Implication

Cluster-randomized trial reveals no major cognitive gains, but higher Kiswahili scores with MMNS in schoolchildren.

Key Points

  • No significant cognitive improvement was observed from physical activity or supplementation interventions.
  • The MMNS groups showed significantly higher Kiswahili scores compared to the placebo group.
  • Children were assessed over two school years using various cognitive and academic performance tests.
  • Further research is needed to refine school-based nutrition and activity initiatives for enhanced learning outcomes.
