Abstract
BACKGROUND: Microelement. An important index of the microelement content in hunan body, manifests various kinds of information on health and nutrition status. Therefore, research on the rules and correlations of microelenent content in children's hair as age changes, and on how to regulate clfild nutrition reasonably has quite a significant meaning.OBJECTIVE: To discover the rules of zinc and calcium content in children's hair as age changes through masses of random surveys and statistics for the content of microelement in children's hair samples. To provide theoretical evidence for the research on how to formulate the standard of microelement content in children's hair and regulate child nutrition reasonably.It is of great significance.DESIGN: Random sampling study.SETTING, PARTICIPANTS and INTERVENTIONS: Children below six years old in Wenan County of Langfang City, whose hair was selected as the sample. The sample was desiccated after washing, weighed accurately,then drying cineration was performed, after that, it was extracted by hydrochloric acid in one to one made up to, fixed volume with 1% SrCl2,measured by flame atom absorbing method with the instruments' most optimized situation. Estimation results of more than 1 000 hair samples were statistically analyzed, with the children aged from several days to six years old. The average value of different age stages were collected.MAIN OUTCOME MEASURES: Comparison of corresponding zinc and calcium content at different ages.RESULTS: Content of zinc and calcium in the newborn infants' hair (four months old) is higher. Six months later, the content reduced gradually and remained low at the age of 1.5 to 2.5 years, it increased after 3 years old.For instance: the average content of zinc and calcium in two-month-old children's hair is 190 and 1 432 tμg/g; 18-month-old children is 115 and 412 μg/g; seventy-month-old (6 years old) children is 147 and 606 μg/g respectively.CONCLUSION: Zinc and calcium content in preschool children's hair as age changes shows evident regularities.关键词
