目的探讨本地区儿童锌、铜、铁、钙、镁水平。方法昆明市城区2～9岁健康儿童532名,其中男234名、女298名。分为幼儿(0～3岁)、学龄前儿童(4～6岁)、学龄儿童(7～14岁)三个组测定锌、铜、铁、钙、镁水平。结果男女儿童之间Zn、Cu有显著性差异(P<0.01);各年龄段之间,Zn、Fe、Ca有显著性差异(P<0.01)。
Objective To explore the zinc, copper, iron, calcium and magnesium levels in children in this area. Methods A total of 532 healthy children aged 2 ~ 9 years old in Kunming city were enrolled, 234 were male and 298 were female. The children were divided into three groups: young children (0-3 years old), preschool children (4-6 years old) and school-age children (7-14 years old). The levels of zinc, copper, iron, calcium and magnesium were determined. Results There was a significant difference in Zn and Cu between boys and girls (P <0.01). There was significant difference in Zn, Fe and Ca among all ages (P <0.01).
