ABSTRACT Poverty, malnutrition and neglected tropical diseases such as soil-transmitted helminthiases (STHs) interact in a multi-causal feedback network. This study aimed to assess the relationships between STHs, income and nutritional status of children in impoverished communities in the city of Caxias, Maranhao State, Northeastern Brazil. A cross-sectional survey (n=259 children) was carried out with the collection of fecal samples and assessment of sociodemographic, anthropometric, dietary and sanitation data. Hookworm infection and ascariasis presented prevalence rates of 14.3% and 9.3%, respectively. The logistic regression analysis showed that hookworm infection was more frequent in males (odds ratio [OR]=3.43; 95% confidence interval [CI]=1.45-8.08), children aged 11-15 years old (OR=3.72; 95% CI=1.19-11.62), children living in poor families (OR=2.44; 95% CI=1.04-5.68) and those living in rented houses (OR=5.74; 95%CI=1.91-17.25). Concerning ascariasis, living in the Caldeiroes community (OR=0.01; 95%CI=0-0.17) and belonging to the 11-15 years age group (OR=0.21; 95%CI=0.04-1.02) were protection factors. Poor children have a significantly lower frequency of consumption of meat, milk, vegetables, tubers and fruits than not poor children. The frequent consumption of meat, milk and tubers was associated with significant higher values in the parameter height-for-age, whereas the consumption of meat and milk positively influenced the weight-for-age. The frequencies of stunting, underweight and wasting were 8.1%, 4.9% and 2.9%, respectively. The multivariate model demonstrated that stunting was significantly associated with economic poverty (OR=2.82; 95%CI=1.03-7.70) and low weight was associated with male sex (OR=6.43; 95% CI=1.35-30.68). In conclusion, the study describes the interactions between the dimensions of development represented by income, STHs and nutritional status revealing the importance of raising income levels to improve the living conditions of families in impoverished communities in Northeastern Brazil.

O presente trabalho, desenvolvido com os índios Xakriabá, em Minas Gerais, teve como objetivo conhecer as necessidades de tratamento odontológico buscando organizar o agendamento dos pacientes para tratamento. Os Agentes Indígenas de Saúde foram treinados por cirurgiões-dentistas para realizarem o levantamento nos domicílios. A população indígena total é de 6.498 habitantes, sendo que 3.686 estão na área de abrangência do Pólo Base Brejo Mata Fome, local onde 61% das pessoas foram examinadas. Os resultados mostraram haver uma população predominantemente jovem, um grande número de pessoas sem necessidade de tratamento e a cárie dentária foi o problema mais prevalente. Espera-se que o levantamento de necessidades venha contribuir para um agendamento no qual as pessoas que apresentam situações mais graves sejam priorizadas, buscando com isso promover a eqüidade.

The present study was developed among Xakriabas Indians in Minas Gerais and aimed at identifying their needs for dental treatment so that patients could be scheduled for treatment. Native health agents were trained by dental-surgeons for conducting the survey in household visits. The total Indian population is of 6.498 inhabitants, 3.686 of these living within the territory of the "Base Mata Fome", where 61% of the population was examined. Results showed that the population is mainly young, a great number of individuals presented no need for treatment and dental caries was the most frequent problem. The survey is expected to help in the organization of a schedule that allows giving priority to the more serious cases and promoting equity.
