title: [A cross-sectional study on iodine nutrition in general population from Zhejiang province, China].
abstract: OBJECTIVE
  To understand the current status of iodine nutrition among the community residents to compare the level of iodine nutrition in different areas and groups of populations in Zhejiang province.
  
  
  METHODS
  Stratified cluster sampling method was adopted and residents from twenty-two communities in Zhejiang province were selected. A cross-sectional survey was conducted, using questionnaires, laboratory tests, on urinary iodine, water iodine and the concentration of the iodine in salt, which had played positive roles in the calculation of the level of iodine nutrition.
  
  
  RESULTS
  of the iodine nutrition in this cross-sectional survey were as follows: the median water iodine and salt iodine of Zhejiang were 2.42 µg/L and 28.8 mg/kg, respectively. The coverage of iodized salts was 79.54%, with the ingesting rate of qualified iodized-salt as 76.65% and the median content of urinary iodine in the population of Zhejiang was 161 µg/L. The average iodine content among pregnant women was 138 µg/L, with the percentage of samples less than 100 µg/L as 25.92%, more than 300 µg/L as 15.30%. The proportions of iodine intake through water, salt and other foods were 1.70%, 76.41% and 21.89%, respectively.
  
  
  CONCLUSIONS
  The status of iodine nutrition in Zhejiang province in general seemed to be appropriate, but the level of iodine nutrition in pregnant women was less than the requirement, which should call for attention.
