The 1997 Demographic and Health Survey in Mozambique shows that 47% of girls 15 to 19 years old living in Manica province (west-central Mozambique) are pregnant or have already had a child. A recent survey also shows that 45% of girls 10 to 18 years old attending school are anemic. Strategies are needed to build iron stores before pregnancy and to control seasonal and chronic iron deficiency and anemia in school-aged girls. ⋯ In Manica Province, school-based weekly IFA supplementation is a feasible and effective intervention to prevent seasonal drops in hemoglobin concentration and increases in anemia prevalence. Short supplementation periods can have an important impact on girls' hematological status. However, the size of girls' hematological response in this study was significantly lower that that observed in studies with similar population groups, initial anemia prevalence, supplement dosing, and/or supplementation regime.
