2005年我国居民户食用非碘盐状况分析

目的分析全国居民户食用非碘盐状况和非碘盐问题地区。方法盐碘检测采用GB／T13025．7—1999直接滴定法。非碘盐判定标准为盐碘〈5mg／kg；非碘盐问题地区判定标准为碘盐覆盖率〈90％。结果发现非碘盐问题省份7个；与2002年监测结果比较，非碘盐率上升的有13个省份；非碘盐问题地区新增加3个省份。调查出的3081份非碘盐样本中，以精制盐、粉碎原盐和其他盐种占居民户食用盐主导地位．其中非碘精制盐分布广泛，覆盖全国27个省份，其他非碘盐品种则呈区域性分布。结论无论是数量上还是分布上，非碘盐率均在增加，非碘盐问题较为严重，有些省份病情反弹与非碘盐问题密切相关，提示应对这些地区的非碘盐问题予以高度重视。

2007-2009年河北省居民户碘盐监测分析

Objective To find out the situation of household consumption of iodized salt in Hebei province so as to provide scientific basis for prevention and control of iodine deficiency disorders(IDD). Methods According to the "national iodine deficiency disorders surveillance program (Trial)", the county (city, district) was taken as a unit, township (town) and administrative villages were selected in accordance with the principle of systematic sampling, then households were chosen by random sampling to collect their edible salt in Hebei province from 2007 to 2009. Salt iodine content was detected by direct titration method. Results A total of 48 675, 48 448 and 48 756 salt samples were collected from 2007 to 2009, respectively. The consumption rate of qualified iodized salt from 2007 to 2009 was 91.16%, 91.96% and 96.17%, respectively. There were 24.6%(41/167)and 18.0%(30/167)counties with consumption rate of qualified iodized salt under 90% in 2007 and 2008, respectively. The percentage of counties with consumption rate of qualified iodized salt above 90% was 100.0%(167/167) in 2009. In general there was a significant differences in frequency distribution of consumption rates of qualified iodized salt among the three years(H = 10.778, P ＜ 0.01 ), and the difference was found significant between 2007 and 2009 as well as between 2008 and 2009(all P ＜ 0.05), but was not significant between 2007 and 2008(P ＞ 0.05). Conclusions The consumption rate of qualified iodized salt at household level increases annually from 2007 to 2009. By 2009,the consumption rate of qualified iodized salt in each county is more than 90%, which has reached the national standard stipulated in "the evaluation programs for fulfilling the goal of eliminating IDD at county level".

Abstract：

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.
