根据1991～1992年中日联合调查小组在缺碘地区吉林省吉林市丰满区青山村,永吉县西阳乡马鞍山村,正常地区吉林省通输县四井子乡的调查结果,对病区448名和非病区132名7～14岁学生的甲状腺体积与年龄、身高、体重的关系进行分析研究。发现无论在长期供碘的地方性甲状腺肿病区,还是未供碘的非病区,甲状腺体积随着年龄、身高、体重的增长而增大,甲状腺体积y(ml)与年龄X_1(year)、身高X_2(cm)、体重X_3(kg)均呈中度正相关,具有显著的线性关系。回归方程为:病区青山村y=-1.6791+0.1433X_1+0.0197X_2+0.09X_3;病区马鞍山村y=-3.2254+0.2072X_1+0.0305X_2+0.0664X_3;非病区四井子乡y=4.6091+0.0842X_1-0.0588X_2+0.2358X_3。同时在不同外环境碘地区,在目前的碘营养水平上,外环境碘水平正常区学龄儿童甲状腺体积小于缺碘地区学龄儿童甲状腺体积;严重缺碘地区学龄儿童甲状腺体积大于中度缺碘地区学龄儿童甲状腺体积。
According to the survey results of the joint investigation team from 1991 to 1992 in Qingshan Village, Fengman District, Jilin Province, Ma’an Village, Xiyang Township, Yongji County, Jilin Province in the area of iodine deficiency, and the normal areas of Sichuan Province, The relationship between thyroid volume and age, height and weight of 132 non-ward students from 7 to 14 years old was analyzed. The results showed that thyroid volume increased with age, height and body weight in both endemic goiter and non-iodized non-endemic area, thyroid volume y (ml) and age X_1 (year) , Height X_2 (cm), weight X_3 (kg) showed a moderate positive correlation, with a significant linear relationship. The regression equation is as follows: WQMYYY = -1.6791 + 0.1433X_1 + 0.0197X_2 + 0.09X_3; WQMY = -3.2254 + 0.2072X_1 + 0.0305X_2 + 0.0664X_3; 0.0842X_1-0.0588X_2 + 0.2358X_3. At the same time, in the iodine area with different external environment, at the current level of iodine nutrition, thyroid volume of school-age children with normal iodine level in external environment is smaller than that of school-age children in iodine-deficient area; thyroid volume of school-age children with severe iodine deficiency is larger than that of medium iodine deficiency school Thyroid volume in children.
