维生素D对婴幼儿微量元素钙影响的调查

Effect of vitamin D on the content of trace element calcium in infants

目的探讨维生素D对半岁婴幼儿微量元素钙的影响,为婴幼儿正确补钙提供科学依据。方法选取辖区内正常出生的6月龄母乳喂养的婴幼儿186例进行调查,根据钙剂补充情况分为A组62例、B组54例与C组70例;A组仅补充维生素D,B组补充钙剂,C组联合补充维生素D和钙剂,后对186例婴幼儿全血中微量元素钙进行测定,对佝偻病发病情况进行统计。结果 A组婴幼儿缺钙3例(4.8%),C组婴幼儿缺钙2例(2.8%),明显低于B组的9例(16.7%),3组比较差异均有统计学意义(P<0.05);佝偻病发病率A组与C组均为0,B组发病率为3.7%。3组比较差异有统计学意义(P<0.05)。结论正常出生的足月婴幼儿在6个月内补充维生素D即可有效预防钙缺乏和佝偻病。

Objective To explore the effects of vitamin D on the content of trace element calcium in infants to pro-vide scientific basis for correct filling calcium in infants. Methods 186 cases of babies in 0-6 months with breastfeeding in our district were randomly divided into the experiment group（62 cases）,control group（54 cases）and observation group（70 cases）. The experiment group was given vitamin D only,the control group was given calcium,and the observation group was combined with vitamin D and calcium. The trace elements of calcium in blood of 186 cases of babies were measured. The inci-dence of rickets was performed the statistical analysis. Results 3 cases of the experiment group were calcium deficiency （4. 8%）,2 cases of the observation group were calcium deficiency（2. 8%）,which were significantly lower than 9 cases （16. 7%）of the control group,there was significant difference between three groups（P＆lt;0. 05）. The incidence of rickets in experiment group and observation group was 0,which was 3. 7% in the control group,there was significant difference between three groups（P＆lt;0. 05）. Conclusion The application of vitamin D have significant effect of preventing infant calcium defi-ciency and rickets within 6 months in full-term infants with normal birth.
