摘要
目的 了解碘盐新标准执行后海南省碘盐覆盖和重点人群碘营养情况.方法 2013年,将海南省的18个市（县、区）按海岸线和地形分布划分为东部沿海、西部沿海和内陆地区.在每个市（县、区）按东、南、西、北、中5个片区各抽取1个乡（镇、街道办事处）,每个乡（镇、街道办事处）抽取4个行政村（居委会）,每个行政村（居委会）抽检15家居民户收集家中食用盐,采用直接滴定法检测盐碘含量;每个行政村（居委会）抽取1所小学40名8～ 10岁儿童和孕妇、哺乳期妇女共20名,采集随意尿样,采用砷铈催化分光光度测定法检测尿碘.结果 共检测居民户盐样6 310份,盐碘中位数为25.9 mg/kg,碘盐覆盖率为97.92％（6 179/6 310）,合格碘盐食用率为95.47％（6 024/6 310）,非碘盐率为2.08％（131/6 310）.共检测8～ 10岁儿童尿样4 444份,尿碘中位数为165.4 μg/L,尿碘适宜（100～ 199 μg/L）的比例为49.3％（2 194/4 444）;检测孕妇尿样813份,尿碘中位数为126.6 μg/L,尿碘适宜（150～249 μg/L）的比例为33.6％（273/813）,尿碘＜150μg/L的比例为59.6％（485/813）;检测哺乳妇女的尿样1 286份,尿碘中位数为122.3 μg/L,尿碘适宜（≥100 μg/L）的比例为60.6％（779/1 286）.东部沿海、西部沿海、内陆地区的儿童（176.7、147.7、158.0 μg/L）、哺乳妇女（148.7、108.7、106.7μg/L）和孕妇（146.7、108.0、147.1μg/L）的尿碘中位数比较,差异均有统计学意义（H=34.70、26.76、35.95,P均＜ 0.01）.结论 孕妇的碘营养水平偏低,应加强此类人群的碘摄入量.
Objective To analyze the coverage of iodized salt and the focus population iodine nutrition after implementing new standard of iodized salt in Hainan Province.Methods Eighteen cities （counties,districts） were divided into eastern coastal,western coastal and inland areas according to coastline and terrain of Hainan Province in 2013.One township （town,street） was sampled from each city （county,district） in the east,the west,the south,the north and the center of these areas.Four villages （committees） and 15 households in each village （committee）,and 40 children aged 8-10 in one primary school,20 pregnant women and lactating women were sampled from each township （town,street）.Iodized salt samples collected from household were monitored by the method of direct titration;random urine samples of children aged 8-10,pregnant woman and lactating woman were tested by arsenic cerium catalytic spectrophotometry.Results Totally 6 310 edible salt samples were tested,and the median of salt iodine was 25.9 mg/kg.The coverage of iodized salt was 97.92% （6 179/6 310）.Residents＆quot; consumption rate of qualified iodized salt reached 95.47% （6 024/6 310）,and the rate of non-iodized salt was 2.08% （131/6 310）.About 4 444 urine samples of children aged 8-10 were examined,and the median of urinary iodine was 165.4 μg/L,in which suitable urinary iodine （100-199 μg/L） accounted 49.3% （2 194/4 444）;about 1 286 urine samples of lactating woman were examined,the median of urinary iodine was 122.3 μg/L,≥ 100 μg/L was 60.6% （779/1 286）;about 813 urine samples of pregnant woman were examined,the median of urinary iodine was 126.6 μg/L,59.6% （485/ 813） of this group were urinary iodine deficiency （〈 150 μg/L）.There were significant differences between the three groups in the east,the middle and the west areas of Hainan Province （children：176.7,147.7,158.0 μg/L,lactating women：148.7,108.7,106.7 μg/L,pregnant women：146.7,108.0,147.1 μg/L,H =34.70,26.76,35.95,all P 〈 0.01）.Conclusion The results have showed that pregnant woman are iodine deficiency,they should be given more iodine.
