目的了解长春市0～6岁儿童营养状况与全血内矿物质缺乏情况的关系。方法采取分层整群抽样的方法确定样本量,测量儿童身高、体重,原子吸收光谱法测末梢全血中的矿物质含量。卡方检验分析方法。结果长春市0～6岁儿童体重低下率为2.1%,发育迟缓率为5.86%,肥胖率为9.32%。低铜率2.01%,低锌率52.77%,低镁率0.42%,低铁率35.78%,低钙率15.50%。发育迟缓、肥胖的儿童低铜、低锌、低镁、低铁、低钙率与身高正常、体重正常的儿童比较差异无统计学意义;体重低下的儿童低铜、低锌、低镁、低铁率与体重正常的儿童比较差异无统计学意义。但体重低下的儿童低钙率与体重正常的儿童比较差异有统计学意义,体重低下的儿童低钙率高于体重正常的儿童。结论除体重低下的儿童其低钙率显著高于体重正常儿童外,0～6岁儿童的营养状况对其全血内的钙、铁、锌、镁、铜含量影响不大。
Objective To understand the relationship between the nutritional status of children aged 0 ~ 6 and the deficiency of minerals in whole blood in Changchun city. Methods Stratified cluster sampling was used to determine the sample size, and the height and weight of children were measured. The mineral content in peripheral blood was measured by atomic absorption spectrometry. Chi-square test analysis method. Results The prevalence of underweight among children aged 0-6 years in Changchun was 2.1%, the rate of developmental delay was 5.86%, and the rate of obesity was 9.32%. Low copper rate 2.01%, low zinc rate 52.77%, low magnesium rate 0.42%, low iron rate 35.78%, low calcium rate 15.50%. Children with stunting and obesity had no significant differences in low copper, low zinc, low magnesium, low iron and low calcium among children with normal body weight and normal weight; children with low body weight had lower copper, lower zinc, lower magnesium and lower There was no significant difference in iron rate and normal weight children. However, the children with low body weight had a statistically significant difference in the rate of low calcium among children with normal body weight and the children with low body weight. Conclusion The nutritional status of children aged 0-6 has little effect on the content of calcium, iron, zinc, magnesium and copper in the whole blood of children with low body weight except that of children with normal body weight.
