    Article - En anglais

    A study ofthe nutritional status of beta-carotene and retinol of 228 institutionalized elderly individuals, in four elderly homes of Mexico City was carried out.

    Subjects varied between 61 and 101 years of age (151 were females and 77 were males).

    High pressure liquid chromatography was used to quantitate retinol and beta-carotene.

    Ninety eight percent of elderly individuals showed bêta-carotene levels less than acceptable (at risk) ; 85.2% were deficient (high risk), and 12.9% were low (medium risk), only 1.85% had acceptable values (low risk).

    Ninety two percent of subjects had acceptable values (low risk) of retinol, while 6.0% and 2.0% were low (medium risk) and deficient (high risk) respectively.

    There were not significant differences among the four elderly homes.

    No significant correlation with age was found for any of the two vitamins.

    No sex related difference (p>0.05) was observed in serum vitamin A and bêtacarotene in either group.
