摘　　要：目的 了解南京市浦口区婴幼儿体内6种微量元素水平及缺乏情况.方法 采集健康体检的6月龄～3岁的婴幼儿无名指末梢血40 μL,采用AA-7000型原子吸收光谱仪测试血中锌、铁、镁、铜、钙、硒6种微量元素含量.结果 调查2 156名婴幼儿中,微量元素平均水平：锌含量为（8.38±2.54） μg/mL,铁含量为（384.29±121.33） μg/mL,镁含量为（90.90±29.76）μg/mL,铜含量为（2.18±0.72） μg/mL,钙含量为（90.00±31.96）μg/mL,硒含量为（0.182±0.019）μg/mL.婴幼儿微量元素缺乏率由高到低依次为铁（31.08％）、锌（25.42％）、硒（15.03％）、钙（14.84％）、镁（1.11％）、铜（0.42％）.婴儿组铁、硒、镁缺乏率低于幼儿组,而锌、钙缺乏率高于幼儿组（P＜0.05）;女童铁、锌、硒、钙缺乏率均高于男童（P＜0.05）.结论 南京市浦口区婴幼儿微量元素缺乏中铁和钙缺乏较为常见,日常膳食中应注意合理补充微量元素从而保障婴幼儿健康成长.Objective To study concentration and deficiency of 6 mieronutrients in 2 156 infants in Pukou district. Methods 40μL of peripheral blood of infants （6 monthss- 3 years old） for health check were collected, concentrations of 6 micronutri- ents （Zinc, iron, magnesium, copper, calcium, selenium） were determined by AA-7000 atomic absorption spectrometer. Results The average concentrations of 6 micronutrients in 2 156 infants： Zinc（8. 38±2.54）/μg/mL iron（384.29± 121. 33） μg/mL magnesium（90.90±29.76）μg/mL, copper（2.18±0.72）μg/mL calcium（90.00±31.96）μg/mL selenium（0. 182± 0. 019）μg/mL. Micronutrient deficiency rates in descending order were iron（31.08%）,Zinc（25.42%）, selenium（15.03%）, calcium（14. 84%）, magnesium（1.11%）, copper（0. 42%）. Deficiency rates of iron, selenium, magnesium in baby group were lower than infant group, while deficiency rates of zinc, calcium in baby group were higher than infant group（P〈0.05） ; girls had higher deficiency rates of iron, zinc, selenium, calcium than boys （P±0.05） . Conclusion Iron and zinc deficiency are common in infants of Pukou District . Dietary should be reasonably supplemented to ensure the healthy growth of infants.
