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 .
Iron supplementation and physical growth of rural Indonesian children.
The effect of oral iron supplementation on blood Fe levels and physical growth in 119 rural Indonesian school children was assessed in this double-blind study . The children were classified into anemic and normal groups according to their initial hemoglobin and transferrin saturation levels and were r and omly assigned to either Fe or placebo treatment for 12 wk . Hematological , anthropometric , and morbidity data were collected before and after the treatment period . Before treatment , anemic subjects were smaller and had higher morbidity than normal subjects . Treatment with 10 mg ferrous sulfate.kg-1.d-1 for 12 wk result ed in a significant improvement in anemic subjects ' hematological status , growth velocity , and level or morbidity
