F. Guidozzi et al., A PROSPECTIVE-STUDY OF IRON STATUS IN WHITE AND BLACK PREGNANT-WOMEN IN AN URBAN HOSPITAL, South African medical journal, 85(3), 1995, pp. 170-173
Evaluation of the iron status (haemoglobin and ferritin concentrations
, and percentage transferrin saturation) in a prospective study of 65
pregnant women (55 white and 10 black) revealed that adequate maternal
iron stores during pregnancy cannot be maintained with prevailing die
tary patterns. Although 80,6% of the patients had normal indices in th
e first trimester, only 12,3% were normal in the third. Significant de
pletion of iron stores occurred in the second trimester, but significa
nt iron-deficient erythropoiesis only occurred in the third trimester,
Despite the decline in iron status, iron deficiency anaemia was only
seen in 7 - 8% of the patients, Even after correction for the haemodil
ution and increased transferrin concentrations in pregnancy, over 70%
of women had depleted iron stores in the third trimester. No beneficia
l effect on fetal birth weights was found on withholding of maternal i
ron supplementation. This study clearly demonstrated that white and ur
ban black pregnant women require iron prophylaxis to maintain iron sto
res.
