摘　　要：目的了解2019年陕西省碘缺乏病病情,为完善碘缺乏病消除防治策略提供理论依据。方法按《全国碘缺乏病监测方案(2016版)》对陕西省所辖110个县(市、区)进行碘缺乏病调查,采集儿童和孕妇即时尿样及食用盐样进行尿碘、盐碘含量检测,采用触诊法和B超法(抽取39个县区)进行学龄儿童甲状腺检查。结果本次共检测盐样34 656份,盐碘含量为24.06±3.68 mg/kg,碘盐覆盖率、碘盐合格率、合格碘盐食用率分别为99.94%(34 634/34 656)、97.62%(33810/34 634)、97.56%(33 810/33 656),不同地区间盐碘含量水平比较,差异有统计学意义(P<0.05);检测8~10岁学龄儿童尿样23 101份,尿碘中位数为221.56μg/L,不同地区、不同性别儿童尿碘水平比较,差异均有统计学意义(P<0.05);检测孕妇尿样11 555份,尿碘中位数为177.09μg/L,不同地区、不同孕期孕妇尿碘水平比较,差异均有统计学意义(P<0.05);共调查8~10岁学龄儿童23 101名,触诊检查甲状腺肿大254人,甲肿率1.10%,所有县区均低于5%,抽取39个县区8 191名学生进行甲状腺B超检测,甲状腺容积中位数为2.68 m L,不同地区、不同年龄间比较,差异有统计学意义(P<0.05)。结论合格碘盐食用率、儿童尿碘中位数及甲状腺肿大率等指标从省、市、县层面均达到国家碘缺乏病消除标准;12个县孕妇尿碘中位数在100~150μg/L间,应加强对孕妇等特需人群碘营养摄入的监测。Objective To understand the situation of iodine deficiency diseases( IDD) in Shaanxi,in 2019,so as to provide theoretical basis for improving the elimination and prevention strategies of IDD. Methods All 110 counties( districts) in Shaanxi were investigated for IDD.Instant urine samples and salt samples of children and pregnant women were collected for detection of urine iodine and salt iodine content. Palpation and B-ultrasound( 39 counties or districts were selected) were used to check the thyroid of school-age children.Results A total of 34 656 salt samples were detected,the average salt iodine was 24.06±3.68 mg/kg;The coverage rate,qualified rate and consumption rate of iodized salt were 99.94%( 34 634/34 656),97.62%( 33 810/34 634)and 97.56%( 33 810/33 656) respectively;Comparison of salt iodine levels between different regions,the difference is statistically significant( P<0.05).A total of 23 101 urine samples of children aged 8-10 were detected,the median of urine iodine was 221.56μg/L;Comparison of Urinary iodine levels between different regions and genders,the differences is statistically significant( P<0.05).11 555 urine samples of pregnant women were detected,the median of urine iodine was 177.09 μg/L;Comparison of urine iodine levels in pregnant women in different regions and pregnancy had statistical significance( P< 0.05). A total of 23 101 school-age children were investigated,254 cases of goitre were examined by palpation;The goitre rate was 1.10%,which was lower than 5%in all districts or counties;Choosing 8 191 students from 39 counties( districts) be examinod by B-ultrasound;The median thyroid volume was 2.68 mL;The difference were statistically significant when compared with different regions and ages( P< 0.05). Conclusions The qualified iodized salt consumption rate,the goiter rate of children and the median urine iodine of children have all reached the national standard of eliminating IDD from the provincial,city,and county levels;The median urine iodine of pregnant women in 12 counties w
