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.
This article examined 456 children aged 3 to 6 years of serum calcium and height, weight, calcium nutrition in preschool children and the impact on physical development were discussed. The results showed that the total detection rate of low calcium was 39.25%, which was the highest in 3 ~ group and lower in 5 ~ group. The detection rate of low calcium in girls was higher than that in boys. Statistical analysis showed that the difference was significant. Children in the low-calcium group had a lower height than those of the same age group. After statistical analysis, the difference was significant between the 4-year-old group and the 5-year-old group. There was no significant difference between 3 ~ 6 years old and 6 ~ Visible, preschool children in poor nutrition status of calcium is still widespread, and affect the growth of children’s height.
