Descripción detallada
Adolescents (10-19 year olds) are an understudied group despite increasing numbers in many regions, especially in low- and middle-income countries (LMICs). Numerous reviews on adolescent health and nutrition have identified major data gaps for this population, including lack of information on the nutritional challenges and the burden of existing deficiencies adolescents face and uncertainty about the level of nutritional support required during this period of rapid physical and cognitive development during and following puberty. The consequences of poor adolescent nutrition for reproductive health and survival as well as bone health in later life among females calls for special attention to vulnerable girls in LMICs.
The primary aim of this study is to determine the efficacy of daily supplementation with MMS (using the UNIMMAP formulation) and an enhanced regimen (MMS+) composed of UNIMMAP plus additional nutrients (calcium, choline, docosahexaenoic acid -DHA, and higher amount of vitamin D) vs. weekly iron-folic acid (IFA) alone on a range of neurodevelopment, biochemical, linear growth and functional outcomes among 10-18 year old girls in rural Bangladesh. The investigators hypothesize that daily MMS or MMS+ will result in an improvement for the co-primary outcomes of school achievement and physical growth (HAZ), and secondary functional outcomes including neurocognitive function, bone health, and biochemical nutrient status among adolescents following 6 and 12 months of supplementation compared with weekly IFA supplementation.
