Abstract:
Before and after zinc and micro-nutrients supplement the changes of intelligence and growth in 108 healthy children aged 7～8yrs were studied.The children were randomly divided into 3 groups:zinc supplement(Z),zinc+micronutrients supplement(Z+M),and micronutrients supplement(M),Before the supplements,hair Zn contemt of children was 2 28?0 74?mol/g and 22 22% of the hair Zn content was lower than 1 68?mol/g?There was a positive correlation between intelligence quotient(IQ) and hair Zn content .After supplement,there were no significant changes among the 3 groups on hair Zn content .The changes of IQ and cognition in Z+M group and M group were significantly higher than Z group,and there was no significant difference between Z+M group and M group.The change of knee height in Z+M group was markedly higher than M group and Z group,while M group was sgnificantly higher than Z group.The results demonstrated that zinc deficiency might not be the main factor that affects the intelligence and growth children,perhaps other micronutrients deficiency should be paid more attention.The simultaneous supplement of zinc and micronutrients may promote the intelligence and growth of children.
