A study of iron deficiency anaemia in preterm babies and the effects of prophylactic iron.
Abstract
This study was undertaken to determine the haemoglobin levels at birth, the frequency of iron deficiency anaemia and the value of prophylactic iron in its prevention in preterm infants. At the start of the study there were 123
preterm infants weighing between lOOOgms and 2000gms, the
. ...
mean birth weight being l474gm(SD~269). The mean haemoglobin
level at birth for 112 preterms whose haemoglobin results were obtained was 16.2gm/dl (3D!2.5) with a range from lO.lgm/dl
to 21.1gm/dl. There was no difference in haemoglobin levels
at birth between birth weights of IOOOgm and 2000gms correspoding to 28 and 34 weeks ~f gestation. Initially there were 63
cases in the study group and 60 cases in the control group.
At the end of 6 ~onths of follow up there were 19 cases in the treatment group and 8 cases in the control group.
The treatment group was giv~n ferrous sulphate solutio~
at a dose providing 2mg. eJemental iron/kg body weight/day

test could not be done. However, infants in the treatment group had sliBhtly higher haemoglobin levels, MCV and
MCR compared to the control group, and they also had fewer cases of iron deficiency anaemia. The frequency of iron
deficiency anaemia at 6 months was 7% in the treatment group
compared to.71% in the control group. The value of prophylactic iron in prevention of iron deficiency anaemia
could not be definitely verified by the results of this study.
