title: [Effect of multi-micronutrients supplementation on memory ability of schoolchildren].
abstract: 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.
  
  
  CONCLUSIONS
  It was seemed that multi-micronutrients supplement could improve memory ability of schoolchildren.
