Title: Community-based Intervention Trial to Compare the Impact of Preventive and Therapeutic Zinc Supplementation Programs Among Young Children in Burkina Faso
Brief Summary: Zinc supplementation can either be provided in a lower daily dose to prevent zinc deficiency or in a higher dose for 10-14 days as part of the treatment of diarrhea. It is important to determine how best to integrate programs designed either to prevent zinc deficiency or to treat diarrhea.

The overall objective of this project is to determine the most effective approach to prevent zinc deficiency and treat diarrhea, such that a single approach could provide the maximal beneficial impact on the health and nutritional status of young children and greatest simplicity of implementation.
