There is a need to better understand the coverage of scaled-up multimicronutrient supplementation programs.The coverage of the distribution of multimicronutrient supplements in 26 urban communities among women and adolescent girls 12 through 44 years of age and children under 5 years of age was evaluated for purposes of scaling-up.Formative research and descriptive statistics were used to analyze the distribution of supplements.Despite a delayed memorandum of understanding with the health sector and delayed delivery by the producer of the supplement, a high coverage rate of supplement distribution to the children (88% on average during the 3 months of supplementation) was still achieved as a result of the strong commitment of the community and the Integrated Food Security Program. The lower coverage rate among women and adolescent girls (47% on average) was the result of too short a period of enrollment in the program. There was no decrease of coverage during the 3 months of supplementation in both groups.Effective, sustainable, large-scale micronutrient supplementation programs require broad partnerships with commitments of governmental and nongovernmental organizations, communities, and the private sector. Availability of the supplements and communication materials must be secured well ahead of the supplementation campaign and distribution of the supplement.
