摘要

Abstract

This study systematically evaluated five trace elements (Ca

Se) in the whole blood of 4

371 children aged 0–9 in Longgang City. Using ICP-MS and SPSS software

it compared levels across gender and age. Findings show prevalent but uneven micronutrient deficiencies. Calcium (49.61%) and iron (38.73%) deficiencies were most severe

with Ca deficiency increasing significantly with age

especially after four years old. Magnesium deficiency was low (0.52%)

while Mn and Se were sufficient. Boys had lower Ca and Mn levels than girls. Positive correlations between Ca-Mg and Mg-Fe suggest synergistic metabolic effects. In summary

calcium and iron deficiency

particularly after age three

are the primary nutritional concerns. These results provide crucial evidence for targeted dietary guidance

health education

and early intervention

with significant public health implications for disease prevention and child development.
