This systematic review indicates that iron supplementation increases  Hb levels in children significantly but modestly .
The increase is greater in subjects who are anaemic at the start of the trial and lower in malarial hyperendemic areas and in those consuming iron-fortified food .
OBJECTIVE To evaluate the effect of iron supplementation on  haemoglobin ( Hb ) in children through a systematic review of r and omised controlled trials .
Preliminary findings on iron supplementation and learning achievement of rural Indonesian children.
The effects of oral iron supplementation on blood iron levels and learning achievement in 130 rural Indonesian school children were assessed in this double-blind study . The children were classified into anemic and nonanemic groups according to their initial hemoglobin and transferrin saturation levels and were r and omly assigned to either iron or placebo treatment for 3 mo . Hematological , anthropometric , and learning-achievement data were collected before ( T1 ) and after ( T2 ) the treatment period and 3 mo later . The means and st and ard deviations suggest that supplementation with 10 mg ferrous sulfate per kilogram body weight per day for 3 mo result ed in an apparent improvement in anemic subjects ' hematological status and learning-achievement scores . No tests of statistical comparisons are reported
