“…In a previous paper (8) we described associations between the prevalence of night blindness and socio-demographic variables as well as with dietary practices and intake of vitamin A capsules in a population of rural children in northern Bangladesh. This finding was in agreement with other studies in Bangladesh and elsewhere (4,9,12). However, studies showing the associations between vitamin A status and socio-economic, demographic and dietary characteristics are uncommon.…”

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.

“…In developing countries where protein-energy malnutrition is highly prevalent, children usually have multiple micronutrient deficiencies, particularly of zinc (28,29) and vitamin A (30). Reports from Bangladesh showed that > 60% of children remain vitamin A deficient despite supplementation with large doses of vitamin A (31)(32)(33).…”

Background: Zinc deficiency limits the bioavailability of vitamin A. Because zinc and vitamin A deficiency often coexist in malnourished children, simultaneous zinc and vitamin A supplementation may improve the vitamin A deficiency in these children. Objective: A randomized, double-blind, placebo-controlled intervention trial was conducted to evaluate whether combining zinc and vitamin A supplementation would improve the biochemical indexes of vitamin A nutriture. Design: Children aged 12-35 mo were randomly assigned to 1 of 4 intervention groups: 20 mg Zn/d for 14 d (Z group), 60 000 retinol equivalents (200 000 IU) vitamin A on day 14 (A group), zinc plus vitamin A (ZA group), or placebo syrup and placebo capsule (placebo group). Venous blood was drawn at enrollment and on day 21. Results: Mean serum retinol concentrations were not significantly different between the A and ZA groups. Among vitamin A-deficient children, the proportion of children who remained vitamin A deficient (serum retinol < 0.7 mol/L) after supplementation was 40.6% in the Z group, 37.5% in the A group, and 47.0% in the placebo group; only 13.3% in the ZA group remained vitamin A deficient (P < 0.05 compared with the placebo group). The proportion of children whose retinol binding protein concentrations remained low was significantly lower in the ZA group than in the other groups (P < 0.05). Conclusion: Combined zinc and vitamin A supplementation improves vitamin A nutriture in vitamin A-deficient children.

“…In the set of earlier studies, home gardens were positively associated with a decreased risk of vitamin A deficiency (Cohen et al 1985) and reduced clinical eye signs of vitamin A deficiency (Solon et al 1979). Gillespie and Mason (1994) also concluded from their review that there was evidence that food-based approaches could be effective in the control of vitamin A deficiency.…”

This chapter reviews current knowledge and experience with using food-based approaches in reducing vitamin A and iron deficiencies. It reviews recently published literature, highlights some lessons learned, and identifies knowledge gaps and research priorities. The main strategies reviewed are food-based interventions that aim at: (1) increasing the production, availability, and access to vitamin A and iron-rich foods through the promotion of home production and (2) plant breeding strategies that have the potential to increase the content of vitamin A and iron in diet as well as their bioavailability. The review highlights the fact that significant progress has been achieved in the past few decades in the design and implementation of food-based approaches. Evaluations however remain weak, and without rigorous, carefully conducted evaluations the real potential of food-based approaches in addressing micronutrient malnutrition cannot be fully understood. Plant breeding strategies, although they are at a much earlier stage of development, hold great promise M. T. Ruel is affiliated with the International Food
