SETTING: Government girl schools of northeast Delhi. SUBJECTS: 2088 subjects (with hemoglobin greater than 7.9 g/dL), including 702 on daily and 695 on weekly iron-folate administration; 691 girls served as controls. RESULTS: About 85% girls were iron deficient out of which 49.3% were anemic. Weekly administration took longer time to raise hemoglobin but was effective as well as practical.
