  1. Fulltext. Chronic low intakes of vitamin A-rich foods in households with xerophthalmic children : a case-control study in Nepal.

    Article - En anglais

    Fulltext.

    Dietary patterns in 81 rural Nepali households with a 1-6-y-old child with a history of xerophthalmia were compared with dietary patterns of 81 households with an age-matched nonxerophthalmic control subject.

    Weekly food-frequency questionnaires were collected from case and control « focus » children, a younger sibling (if present), and the household 1-2 y after recruitment and treatment of cases.

    Control households and children were more likely than case households and children to consume vitamin A-rich foods during the monsoon (July-September) and major rice harvesting (October-December) seasons.

    Cases were less likely to consume preformed vitamin A-rich foods throughout the year [odds ratio (OR)=1.2-4.5] with the strongest differences observed from October to December (OR=2.0-4.2).

    Dietary risks were generally shared by younger siblings of cases, suggesting that infrequent intake of bêta-carotene and preformed vitamin-A rich foods begins early in life and clusters among siblings within households, a pattern that is consistent with their higher risk of xerophthalmia and mortality.

    In developing countries where vitamin A deficiency is endemic, dietary counseling for children with xerophthalmia should be extended to their younger siblings.

    Moreover, dietary intake of preformed vitamin A may be as, or more, important as carotenoid-containing food consumption in protecting children and other members of households from vitamin A deficiency.
