摘要
在已经加碘盐防治地区，将７～１４岁儿童按２岁一组分为Ａ、Ｂ、Ｃ、Ｄ４组。分别测定受试者２４ｈ和下午一次随机尿碘值。经分析比较尿碘值的各种表示方法，看出４组儿童尿碘值采用随机尿碘ｕｇ／ｇＣｒ中位数值ｘ肌酐系数值表示方法与其尿碘ｕｇ／２４ｈ中位数值差异无显著性，因此，前者被认为是切合实际的尿碘表示方法。随着年龄增长Ｃ、Ｄ两组儿童２４ｈ尿碘值大于Ａ、Ｂ两组。若以４岁以上儿童碘供应量下限值为７５ｕｇ／ｄ为标准，河坝乡虽经加碘防治，但１３～１４岁儿童尿碘水平达下限值者仅占５１．２％，表明仍供碘不足。
wenty-fotir-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 pro-phylaxis had been instituted.ResuIts showed there was no significant difference between urine iodine values expressed in median of ug /g Crxcreatinine coefficient and in ug/24hr,and the forrner 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 (youriger).Urine iodine reached the lower limit oniy in 51.2%of the chil-dren aged 13～14 years in Heba Township where iodized salt prophylaxi;was instituted,with 75ug io-dine intake daily as lower limit. It suggested iodine deficiency remained a problem in that area.
