作者对102例1～16岁主诉为生长发育迟缓的儿童进行了平均4个月的补锌观察,口服硫酸锌的剂量为每日每公斤体重3～7毫克。服锌前后除准确测量身高和体重以外,还用原子吸收分光光度计测定了头发中锌的含量。身高体重则以九市儿童青少年体格发育调查研究资料和同期观察了1～6岁235名健康儿童的生长发育速度作为比较。结果发现在服锌前后发锌含量分别为81.9±29.6ppm与137.9±47.2ppm,前后差别非常显著。1～6岁男童服锌前后的身高及体重平均月增长值与同龄正常男童的平均月增长值分别为1.09±0.63厘米与0.66±0.63厘米;体重为0.35±0.33公斤与0.27±0.2公斤,差别均非常显著。女童之间相比差别也非常显著。20例儿童以自身为对照在服锌前后的身高平均月增长值相差0.57厘米,有非常显著性差别。本实验结果表明,补锌对北京地区的儿童有促进生长的作用。
The authors conducted an average of 4 months of zinc supplementation in 102 children aged 1 to 16 years with growth retardation. Oral doses of zinc sulfate ranged from 3 to 7 mg / kg body weight per day. Before and after serving zinc in addition to accurately measure the height and weight, but also with the atomic absorption spectrophotometer to determine the hair zinc content. Height and body weight to nine cities of children and adolescents physical development survey data and the same period observed 1 to 6 years old 235 healthy children growth and development as a comparison. The results showed that zinc content before and after serving zinc were 81.9 ± 29.6ppm and 137.9 ± 47.2ppm, before and after the difference is very significant. The average monthly growth of height and weight of boys aged 1 ~ 6 years before and after taking zinc was 1.09 ± 0.63 cm and 0.66 ± 0.63 cm respectively compared with that of normal boys of the same age; the body weights were 0.35 ± 0.33 kg and 0.27 ± 0.2 kg , The difference is very significant. The difference between girls is also significant. 20 cases of children as their own control before and after taking the average height growth of zinc difference of 0.57 cm, there is a very significant difference. The results of this experiment show that zinc supplementation can promote the growth of children in Beijing.
