Anemia is the most common manifestation of disease observed in the tropics. Iron-deficiency anemia affects about 1.3 billion people, with the highest prevalence and morbidity in young children and pregnant women (Gillespie et al., 1991). It is estimated that up to half of school-age children in developing countries are anemic (DeMaeyer et al., 1989). Anemia in infants and children is associated with increased mortality (Stoltzfus, 1997), growth retardation (Angeles et al., 1993), delayed motor development, poor cognitive abilities (Watkins & Pollitt, 1998), reduced school performance (Lozoff et al., 1991), and an impaired immune system (Dallman, 1987).
Schoolchildren are an easily identified target group, and schools could be used as a distribution system for public health. However, interventions must be based on epidemiological information concerning the main local causes of anemia. Most Latin America countries lack such information, and the Pan-American Health Organization of the World Health Organization (PAHO/WHO) has proposed collecting the necessary information (Freire, 1997).
This study aimed to establish the prevalence of anemia, intestinal parasites, and nutritional status of children attending primary schools in Aracaju, Brazil.
