摘要
目的了解重庆市孕妇与新生儿的碘营养状况,为开展针对重点人群的碘缺乏防治提供依据。方法于2017年在重庆市选取26个区、县,每个区县按东、西、南、北、中划分5个抽样片区,在每个片区各随机抽取1个乡镇/街道,在所抽取的5个乡中每乡抽取20名孕妇,采集孕妇尿液样品,同时采集其家中的食盐样品。采用与妇幼部门合作的方式,收集监测县300名新生儿甲状腺功能低下筛查情况。结果共监测孕妇家庭食用盐2 608份,其中碘盐2 601份,合格碘盐2 433份,非碘盐7份。碘盐覆盖率、合格率、合格碘盐食用率、非碘盐率分别为99.73%、93.54%、93.29%、0.27%。各监测区县碘盐均数在22.80～31.60 mg/kg之间,总体均数为26.00 mg/kg。孕妇尿碘共监测2 608人,尿碘中位数为171.90μg/L,孕妇在孕早期的尿碘水平高于孕中期和孕晚期。22个区县新生儿甲状腺功能低下共筛查23 830人,促甲状腺激素升高198人,检出率为0.83%。结论孕妇合格碘盐食用率、尿碘中位数等各项指标均达到国家消除碘缺乏病标准,重庆市持续保持消除碘缺乏病状态。但部分地区仍存在非碘盐和不合格碘盐及孕妇碘营养不足的情况,有缺碘的风险。
Objective To understand the status of iodine nutrition in pregnant women and newborns in Chongqing and provide evidence for the prevention and treatment of iodine deficiency in key populations.Methods Twenty-six districts and counties in Chongqing in 2017 were selected for the study.Each district/county was divided into five sampling areas according to the east,west,south,north,and middle,and one town/street was randomly selected from each area.20 pregnant women from each of the 5 townships were selected to collect urine samples from pregnant women and collect salt samples from their homes.In cooperation with the maternity and childcare departments,300 cases of prenatal screening for neonatal hypothyroidism were collected.Results A total of 2608 edible salt samples for pregnant women were monitored, including 2601 iodine salt samples,2433 qualified iodine salt samples,and 7 non-iodized salt samples.Iodized salt coverage,pass rate,acceptable iodized salt consumption rate,and non-iodized salt rate were 99.73%,93.54%,93.29%, and 0.27%,respectively.The average consumption level of iodized salt in each monitoring area was between 22.80-31.60 mg/kg,and the overall average was 26.00 mg/kg.A total of 2608 urinary iodine samples were monitored in pregnant women, and the median urinary iodine level was 171.90μg/L.The urinary iodine level of pregnant women in early pregnancy was higher than that in the second trimester and third trimester.A total of 23830 people were screened for thyroid dysfunction in 22 districts and counties,and thyroid hormones of 198 people were elevated,with a detection rate of 0.83%.Conclusion The eligible iodized salt consumption rate of pregnant women and the median urinary iodine all met the national standard for the elimination of iodine deficiency disorders,and Chongqing continued to eliminate iodine deficiency disorders.However, in some areas,non-iodized salt,unqualified iodized salt and iodine deficiency in pregnant women still existed,and there was a risk of iodine deficiency.
