摘要
目的 了解食用盐碘含量调整前（2011年）、后（2013年）广西防治碘缺乏病措施落实情况,评价人群碘营养情况,为今后防治工作提供依据.方法 收集广西食用盐含碘量调整前、后的碘盐、饮用水水碘和人群碘营养监测数据,比较食用盐含碘量调整前后的人群水碘、盐碘和尿碘的变化情况.结果 2011年和2013年对广西109个县（市、区）开展碘盐、水碘和人群碘营养监测工作.①水碘监测：2011年共检测水样4 968份,水碘中位数为2.69 μg/L.其中,＜10.00 μg/L的有4 210份,占84.74％.2013年检测水样7 554份,水碘中位数为2.11 μg/L.其中,＜10.00 μg/L的有6 512份,占86.21％.②盐碘监测：2011年,共检测食用盐盐样30 786份,盐碘中位数为32.30 mg/kg.经人口加权计算,全区碘盐覆盖率为98.31％,碘盐合格率为97.36％,合格碘盐食用率为95.98％.2013年,共检测食用盐盐样32 779份,盐碘中位数为24.94 mg/kg.经人口加权计算,碘盐覆盖率为98.36％,碘盐合格率为95.97％,合格碘盐食用率为94.49％.2011年和2013年盐碘比较差异有统计学意义（x2=17 830.03,P＜0.05）.③尿碘监测：2011年共检测尿样8 278份,尿碘中位数为241.10 μg/L.其中,＜ 100.00 μg/L的有889份,占10.74％;100.00～＜200.00 μg/L的有2 174份,占26.26％;200.00～＜300.00μg/L的有2 451份,占29.61％;≥300.00μg/L的有2 764份,占33.39％.2013年共检测尿样10 988份,尿碘中位数为200.35 μg/L.其中,＜100.00 μg/L的有1 716份,占15.62％; 100.00 ～＜ 200.00 μg/L的有3 745份,占34.08％;200.00～＜300.00 μg/L的有2 970份,占27.03％; ≥300.00 μg/L的有2 557份,占23.27％.2011年和2013年尿碘比较差异有统计学意义（x2=391.98,P＜ 0.05）.结论 广西属于低水碘地区,碘缺乏病防治现况达到了国家《碘缺乏病消除标准》.应继续完善广西科学补碘、持续消除碘缺乏病工作,保证广西居民处于适宜的碘营养水平.
Objective To understand the implementing situation of prevention measures for iodine deficiency disorders before （2011） and after （2013） the adjustment of salt iodine content in Guangxi,to evaluate the changes of iodine nutritional status,and to provide a basis for future prevention work.Methods Monitoring data of iodized salt,drinking water iodine and iodine nutritional status before and after the adjustment of iodine content of salt was collected.Changes in water iodine,salt iodine and urinary iodine before and after adjusting iodine content of salt were compared.Results The monitoring work of iodized salt,drinking water iodine and iodine nutritional status was carried out in all the 109 counties （cities,districts） in 2011 and 2013.①Drinking water iodine monitoring：a total of 4 968 water samples was tested in 2011,the median water iodine was 2.69 μg/L.Of which,4 210 water samples below 10.00 μg/L,the proportion was 84.74％.A total of 7 554 water samples were tested in 2013,the median water iodine was 2.11 μg/L.Of which,6 512 water samples below 10.00 μg/L,the proportion was 86.12％.②Iodized salt monitoring：a total of 30 786 salt samples were tested in 2011; the salt median iodine was 32.30 mg/kg.The iodized salt coverage rate was 98.31％,iodized salt qualification rate was 97.36％,and qualified iodized salt consumption rate was 95.98％ weighted by population.A total of 32 779 salt samples were tested in 2013; the salt median iodine was 24.94 mg/kg,the iodized salt coverage rate was 98.36％,iodized salt qualification rate was 95.97％,and qualified iodized salt consumption rate was 94.49％ weighted by population.The difference of salt iodine was statistically significant between 2011 and 2013 （x2 =17 830.03,P ＜ 0.05）.③Urinary iodine monitoring：a total of 8 278 urinary samples were detected in 2011; the median urinary iodine was 241.10 μg/L.Among these,889 urinary samples below 100.00 μg/L,the proportion was 10.74％; 2 174 urinary samples in 100.00 -＜ 200.00 μg/L,the
