Abstract
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 US$0.36 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.
