本文对湛江市两所幼儿园239名儿童生长发育水平状况进行调查，同时对其发锌、钦、铜含量也进行了测定，并对它们之间的相互关系进行了初步探讨。结果表明：湛江市学龄前儿童生长发育水平处于中等等级的占大多数，为71．55％，而处于中上等等级的比例最低，仅占10．04％，应引起社会的足够重视。另外生长发育处于中上等级与中下等级的发锌、铁的含量有差异（P＜0．05），前者高于后者。因此，对生长发育处于较低水平的儿童应适当补充锌和铁，以促进其生长发育．调查结果还显示在学龄前儿童各年龄组之间发锌、铁、铜的含量无差别。
This paper investigated the growth and development status of 239 children in two kindergartens of Zhanjiang City. At the same time, the contents of Zn, Cu and Zn in the two kindergartens were also determined, and the relationship between them was also discussed. The results showed that the growth and development level of preschool children in Zhanjiang was 71.55%, while the lowest in middle and upper grades, accounting for only 10.04%, which should be paid enough attention by the society. In addition, growth and development in the upper and lower levels of hair zinc, iron content were different (P <0.05), the former is higher than the latter. Therefore, children with low growth and development should be properly supplemented with zinc and iron to promote their growth and development. The survey also showed no difference in zinc, iron, and copper levels among preschool children of all ages.
