| 摘 要： | 目的 探讨学龄前儿童微量元素及营养摄入对身高体重的影响。 方法 选取2013年9月-2014年9月期间入学衢江区300例不同幼儿园的学龄前儿童作为研究对象,并指导学校老师及家长记录每个学生连续3 d的膳食摄入情况,按儿童食欲及主食摄入量分为过量组、良好组、中等组及低下组,各75例。随访儿童12个月间的饮食状况,比较各组间生长发育情况,并分析身高体重与营养物质及微量元素的相关性。 结果 各组完成随访并符合最终入组研究的儿童例数分别为48例、56例、57例及47例。良好组儿童12个月后身高及身高增量均高于其他各组(P<0.05),过量组与中等组儿童身高增量差异无统计学意义(P>0.05),但均高于低下组(P<0.05)。而过量组12个月后体重及体重增量均高于其他各组(P<0.05),良好组及中等组的体重增量均高于低下组(P<0.05)。身高、体重与蛋白质、热能、钙、铁、锌的摄入量呈显著正相关(P<0.05),且钙、铁、锌等摄入量与蛋白质及热量的摄入呈正相关(P<0.05)。 结论 学龄前儿童的微量元素及营养的合理摄入对其自身的生长发育有着积极的作用,营养摄入不足或过剩均对其身高增长有着负面影响,应针对不同儿童的营养缺乏情况制定个体化方案进行干预。

| Abstract: | Objective To investigate the effect of trace elements and nutritional intake on height and weight in preschool children. Methods Total 300 preschool children in different kindergarten from September,2013 to September,2014 were chosen and divided into excess group,good group,middle group and low group according to the diet intake for 3 days,with 75 cases in each group.The dietary status of children was followed up for 12 months.The growth indexes in different groups were compared and the correlation was analyzed. Results The numbers of children in each group were 48 cases,56 cases,57 cases and 47 cases,respectively.The height and the height increment of the good group were higher than those in other groups (P<0.05)12 months later;there was no significant difference in height and height increment between the excess group and the middle group (P>0.05),while either of them was higher than the low group (P<0.05).The weight and the weight increment of the excess group were higher than those in other groups (P<0.05)12 months later;there was no significant difference in weight and weight increment between the good group and the middle group (P>0.05),while either of them was higher than the low group (P<0.05).There were positive correlation between the growth index (height and the weight) and the nutrition (protein,energy,calcium,iron,zinc,all P<0.05),and calcium,iron,zinc and protein and caloric intake was positively correlated (P<0.05). Conclusion The trace elements and nutrition of rational consumption in preschool children has a positive role in growth and development,and deficiency or excess of nutritional intake have a negative impact on its height growth.It's necessary to develop individualized intervention according to the lack of nutrition conditions. |
