目的了解甘肃省肃南牧区居民户碘盐食用情况,为消除碘缺乏病提供科学依据。方法按照《全国碘缺乏病监测方案》和《甘肃省碘缺乏病防治项目实施方案》的要求,2011─2015年随机抽取肃南县居民户食用盐测定盐碘含量。结果 2011─2015年共监测肃南县居民户盐样1 600份,合格1 557份,碘盐合格率97.66%,碘盐覆盖率99.85%,合格碘盐食用率97.52%,2015年检出非碘盐3份;盐碘均值28.5 mg/kg,其中盐碘含量<20 mg/kg检出21份、占1.31%,20~30 mg/kg检出1 023份、占64.06%,31~39 mg/kg检出529份、占33.12%,40~50 mg/kg检出17份、占1.06%,>50mg/kg检出7份、占0.45%;不同年份碘盐合格率(χ2=27.79)、合格碘盐食用率(χ2=48.49)差异有统计学意义(均P<0.05)。结论甘肃省肃南牧区碘盐普及状况良好,碘缺乏病各项措施得到有效落实,但仍需加大碘盐的监管力度,加强健康教育宣传,确保居民长期食用合格碘盐。
Objective To understand the consumption of iodized salt in households in Sunan pastoral area of Gansu Province and provide a scientific basis for eliminating iodine deficiency disorders. Methods According to the requirements of “National Iodine Deficiency Disease Surveillance Program” and “Implementation Plan of Iodine Deficiency Disorders Prevention and Control Project in Gansu Province”, salt iodine levels were determined randomly from 2011 to 2015 in households in Sunan County. Results From 2011 to 2015, a total of 1 600 salt samples were obtained from households in Sunan County, with 1 557 qualified samples, 97.66% qualified iodized salt, 99.85% iodized salt and 97.52% qualified iodized salt. In 2015, The average salt iodine value was 28.5 mg / kg, of which 21 were salt iodine <20 mg / kg, accounting for 1.31%, 1 023 were detected at 20-30 mg / kg, accounting for 64.06%, 31-39 The detection rate of iodized salt in different years (χ2 = 27.79 mg / kg, accounting for 33.12%, 17 (40%), 1.06% ), The consumption rate of qualified iodized salt (χ2 = 48.49) was significantly different (all P <0.05). Conclusion The prevalence of iodized salt in the pastoral areas of Sunan, Gansu province is good, and various measures of iodine deficiency disorders are effectively implemented. However, the supervision of iodized salt needs to be strengthened, and publicity of health education should be strengthened to ensure that residents have long-term consumption of qualified iodized salt.
