Objective To better understand the micronutrient status of preschool children.Methods A total of 845 preschool children were randomly selected and blood samples were collected to measure serum micronutrient level such as zinc,iron,calcium,vitamin A and others.SPSS 17.0 software was used to analyze the data.Results The medians of vitamin A,copper,zinc,calcium,magnesium and iron were 1.90±1.05 μmol/L,23.3±3.64 mmol/L,84.3±39.4 μmol/L,1.66±0.33 mmol/L,1.59±0.46 mmol/L and 8.90±2.48 mmol/L respectively.There were only 65.92% of children whose vitamin A level was in the normal range,while more than 90% were in reference interval in terms of serum levels of copper,zinc,calcium,magnesium,and iron.There were significant differences for vitamin A among different age-groups and children from rural and urban areas(P0.05).Conclusions There are 35% of preschool children surveyed are vitamin A deficient,coupled with a certain number of other micronutrient deficiencies indicating that early micronutrient supplementary should be given to those preschool children.
