目的研究血液微量元素水平与儿童生长发育状况的相关性,为日常生活、临床工作明确儿童血液微量元素的重要性及促进儿童健康管理寻找理论依据。方法选取2015年12月—2016年12月在金华市妇幼保健院内分泌科就诊的儿童720例,利用标准差离差法对生长发育状况及微量元素水平标化;不同性别及不同生长发育疾病下微量元素水平的差异比较采用t检验;不同年龄组间微量元素的差异比较采用单因素方差分析。P<0.05为差异有统计学意义。结果男女铅、钙元素对比差异有统计学意义(P<0.05),各年龄组间微量元素对比差异有统计学意义(P<0.05);矮小儿童铅水平高于健康者,镁却低于后者;营养不良者锌低于健康者,钙低于后者;性早熟者铅高于健康者,铁高于后者,对比差异均有统计学意义(P<0.05)。结论血液微量元素水平与儿童健康状况密切相关,需重视不同阶段、不同疾病儿童的膳食结构,重点关注锌、铁,更好地促进儿童健康成长。
Objective To study the relationship between blood trace elements and children’s growth and development, and to find out the theoretical basis for daily life and clinical work to clarify the importance of children’s blood trace elements and to promote children’s health management. Methods A total of 720 children were enrolled in the Department of Endocrinology, Maternal and Child Health Hospital of Jinhua City from December 2015 to December 2016. The standard deviation method was used to standardize the growth and development status and trace element levels. Different gender and different growth and development diseases The levels of trace elements were compared by t-test. The differences of trace elements in different age groups were compared by one-way ANOVA. P <0.05 for the difference was statistically significant. Results There was significant difference in lead and calcium between men and women (P <0.05), and the difference of trace elements in all age groups was statistically significant (P <0.05). The lead levels in dwarf children were higher than those in healthy children ; Malnutrition, zinc is lower than healthy people, calcium is lower than that of the latter; lead of the precocious puberty is higher than that of the healthy, iron is higher than the latter, the difference is statistically significant (P <0.05). Conclusion The levels of trace elements in blood are closely related to children ’s health status. The dietary structure of children with different stages and diseases needs to be emphasized. Zinc and iron should be the focus of attention and the healthy growth of children should be promoted.
