To contribute evidence relevant to the policy of supplying iodised salt (IS), non-iodised salt (NIS) or both in Chinese cities.
Subnational telephone interview survey.
China.
Totally, 24 557 telephone numbers were dialled and 4833 citizens accepted the telephone interview. The telephone numbers were randomly selected by random digit dialling and a Mitofsky-Waksberg two-stage sampling method in 17 capital cities and 6 coastal cities from 17 iodine deficiency disorder (IDD)-eliminated provinces (municipalities).
The 4833 citizens finished the telephone interview. Among them, 3738 (77.3%) citizens chose IS, 481 (10%) citizens chose NIS, and the others chose both IS and NIS. The citizens' awareness rates of IDD and IDD preventive measures were 68.7% and 62.5%, respectively.
It is not a suitable time to supply IS and NIS simultaneously in the developed cities of China, but a pilot project may be conducted in the cities where IDD has been sustainably eliminated, there is strong awareness of IDD and the population can make informed decisions regarding IS. IDD health education should be further strengthened, especially regarding the potential for IQ damage.
为中国城市供应碘盐（IS）、非碘盐（NIS）或两者兼有的政策提供相关证据。
省级以下电话访谈调查。
中国。
共拨打24557个电话号码，4833名市民接受了电话访谈。电话号码通过随机数字拨号以及米托夫斯基-瓦克斯伯格两阶段抽样方法，从17个已消除碘缺乏病（IDD）省份（直辖市）的17个省会城市和6个沿海城市中随机选取。
4833名市民完成了电话访谈。其中，3738名（77.3%）市民选择碘盐，481名（10%）市民选择非碘盐，其余市民选择碘盐和非碘盐两者。市民对碘缺乏病及其预防措施的知晓率分别为68.7%和62.5%。
在中国的发达城市，同时供应碘盐和非碘盐的时机尚不成熟，但在已持续消除碘缺乏病、对碘缺乏病有较强认知且居民能够对碘盐做出明智决策的城市，可以开展试点项目。应进一步加强碘缺乏病健康教育，尤其是关于智商损害可能性的教育。
