RESUMEN

The objective of this survey was to assess the relationships between intestinal parasitism, nutritional status and hemoglobin level in children with Indian ascendancy living in an urban area in Brazilian Amazon. We carried out a cross-sectional survey obtaining anthropometric, parasitological and socioeconomic data, and hemoglobin measurements of children aged six to 84 months. Anthropometric data were expressed as z-scores for weight for age (WAZ), height for age (HAZ), weight for height (WHZ) and mid upper circumference for age (MUACZ) parameters. Parasitological examinations were performed through Ritchie (n = 307), Kato-Katz (n = 278), Baermann-Moraes (n = 238) and Safranin-methylene blue methods (n = 307). Hemoglobin measurements were obtained with a Hemocue photometer (n = 282). Socioeconomic data were used in order to classify children in three family income strata (n = 242). Multiple linear regression analysis showed independent interactions between Giardia lamblia and WAZ (beta = -0.195, SE = 0.138, p = 0.003), WHZ (beta = -0.161, SE = 0.133, p = 0.018) and MUACZ (beta = -0.197, SE = 0.143, p = 0.011), controlling for age, sex, family income, Ascaris lumbricoides, and hookworm infection. Also, the multivariate model showed that the only variable associated with hemoglobin levels was age. Intestinal parasitism control should increase children's possibilities of full development in the studied area.

O presente estudo objetivou avaliar a relação entre as parasitoses intestinais, o status nutricional e os níveis de hemoglobina em crianças vivendo em uma área urbana na Amazônia Brasileira. Foi realizado um estudo seccional, obtendo-se dados antropométricos, parasitológicos e socioeconômicos, além de dosagens de hemoglobina através do fotômetro Hemocue®, de crianças com idade entre seis e 84 meses. Os dados da antropometria foram expressos como escores de desvio-padrão (escores z) para os parâmetros peso-idade (PI), altura-idade (AI), peso-altura (PA) e perímetro braquial-idade (PBI). Os exames parasitológicos foram realizados através dos métodos de Ritchie (n = 307), Kato-Katz (n = 278), Baermann-Moraes (n = 238) e Safranina-Azul-de-Metileno (n = 307). A regressão linear múltipla demonstrou interações independentes entre Giardia lamblia e PI (beta = -0.195, p = 0.003), PA (beta = -0.161, p = 0.018) e PBI (beta = -0.197, p = 0.011), após controle para idade, sexo, renda familiar e infecções por Ascaris lumbricoides e ancilostomídeos. O modelo multivariado demonstrou ainda que a única variável associada aos níveis de hemoglobina foi a idade. O estudo concluiu que a giardíase está associada, nos sujeitos pesquisados, a menores médias para os parâmetros antropométricos estudados e que um controle efetivo das parasitoses intestinais poderia contribuir para o pleno desenvolvimento das crianças na área estudada.
