补锌等微量营养素对儿童体格发育的影响

目的：探讨不同补锌方法对学龄前儿童体格发育的影响。方法：480名6～7岁儿童（城乡各半，男女各半）分为三组：单纯朴锌组（Zn组），不含锌的微量营养素组（M组）和锌加微量营养素组（Zn＋M组）。受试儿童均摄入正常膳食，实验期间（10周）每人每天补充药丸一粒。实验于1994年春、1994年秋、1995年春和1995年秋分四次进行。结果：发现补充多种微量营养素对促进儿童身高体重的增长的效果明显优于单纯补锌（P＜0．05）。结论:说明复合微量营养素的补充能明显促进儿童的生长发育，在补锌的同时必须注意其它营养素的均衡补充。

EFFECT OF THE SUPPLEMENTATION OF ZINC AND/OR MICRONUTRIENTS ON CHILDREN'S PHYSICAL DEVELOPMENT.

Objective: In order to investigate the effect of zinc and/or micronutrients compound intervention on the physicaldevelopment in pre-school children. Methods: 480 children were divided into 3 groups: zinc group, micronutrients group, zincplus micronutrients group. During the experiment of 10 weeks, the children were supplied with zinc, micronutrients or zinc plusmicronutrients respectively. Results: The data showed that the increases of children's height and weight were significantly higherin micronutrients and zinc plus micronutrients groups than those in zinc group. Conclusion: it suggests that the supplementationof mieronutrients compound should promote children's growth and development, and that attention should be paid to the supplementation of other nutrients while zinc be supplied for children.
