Objective:
To study the effect of multi-micronutrients on memory ability of school children.
Methods:
In this double-blind and placebo-controlled test, the children aged 9 to 11 years, in the forth grade from two primary school in Sichuan Province, were recruited after health examination. A total of 275 children were randomly designed by the whole class as the test group taken multi-micronutrient supplement and the control group given with placebo for 4 months. Memory quotient, intelligence, average reaction time of children in two clusters were assessed before and after supplementation.
Results:
The mean scores of the memory quotients and the Wechsler Memory Scale scores (Digit summation\ Visual Reproduction\ touch memory) of multi-micronutrients group were significantly higher (P < 0.05) than those of control group. The mean incremental scores of the memory quotients of the rural test group were significantly higher (P < 0.05) than those of the rural control group. There was no significant difference between the test group and control group in intelligence.
Conclusion:
It was seemed that multi-micronutrients supplement could improve memory ability of schoolchildren.
