To measure the iodine nutritional status of island adults in Zhoushan, China.
A comparison study was carried out in eight villages. These were selected from iodized salt and non-iodized salt districts of Zhoushan island by random sampling. The Mann-Whitney test was used to compare the urinary iodine concentration and dietary iodine intake between the two districts.
The median of urinary iodine concentration in the non-iodized salt group was 90 micrograms/l, which was lower than 194 micrograms/l in the iodized salt group (u = 14.673; p < 0.000), whereas the median of daily dietary iodine intake in the two groups was 128 and 147 micrograms, respectively (u = 1.847; p = 0.065). There was no significant correlation between dietary iodine intake and urinary iodine concentration (p = 0.095).
Salt iodization is necessary. Special characteristics of the island diet should also be considered.
评估中国舟山岛成年居民的碘营养状况。
在八个村庄开展对比研究。这些村庄通过随机抽样从舟山岛的加碘盐地区和非加碘盐地区选取。采用曼-惠特尼检验比较两个地区的尿碘浓度和膳食碘摄入量。
非加碘盐组尿碘浓度中位数为90微克/升，低于加碘盐组的194微克/升（u = 14.673；p < 0.000），而两组每日膳食碘摄入量中位数分别为128微克和147微克（u = 1.847；p = 0.065）。膳食碘摄入量与尿碘浓度之间无显著相关性（p = 0.095）。
食盐加碘很有必要。还应考虑海岛饮食的特殊特点。
