ABSTRACT
Background:
There is a correlation between aging and the decrease of plasma levels of vitamin B-12.Aim:
To determine the prevalence of vitamin B-12 and folate deficiency and its hematological impact among older adults (AM). Material andMethods:
Cross-sectional study, in 1028 subjects aged 65 to 87years, living in community and evaluated between 2005 and 2008. Percentile distribution of vitamin B-12, folate, hemoglobin, packed red cell volume and mean cell volume by gender and age were analyzed. Deficiency was defined as vitamin B-12 levels < 148 pmol/L, marginal deficiency as vitamin B-12 levels < 221 pmol/L, anemia was defined as a hemoglobin < 13 and 12 g/dL among men and women, respectively.Results:
The prevalence of vitamin B-12 deficiency was 12 percent and the figure for marginal deficiency was 25.4 percent. Males were more affected than females (p < 0.001). The frequency of anemia was 8.6 percento, and was higher among women (p = 0.004).Conclusions:
There is a high prevalence of full blown and marginal deficit of vitamin B-12 among the elderly. This deficiency should be considered for correction through public nutrition policies.Palavras-chave
