Objective To analyze monitoring results of iodized salt and distribution characteristics of problem areas with non-iodized salt in Gansu province during 2001 - 2009 and to provide a basis to develop countermeasures to iodine deficiency disorders. Methods According to the criterion of "The National Scheme of Iodized Salt Surveillance", two levels of monitoring were carried out on production and wholesale-level(during 2001 -2007) and household-level(during 2001 - 2009). Salt iodine was determined by direct titration method (GB/T13025.7-1999), and Sichuan salt or special salt was determined with an arbitration method. Criteria for qualified iodized salt was (35 ± 15)mg/kg(20 - 50 mg/kg), and for non-iodized salt was ＜ 5 mg/kg. Results During 2001 - 2007, a total of 4900 salt samples at production and wholesale-levels were examined, with a qualification rate of 97.80% (4792/4900). Non-iodized salt rates were all below 5% in Gansu province, consumption rate of qualified iodized salt was higher than 90% after 2003. During 2001 - 2009, cities(states) with non-iodized salt problems appeared 23 times, with Linxia accounting for 39.1%(9/23), Wuwei accounting for 21.7%(5/23). During 2001 -2009, counties(districts) with non-iodized salt problem appeared 123 times, including 68 times of ethnic minorities and state poverty counties, accounting for 55.3%(68/123). During 2001 - 2005 and 2006 - 2009, ethnic minorities and state poverty counties were accounting for 49.4%(44/89) and 70.6%(24/34) in counties with non-iodized salt problem. Conclusions The quality of iodized-salt at production and wholesale level is satisfactory in Gansu province, household consumption rate of qualified iodized salt have reached national standard for eliminating iodine deficiency disorders. But ethnic minorities and state poverty counties are main regions with non-iodized salt problem,these areas will be the key areas of prevention of iodine deficiency disorders in Gansu province in the future.

Objective To monitor the quality changes of iodized salt and analyze its impact factor in Chongqing between 2001 and 2009. Methods Salt samples were collected according to the east, west, south,north and center locations in iodized salt production, wholesale and household sectors. Two units in iodized salt production and wholesale segment were sampled from north, south, east and west places and only 1 unit was sampled from the central place. Nine samples were collected every month in each place. If the place had less than 9 units, and then taken all the units. About resident household, 2 townships were sampled from north, south, east and west places, and 1 township was sampled from the central place, then 20 samples were collected from each township. Iodine content was detected by oxidation-reduction assay. The index of mean iodine, qualified rate from factories and wholesale, coverage rate and taking rate of qualified iodized salt in residents were calculated.Significance was analyzed by trend test, analysis of variance and X2 test. Results The qualified rate of iodized salt from the manufacturers was 92.9%(13/14) in 2001 and the rate was 100.0% each year from 2002 to 2009. The qualified rates of iodized salt from the wholesale were 88.7%(282/318) - 99.8%(431/432). The rates of 2001 and 2002 were lower than that of other years(X2 = 4.98 - 45.69, all P< 0.05 or < 0.01). The coverage rate and taking rate of qualified iodized salt in residents were 94.2% (11 154/11 841 ) - 98.9% ( 14 061/14 217), 83.5% (9 887/11 841 ) -95.8% (13 449/14 039), respectively. The rates showed an increasing tendency (F = 9.27, 26.39, all P < 0.05).The districts(counties) with qualified iodized salt consumption rate > 90% kept increasing. The mean iodine from the manufacturers and wholesale were 29.71 - 36.25, and 31.26 - 36.13 mg/kg, respectively. The iodine level showed a descending trend(F = 35.45, 140.59, all P < 0.01 ). The mean iodine level from the inhabitants were 28.84 - 30.98 mg/kg which remained stable (F = 3.05, P > 0.05 ). The iodine level from manufacturers, wholesale to inhabitants showed an descending trend(F = 38.46 - 671.23, all P < 0.01 ). Conclusions The surveillance results of iodized salt shows an increasing tendency in quality of iodized salt, eoverage rate and taking rate of qualified iodized salt. Factors that affect the quality of iodized salt is that the enterprise does not add iodine to salt strictly by the standard.
