ABSTRACT
The distribution and magnitude of vitamin A deficiency and dietary consumption of 161 children at 6 to 72 months of age in rural zones in Cansancao-Bahia-Brazil were evaluated. The serum retinol levels were measured by the spectrophotometric method (Bassey-Lowry modified by Araujo and Flores). The serum retinol average was found to be distributed homogeneously throughout the different age groups. Inadequate serum retinol levels (<20,0 mu g/dl) were detected in 44.7% of the children, which characterized the deficiency as constituting a public health problem. The serum retinol levels showed no statistically significant association as between the sex and age of the children; however the children of less than 24 months showed a higher prevalence of inadequate serum retinol levels. The main available source of vitamin A for these children was represented by carotenoids, especially beta-carotene. Foods regarded as being rich in vitamin A were consumed by all age groups. The greatest diversification of consumption of foodstuffs with moderate and low vitamin A content was observed in the group of children of from 24 to 72 months of age, through this was no guarantee of adequate serum retinol levels in this group however.
