为了解与改进学龄前儿童的营养状况,对南京市五所幼儿园1000名2～5岁的儿童进行营养调查。结果表明,各年龄组儿童热能、蛋白质和大部分营养素的摄入量均接近或超过了全天RDA的50％,但也存在某些营养素摄入量明显不足。如钙的摄入量四个年龄组分别为RDA的15.8％、11.7％、12.2％和13.1％;锌的摄入量为RDA的35.1％、36.4％、37.5％和38.0％;VC、VB_1和VB_2的摄入量略显不足。儿童中Caup指数在10～13的占2.0％,在13～15的占29.3％,血红蛋白在110g/L以下者占34.6％。
In order to understand and improve the nutritional status of preschool children, 1000 children from 2 to 5 years old in five nurseries in Nanjing were investigated. The results showed that children’s caloric intake, protein and most nutrients in children of all ages were close to or surpassed 50% of RDA throughout the day, but there were also significant deficits in some nutrients. Calcium intake was 15.8%, 11.7%, 12.2% and 13.1% of the RDA for the four age groups and 35.1%, 36.4%, 37.5% and 38.0% for the RDA for zinc; VB_2 intake slightly less than adequate. In children, the Caup index was 2.0% at 10-13, 29.3% at 13-15, and 34.6% at hemoglobin below 110g / L.
