ABSTRACT
It has been reported that large numbers of elderly Americans are moderately anemic because of iron deficiency anemia. In the present study, information has been obtained concerning blood composition, health, and nutritional habits of 779 people over 60 years of age, institutionalized or free-living in the Boston area. This paper presents the results of their blood examinations. Two hundred twenty-one of the free-living people examined who showed hemoglobin levels between 9 and 12.9 g/dl agreed to participate in an iron fortification study. Two-thirds of them received iron-fortified grain products daily for 6 to 8 months. The rest received the same foods without added iron. At the end of the experimental period a marked increase in hemoglobin levels averaging 1.4 g/dl was observed in both groups. This appeared to be attributable to an undefined intervention effect; no measurable effects attributable to the iron fortification were observed. Three months of daily ferrous sulfate administration to those whose hemoglobin levels remained below 13 g/dl was without effect. Examination of the data obtained suggests that the cause of the moderately low hemoglobin levels initially observed was not occult bleeding or folic acid or iron deficiency.
