Resumen

YENEISY, Lanyau et al. Estado nutricional y vitaminas B1 y B2 en ancianos no institucionalizados. Rev Cubana Salud Pública [online]. 2003, vol.29, n.3, pp.209-214. ISSN 0864-3466.

In order to know the nutritional status of vitamins B1 and B2 in non-institutionalized elderly, 50 indivudals over 60 from 2 health areas of Centro Habana municipality were studied. The levels of vitamins B1 and B2 were determined by the techniques of stimulation of erythrocytary transcetolasa and gluthatione reductase. Body weight and the shoulder-elbow and knee-heel distances were measured to evaluate the body mass index (BMI). The ingestion of these vitamins was estimated through a quantitative survey by a 3-day food registry in a subsample of 21 aged people. The toxic habits and the use of vitamin supplements were investigated. It was found that 65 and 64 % of the elderly had defficient and suboptimal levels of B1 and B2, respectively. Approximately 40 % of the elderly did not fulfill 50 % of the daily diet recommendations for both vitamins. No significant differences were found between the levels of vitamin in boths sexes. At about 60 % had an adequate BMI. BMI was markedly higher in women. Those over 80 had a significantly lower BMI . There was no association between the BMI and the suboptimal levels of vitamins.The levels of vitamins did not change in relation to smoking habit and the consumption of alcoholic beverages. Only 36 % of the elderly had vitamins as a diet supplement. The number of individuals with vitamin B1 and B2 deficiency was higher in the non-consumer group. These results showed the need to improve the nutritional status of these vitamins in this population group
