摘要
2009年4月从吉林省磐石市宝山、明城、炯筒山3个乡抽取8～10岁儿童100名．并从其家庭中抽取18～45岁成人100名。另外，抽取孕妇、哺乳妇女及其0～2岁婴幼儿各50名。调查显示．居民户盐碘中位数为30．2mg／kg，水碘为2．8μg/L；依据世界卫生组织对人群尿碘中位数的评价标准，学龄儿童（196．5μg/L）、孕妇（198．5μg/L）、哺乳妇女（224．9μg/L）以及婴幼儿（209．0μg/L）的尿碘中位数均处于适宜水平，仅成人（269．0μg/L）达到了“超需要量”水平；B超测量学龄儿童甲状腺肿大率为1．8％。各类人群甲状腺功能异常率均较低，以亚临床甲状腺功能亢进（2．1％）、亚临床甲状腺功能减退（1．5％）、甲状腺功能亢进（1．2％）为主。亚临床甲状腺功能减退主要在成人（2．7％）、孕妇（1．7％）、哺乳妇女（1．8％）中流行，亚临床甲状腺功能亢进主要发生在学龄儿童（4．5％）及哺乳妇女（3．6％）人群中。提示当前吉林省农村地区居民碘营养水平对其甲状腺功能没有产生明显不良影响。
[ Summary] One hundred children aged 8-10 years and 100 adults aged 1845 from their families in three townships Baoshan, Mingcheng, and Yantongshan of Panshi city, Jilin province were selected in April 2009. In addition, 50 pregnant or lactating women, and their 50 infants aged 0-2 years were selected. The median level of iodine in salt at household was 30.2 mg/kg and that of drinking water was 2.8 μg/L. The median levels of urine iodine in school age ehihtren （ 196.5 μg/L）, during pregnancy （ 198.5 μg/L）, lactation （ 224.9μg/L ）, and in infants （209.0 μg/L） all were optimal according to World Health Organization criteria. Only the median urine iodine in adults （269.0 μg/L） was more than adequate. The prevalence of goiter evaluated by B-ultrasound was 1.8% in 8-10 year-old children. The incidences of various thyroid dysfunctions were low in these residents, such as subclinical hyperthyroidism （ 2.1% ） , subclinical hypothyroidism （ 1.5% ） , and hyperthyroidism （ 1. 2% ）. Subclinical hypothyroidism occurred mostly in adults （2.7%）, pregnant women（ 1.7% ）, and lactating women（ 1.8% ） ; and subclinical hyperthyroidism occurred mostly in 8-10 years old school children （4.5%） and lactating women （3.6%）. These results show that the current iodized salt content has no harmful effect on thyroid function of rural residents in Jilin province.
