ABSTRACT

Objective To understand the levels of calcium ,iron ,zinc and lead elements among children in Weihai area and their change rule in different age periods so as to provide a theoretical guidance for the prevention of related element deficiency and lead poisoning .Methods The levels of lead ,zinc ,calcium and iron were detected in 1 406 children going to our hospital were deected and the results were analyzed .Results The children′s calcium element level in Weihai area showed a declining trend with the age in‐crease ,while the Zn ,Fe and Pb elements levels demonstrated a upward trend .One hundred and three cases of hypocalcemia were de‐tected ,318 cases of low blood iron ,283 cases of low blood zinc and 11 cases of high blood lead were detected in this time .The blood calcium and lead levels had no statistically significance difference among different age groups (P>0 .05);the serum iron and serum zinc levels had statistical different between the 0-1 year old group and other age groups(P<0 .05) .Conclusion The distribution trend of trace elements levels among children in Weihai area is accord with general rule .The incidence rates of low blood zinc and low blood iron are higher .The children′s trace elements levels should be regularly detected .
