To measure the iodine nutritional status on adult islanders and to evaluate the advantages and disadvantages of iodized salt prophylactic programs.
A comparative study was carried out in 8 rural townships selected from Dinghai (iodized salt district) and Daishan (non-iodized salt district) of Zhoushan islands by random sampling method. Mann-Whitney test was used to compare the urinary iodine concentration and dietary iodine intake of the two groups. Spearman correlation test was used to look for the correlation of urinary iodine concentration and dietary iodine intake in the two groups respectively.
The amounts of daily iodine intake excluding the iodine intake from iodized salt in the two groups were 128 micro g and 147 micro g respectively but the difference was not statistically significant (u = 1.847, P = 0.065). The urinary iodine concentration of non-iodized salt group was 90 micro g/L, lower than 194 micro g/L in iodized salt group (u = 14.673, P = 0.000). There was no significant correlation between daily iodine intake and urinary iodine concentration (r(s) = 0.052, P = 0.095).
In Zhoushan islands, the daily iodine intake did not meet the daily need (150 micro g/day) suggesting that iodized salt supplement was necessary. However, side effect due to overdose should be brought into attention.
测定成年岛民的碘营养状况，并评估碘盐预防计划的优缺点。
采用随机抽样方法，在舟山群岛定海（碘盐区）和岱山（非碘盐区）选取的8个乡镇进行对比研究。采用曼-惠特尼检验比较两组的尿碘浓度和膳食碘摄入量。采用斯皮尔曼相关性检验分别寻找两组尿碘浓度与膳食碘摄入量的相关性。
两组不包括碘盐碘摄入量的每日碘摄入量分别为128μg和147μg，但差异无统计学意义（u = 1.847，P = 0.065）。非碘盐组的尿碘浓度为90μg/L，低于碘盐组的194μg/L（u = 14.673，P = 0.000）。每日碘摄入量与尿碘浓度之间无显著相关性（r(s) = 0.052，P = 0.095）。
在舟山群岛，每日碘摄入量未达到每日需求量（150μg/天），提示有必要补充碘盐。然而，应注意过量带来的副作用。
