (TB) en Brasil y en el mundo.

Abstract: Drug-resistant tuberculosis (DR-TB) poses a serious threat to tuberculosis (TB) control in Brazil and worldwide. The current study investigated factors associated with loss to follow-up and death in the course of treatment for DR-TB in a tertiary reference center in the city of Rio de Janeiro, Brazil. This was a retrospective cohort study of cases reported to the Information System on Special Treatments for Tuberculosis (SITETB) from January 1, 2012, to December 31, 2013. A total of 257 patients were reported to the SITETB and initiated treatment for DR-TB. Of this total, 139 (54.1%) achieved treatment success as the outcome, 54 (21%) were lost to follow-up, and 21 (8.2%) died. Following a multiple multinomial logistic regression analysis, the age bracket older than 50 years was the only protective factor against loss to follow-up, whereas less than eight years of schooling and reentry after loss to follow-up were considered risk factors. Reentry after loss to follow-up, relapse, and treatment failure appeared as risk factors. Our data reinforce the concept that loss to follow-up in drug-resistant tuberculosis is a serious public health problem, and that adequate follow-up of treatment is necessary in patients with this history and low schooling. A social support network for patients is also indispensable for avoiding unfavorable outcomes.

OBJECTIVE: This study analysed clinical and sociodemographic aspects and follow-up for notified cases of tuberculosis (TB) and explored inequalities in incidence rates and outcome by colour or race and the geographic macro-regions of Brazil. METHODS: This paper reports the results of a population-based descriptive epidemiological study of all notified cases of TB in Brazil during the period from 01/01/2008 to 31/12/2011. We analysed sociodemographic and clinical variables according to colour or race (white, black, Asian, mixed, and indigenous) and geographic macro-regions of the country (North, Northeast, Central-West, South, and Southeast). RESULTS: During the study period, the average incidence of TB in Brazil was 36.7 cases per 100,000 inhabitants, with the highest rates occurring in the North and Southeast regions. The analysis of TB notifications by colour or race revealed that the indigenous population presented the highest incidence rates in all macro-regions except the South, where higher rates were reported in black patients. 'Cured' was the most frequently reported treatment outcome for all skin colour categories. The highest cure rate occurred among the indigenous population (76.8%), while the lowest cure rate occurred among the black population (70.7%). Rates of treatment default were highest among blacks (10.5%) and lowest among the indigenous population (6.9%). However, the fatality rate was similar across race categories, varying between 2.8% and 3.8% for whites and the indigenous population, respectively. The lowest cure rates were observed when follow-up was inadequate (58.3%), and the highest was observed when the follow-up was classified as excellent (96.8%). CONCLUSIONS: This study revealed that-apart from the heterogeneous distribution of TB among the Brazilian macro-regions-ethnic-racial inequalities exist in terms of clinical-epidemiological characteristics and incidence rates as well as follow-up for cases undergoing treatment. The highest rates of TB occurred among the indigenous people.

Introdução: A tuberculose (TB) é um dos principais problemas de saúde no Brasil, atingindo principalmente os povos indígenas. Portanto, o objetivo deste estudo foi descrever a situação epidemiológica da TB segundo raça/cor no Brasil, no período de 2008-2011. Métodos: Estudo descritivo e retrospectivo, que teve como fonte de dados os casos novos de TB notificados no Sistema de Informação de Agravos de Notificação (Sinan). Foram calculadas as Taxas de Incidência (TI) de TB por 100.000 habitantes para o Brasil e suas macrorregiões, e analisadas as variáveis sociodemográficas (sexo, faixa etária, escolaridade e zona de residência) e clínicas (forma clínica, exames complementares empregados para o diagnóstico e coinfecção tuberculose/HIV), além de indicadores de desempenho do programa (tratamento supervisionado, baciloscopias de controle no segundo, quarto e sexto meses de tratamento, exames de contato e situação de encerramento), segundo as categorias de raça/cor (branca, preta, amarela, parda e indígena). Os dados foram estruturados no Microsoft Excel 2010 e analisados no SPSS (versão 20.0). Resultados: No período de estudo foram notificados 278.674 casos novos no Brasil, correspondendo a uma incidência média de 36,7/100.000 habitantes. As TI segundo raça/cor revelam que no Brasil os indígenas apresentaram as maiores incidências, registrando-se aumento de 95,4/100.000 em 2008 para 104/100.000 em 2011, um incremento de aproximadamente 10 por cento. Houve predomínio de casos em doentes do sexo masculino e em indivíduos de 20 a 44 anos em todas as categorias de raça/cor. Quanto à escolaridade, observou-se que os indígenas apresentaram o maior porcentual de analfabetismo (16,0 por cento). No que diz respeito à procedência das notificações, 66,3 por cento eram da zona urbana. A forma clínica pulmonar foi a mais frequente: 82,3 por cento em todas as categorias. O teste de anti-HIV não foi oferecido a 33,4 por cento dos casos. Quanto à situação de encerramento, houve predomínio de cura em todas as categorias de raça / cor, porém, os porcentuais mais elevados foram registrados entre os indígenas (76,8 por cento). Os maiores porcentuais de óbitos por TB foram entre os pretos (3,4 por cento). Quanto às baciloscopias de controle, os brancos apresentaram os maiores porcentuais de positividade nos segundo e quarto meses (5,3 por cento e 1,1 por cento, respectivamente), já os amarelos no sexto mês (0,7 por cento). O maior porcentual de tratamento supervisionado foi entre os indígenas (68,6 por cento). Conclusões: Nossos achados ajudaram a compreender as disparidades no adoecimento por TB, de acordo com a classificação étnica vigente no Brasil. Diante disso, acreditamos que para a elaboração de estratégias efetivas as autoridades brasileiras devam desenvolver estratégias de controle da TB específicas, considerando as diferenças de cada grupo específico, com foco nos doentes de raça/cor indígenas e pretos, abordando os determinantes sociais de saúde nestes grupos.
Introduction: Tuberculosis (TB) remains one of the major health problems in Brazil, affecting mainly indigenous peoples. Therefore, the aim of this study was to describe the epidemiological situation of TB by race / color in Brazil, in the period 2008-2011. Methods: A descriptive, retrospective study , which had as its data source new cases of TB reported in the Information System for Notifiable Diseases (Sinan). Incidence Rate (IR) of TB were calculated per 100,000 population for Brazil and its macro-regions and analyzed sociodemographic variables (gender, age, education and zone of residence ) and clinical (clinical form, additional tests used for diagnosis tuberculosis and coinfection/HIV), and performance indicators of the program (supervised treatment, sputum smear control in the second, fourth and sixth month of treatment, exams of contact and outcome treatment), according to the categories of race/color (white, black, yellow, brown and indigenous). The data were structured in Microsoft Excel 2010 and analyzed by SPSS (version 20.0). Results: During the study period 278 674 new cases were reported in Brazil, corresponding to an average incidence of 36.7/100.000. The IR by race/color reveal that in Brazil, the indigenous showed the highest percentages, recording an increase of 95.4/100,000 in 2008 to 104/100.000 in 2011, an increase of approximately 10 per cent. There was a predominance of cases in male patients and in individuals 20-44 years of all categories of race/color. As for education, we observed that the natives had the highest percentage of illiteracy (16.0 per cent). As the validity of notifications, 66.3 per cent were from urban zone. Pulmonary TB was the most frequent 82.3 per cent in all categories. The anti-HIV was not offered to 33.4 per cent of cases. Regarding the outcome treatment predominated healing in all categories of race / color, however, the highest percentages were recorded among indigenous (76.8 per cent). The largest percentage of TB deaths was among blacks (3.4 per cent). As the bacilloscopies control, whites had higher percentages of positivity on the 2nd and 4th month (5.3 per cent and 1.1 per cent, respectively), as yellow at 6 months (0.7 per cent). The highest percentage of supervised treatment was among indigenous (68.6 per cent). Conclusions: Our findings helped to understand the disparities in rates of active TB, according to the prevailing racial classification in Brazil. Therefore, we believe that for the development of effective strategies, the Brazilian authorities should develop specific strategies to control TB, considering the differences of each specific group, focusing on patient race/color black and indigenous addressing the social determinants of health these groups.
