对安徽大别山、巢湖缺碘病区和合肥市共３７５９例儿童在全民食盐加碘前的碘营养、垂体—甲状腺轴功能状态进行研究。结果表明：巢湖组为重病区（肿大率为５５．８％），儿童人群严重缺碘（尿碘中位数为１９．２μｇ／Ｌ），垂体—甲状腺轴功能呈高代偿状态，有亚临床甲状腺功能减退存在。大别山组，尿碘（中位数２６９．１μｇ／Ｌ）虽高，但甲肿率为２２．４％，为中等病区水平，且垂体—甲状腺轴功能呈代偿状态，也提示有亚甲减存在，而合肥市甲肿率低，各项功能正常，为非病区，但尿碘水平偏低，提示碘营养不足。显示了全民食盐加碘防治的必要性。
A total of 3759 children in the Dabie Mountains of Anhui Province, the Iodine Ward in Chaohu Lake and Hefei City were studied for their iodine nutrition and pituitary-thyroid axis status before salt iodization. The results showed that the Chaohu group was seriously ill (swollen rate was 55.8%), children with severe iodine deficiency (median of urinary iodine was 19.2μg / L), and pituitary-thyroid axis function was highly compensated Subclinical hypothyroidism exists. Dabieshan group, urinary iodine (median 269.1μg / L) although high, but the rate of goiter was 22.4%, for the ward level, and pituitary-thyroid axis function compensated, but also suggest that methylene However, the rate of hypothyroidism in Hefei is low and all the functions are normal. It is non-ward, but the level of urinary iodine is low, suggesting that iodine deficiency is not enough. Shows the need for prevention and treatment of salt iodization of the whole people.
