为评估山东省碘缺乏病防治现状与消除进程 ,1995、1997和 1999年三次进行了碘缺乏病 PPS抽样调查。结果发现 ,加碘盐生产和零售单位的盐碘含量中位数均在正常范围内 ,碘盐合格率逐年升高 ;居民户盐碘含量中位数由 0分别升至 2 3.3和 2 8.6 ( mg/ kg) ,合格率由 32 .3%升至 6 3.3%和 79% ,非碘盐主要来源于大粒粗盐 ;尿碘中位数及大于10 0μg/ L的比例分别为 2 34 .1μg/ L和 75 .8%、45 3μg/ L和 96 .7%、2 6 7.3μg/ L和 86 .5 % ;甲状腺肿大率 ,触诊结果由2 6 .3%降至 7.6 %和 13.2 % ,B超结果后两次为 7.6 %和 7.8% ;新生儿 TSH大于 5 m IU/ L 的比例为 2 6 .3%、2 7.7%和2 8.9% ;健康教育答卷及格率稳定在 85 .7%和 87%。表明我省 IDD防治效果显著 ,但非碘盐仍然存在 ,应加大健康教育力度 ,提高合格碘盐覆盖率
To assess the status of iodine deficiency disorders in Shandong Province and the elimination process, three surveys of iodine deficiency disorders (PPS) were conducted in 1995, 1997 and 1999. The results showed that the iodine content of iodized salt production and retail units were within the normal range and the passing rate of iodized salt increased year by year. The median of salt iodine content of household increased from 0 to 23.3 and 22.66 respectively mg / kg). The passing rate increased from 32.3% to 6 3.3% and 79% respectively. The non-iodized salt mainly came from coarse grain coarse salt. The median of urinary iodine and the proportion of more than 100μg / L were respectively 2 34.1μg / L and 75.8%, 45.3μg / L and 96.7%, 26.37μg / L and 86.5% respectively. The rate of goiter and palpation decreased from 26.3% to 7.6% and 13.2% respectively % And 7.6% and 7.8% respectively after two times of B-ultrasound results. The proportion of newborns with TSH> 5 m IU / L was 26.3%, 2 7.7% and 2.89%. The passing rate of health education questionnaire remained stable at 85%. 7% and 87%. That IDD prevention and treatment of our province significant effect, but non-iodized salt still exists, should increase health education, improve the coverage of qualified iodized salt
