Maternal multi-micronutrient (MMN) supplementation during pregnancy could drastically improve cognitive ability in children, reports a study published on 17th January in The Lancet Global Health. This may be apparent in children between the ages of 9 to 12 years.
The Summit Institute of Development research team led a follow-up study involving 2,879 schoolchildren in Indonesia whose mothers were supplemented with MMN or iron + folic acid (IFA) in the Supplementation with Multiple Micronutrients Intervention Trial (2001-2004).
SID’s initial research was conducted with 31,290 pregnant women on Lombok Island. The women were selected randomly to receive multi-micronutrient supplements.
The CEO of SID, Mandri Apriatni, commented: “Results of our initial research showed there had been an 18 percent decrease in infant mortality rates each year among mothers who had taken multi-micronutrient supplements during their pregnancy, much lower compared to those who only received iron and folate acid supplementation.”
In the follow up-study that saw children complete cognitive tests over a two-year period, researchers observed better procedural memory in MMN children vs IFA children. The difference between the two corresponded with the increase associated with an additional half-year of schooling.
Children of anaemic mothers in the MMN group scored considerably higher in general intellectual competence, equivalent to the increase associated with an additional full year of schooling. Overall, there was a positive coefficient of MMN vs IFA in 18 / 21 tests.
