Results The median salt iodine was 27.5 mg/kg and the coverage of iodized salt was 97.9%. 1 042 urine samples were collected from the five different cohorts and the medians urinary iodine were 286.7? 187.6?
Methods In this paper,the method of PPS was used to test 8~10 years children in 30 areas of goitre rate,urinary iodine,iodized salt qualified rate in inhabitants,TSH levels in neonates and healthy education survey of students and household women.
Results The median of iodized salt in household consuming was 34.9 mg/kg, the rate of qualified iodized salt was 87.2%, variation coefficient of iodized salt was 26.8%, the proportion of high concentrate iodine salt (> 60 mg/kg or >50 mg/kg) was significantly lower than the third surveillance.
Methods:Selecting five surveys according to the various directions and randomly selecting the children among 8~10 years old. Checking the goiter,urine indine and iodine salt,investigation of health awareness was made in the grade 5 students and housewives of 20~50 years old.
Conclusions Although the iodine salt supply and IDD situation are basically stable and the crowd urinary iodine level dropped to the more ideal level, there still exists non iodine salt selling market in Guangdong coastal areas and the pearl river delta and the level of salt iodine and urinary iodine in some areas is on the high side.
Methods By using sampling investigation, three countries were selected in Yan’an, pupils’ thyroids were examined by palpation and B-ultrasonograph; pupils and women were determined of their urinary iodine and the iodine salt in families; the students in the fifth grade and women of childbearing age and examined 6 ～ 14 year-old pupils’IQ.
It will be helpful for us to judge whether this area is insufficient in iodine and universal iodized salt is necessary or not.
The data reflected that water and soil iodine in foreland area was not high, which suggests universal iodized salt should be necessary.
Iodine concentration in canteen meals prepared with or without iodized salt
In each of two university canteens differing in the use (canteen A) or non-use (canteen B) of iodized salt for food preparation, 15 mostly equal lunch meals were collected for iodide and NaCl analysis.
Consequently, the use of iodized salt in central catering seems to play a more important role in a sufficient I intake than assumed so far.
