【 摘 要 】

The prevalence of hypovitaminosis A among children of the peripheral districts of the city of Campinas, São Paulo, Brazil, was estimated by determining serum retinol levels by High Performance Liquid Chromatography (HPLC) in a sample of 131 children aged between three and ten years, between April 1991 and February 1992. A prevalence of 17.6% and retinol concentrations in the range of 0.35 to 0.70 µmol/L were found (CI=11.1-24.1; 95%), indicating the existence of public health risk Ophthalmological examinations, however, failed to detect any cases of xerophthalmy. Additional characterization of the sample was obtained from 341 children. The per capita incorre of the average household was surprisingly high for low-income areas. According to FAO-WHO standards, food consumption was adequate only for protein (133.96%). Adequacy levels were low for energy (87.76%) and particularly for vitamin A (66.13%) and iron (42.14%). Height for-age and weight-for-height anthropometric indices revealed that many children were located below -1 standard deviation.
