Iron supplementation: country level experiences and lessons learned.

Iron supplementation is a commonly used strategy to meet the increased requirements of at-risk groups, such as women of childbearing age, especially during pregnancy. Other at-risk groups for which iron supplementation may be appropriate include infants, young children, adolescents and the elderly. There is a need to consider iron supplementation as part of a comprehensive strategy for the prevention of iron deficiency, and not just as a treatment for anemia that is stopped as soon as clinical improvement is noted. Experience in developing countries indicates that often the poorest women with the most deficient intakes are the least likely to receive iron supplements during pregnancy. Providing supplements to women during antenatal care visits is useful but often inadequate, so other delivery channels must also be explored, including private sector markets and community networks. Communication efforts must be expanded to increase understanding of the importance of taking supplements and to address any fears or misconceptions relating to supplementation. Overall, we must increase the capacity of individuals and communities to define, analyze and act to address their own health needs.
