title: [Investigation on the iodine nutritional status and the prevalence of thyroid carcinoma in Zhoushan Archipelago residents].
abstract: OBJECTIVE
  To investigate the nutritional status of iodine and the prevalence of thyroid carcinoma of residents in Zhoushan Archipelago, and to explore the related factors influencing the prevalence of thyroid carcinoma.
  
  
  METHODS
  The residents in Zhoushan Archipelago were selected by cluster random sampling. The subjects were surveyed by questionnaire, their thyroids were examined by B-ultrasonography, the thyroid function and the levels of urine iodine were analyzed. Pathological diagnosis was conducted to the patients suspected of thyroid carcinoma.
  
  
  RESULTS
  The median levels of urine iodine in urban residents, famers, salt-makers, fishermen from Zhoushan and buddhists from Putuoshan were 320.7, 188.9, 122.2, 193.6 and 271.7 microg/L respectively, while the prevalence rates of thyroid carcinoma were 215/100 000, 398/100 000 0, 407/100 000, 829/100 000,340/100 000, respectively; The age or a higher level of hTSH of a person were risk factors for suffering from thyroid carcinoma.
  
  
  CONCLUSIONS
  The iodine intake of residents in ZhouShan Archipelago is adequate and the prevalence rate of thyroid carcinoma is high. Serum hTSH could be used as a predictor for the risk of thyroid carcinoma.
