: Forty-nine rural primary schools took part in the study and
were randomly assigned to two groups: children in 25 schools
received a weekly tablet providing 108 mg iron while children in
24 schools acted as controls. All children were dewormed before
the start of the iron supplementation. The haemoglobin
concentration of a systematic sample of one in three children in
two classes in each school was estimated before and 5–17 weeks
after the end of the iron supplementation. Results : A total of
1510 children aged 7–12 years were studied at both surveys. The
mean haemoglobin concentration of children
