The purpose of this investigation was to analyze the distribution of protein-energy malnutrition, anemia and hypovitaminosis A in relation to accessibility and size of rural lands. About 689 families from the Agreste rural area (Pernambuco, North-East Brazil) were studied. A total of 1,257 children under 6 years of age were distributed in four groups according to the size of the land. The nutritional status was assessed according to the criteria of Gómez, Ariza-Macías and Seoane-Latham, modified by Batista Filho. In accordance with the Gómez' method, 55.1% of the children suffered from some degree of malnutrition. About 67.0% of the landless families suffered from malnutrition, in contrast to 25% of the landowners who had 50 or more than 50 hectares of land (p less than 0.01). Hemoglobin was determined in 976 children; 38.9% of them suffered from anemia. No significant differences were detected among the several groups of land tenants. Serum retinol levels were measured in 412 children and a high incidence of hypovitaminosis A was detected: 24% had serum retinol levels below 20 mcg/100 ml. No significant association was found in relation to the different land tenure groups. These data demonstrate a high prevalence of protein-energy malnutrition, anemia and hypovitaminosis A. A significant correlation between protein-energy malnutrition and the size of the land was also found, demonstrating that this region is one of the most affected by food and nutritional problems.
