大学新生碘营养状况调查分析

A survey on the nutritional status of iodine in the frosh of Guangdong

调查广东药学院９６级新生１８９人，测定受试者尿碘值及血清甲状腺素（Ｔ４）含量，同时通过问卷了解其１６项相关因素。比较沿海大中城市、沿海村镇、内陆大中城市和内陆村镇来源新生的碘营养情况，了解广东省内各地居民的碘营养水平。结果如下：尿碘值中位数为３４４．５０μｇ／Ｌ，低于１００μｇ／Ｌ者占１２．１４％；沿海大中城市的新生缺碘率（２２．６％）高于其它地区（χ２＝７．９４，Ｐ＜０．０５）。血清Ｔ４的含量为１０７．９３±５１．３４ｎｍｏｌ／Ｌ，在参考正常值５４～１７４ｎｍｏｌ／Ｌ范围内者占８２．８％。问卷结果表明省内有较多居民常吃海产品，除海带和紫菜外，内地显著低于沿海地区（Ｐ＜０．０１）。食用加碘盐普及率７７．９９％，但沿海地区普及率（６９．６％）低于内地（９０．５％）。曾接受过碘剂防治者仅占总数的３．８３％。

お survey on the nutritional status of iodine in the 189 frosh of preventive medical department in Guangdong pharmacy college was carried out.The urinary iodine and the serum thyroxine (T4) were determined.Meanwhile,an investigation about the iodine nutrition was carried out with an asking paper.Comparing the urinary iodine and thyroxine(T4) of the students who come from coastal city,coastal countryside,inland city and inland countryside,we expect to estimate the iodine nutritional status in all popualtions of Guangdong.The median of urinary iodine is 344.50μg/L and the proportion of students with urianry iodine less that 100μg/L is 12.14%.The ratio of the students from coastal city whose urinary iodine is <100μg/L is significantly higher than that from other places (χ2=7.94,P<0.05).The serum thyroxine (T4) level is 107.93±51.34nmol/L(x±s).There are 82.8% students in the recommended range 54￣174nmol/L.The asking paper results indicate that consumption of sea foods in inland areas is less than costal areas except kelp and laver (χ2=10.65,P<0.01).There are 77.99% families consumed the iodine fortified salt,but coastal areas (69.6%) are less than inland areas (90.5%).Of total frosh,3.83% students had been treated with iodine preparation.
