摘要
本文测查了456名3～6岁儿童的血清钙及身高、体重,就学龄前儿童的钙营养状况及对体格发育的影响进行了探讨。结果表明,低钙总检出率39.25％,以3～岁组最高,5～岁组较低;女童低钙检出率高于男童,统计学分析表明,其差异均有显著性。低钙组儿童身高低于同龄阶段正常者,经统计学处理,4～岁和5～岁组其差异有显著性。3～岁和6～岁组无显著性差异可能与例数少有关。可见,学龄前期儿童中钙营养状况不良情况仍普遍存在,且影响小儿的身高增长.
The height and weight of 456 children aged from 3 to 6 years are measured and serum calsium in the subjects is tested. Based on the information,the influence of the calsium nutrition state on the physical development in preschool children is investigated. The results show that the total morbidity of calsium deficiency in children is 39. 25% , and it reaches its highst level in the group aged 3 years, but it is lower in the group aged 5 years. Furthermore morbidity of calsium deficiency in female group is higher than that in male group. According to statistical analysis,the differences above mentioned appear obviously. The height of children suffering from calsium deficiency is lower than that of healthy children in same age. From statistical analysis it follows that differences between groups aged 4 years and aged 5 years are evident,but they are not so between groups aged 3 years and aged 6 years. It iis probably attributed to the shortage of samples. Finally it is concluded that the calsium defficiency appears in preschool children frequently, and it influences growth of height in children.
