目的:探讨锌和微量营养素与儿童智能和生长发育的相关性。方法:选择430例受试儿童随机分为两组,观察组210例,补充锌和微量营养素;对照组220例,未补充锌和微量营养素。比较两组儿童受试前、后认知功能、智商以及膝高3项指标变化差异。结果:两组儿童受试后认知功能、智商均强于受试前,膝高也比受试前有所增加,但观察组认知功能、智商以及膝高的变化幅度大于对照组,两组变化幅度比较差异有统计学意义(P<0.05)。结论:锌和微量营养素对儿童智能和生长发育有着十分重要的作用,在儿童生长发育过程中,应适当的对儿童补充锌和微量营养素,以促进儿童茁壮成长。 Objective: To explore the correlation between zinc and micronutrients and children’s intelligence and growth. Methods: A total of 430 children were randomly divided into two groups. 210 cases in the observation group were supplemented with zinc and micronutrients; 220 cases in the control group were supplemented with zinc and micronutrients. The differences of cognitive function, IQ, and knee height between the two groups before and after the treatment were compared. Results: The cognitive function and IQ of both groups were significantly higher than those of the control group before and after the test. However, the changes of cognitive function, IQ, and knee height in the observation group were greater than those in the control group There was significant difference between groups (P <0.05). Conclusion: Zinc and micronutrients play a very important role in the intelligence and growth of children. During the growth and development of children, zinc and micronutrients should be properly supplemented to promote their growth.
