A WHO collaborative study on iron supplementation in Burma and in Thailand

Abstract

Studies on the treatment and prevention of iron deficiency anemia, in pregnant and nonpregnant women and in men, were conducted in Thailand and Burma. The effects of the dose of Fe, duration of Fe administration, additional supplementation with folate, mode of supplement delivery (either supervised or unsupervised), and the presence of Hb(AE) were studied. The frequency and severity of side effects were also recorded. Fe administration resulted in an increase in hemoglobin concentration in all anemic individuals but ~20% failed to reach normality. The length of administration and the dose influenced the results. Frequency and severity of side effects increased with the dose of Fe administered. Folate supplementation did not affect the results. It appears possible to integrate a program of prevention and treatment of Fe deficiency anemia in a primary health-care system but the constraints and limitations of achievable results should be recognized.
