摘要
目的：调查本地区学龄前儿童锌（Zn）、铁（Fe）、钙（Ca）、铅（Pb）元素的基本状况,为本地区指导学龄前儿童营养饮食提供依据。方法：采取随机抽样方法,随机抽取本地区2010-2012年3-6岁在读幼儿园儿童4 182例,其中男性2 292例,女性1 890例。使用原子吸收分光光度计测定锌、铁、钙、铅元素含量。结果：2010-2012年男、女童锌、铁元素含量逐年升高,钙元素呈下降趋势、铅中毒率也逐年降低;男、女童之间锌元素含量差异有统计学意义（P〈0.01）,2010年男、女童之间铅中毒率差异有统计学意义（P〈0.01）。男童铁、钙元素含量在2011-2012年差异有统计学意义（P〈0.01）,锌元素含量在2010-2011年差异有统计学意义（P〈0.01）;女童锌、钙元素含量在2010-2012年差异有统计学意义,铅中毒率在2010-2011年差异有统计学意义（P〈0.01）。结论：应注意不同时期学龄前儿童的营养指标,做到早发现、早治疗。
Objective： To investigate the status of zinc,iron,calcium and plumbum in preschool children of the region,provide a basis for guiding nutritional diet among preschool children in the region. Methods： Random sampling method was used to select 4 182 kindergarten children aged 3- 6 years old from the region from 2010 to 2012,2 292 boys and 1 890 girls were included,atomic absorption spectrophotometer was used to detect zinc,iron,calcium and plumbum contents. Results： From 2010 to 2012,the contents of zinc and iron in boys and girls increased year by year,while the contents of calcium showed decreasing trend,and the incidence rate of lead poisoning decreased year by year; there was statistically significant difference in zinc content between boys and girls（ P〈0. 01）,there was statistically significant difference in the incidence rate of lead poisoning between boys and girls in 2010（ P〈0. 01）; there were statistically significant differences in iron and calcium contents of boys between 2011 and 2012（ P〈0. 01）,there was statistically significant difference in zinc content between 2010 and 2011（ P〈0. 01）; there were statistically significant differences in zinc and calcium contents of girls between 2010and 2011,there was statistically significant difference in the incidence rate of lead poisoning between 2010 and 2011（ P〈0. 01）. Conclusion： More attention should be paid to nutritional indexes of preschool children during different periods,then early detection and early treatment may be achieved.
