Multiple micronutrient supplementation (MMS) during pregnancy is a cost-effective intervention to reduce these adverse outcomes. However, important knowledge gaps remain in the implementation of MMS interventions. The Child Health and Nutrition Research Initiative (CHNRI) methodology was applied to inform the direction of research and investments needed to support the implementation of MMS interventions for pregnant women in low- and middleincome countries (LMIC). Following CHNRImethodology guidelines, a group of international experts in nutrition andmaternal health provided and ranked the research questions thatmost urgently need to be resolved for prenatal MMS interventions to be successfully implemented. Seventy-three research questions were received, analyzed, and reorganized, resulting in 35 consolidated research questions. These were scored against four criteria, yielding a priority ranking where the top 10 research options focused on strategies to increase antenatal care attendance and MMSadherence, methods needed to identify populationsmore likely to benefit fromMMS interventions and some discovery issues (e.g., potential benefit of extending MMS through lactation). This exercise prioritized 35 discrete research questions that merit serious consideration for the potential of MMS during pregnancy to be optimized in LMIC.enpregnancymicronutrientssupplementationresearch prioritieslow- and middle-income countriesSetting research priorities on multiple micronutrient supplementation in pregnancyArticle
