南通地区距海不同区域人群碘营养不良状况分析

ANALYSIS OF IODINE MALNUTRITION AMONG THE PEOPLE WHOSE DISTANCE IS DIFFERENT FROM THE SEA

本文通过对南通地区距海不同区域的275个乡(镇)1363名8～10岁儿童甲状腺肿大情况检查,并随机抽取上述儿童360份尿样作尿碘测定,及对1993～1995年出生的24839名新生儿脐带血作促甲状腺素(TSH)检测,调查结果均表明南通虽为沿海地区,但人群碘的摄入量不足。距海大于50公里地区人群与距海小于50公里地区人群在甲状腺肿大率、低尿碘分布频数比率、新生儿脐带血TSH值异常增高方面,均有显著性差异(P<0.01)。本文提示了碘营养不良状况的严重程度与距海距离有关。

In this essay the goitre is examined among 1363 children aging from 8 to 10 in 275 towns of the coastal area in Nantong City and the Iodine test of 360 urine samples chosen randomly from the above -mentioned children is also done. Besides, the TSH of umbilical cord blood of 24839 newly-born babies during October, 1993 and October,1995 is made. The results of the three examination and tests showed that the amount of Iodine taken in by the people in the coastal area in Nantong City is not sufficient.The differences can easily be seen in goitre rate, and the amount of Iodine in urine and the TSH of umbilical cord blood of newly-born babies among those who live more than 50 kilometres away from the coast, and those who live less than 50 kilometres away from the coast. This essay indicates the relationship between the degree of esverity of Iodine malnutrition and the distance to the coast.
