Considerations for Correction of Micronutrient Deficiencies Through Supplementation in Pregnant Women and Children Under-5 in Latin America.

Background: Micronutrient deficiencies in Latin America are a public health concern, nonetheless, lack of information still exists in many countries, so that the true magnitude of the problem remains uncertain.

Objective: To summarise experiences that can inform the development of policies and programs to address micronutrient deficiencies throung supplementation in pregnant women and chlidren under five years of age in Latin American.

Methods: Review of the most evidence on the effects of micronutrients supplementation, focusing on pregnant women and children under five years of age.

Results: Certain population groups, as women of reproductive age and children under 2 years of age, are at increased risk for deficiency due to their high micronutrient requirements. This is compounded by the limited access to micronutrient-rich foods for many people living in vulnerable situations. Micronutrient supplementation is an effective intervention to prevent and treat deficiency and to mitigate its adverse effects on health, nutrition, and pregnancy outcomes in micronutrient-deficient populations. The potential benefits of supplementation programs, however, are realized only when they reach those who have the potential to benefit, that is, with inadequate intakes of micronutrients from dietary sources, and when the quality of design and delivery of the programs aresufficient to reach that population timely, regularly, and effectively to enable and motivate consumption.

Conclusions: Several resources and experiences exist that can help favor the development of programs that can realize this biological and programmatic potential. There is need for continuous efforts to augment coverage and achieve results that can translate into economic benefits for individuals, families, and nations.
