摘要
目的:研究机体营养状况与微量元素之间的关系,探索微量元素在机体营养状况评定中的作用。 方法:使用病例对照研究。在普外科按入院顺序选择100 例住院病人作为研究对象,42 例被划入营养不良组(研究组),58例为无营养不良组(病例对照组),另取50 例健康查体者作为正常对照组。对所有入选者测定Alb、TFN、CHI、TLC、% UBW 及铁、锌、铜、硒。三组所有资料均由SPSS7.5软件包在计算机上进行分析。 结果:Alb、TFN在研究组与其他两组之间存在显著性差异,CHI在三组之间均存在显著性差异。同时,研究组及病例对照组的血清微量元素明显低于正常对照组,尤其是研究组,且组间具有显著性差异。微量元素与营养指标间具有正相关关系(P<0.05)。判别分析结果表明,硒、锌、铜三项建立判别函数,回代检验结果显示,判别函数具有一定的判别能力,且敏感度较高。 结论:血清微量元素与营养指标间具有正相关。
Objectives:To study the relationship between the nutritional status and the trace elements status of the body,and to research the role of the trace elements in nutritional assessment of the patients. Methods:The case control study was used.100 cases of hospitalized patients in general surgery were examined.At the same time,50 healthy persons were as controls.Alb,TFN,CHI,TLC,%UBW and serum Fe,Zn,Cu,Se were determined.42 cases were divided into malnutrition group (study group),and 58 cases were in non malnutrition group.All data of 3 groups were analysed on PC by SPSS7.5. Results:Alb and TFN had a significant difference in study group with case control group or normal group.The CHI had a significant difference among three groups.Serum trace elements(Fe,Zn,Cu,Se) of study group and case control group were lower than normal group.The correlation study of nutritional parameters and trace element showed that the trace element had a positive correlation with the nutritional parameters. Conclusions:The serum trace elements have a positive correlation with nutritional parameters.The trace element is capable of discrimination for nutrition status of body.
