午后任意一次尿的含碘量,不论以肌酐系数折算或以μg/L 表示,其几何均值与24小时尿碘实际排出量比较接近,而且尿碘值等级的频数分布也比较一致;不论成人或儿童,其午后任意一次尿碘测定值与当日的24小时尿碘排出量的等级符合率都在31～39%之间,μg/L 表示法的符合率略高于肌酐折算法,但无明显差异。作者认为:对7—14岁岁儿童在监测甲状腺肿大率的同时,采集午后任意一次尿,测定碘含量,以μg/L 表示,在防治监测工作中有更大的可行性,建议国家尽快地制订出与之相适应的正常值判定标准,以便付诸实施。
The afternoon urine iodine content of any urine, regardless of creatinine conversion or in μg / L, the geometric mean and 24-hour urinary iodine actual discharge is relatively close, and urinary iodine value frequency distribution is more consistent; both adults or Children, the afternoon of any determination of urinary iodine and the day of 24-hour urinary iodine emission levels were in line with the rate of 31 to 39%, μg / L means that the agreement was slightly higher than the creatinine conversion method, but no significant difference. The authors believe that: the children of 7-14-year-old in the monitoring of goiter rate at the same time, the afternoon to collect any urine, determination of iodine, expressed in μg / L, in the prevention and control work has more feasibility, it is recommended that the state as soon as possible In accordance with the normal development of a standard judgment, in order to put into practice.
