摘要
目的评价辽宁省居民碘营养状况,为制订碘缺乏病精准防治策略和措施提供科学依据。方法依据全国碘缺乏病监测方案,2017-2019年辽宁省在100个县(市、区)开展重点人群碘营养状况横断面调查。每个县(市、区)划为东、西、南、北、中5个片区,每个片区随机抽取1个乡镇(街道),每个乡镇(街道)抽取1所小学,每所小学抽取8~10岁非寄宿制儿童40人和孕妇20人,儿童采用超声法测量甲状腺各径向大小,计算容积(ml),儿童和孕妇均采集家庭食用盐样品和一次随机尿样检测盐碘和尿碘。结果2017-2019年辽宁省儿童食用盐含碘量分别为(23.7±4.8)mg/kg、(23.8±4.9)mg/kg、(23.8±4.3)mg/kg,碘盐覆盖率分别为98.4%(20044/20371)、98.3%(19881/20230)、98.8%(19978/20211),合格碘盐食用率分别为94.0%(19146/20371)、93.5%(18905/20230)、95.8%(19357/20211),尿碘中位数分别为167.8μg/L、165.1μg/L、165.9μg/L,甲状腺肿大率分别为1.9%(361/19401)、1.5%(229/15151)、1.5%(311/20211);孕妇食用盐含碘量分别为(23.9±4.6)mg/kg、(23.9±4.7)mg/kg、(24.3±4.1)mg/kg,碘盐覆盖率分别为98.5%(10019/10172)、98.3%(9839/10007)、99.1%(9926/10019),合格碘盐食用率分别为85.3%(8673/10172)、84.0%(8409/10007)、88.4%(8852/10019),尿碘中位数分别为141.7μg/L、133.3μg/L、148.6μg/L。结论2017-2019年辽宁省8~10岁儿童碘营养状况均处于适宜水平,孕妇处于碘缺乏水平。
Objective To evaluate the iodine nutrition status of residents in Liaoning Province and provide scientific basis for the formulation of precise prevention and control strategies and measures of iodine deficiency disorders(IDD).Methods Every year a cross-sectional survey on iodine nutrition status of children and pregnant women was carried out in 100 counties(districts)of Liaoning Province from 2017 to 2019.Five townships(community)were randomly selected according to their sub-area positions of East,West,South,North and center,1 primary school was randomly selected in each township(community),40 non-boarding students aged 8-10 were selected from each school.The radial size of the thyroid was measured by ultra-portable doppler diagnostic ultrasound system and the volume was calculated.Twenty pregnant women were randomly selected in each township(street).Collected their salt and random urine samples,tested salt iodine leve1 and urinary iodine leve1.Results From 2017 to 2019,the mean of salt iodize content of children’s family in the evaluation of residents’iodine nutrition status in Liaoning Province was 23.7±4.8 mg/kg,23.8±4.9 mg/kg and 23.8±4.3 mg/kg,the iodized salt coverage rate was 98.4%(20044/20371),98.3%(19881/20230)and 98.8%(19978/20211),and the consumption rate of qualified iodized salt was 94.0%(19146/20371),93.5%(18905/20230)and 95.8%(19357/20211),respectively.The MUI of children was 167.8μg/L,165.1μg/L and 165.9μg/L,respectively.And children’s goiter rate was 1.9%(361/19401),1.5%(229/15151)and 1.5%(311/20211),respectively.The mean of salt iodine content of pregnant women was 23.9±4.6 mg/kg,23.9±4.7 mg/kg and 24.3±4.1 mg/kg,respectively.The iodized salt coverage rate was 98.5%(10019/10172),98.3%(9839/10007)and 99.1%(9926/10019),and the consumption rate of qualified iodized salt was 85.3%(8673/10172),84.0%(8409/10007)and 88.4%(8852/10019),respectively.The MUI of pregnant women was 141.7μg/L,133.3μg/L and 148.6μg/L,respectively.Conclusions From 2017 to 2019,8-10 years old children’s urinary iodine was at an adequate level,but the pregnant women were in iodine deficiency.
