Randomized Controlled Trial Comparative Study Clinical Trial
Effect of daily and weekly micronutrient supplementation on micronutrient deficiencies and growth in young Vietnamese children.
Micronutrient deficiencies remain common in preschool children in developing countries. Interventions focus on single micronutrients and often lack effectiveness. Weekly instead of daily supplementation may improve effectiveness. ⋯ Weekly and daily supplementation improved hemoglobin, zinc, and retinol concentrations similarly. Neither intervention affected growth of the overall population, but growth of children stunted at baseline was improved through both types of supplementation.
