摘　　要：目的　探讨学龄前儿童血锌、铁、钙值与健康状况的关系 ,及对低锌儿干预治疗后的情况分析。方法　采用群体自愿参加者取静脉血 ,检测血清锌、铁、钙。检测前向家长发问卷调查饮食习惯、易感染情况。抽血后测身高、体重。对检出低锌儿分药物组、食疗组 ,治疗三个月后 ,再复查血锌、钙。结果　 112 5例受检学龄前儿童中存在一项异常者 6 19例 (5 5 % ) ,同时存在两项异常者 195例 (17.3% ) ,同时存在三项异常者 17例 (1.5 % )。血锌值低于正常者 5 15例 (4 5 .7% ) ,有不良饮食习惯儿 342例 (30 .4 % ) ,有轻度营养不良 189例(16 .8% ) ,身高不达标 342例 (30 .4 % ) ,复感儿 5 0 8例 (4 5 .2 % )。药疗组和食疗组治疗后血锌水平升高 ,与治疗前相比 ,P <0 .0 1,差异有显著意义。结论　本组儿童低血锌情况显著 ;血锌值与饮食习惯、易感染情况、身高有密切关系 ;儿童低血钙者较少 ,低血钙与不良饮食习惯有关 ;药疗及食疗均能纠正低血锌值 。Objective To investigate the relationship between the serum zinc, iron and calcium value in preschool children and their health conditions as well as,analysis their change among the children with hypocalcium and hypozinc after having given intervention.Methods To take the intravenous blood sample of voluntary participants and test serum zinc and calcium values with the questionnaires from parents for the information regarding children's diet habit and susceptibility to infection.The height and weight were also recorded. The children with lower levels of serum zinc and calcium were divided into two groups: diet therapy group and drug therapy group. Three months later after treatment, the serum values of calcium and zinc were retested.Results 619 cases (55%) out of 1125 children had one abnormal paremeters at least , and 195(17.3%)cases had both hypocalcium and hypozinc. 17 cases(1.5%) had lower levels of the serum zinc, iron and calcium value. There were 515 children (45.7%) in lower level of serum zinc. 342 cases out of all the tested children had bad diet habit (30.4%). 189 cases (16.8%) suffered from slight malnutrition are and the children of lower than normal in height had 342 cases (30.4%) and 508 cases (45,2%) had susceptibility to infection.Serum zinc in drug therapy group and diet therapg group in creased significantly(P<0.01).Conclusion serum zinc level in this tested group is seriously low. The serum value of zinc in preschool children is associated with the diet habit, infectious susceptibility and height of children and hypocalcium is related to bad diet habit. Both drug therapy and diet therapy can correct children's hypozinc and medication is a most effective method for treating the children with hypozinc.
