摘要
本文通过抽样调查发现,病区儿童少年手掌骨皮质厚度显著落后于非病压,随看年龄的增大,骨皮质落后的差距越大。病区骨龄落后1岁以上者达38.5%,并且骨龄落后以11～13岁组所占比例最大为50.0％,病区骨龄平均落后0.632岁,病医种耔骨的出现年龄显著落后于非病要。提示缺碘严重影响女性月经初潮,推迟生理性突增,延缓生长发育。
Through sample investigation this article disco ers that the cortex thickness of palm bone of children and tee.igers in endemic disease area is much poorer than the normals.

In the disease area backwards bone age over one year old account for 38.5 per cent.and the group of eleven to thirteea years old which possess the biggest proportion amount to 50.0 Per cent. The bone age in disease area is average backwards 0.632 year old .The appexrance age of sesamoid bone in disease area is lemarkalle backwards to normal area.This suggest that deficiency in Iodine influences seve rely the female menarche, postpones Physiologic character sudden addition and puts up growing development.
