[Anemia and deficiency of vitamin A in children evaluated in a nutritional attention center from Caracas].

In order to determine the prevalence of anemia and the deficiency of vitamin A in children under 10 years, the concentration of hemoglobin, transferrin saturation, serum iron and the nutritional state of vitamin A were studied between 1999 and 2000, in 124 children with moderate malnutrition and 98 healthy children who attend triage consultation in the Centro de Atención Nutricional Infantil Antímano (CANIA, Caracas) by means of plasma retinol test (high performance liquid chromatography), relative dose response test (RDR) and conjunctival impression cytology (CIC). The dietary intake was analyzed by 24 hour recall. The Student t and Chi-square test were used for the statistical analysis of the data. The prevalence of vitamin A deficiency was approximately 10% in malnourished and healthy children, the CIC test discriminated a proportion of vitamin A deficient children superior to 25% and RDR test detected a significantly smaller percentage of deficiency in healthy children (p < 0.05). The prevalence of anemia was significantly higher in malnourished (34.2%) than in healthy children (19.2%). In children under 2 years the percentage of anemia reached 75.8% in undernourished children and 50% in healthy children. The consumption of macronutrients and micronutrients was inadequate; more than 40% undernourished children had caloric and macronutrients intake adequacy below 85%, whereas this level of adequacy in healthy children was around 30%. These results indicate there were problems of moderate anemia and moderate vitamin A deficiency in the studied infantile population, without significant differences between moderate undernourished and healthy children.
