摘要
目的 了解杭州市碘盐浓度调整对孕期妇女碘营养水平的影响，为孕期妇女科学补碘提供依据。方法2012—2014年，每年在杭州市的13个县（区、市）按人口容量概率比例抽样法抽取300户居民采集家中食用盐盐样，检测盐碘含量。每年在每个县（区、市）抽取100名孕妇，采集尿样，检测尿碘含量。结果2012—2014年杭州市分别抽检3904、3900、3900户居民食用盐盐样，盐碘中位数分别为23．77、22．75、23．30mg／kg，碘盐合格率分别为95．87％（3550／3703）、97．04％（3510／3617）、96．53％（3564／3692），合格碘盐食用率分别为90．92％（3550／3904）、90．01％（3510／3900）、91-38％（3564／3900）。2012—2014年，分别采集1300、1217、1315份孕妇尿样，尿碘中位分别为119．90、136．40、124．00μg／L。结论盐碘含量调整后，杭州市孕期妇女家庭盐碘食用水平稳定，但尿碘水平偏低应引起注意。
Objective To explore the impact of iodine nutrition on pregnant women after adjusting the iodine content in iodized salt in Hangzhou and provide a scientific basis for supplementation of iodine to pregnant women. Methods After adjusting the iodine content of salt from 2012 to 2014, proportional probability sampling method was used to select 300 families and 100 pregnant women from every county （area, city） of Hangzhou City, and the household salt and urine samples were collected to detect iodine. Results Totally 3 904, 3 900 and 3 900 samples of household salts were collected with the medians of salt iodine concentration of 23.77, 22.75 and 23.30 mg/kg of each year from 2012 to 2014, respectively. The qualified rate of iodized-salt was 95.87% （3 550/3 703）, 97.04% （3 510/3 617） and 96.53% （3 564/3 692） and the consuming rate of qualified iodized salt was 90.92% （3 550/3 904）, 90.01% （3 510/3 900） and 91.38% （3 564/3 900）, respectively, from the year 2012 to 2014. Totally 1 300, 1 217 and 1 315 urine samples of pregnant women were collected and the median of urinary iodine （MUI） of each year from 2012 to 2014 was 119.90, 136.40 and 124.00 μg/L, respectively. Conclusion After adjusting the iodine content of salt in Hangzhou, the salt iodine consumption levels of pregnant women＇s family are stable, but the level of urinary iodine is low, which should be pay attention to.
