摘要
objectives: to identify the prevalence of iron deficiency in the population studied, as well as verifying if such deprivation is associated with vitamin a deficiency. methods: one hundred seventy-nine children, %26gt; 24 months and %26lt; 72 months of age, with no diarrhea and/or fever at collection were studied. vitamin a deficiency identification was carried out through serum 30-day dose-response test. samples of peripheral blood from fasting children was obtained for hemoglobin counts, serum iron, and unsaturated iron binding capacity assays. information about the presence of diarrhea and/or fever during the 15 days preceding the study was also obtained. results: 35.8% (64/179) of the children presented iron deficiency and 75.4% (135/179), vitamin a deficiency. 29.1% (52/179) of the children presented both iron and vitamin a deficiencies. iron deficiency was not associated with vitamin a deficiency. a separate analysis for each hematimetric index also demonstrated no significant difference between children with or without vitamin a deficiency. children aged 24 to 36 months presented significantly higher prevalence rates of iron deficiency (p = 0.0005) as did children with diarrhea and/or fever during the 15 days preceding the study (p = 0.003). conclusions: although iron deficiency was not associated with vitamin a deficiency, high rates of both deficiencies were exhibited in a %26quot;healthy%26quot; population with low malnutrition indices. such situations are known as %26quot;hidden hunger%26quot;. younger children presented a higher risk of iron deficiency as did children with diarrhea and/or fever during the 15 days preceding the study.
