摘要
目的了解四川省重点人群碘营养状况,为科学补碘及防治措施调整提供依据。方法2018-2022年,采用分层整群随机抽样法,在四川省21个县(区),每个县(区)按东、西、南、北、中划分为5个片区,每个片区抽取1个乡镇(街道)作为监测点,每个监测点抽取8~10岁儿童40人,孕妇、育龄妇女、哺乳期妇女及其婴幼儿(0~2岁)各20人,采集其家庭食用盐盐样和尿样,进行盐碘、尿碘检测。使用B型超声法进行儿童甲状腺检查。结果共采集食用盐盐样52019份,其中合格碘盐50084份,合格碘盐食用率为96.3%,盐碘中位数为27.1 mg/kg。共检测儿童尿样21021份,尿碘中位数为199.5μg/L;孕妇尿样10293份,尿碘中位数为172.6μg/L;育龄妇女尿样10502份,尿碘中位数为174.4μg/L;哺乳期妇女尿样10444份,尿碘中位数为164.9μg/L;婴幼儿尿样10442份,尿碘中位数为191.9μg/L。共对21028名儿童进行甲状腺检查,甲状腺肿大率为1.8%(370/21028)。结论2018-2022年四川省重点人群碘营养处于适宜水平,持续保持碘缺乏病消除状态。
Objective To study the iodine nutrition status of key populations in Sichuan Province,so as to provide a basis for scientific supplementation of iodine and adjustment of prevention and control measures.Methods From 2018 to 2022,the stratified cluster sampling method was used in 21 counties(district)in Sichuan Province.Each county(district)was divided into 5 areas based on east,west,south,north,and center.One township(street)was selected as a monitoring site from each area.Forty children aged 8-10 years old and 20 pregnant women,women of childbearing age,lactating women,and their infants and young children(0-2 years old)were randomly selected from each monitoring site.Household edible salt and urine samples were collected for salt and urine iodine testing.B-ultrasound method was used for thyroid examination in children.Results A total of 52019 samples of edible salt were collected,including 50084 qualified iodized salt samples.The qualified iodized salt consumption rate was 96.3%,and the median salt iodine was 27.1 mg/kg.A total of 21021 urine samples from children were tested,with a median urine iodine level of 199.5μg/L.A total of 10293 urine samples were taken from pregnant women,and the median urine iodine level was 172.6μg/L.A total of 10502 urine samples were taken from women of childbearing age,with a median urine iodine level of 174.4μg/L.A total of 10444 urine samples were taken from lactating women,and the median urine iodine level was 164.9μg/L.There were 10442 urine samples from infants and young children,and the median urine iodine level was 191.9μg/L.A total of 21028 children underwent thyroid examination,with a goiter rate of 1.8%(370/21028).Conclusion From 2018 to 2022,the iodine nutrition of key populations in Sichuan Province is at an appropriate level,and the elimination of iodine deficiency disorders continues to be maintained.
