舟山群岛居民碘营养状况调查分析

目的调查舟山海岛地区居民的碘营养状况，并评价食盐加碘的利弊。方法根据整群随机抽样法对舟山海岛居民进行流行病学问卷调查和尿碘测定；对相应地区8～10岁儿童行尿碘检测。结果舟山海岛地区成年居民尿碘中位数（MUI）总体为226．0ug／L，其中城镇居民320．7ug／L、盐民122．2ug／L、农民188．9ug／L、渔民193．6ug／L、普陀山僧侣271．7ug／L；相应地区8～10岁城镇儿童MUI为259．0ug／L、盐民儿童123．71．1g／L、农民儿童130-9ug／L；女性尿碘水平显著低于男性（P〈0．05），是否食用加碘盐和海产品与尿碘的差异有统计学意义（均P〈0．05），而年收入、是否食用蔬菜水果、吸烟、饮酒、饮茶与尿碘水平的差异则均无统计学意义（均P〉0．05）。结论舟山海岛地区碘营养适量，居民食用海产品较多，不需食用加碘盐；食盐加碘和经常食用海产品可有效提高尿碘水平，舟山地区实施全民食盐加碘的措施值得商榷。
