Micronutrient Enhancement for Development and Health in Adolescents - The MEDHA Study

MEDHA is a randomized controlled trial among 10-18 year old girls to examine the use-case of the United Nations International Multiple Micronutrient Antenatal Preparation (UNIMMAP) multiple micronutrient supplement (MMS) formulation and to test an enhanced regimen (MMS+) with additional nutrients, vs. weekly iron-folic acid as standard of care on outcomes of neurodevelopment, linear growth, biochemical status, bone health, and other functional and health outcomes. This study is an individually randomized, open-label, three-arm trial of 3,000 participants supplemented for 12 months to assess the efficacy and safety of nutrient supplementation. Results of the study will inform the design of nutritional interventions and policy for this age group. In the context of the trial, the investigators will also do in-depth clinical and health assessments and collect biospecimens for a bio-archive for future deep-phenotyping of this population. This study will be conducted at the Johns Hopkins Bangladesh JiVitA field site in rural Gaibandha District of Bangladesh.
