摘要
Few researches have been conducted on elements in whole blood of young people. Our study was to investigate the influence of age, gender and season on the contents of magnesium (Mg), calcium (Ca), iron (Fe), copper (Cu), zinc (Zn), manganese (Mn), selenium (Se), and strontium (Sr) as well as to establish reference intervals (RIs). We conducted a retrospective study of 589 apparently healthy children and adolescents. Quantitative analysis had been carried out using inductively coupled plasma-mass spectrometry (ICP-MS). Test results were analyzed using and MannWhitney U test, Spearman and Pearson statistical analyses. RIs were defined by using 95% confidence interval. Differences between contents of Mg, Fe, Cu, and Zn in girls' and boys' whole blood were found. Positive correlations for Fe, Zn, Se, and Sr, while negative for Ca and Cu were found with age. Increasing trends were found for Fe, Zn, and Se, while for Ca and Cu, changes were even decreasing for children and teenagers. The most frequently correlating element pairs were FeZn, MgSe, and FeSe in five successive age groups. Lower contents of Mg, Ca, Fe, Zn, and Se were found in summer. Finally, the reference interval of each element was initially established according to age and gender grouping. The contents of elements in whole blood vary depending mainly on the gender and age of children and adolescents. The reference intervals of elements in whole blood grouped by age and gender provide a reference basis for clinical diagnosis and treatment of element-related diseases.
