Erythrocyte folate levels in young and old.
Erythrocyte folate levels were compared among 25 young healthy subjects (mean age, 27 years), 29 healthy subjects aged over 75 living in the community, 62 subjects (mean age, 75) admitted to a geriatric assessment ward (acute illnesses), and 32 subjects (aged over 65) in a ward for long-term physical or mental illnesses. Overall, the female/male sex ratio varied from 2:1 to 3:1. For the three elderly groups, the incidence of low erythrocyte folate levels (less than 100 mmicrogram/100 ml) were 24 percent, 16 percent, and 18 percent, respectively. For the young group, the mean value would be over 296 mmicrogram/100 ml. Dietary folate deficiency may often account for low folate blood levels in the elderly, but other factors should also be implicated, e.g., the ability to absorb folate.[1]References
