Quantitative relations between baseline iron status , study duration , and iron dose on changes in iron-status biomarkers , which were generated from the meta-analyses , can be used to predict effects of trials of iron supplementation and fortification and to design iron-intervention programs
BACKGROUND The response of status biomarkers to an increase in iron supply depends on several physiologic and environmental factors , which make it difficult to predict the outcome of an intervention .
OBJECTIVE We assessed effects of baseline iron status , sex , menopausal status , duration of intervention , iron form , and daily dose on the change in iron status in response to iron supplementation .
Iron fortification of domestic drinking water to prevent anemia among low socioeconomic families in Brazil.
Iron deficiency anaemia is a most common micronutrient deficiency affecting mostly the low socioeconomic population s of the developing world . The objective of this study was to evaluate the feasibility of iron fortification of household drinking water to prevent iron deficiency anaemia among members of the low socioeconomic families of Southern Brazil . A total of 21 low socioeconomic families representing 88 subjects including 1 - 6 years old children whose haemoglobin level was between 10 and 12 g/dl were selected to participate in this study . Nine families in the control group were supplied with placebo solution and 12 families in the experimental group were supplied iron solution with ascorbic acid to be added to their domestic drinking water over a period of 4 months . The feasibility and acceptability of iron fortified drinking water was assessed through home visits and question naires . Blood sample s were collected at the beginning and after 4 months of the study for the determination of haemoglobin and serum ferritin levels . The results of this study indicated that iron fortified drinking water was well received by the low socioeconomic families and that it was effective in improving the haemoglobin and serum ferritin levels . It can be concluded from this study that iron fortification of household drinking water is a simple and effective alternative for developing countries along with other technological approaches to iron fortification of foods
