    Author: Hussain A, Kvăle G.
    Journal: Acta Paediatr; 1996 Aug; 85(8):971-6. PubMed ID: 8863881.
    Abstract:
    The purpose of this study was to examine socio-economic conditions, demographic factors, use of vitamin A capsules and dietary practices in relation to the risk of low serum vitamin A. One hundred and twenty four night blind cases were identified by parents in a cross-sectional survey in Bangladesh in 1992. Age-, sex- and neighbourhood-matched controls were selected. Venous blood was collected from 87 cases and 97 controls for the determination of serum vitamin A. Information about socio-economic conditions, demographic factors, use of vitamin A capsules and dietary practices was obtained by interview. The level of serum vitamin A was strongly related to age and consumption of beta-carotene rich foods. The preschool years (2-6 years) are important risk periods for vitamin A deficiency among children. We conclude that long-term prevention of vitamin A deficiency should rely on efforts to improve local diet.
