This study describes the epidemiological aspects of TB among Brazilian Native Indians aged less than 15 years-old in Mato Grosso do Sul, Brazil, between 2000 and 2006.
A retrospective observational study based on secondary data collected from the health system of Brazilian indigenous peoples, Special Indigenous Sanitary District (DSEI), and National System of Notifiable Diseases (SINAN) databases. The variables analyzed were: frequency of TB according to sex, age, clinical presentation and outcome. The Fisher test and the incidence tendency curve were calculated (p<0.01).
TB prevalence was 20.4% (224/1,096). The incidence rate decreased 14% per year during the study period. TB was more prevalent among Brazilian indigenous individuals aged less than 5 years-old and among those aged less than one year-old. More than half of TB cases were male and the most common clinical presentation was pulmonary TB (92.9%). Cure was the most common outcome (91.1%), followed by abandoned treatment (3.6%) and death (2.2%).
The high cure rate, reduced mortality and the progressive decrease in TB incidence rate during the study period indicate the effectiveness of supervised treatment of the new TB control model implemented among Brazilian indigenous peoples on 2000.
本研究描述了2000年至2006年期间，巴西南马托格罗索州15岁以下巴西原住民中结核病的流行病学情况。
一项基于从巴西原住民卫生系统、特殊原住民卫生区（DSEI）和国家法定疾病监测系统（SINAN）数据库收集的二手数据的回顾性观察研究。分析的变量包括：按性别、年龄、临床表现和结局划分的结核病发病率。计算了费舍尔检验和发病趋势曲线（p<0.01）。
结核病患病率为20.4%（224/1096）。在研究期间，发病率每年下降14%。结核病在5岁以下的巴西原住民个体以及1岁以下的个体中更为普遍。超过一半的结核病病例为男性，最常见的临床表现是肺结核（92.9%）。治愈是最常见的结局（91.1%），其次是放弃治疗（3.6%）和死亡（2.2%）。
高治愈率、降低的死亡率以及研究期间结核病发病率的逐步下降表明，2000年在巴西原住民中实施的新结核病控制模式的督导治疗是有效的。
