Abstract

To determine the role of moderate- and low-intensity infections with and intestinal helminths (hookworm, ) on the prevalence of anemia and their relationship to iron consumption, a cross-section of 1,709 children in rural Brazil was studied. All participants were selected for infection with one or multiple helminthic parasites, and demographic, anthropometric, and dietary intake were surveyed. The prevalence and intensity were as follows: hookworm infection, 15.7% and 8.6 eggs/g; 74.8% and 190.5 eggs/g; 63% and 1,905.5 eggs/g; 44.5% and 60.3 eggs/g. There was no increase in odds ratio for anemia with any combination of intestinal helminths without infection. By logistic regression, the odds ratio for having anemia when infected with and two intestinal helminths was 1.7 (95% CI, 1.1–2.5) and for and three intestinal helminths was 2.4 (95% CI, 1.2–4.6) compared with children with a single parasite species. Children with an adequate intake of iron had no increased odds of anemia independent of the combination of parasite infections.
