RESUMOOBJETIVO: Verificar a incidência de hemoglobinas de descendência africana (HbS e HbC) em comunidades quilombolas do estado do Tocantins, Brasil. MATERIAIS E MÉTODOS: Foi coletado o sangue de quilombolas em 14 comunidades do Estado; a triagem foi realizada em eletroforese de acetato de celulose (pH 8,6), e aquelas com padrão alterado foram submetidas à cromatografia líquida de alta eficiência, sendo registrados o gênero e a idade das pessoas amostradas. RESULTADOS: A análise dos resultados demonstrou que, dos 822 quilombolas investigados, 95 apresentaram hemoglobinas anormais, sendo 0,5% com doença falciforme (HbSS); 5,7% traço para hemoglobina S (HbAS); 4,9% traço para hemoglobina C (HbAC); 0,2% com hemoglobina fetal aumentada; 0,1% com hemoglobina A 2 aumentada; e 88,4% com hemoglobina normal (HbAA). HbSS foi observada na faixa etária infantil e adolescente e HbAS e HbAC em todas as faixas etárias. Em relação ao sexo, não foi possível sugerir o efeito materno para HbS, devido ao maior quantitativo de pessoas do sexo masculino com essa informação genética. CONCLUSÃO: Neste estudo, a incidência das HbS e HbC, observada nas comunidades quilombolas, esteve dentro do esperado para a Região Norte do Brasil. No entanto, destacam-se a elevada prevalência da doença falciforme e a grande frequência de traço falciforme em algumas das comunidades estudadas, com atenção especial para a região sul do Estado. Desse modo, os resultados aqui apresentados sinalizam risco iminente para o aumento da incidência da doença no Tocantins.Palavras-chave: Anemia Falciforme; Traço Falciforme; Hemoglobina C; Hemoglobina Falciforme.Correspondência / Correspondence: Carla Simone Seibert Rua 03, lote 17, s/n.

MATERIALS AND METHODS: Blood samples were collected from 14 quilombola communities in the State; the screening was performed in cellulose acetate electrophoresis (pH 8.6), and those samples with altered standard were submitted to high performance liquid chromatography, recording gender and age of the quilombola people. RESULTS: The analysis of the results showed that of the 822 quilombolas investigated 95 presented abnormal hemoglobins, 0.5% with sickle cell disease (HbSS); 5.7% for hemoglobin S trait (HbAS); 4.9% for hemoglobin C trait (HbAC); 0.2% with increased fetal hemoglobin; 0.1% with increased hemoglobin A 2 ; and 88.4% with normal hemoglobin (HbAA). HbSS was observed in infant and adolescent groups and HbAS and HbAC in all age groups. About sex, it was not possible to suggest the maternal effect for HbS due to the greater quantitative of males with this genetic information. CONCLUSION: In the current study the incidence of HbS and HbC observed in quilombola communities was within the expected range for the Northern Reg...

The present study carried out a descriptive approach on the living conditions of families in some quilombola communities in the state of Tocantins. Through the application of a structured questionnaire, 414 families were interviewed, distributed in 21 quilombola communities in the State. From the interviews, it was observed that the communities were formed by a higher percentage of male quilombolas, in the adult age group. Many families had an income of up to one minimum wage, a value also made possible by the Bolsa Família Program, which complements the income of these families. In addition, a significant percentage of the residents engaged in farming and/or handicraft activities, and most of the population had Elementary School I (5th grade) as an educational level. The results of this study revealed that, despite having improved the access of quilombola communities to schools, many families are low-income and still lack basic sanitation and electricity in their homes. Therefore, the information presented here can contribute to the implementation of public policies aimed at quilombola communities in Tocantins.
