摘　　要：[目的]观察补充复合微量营养素对城镇儿童体质健康状况的改善效果。[方法]采用实验流行病学,将163名8～11岁城镇儿童随机分成2组,分别补充复合微量营养素和安慰剂。试验采用随机双盲设计,时间为4个月。在干预前、后分别对两组儿童进行生长发育(身高、体重等)、机能(安静脉搏、肺活量)、体能(立定跳远,仰卧起坐等)3类体质指标测量和血红蛋白、维生素B2 4 h尿负荷试验测定。[结果]试验组男童体质综合评价分值(P=0.041)、体重增加值(P=0.005)、安静脉搏的降低值(P=0.011)、立定跳远提高成绩(P=0.000)、女生仰卧起坐提高成绩(P=0.018)均显著高于相应对照组;两组之间血红蛋白,4 h负荷尿维生素B2排出量在干预前后差异均无统计学意义,但试验组儿童贫血率有所降低,4 h尿负荷试验维生素B2排出量有所增加。[结论]补充复合微量营养素在一定程度上可改善儿童体质状况。[Objective]To study the effect of multi-micronutrients on constitution of children in town.[Methods]Experimental epidemiology was used in this study.163 pupils aged 8 to 11 in town were divided into 2 groups.The subjects in one group were given multi-micronutrients,and the others were given placebo as the control.The trial was designed as randomized double blind control trial and it lasted for four months.Some indexs such as shape（e.g.height,body weight）,function（e.g.quite pulse,vital capacity）,physical fitness（e.g.long-jump,sit-up in one minute）,hemoglobin and Vitamin B2 evaluded by four-hour loading trial were measured before and after the intervention.[Results]The results of test group were statistically better than the control in the increase of body weight,long-jump,sit-up and in the decrease of quite pulse.There was no statistical difference in hemoglobin,Vitamin B2 evaluded by four-hour loading test,but the good trend was indicated.[Conclusion]The results indicate that the multi-micronutrients can impove the constitution of children.
