Randomized Controlled Trial Clinical Trial
Effectiveness of weekly vitamin A (10,000 IU) and iron (60 mg) supplementation for adolescent boys and girls through schools in rural and urban East Java, Indonesia.
High prevalences of vitamin A deficiency and anaemia among adolescents warrant interventions. This study evaluated the effectiveness of school-based supplementation to reduce anaemia and improve vitamin A status. ⋯ Supplementation with vitamin A increased serum retinol concentration of boys. Iron supplementation did not change Hb. This appeared to be due to poor compliance, and partly related to side effects.
