title: [Evaluation on the iron absorption of prepubertal children using stable isotopic tracer].
abstract: OBJECTIVE
  To investigate the iron absorption of prepubertal children using stable isotopic tracer.
  
  
  METHODS
  57 subjects were orally given 57FeSO4, in conventional diet mode, before breakfast and supper and totally for 5 days. All the fecal during the specified time were collected, pre-conducted and determined by AAS and MC-ICP-MS to evaluation the iron absorption of prepubertal children.
  
  
  RESULTS
  The iron absorption rate of male and female were (26.71 +/- 2.94)% and (29.76 +/- 2.20)%, and the correction absorption rate of iron were (27.45 +/- 2.83)% and (31.01 +/- 2.48)%, absorption of female were higher than that of male (P < 0.05).
  
  
  CONCLUSIONS
  In the condition of fasting oral SI, there is a high iron absorption rate of prepubertal children, and absorption rate of female is higher.
