Iron or Multiple Micronutrient Powder Supplements With Malaria Chemoprevention in Rural Malawian Children: The IRMA Randomized Clinical Trial.

Universal iron or micronutrient powder supplements with malaria chemoprevention did not improve cognitive outcomes in Malawian children aged 6 to 18 months.

• Why it matters: Addressing anemia in young children is crucial for neurodevelopment, but the safety and effectiveness of iron interventions in malaria-endemic areas remain uncertain, creating a gap in evidence-based guidelines.
• What they did: The IRMA trial randomized 2,168 infants to receive iron syrup, micronutrient powders, malaria chemoprevention alone, or placebo, assessing cognitive, language, motor outcomes, anemia, and infection risk over 12 months.
• The result: Neither iron interventions enhanced cognitive scores nor reduced anemia prevalence, and they did not increase malaria risk; malaria chemoprevention alone effectively reduced malaria incidence.
