摘　　要：目的了解平顶山市居民碘盐质量和8—10岁儿童、孕妇和哺乳期妇女碘营养现状，为科学制定干预策略提供依据。方法按东、西、南、北、中5个方位，2013年采集居民家中盐样进行盐碘测定；采集8—10岁儿童、孕妇和哺乳期妇女尿样各40份，进行尿碘测定。盐碘测定采用直接滴定法，尿碘测定采用硫酸铵消化-砷铈催化分光光度法。结果检测居民户家中盐样1500份，盐碘中位数为27．5mg／kg。碘盐覆盖率为98．26％，碘盐合格率为94．09％，合格碘盐食用率为92．46％；8—10岁儿童尿碘中位数为164．92ug／L。尿碘〈50ug／L的占6．69％（17／254），与2011年8—10岁儿童尿碘〈50ug/L的16．41％（128／780）比较，差异有统计学意义（r=15．01，P〈0．05）；孕妇尿碘中位数为151．87ug／L，尿碘〈150ug／L的比例为48．59％（121／249）；哺乳期妇女尿碘中位数为145．32ug/L，尿碘〈100ug／L的比例为29．07％（66／227）。结论平顶山市碘盐质量和碘营养调查的各项指标继续保持“国家消除碘缺乏病标准”。8～10岁儿童、孕妇和哺乳期妇女碘营养现状总体上是适宜的，但要关注重点人群对碘的需求。Objective To understand the quality of iodized salt of the residents of Pingdingshan City, and the iodine nutritional status of children from 8-10 years of age, pregnant women and lactating women, and provide basis for intervention strategies. Methods At the east, west, south, north and the middle five directions of the city, residents＇ salt samples were gathered to determine the amount of iodine salt. The samples of urine were collected from 40 children （ 8-10 years of age）, 40 pregnant women and 40 lactating women,for the assay of urinary iodine. Salt iodine was determined by direct titration, urinary iodine was measured using ammonium sulfate digestion-arsenic cerium catalytic spectrophotometry. Results The salt samples of 1500 households were tested, and the median of salt iodine was 27.5 mg/kg, the iodized salt popularizing rate is 98.26% ,the qualification rate of iodized salt was 94.09% ,the qualified edible rate of iodized salt was 92.46% ; the median of urinary iodine of children aged 8-10 was 164.92 ug/L. The ratio of urinary iodine 〈50 ug/L was 6. 69% （ 17/ 254） ; compared with the urinary iodine 〈50 ug/L （16. 41% ） of children from 8-10 years of age in 2011, the difference was statistically meaningful （ X2 = 15.01 ,P〈0.05） ; The median of pregnant women＇s urinary iodine was 151.87 ug/L, the ratio of urinary iodine 〈150 ug/L to the urinary iodine 〉150 ug/L was 48.59% （121/249） ; The median of lactating women＇s urinary iodine was 145.32 ug/L,and the ratio of urinary iodine 〈100 ug/L to the urinary iodine 〉100 ug/L was 29.07% （66/227）. Conclusion The indicators of the quality of iodized salt and iodine nutrition survey of Pingdingshan City continuously maintained the ＂national standard of eliminating iodine deficiency＂. On the whole, the iodine nutritional status of children from 8-10 years of age, pregnant women and lactating womens＇ need of iodine was appropriate. However, special concern should be put on the iodine-need for the key groups.
