Abstract:
Iron deficiency (either clinical or subclinical) may occur in geriatric
subjects as result of decreased dietary intake, malabsorption or other factors such
as chronic blood loss from the gastro intestinal tract. This report deals with a study
of the effects of iron supplementation in an instututionalised geriatric population.
Forty nine inmates (28 males, 21 females) of a home for the aged were selected at
random (mean age 74.59±7.56 years).Biochemical, haematological and clinical
assessment of iron status was carried out prior to supplementation. All subjects
were given nutroferol plus (250mg, twice daily) and the iron status was reassessed
one week, six weeks and twelve weeks after commencement of supplemental
therapy. Twenty seven subjects had haemoglobin concentrations below 12g%
(group1), while twenty two subjects had haemoglobin concentrations greater than
12g%(Group II). A highly significant increase in transferin saturation (p<0.001)
occurred in subjets belonging to group I by the end of six weeks. Continuation of
therapy for a further period of six weeks (i.e. twelve weeks) did not cause a
significant increase in transferin saturation as compared to the value at the end of
six weeks. The rise in transferrin saturation was smaller, but significant (p<0.01)in
subjects belonging to group II. Haemoglobin concentration showed a significant
increase (p<0.05)only in subjects belonging to group I. Our studies show that iron
supplementation was beneficial in improving the iron status, specially in subjects
with a haemoglobin concentration of less than 12%. Supplementation for period
of six weeks was sufficient to improve the iron status.
