Efficacy of twice weekly iron supplementation in anemic adolescent girls.

Two hundred and forty four girls with different hemoglobin levels were selected, of which forty-one were non-anemic. The rest were graded as mildly, moderately or severely anemic and supplemented with 60 mg of iron daily or twice weekly for twelve weeks. There was no significant difference in the increase in hemoglobin levels between daily and twice weekly-supplemented subjects at the end of the study. Unpleasant side effects of supplementation were experienced by 57.8% of the daily supplemented subjects as against 5.9% of twice weekly-supplemented ones. Twice weekly supplementation could be recommended for overcoming anemia in adolescent girls.
