This randomized clinical trial evaluated the effects of iron supplements combined with malaria chemoprevention on cognitive outcomes in 6-month-old infants in rural Malawi. The study involved 2,168 infants and found no significant improvement in cognitive scores with iron interventions compared to malaria chemoprevention alone. The mean difference in cognitive scores was -0.52 for iron syrup and -0.85 for iron-containing powders.
Key findings
- No significant difference in cognitive scores with iron syrup (MD, -0.52) compared to malaria chemoprevention alone.
- Iron-containing micronutrient powders also showed no significant cognitive improvement (MD, -0.85).
- Both iron interventions increased ferritin concentration but did not reduce anemia prevalence.
- Malaria chemoprevention alone reduced malaria incidence compared to placebo.
Why it matters
The findings suggest that while iron supplementation may increase ferritin levels, it does not enhance cognitive outcomes in young children when combined with malaria prevention. This highlights the need for careful consideration of iron interventions in malaria-endemic regions.
