Twenty-four-hour urine iodine and afternoon casual urine iodine were determined in children aged 7-14 years grouped into A, B, C, and D at two-year interval in the areas where iodized salt prophylaxis had been instituted. Results showed there was no significant difference between urine iodine values expressed in median of microgram/g Cr x creatinine coefficient and in microgram/24 hr, and the former was considered to reflect the real iodine value in urine. Urine iodine in children of groups C and D (older) was greater than of A and B (younger). Urine iodine reached the lower limit only in 51.2% of the children aged 13-14 years in Heba Township where iodized salt prophylaxis was instituted, with 75 micrograms iodine intake daily as lower limit. It suggested iodine deficiency remained a problem in that area.
在推行碘盐预防措施的地区，对7至14岁的儿童按A、B、C、D组每两年进行一次分组，测定其24小时尿碘和午后随机尿碘。结果显示，以微克/克肌酐×肌酐系数中位数表示的尿碘值与以微克/24小时表示的尿碘值之间无显著差异，且前者被认为能反映尿中真实碘值。C组和D组（年龄较大）儿童的尿碘高于A组和B组（年龄较小）。在推行碘盐预防措施的河坝乡，13至14岁儿童中仅51.2%的尿碘达到下限，每日碘摄入量下限为75微克。这表明该地区碘缺乏问题依然存在。
