title: [Exploratory study on the association between different iodine nutrition and the prevalence of dyslipidemia in Shenzhen City].
abstract: OBJECTIVE
  To investigate the association between different iodine nutrition and the prevalence of dyslipidemia in a representative sample of subjects in Shenzhen.
  
  
  METHODS
  A total of 326 adults from 2 different communities in Shenzhen were included in the study. A questionnaire, physical examination and laboratory test were given to all subjects. 317 questionnaires and blood samples were effective.
  
  
  RESULTS
  When the urine iodine concentration was less than 200 microg/L, there is a reverse relationship between iodine nutrition and prevalence of HDL-c (r(s) = - 0.164, P = 0.031). When the urine iodine concentration was higher than 300 microg/L, there is a positive relationship between iodine nutrition and prevalence of HDL-c (r(s) = 0.246, P = 0.013). There was no significant correlation between other lipid parameters and urinary iodine concentration. Multivariate Logistic regression analysis showed that high blood glucose and abdominal obesity were significantly related to the prevalence of dyslipidemia, urine iodine concentration was no significant correlation with the prevalence of dyslipidemia.
  
  
  CONCLUSIONS
  The prevalence of dyslipidemia in Shenzhen is high, there may be a U shaped relationship between iodine nutrition and the prevalence of abnormal HDL-c level.
