目的了解重庆市居民碘盐普及情况和质量,巩固重庆市消除碘缺乏病目标成果。方法按照《全国碘缺乏病监测方案》,监测所有区县,每个区县按东西南北中抽取5个乡镇,每个乡镇4个村,每个村15户居民,采用直接滴定法测定盐碘。结果全市共监测190个乡镇,11 556份,碘盐11 515份、合格碘盐11 062份、非碘盐41份。碘盐中位数27.8 mg/kg,碘盐覆盖率、碘盐合格率、合格碘盐食用率、非碘盐率分别为99.60%、96.24%、95.87%、0.40%,结论重庆市碘盐保持在国家要求的消除碘缺乏病标准之上(碘盐覆盖率、碘盐合格率、合格碘盐食用率必须﹥90%),符合国家要求,但也存在不合格碘盐和非碘盐。

Methods According to “National Iodine Deficiency Disease Surveillance Program”, 5 counties, 4 villages in each township and 15 households in each village were sampled from all districts, counties and counties. Salt iodine was measured by direct titration . Results The city monitored a total of 190 townships, 11 556, 11 515 iodized salt, 11 062 qualified iodized salt and 41 non-iodized salt. The median of iodized salt was 27.8 mg / kg, the coverage of iodized salt, the qualified rate of iodized salt, the rate of qualified iodized salt and the rate of non-iodized salt were 99.60%, 96.24%, 95.87% and 0.40% respectively. The national requirements for eliminating iodine deficiency disorders on the standard (iodized salt coverage, qualified rate of iodized salt, qualified iodine salt consumption rate must be> 90%), in line with national requirements, but there are also substandard iodized salt and non-iodized salt.
