To evaluate the iodine nutritional status and its relation to iodized salt intake in child islanders.
A comparing study was carried out in 4 townships selected by random sampling from Dinghai (iodized salt) and Daishan(non-iodized salt) of Zhoushan island and total 592 of children were included in the study. The Mann-Whitney test was used to compare the urinary iodine concentration and dietary iodine intake of two groups. The correlation of urinary iodine concentration and dietary iodine intake were examined by Spearman correlation test. Ordinal regression was used to analyse the dependent variables of urinary iodine concentration.
The urinary iodine concentration of non-iodized salt district was lower than that in iodized salt district (87 microg/L compared with 150 microg/L, u=7.296, P=0.000) ,whereas the amount of daily iodine intake in the two groups was 34.5 microg/d and 62.3 microg/d (u=6.925, P=0.000). The urinary iodine concentration of 58.6 % children in non-iodized salt district was below 100 microg/L. Age and iodized-salt intake were significant factors in the final regression model (P<0.05) with the OR of 1.119 and 3.238, respectively.
The daily dietary iodine intake for children in Zhoushan island is insufficient, the iodized salt prophylaxis is necessary.
评估海岛儿童的碘营养状况及其与碘盐摄入量的关系。
采用随机抽样的方法，在舟山岛定海（碘盐）和岱山（非碘盐）选取4个乡镇进行对比研究，共纳入592名儿童。采用Mann-Whitney检验比较两组儿童的尿碘浓度和膳食碘摄入量。采用Spearman相关检验分析尿碘浓度与膳食碘摄入量的相关性。采用有序回归分析尿碘浓度的因变量。
非碘盐地区儿童的尿碘浓度低于碘盐地区（分别为87μg/L和150μg/L，u=7.296，P=0.000），而两组儿童的每日碘摄入量分别为34.5μg/d和62.3μg/d（u=6.925，P=0.000）。非碘盐地区58.6%的儿童尿碘浓度低于100μg/L。年龄和碘盐摄入量是最终回归模型中的显著因素（P<0.05），其OR值分别为1.119和3.238。
舟山岛儿童每日膳食碘摄入量不足，有必要进行碘盐预防。
