十堰地区学龄前儿童单纯性肥胖与体内微量元素水平关系探讨

目的检测单纯性肥胖儿童体内7种微量元素的含量，并探讨其与单纯性肥胖的关联。方法在十堰地区选择85例单纯性肥胖学龄前儿童作为观察组，另选85例正常体重学龄前儿童作为对照组，测定并比较两组儿童全血铁、钙、锌、镁、铜、铅、硒含量。结果观察组在全血Fe、Zn、Cu、Ph、Se含量及Cu／Zn比值方面与对照组存在统计学差异（P〈0．05），Zn、Se相对缺乏、Ph量过高及Cu／Zn比值降低是学龄前儿童单纯性肥胖相关因素。结论单纯性肥胖学龄前儿童体内普遍存在微量元素紊乱，微量元素稳态失调在其脂代谢紊乱发生中可能起着一定作用。

Analysis of Trace Elements in Blood of Preschool Children with Simple Obesity in Shiyan City

Objective To explore the differences of seven kinds of trace elements between obese and normal-weight preschool chil- dren,and investigate its relationship. Methods All of 85 cases of obese of Shiyan city were selected as observation group, another 85 normal children as control group,determined and compared the contents of iron , calcium , zinc , magnesium , copper, lead and selenium be- tween two groups. Results There was significant difference in the contents of Fe,Zn,Cu,Pb,Se and Cn/Zn ratio （P〈0.05）,relative lack of Fe and Se,relative excess of Pb,and lower Cu/Zn ratio were the risk factors of child obesity. Conclusion There is an overall change of trace elements among obese children.
