Trial using multiple micronutrient food supplement and its effect on cognition.

What Was Tested

Researchers studied Micronutrients in this randomized controlled trial publication.

Who Took Part

According to the abstract, 11 children were involved.

The age groups tagged for this paper are children, both men and women.

A battery of 7 memory tests (The personal information test, the Mann-Suiter Visual memory screen for objects, The digit span forward test, The digit span backward test, The delayed response test, The Benton Visual Retention Test and The Cattells retentivity test), one test for attention and concentration (Letter cancellation test) and one test for intelligence (Ravens's coloured progressive matrices) were administered to all the children at baseline and endline.

How the Study Was Run

The design is described as randomized.

Because people in this Micronutrients study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

The control group (N=72) consisted of day scholars who did not eat at the school.

What Was Measured

Topics PubMed links to this paper include Attention, Child Nutritional Physiological Phenomena, Cognition, Dietary Supplements, Erythrocyte Count, Food, Fortified and Hematocrit.

What This Means in Plain Language

The paper is a randomized study of Micronutrients in 11 children.

With fewer than 40 people, it is a small study, so it is better read as an early signal for further research than as a settled answer.

Its findings take up roughly 4 sentences of the abstract and are left out here on purpose; the source paper is the place to read them.

The publication is from 2008 (Indian journal of pediatrics), a journal based in India.
