The entire scientific production relating to nutrition in the State of Amazonas, Brazil, during the last decades was critically revised. Analysis of this material, complemented by our own recent investigations, provided the basis for the diagnosis of hypovitaminosis A in the Amazon Region. The clinical - opthalmological investigation involved 487 children of both sexes between two and five years old, from Nhamundá and Alvarães, Anamã and Beruri in State of Amazonas. Serum retinol was determined only in 48 children from Nhamundá municipality. The clinical investigation did not detect any signs or symptoms indicative of vitamin A deficiency. Normal or high levels of serum retinol were found in 75% and 25%, respectively, of the study sample. These results, when added to those derived from the regional litterature, preclude any categorical affirmation that hypovitaminosis A constitutes a public health problem in the Amazon region.
