| Objective To investigate the condition of Lanzhou city kindergarten child's dietary pattern and nutrition status in present stage. Study the physical development, Determination of Zinc,Calcium,ferrum in Plasma by Atomic Absorption Spectroscopy, all of these provide basis for improving nutritional condition next stage and put forward rationalization proposals.Methods Five days dietary survey by using weighing methods, And the data was analyzed and evaluated at Chinese dietary guide and Chinese DRIs. Body weight and height were measured by unitize measurement Z score was adopted to evaluate the growth status and nutrition state. Determination of Zinc, Calcium, ferrum Plasma by Atomic Absorption Spectroscopy.Results Dietary pattern of the subjects was mainly consisted of grains and Starches and Tubers. The intakes of milk, beans and nuts, marine products were insufficient. The intakes of Oil and salt were low.The total energy was provided by fat was insufficient and carbohydrate was higher. nutrient intake less than 80.0% of RNI (or AI), including energy(79.86%), protein(78.67%), Vitamin A(78.35%), Vitamin B1(78.57%), VitaminB2(57.14%), Calcium (39.45%), iodine (12.67%) magnesium(75.94%), zinc (60.67%), selenium (73.40%); high quality proteins and heme iron from food were lower. The Proportion of energy provided from Breakfast, Lunch and Supper was inappropriate, the proportion of Breakfast was lower and Lunch was higher.There was statistical significance in physical development between 5-year-old boy and girls among LanZhou city and boys' weight and height measured mean value all higher than girls'.The children of Lanzhou compared with the national survey growth of children's in nine cities of China in 2005,they were in same level for age and sex;Assessment of growth and development as "medium" was most,followed by "high middle",the "finest grade" and the "middle lower", "low grade" at least.There were no underweight children,the prevalence of stunting,wasting, overweight,and obesity were 1.18%,1.18%,12.86%,9.43%,respectively.The prevalence of stunting,wasting, underweight children was lower than BeiJing,TangShan,HeFei and ShenZhen city. The prevalence of overweight and obesity only lower than TangShan city children.Ca:3 years group were higher than 4～6 group, and 4～6 years group there were no difference. Fe,Zn, There were no significant differences among 3～6 group. The three elements of comparison with standard value, the deficient rate of calcium was 10.95%, the deficient rate of iron is 13.32% and zin is 9.63%.The deficient rate of iron and zin comparison with ShanXi, BeiJing,Xiamen and XinXiang were lower than them, The deficient rate of calcium was higher than ShanXi, Xiamen.Conclusion Indicated that kindergarten child meals nutrition distribution and matching in district was unreasonable. The Nutritional Status of the Kindergarten should be improved. So it is necessary to increase the consumption of milk, beans and nuts, marine and adopt three meals and two extra meals in a day. Give the reasonable meal regimen and the nourishment of the well balanced.The malnutrition rate of preschool children in Lanzhou was low and nutrition status was good, but overweight and obesity were higher.In the future the overnutrition should be more concerned about in this region, and promote children's development nutritional health and reduce the overnutrition rate at the same time.Children refers to three Mineral elements level blood is consistent with dietary survey, but except consider dietary factors; reexamine Mineral elements and combining clinical diagnosis and other laboratory examinations.
