title: [Pre- and post-iodine nutritional status among the population related to the practice of new standard on edible iodized salt, in Yunnan province].
abstract: OBJECTIVE
  In order to understand the iodine nutritional status, after the salt-iodine content was showed a reduction in 2012 and to evaluate the current situation after the new standards was brought into force to the general population in an experimental community of Yunnan province.
  
  
  METHODS
  Randomly sampled urine and salt were collected, to test the iodine concentration in the study-site. Pre-and post-levels of the iodized salt under the provision of the new standards, were identified.
  
  
  RESULTS
  of this study were gathered upon 3 weeks or 3 months, respectively. Results Data from the three randomly chosen study sites showed that the urine iodine concentration in the general populations was reducing gradually. In the general population, medians of Urine Iodine (MUI) were 279.71 µg/L, 239.64 µg/L and 226.26 µg/L, respectively. Proportion of the urine iodine value for 100-199 µg/L increased but ≥300 µg/L decreased, after the new standard was put into practice. Both homogeneity and stability of the new standard on iodized salt seemed to be good.
  
  
  CONCLUSIONS
  Iodine nutrition in general population appeared reasonable under the use of newly set salt-iodine standards in general population living in Yunnan province.
