Folic acid and ascorbic acid status have been assessed in
twenty non-institutionalized elderly subjects with respect to both
hematological and dietary aspects.
The hemoglobins, hematocrits, and serum ascorbic acid
concentrations were within the normal range. A few subjects had
total serum protein concentrations which were less than the acceptable
level. More than half of the subjects had serum folic acid
concentrations below the acceptable level. Mean dietary nutrient
intakes were comparable to the Recommended Dietary Allowances
with the exception of calories and folic acid.
In general, the diets of the men were higher in calories,
protein and iron while diets of the women were higher in ascorbic
and folic acids. The men tended to have higher hematocrits,
hemoglobin and serum folates while the women had higher serum concentrations of ascorbic acid. No significant effect due to vitamin
C supplementation was observed. Although there was no significant
correlation between the serum concentrations of ascorbic and folic
acids, examinations of group means suggested that these parameters
were inversely related.
Multiple regression analyses of hematological values and
dietary nutrient intakes revealed no significant effects. / Graduation date: 1975
