1、钙、锌、维生素A对儿童生长发育的作用探析,儿科论文摘 要: 目的 研究儿童补充钙Ca、锌Zn、维生素A(VA促进其生长发育的效果。方式方法 选择2021年8月至2021年1月我院就诊的100例35岁儿童作为研究对象,根据年龄与性别大致相匹配原则分为Zn+Ca+VA组、Zn+Ca组、Zn组和对照组,每组25例。Zn+Ca+VA组口服VA 200 g/d,Ca 250 mg/d,Zn 3.5 mg/d;Zn+Ca组口服Ca 250 mg/d,Zn 3.5 mg/d;Zn组口服Zn 3.5 mg/d;对照组给予相应的安心抚慰剂;均持续服用12个月。比拟各组儿童父母的年龄、身高及儿童的出生体重,每隔4
2、个月对各组儿童进行一次膳食调查和体格检查身高、体重,并分别于研究前、后测量一次骨龄,计算骨龄增长值。结果各组的父母年龄、身高、儿童年龄、儿童出生体重比拟,差异无统计学意义P 0.05。各组儿童在第4、8、12个月末的蛋白质摄入和总能量摄入比拟,差异无统计学意义P 0.05。第12个月末时,Zn组儿童身高显着高于对照组P 0.05;第8、12个月末时,Zn+Ca组、Zn+Ca+VA组儿童身高均显着高于对照组P 0.05。第12个月末时,Zn+Ca组儿童体重显着大于对照组P 0.05;第8、12个月末时,Zn+Ca+VA组儿童体重显着大于对照组P 0.05),Zn+Ca+VA组儿童体重显着大于Zn
3、+Ca组P 0.05。Zn组增加的身高显着多于对照组P 0.05);Zn+Ca组和Zn+Ca+VA组增长的体重、增加的身高均多于对照组P 0.05;各组儿童的骨龄增长值比拟,差异不具有统计学意义P 0.05。结论 补充Ca、Zn、VA能够更好的促进儿童的生长发育。 本文关键词语: 钙; 锌; 维生素A; 微量元素; 生长发育; Abstract: Objective To study the effect of calcium(Ca), zinc(Zn) and vitamin A(VA) supplementation on children s growth and development
4、. Methods From August 2021 to January 2021, 100 children aged 3-5 years old admitted in our hospital were selected as the study objects. According to the principle of roughly matching age and gender, the children were divided into Zn+Ca+VA group, Zn+Ca group, Zn group and control group, with 25 case
5、s in each group. The 200 g/d of VA,250 mg/d of Ca and 3.5 mg/d of Zn were taken orally in the Zn+Ca+VA group; 250 mg/d of Ca and 3.5 mg/d of Zn were taken orally in the Zn+Ca group; 3.5 mg/d of Zn was taken orally in the Zn group; corresponding placebo was given in the control group; the children al
6、l continued to take those for 12 months. The parents age, height and birth weight of children in each group were compared. Every four months, the children in each group were given a dietary survey and physical examination(height and weight). The bone age was measured before and after the study, and
7、the growth value of bone age was calculated.Results There were no significant differences in parents age, height, children s age and birth weight in each group(P 0.05).There were no significant differences in protein intake and total energy intake of children in each group at the end of the 4 th,8 t
8、h and 12 th month(P 0.05). At the end of the 12 th month, the height of children in the Zn group was significantly higher than that in the control group(P 0.05); at the end of the 8 th and 12 th month, the height of children in the Zn+Ca group and the Zn+Ca+VA group were significantly greater than t
9、hat in the control group(P 0.05). At the end of the 12 th month, the weight of children in the Zn+Ca group was significantly greater than that in the control group(P 0.05); at the end of the8 th and 12 th month, the weight of children in the Zn+Ca+VA group was significantly greater than that in the
10、control group(P 0.05), and the weight of children in the Zn +Ca +VA group was significantly greater than that in the Zn+Ca group(P 0.05). The increased height in the Zn group was significantly more than that in the control group(P 0.05); the increased weight and height in the Zn+Ca group and in the
11、Zn+Ca+VA group were more than those in the control group(P 0.05); there were no significant differences in bone age growth among children in each group(P 0.05). Conclusion Ca, Zn and VA supplementation can better promote the growth and development of children. Keyword: calcium; zinc; vitamin A; trac
12、e elements; growth and development; 据相关调查结果得知,我们国家儿童生长发育延迟缓慢现象比拟普遍1。儿童生长发育延迟缓慢与儿童从膳食中摄入的维生素缺乏有关2,而钙Ca、锌Zn、维生素A(VA的摄入在儿童生长发育经过中尤为重要,因而给予儿童及时的补充有重要意义。临床上对儿童生长发育延迟缓慢的治疗方式方法以及时补充各种微量元素为主,本文选取我院收治的100例35岁儿童作为研究对象进行分析,详细内容如下。 1 、资料与方式方法 1.1 、一般资料 选择2021年8月至2021年1月于我院就诊的100例儿童为研究对象,年龄35岁,平均4.62 0.54岁;男58例,
