MATERIAL AND METHODS Mean daily consumption of iron, folic acid and vitamin B(12) were determined for each patient by means of dietary analysis of food registries, followed by evaluation of free serum cobalamin and homocysteine. Anemia diagnosis was established by quantification of total hemoglobin. RESULTS Prevalence was found to assault 9.8% of elderly studied. No significant difference has been observed in folic acid and iron intakes between anemic and non-anemic subjects. On the other hand, mean consumption of vitamin B(12) was 2.6 times higher among anemic patients (p < 0.05). Accordingly, serum cobalamin and homocysteine dosages have shown marked increase in the anemic group. CONCLUSIONS Our findings suggest that deficiency in vitamin B(1...

Material e Métodos: Para cada paciente, foi determinada a média da ingestão diária de ferro, vitamina B 12 e ácido fólico por meio da análise dietética dos registros alimentares estimados de três dias alternados, seguida pela determinação das dosagens séricas de cobalamina livre e homocisteína. O diagnóstico de anemia foi estabelecido pela dosagem de hemoglobina total. Resultados: Encontrou-se uma prevalência de anemia em 9,8% das idosas estudadas. Não foi observada diferença significativa no consumo de ferro e ácido fólico entre pacientes anêmicas e não-anêmicas. No entanto, o consumo médio de vitamina B 12 entre as pacientes não-anêmicas mostrou-se 2,6 vezes superior à ingestão média observada no grupo anêmico (p < 0,05). Dosagens séricas de cobalamina e homocisteína mostraram-se aumentadas entre portadoras de anemia. Conclusões: Nossos dados sugerem que a deficiência na ingestão de vitamina B 12 constitui fator predisponente ao desenvolvimento de anemia em pacientes idosos.

Conclusions: Our findings suggest that deficiency in vitamin B 12 intake constitutes a predisposing factor to the onset of anemia in the elderly.
