Introduction. Vitamin A is very important in its nutritional role and is a critical factor in childhood health and survival. Objective. The objective of this work was to evaluate vitamin A levels in children coming from families with low socioeconomic status (LSS) from three areas of the country and to determine the relations that could exist among those levels and certain clinical anthropometric, alimentary and socioeconomical variables. Population. All the children from 0.5 to 2.11 years-old from families with LSS who attended, to determined health centers for control with the physicians involved in this study from September to December 1995. Exclusion criteria were the children with chronic or present diseases, but not the undernourished ones. In Buenos Aires 268 children were studied, in Chaco 140, and 195 in Corrientes. Material & methods. The physician in each health center accomplished the following: Information collecting by means of: A) a questionnaire with personal data, nutritional and pathological history and immunizations. B) Clinical and anthropometric evaluation, and blood samples of each child for plasmatic retinol dosage in accordance with standardized techniques. Retinol normal lower limit was set up in 20 µg/dl. Results. High prevalence of A vitamin deficit was found in studied samples: 26%, 32% and 46% of studied children in Buenos Aires, Chaco and Corrientes, respectively. Correlations among retinol and socioeconomic, morbidity and nutritional variables were not found. Conclusions. Results on 603 studied children between 0.5 and 2.11 years-old belonging to families with LSS in three studied areas in Buenos Aires, Chaco and Corrientes, revealed severe vitamin A deficit
