摘要
目的 为了解“十三五”期间三明市碘缺乏病防治效果,持续动态观察新标准执行后三明市重点人群碘营养水平,为三明市碘缺乏病防控策略提供科学依据。方法 2016-2020年,按照《福建省碘缺乏病监测方案》要求,在福建省三明市12个监测县中,每个县各随机抽取5个乡镇(街道),每个乡镇(街道)各抽取1所小学40名8~10岁非寄宿学生,开展盐碘、尿碘含量检测和甲状腺B超检查;在每个监测乡镇(街道)中,各抽取孕妇20人,开展盐碘、尿碘含量检测。结果 共检测学生家庭食用盐10 993份,碘盐覆盖率为99.21%(10 907/10 993),非碘盐率为0.78%(86/10 993),非碘盐率呈逐年上升趋势(χ^(2)=8.79,P<0.01)。碘盐合格率为98.02%(10 691/10 907),合格碘盐食用率为97.25%(10 691/10 993),碘盐中位数为24.10 mg/kg,尿碘中位数为219.30μg/L,甲状腺肿大率1.55%(170/10 993);共检测孕妇家庭食用盐5 284份,碘盐覆盖率为99.34%(5 249/5 284),非碘盐率为0.66%(35/5 284),非碘盐率呈逐年上升趋势(P<0.01)。碘盐合格率为98.38%(5 164/5 249),合格碘盐食用率为97.73%(5 164/5 284),碘盐中位数为24.10 mg/kg,尿碘中位数为146.30μg/L;孕早期妇女碘营养水平高于中晚期(P<0.01)。结论 三明市连续5年持续保持碘缺乏病消除状态,孕妇存在碘缺乏风险,应加强对孕妇等重点人群开展宣传教育,维持其碘营养适宜水平。
Objective To understand the effect of prevention and control of iodine deficiency disorders(IDD) in Sanming city during the "13 th 5-Year Plan" period, to continuously and dynamically observe the iodine nutrition level of key populations in Sanming city after the implementation of the new standards, so as to provide a scientific basis for the prevention and control strategies of IDD in Sanming city. Methods In accordance with the requirements of the Iodine Deficiency Disease Monitoring Program of Fujian Province during 2016-2020,5 towns(streets) were randomly selected from each county, and 40 non-boarding students aged 8-10 years from 1 primary school were selected from each town(street) to carry out salt iodine, urine iodine content detection and thyroid B-ultrasound examination.In each monitored township(street),20 pregnant women were selected to carry out salt iodine and urine iodine content detection. Results A total of 10 993 household edible salt samples of students were detected, the iodized salt coverage rate was 99.21%(10 907/10 993),the non-iodized salt rate was 0.78%(86/10 993),and the non-iodized salt rate was increasing year by year(χ^(2)=8.79,P<0.01).The qualified rate of iodized salt was 98.02%(10 691/10 907),and the proportion of households using adequately iodized salt was 97.25%(10 691/10 993).The median iodized salts concentration was 24.10 mg/kg, the median urinary iodine concentration(UIC) was 219.30 μg/L.The total goiter rate was 1.55%(170/10 993).At the 5 284 household table salts samples from pregnant women, the coverage of iodized salt was 99.34%(5 249/5 284),the coverage of non-iodized salt was 0.66%(35/5 284)which was on the rise(P<0.01).The qualified rate of iodized salt was 98.38%(5 164/5 249),and of these, the proportion of households using adequately iodized salt was 97.73%(5 164/5 284).The median iodized salts concentration was 24.10 mg/kg, the median UIC was 146.30 μg/L.The iodine nutrition level in early pregnancy was higher than that in the other period(P<0.01). Conclusion Sanming city has maintained the elimination of iodine deficiency disorders for 5 consecutive years.Pregnant women are at risk of iodine deficiency.Therefore, publicity and education for pregnant women and other key groups should be strengthened to maintain the appropriate level of iodine nutrition.
