BACKGROUND: Weekly iron-folic acid supplementation in small-scale research trials and as administered in institutions has been demonstrated to be effective in reducing anemia in adolescent girls. OBJECTIVE: To assess the effectiveness of weekly iron-folic acid supplementation in a large-scale project in reducing the prevalence of anemia in adolescent girls. METHODS: The project provided weekly iron-folic acid tablets, family life education, and deworming tablets every 6 months to 150, 700 adolescent school girls and non-schoolgirls of a total district population of 3, 647, 834. Consumption of the iron-folic acid tablets was supervised for schoolgirls but not for non-schoolgirls. Hemoglobin levels were assessed in a random sample of non-schoolgirls at 6 and 12 months and schoolgirls at 6 months. The effect of supplementation on the prevalence of anemia and the compliance rate were assessed over a 4-year period. RESULTS: In 4 years, the overall prevalence of anemia was reduced from 73. 3% to 25. 4%. Hemoglobin levels and anemia prevalence were influenced significantly at 6 months. No difference in the impact on hemoglobin or anemia prevalence was observed between supervised and unsupervised girls. Counseling on the positive effects of regular weekly iron-folic acid intake contributed to a high compliance rate of over 85%. The cost of implementation was US0. 36 per beneficiary per year. CONCLUSIONS: Weekly iron-folic acid supplementation combined with monthly education sessions and deworming every 6 months is cost-effective in reducing the prevalence of anemia in adolescent girls. Appropriate counseling, irrespective of supervision, is critical for achieving positive outcomes.
