The vitamin A deficiency (VAD) is considered as a major public health problem in the world. This phenomenon is still not well known in Algeria. The prevalence of this deficiency is calculated on a group of children in good health, not supplemented with vitamin A, from rural, semi-rural and urban environments in the Blida region (Algeria), aged 1 to 23 months and recruited in the pediatric services of Blida area, during the period of November 2007-April 2008. The sample is composed of 150 children (87 boys and 63 girls) who present a concentration of C-reactive protein (CRP) < 10 mg/L. The mean concentrations of serum retinol are 1.049 卤 0.422 渭mol/L. The dosages of the serum retinol-binding protein (RBP) and prealbumin revealed the mean values of 0.024 卤 0.009 g/L and of 0.152 卤 0.039 g/L, respectively for RBP and prealbumin. The prevalence of serum retinol deficiency is 19%; this indicates the presence of a moderate VAD. The prevalence of carrier protein deficiency is 76% for the RBP and 10% for the prealbumin. To remedy the problem of vitamin A deficiency, it is advisable to implement a policy of nutritional education. The supplementation can be interesting only for the children whose nutritional status is defective or living in areas where the food products rich in vitamin A are rare.
