摘要
目的 了解湖州市德清县8~10岁儿童和孕妇碘营养状况,为科学调整碘缺乏病预防策略提供依据。方法 采用多阶段分层随机抽样方法,每年在东、西、南、北、中5个片区分别随机抽取1个镇(街道),每个镇(街道)抽取1所小学,每所小学抽取8~10周岁非寄宿学生42人,每个镇(街道)抽取21名孕妇,检测每名学生和孕妇家中食用盐碘含量和尿碘含量。B超法测量并计算2024年儿童甲状腺容积。结果 2022—2024年共监测630名儿童和315名孕妇。检测家中食用盐945份,盐碘中位数为23.91 mg/kg,合格碘盐食用率为91.85%。检测儿童尿样630份,尿碘中位数为204.75μg/L,碘不足93人、碘适宜216人、碘超适宜197人、碘过量124人,分别占14.76%、34.29%、31.27%、19.68%。检测孕妇尿样315份,尿碘中位数为157.73μg/L,碘不足139人、碘适宜125人、碘超适宜43人、碘过量8人,分别占44.13%、39.68%、13.65%、2.54%。2024年测量210名8~10岁儿童甲状腺,甲状腺肿大率为3.33%。结论 德清县重点人群碘营养状况总体适宜。应继续加强食用加碘盐政策宣传,强化科学补碘,预防碘缺乏病的发生。
Objective To understand the iodine nutrition status of children aged 8 to 10 years and pregnant women in Deqing County,Zhejiang Province,and to provide a basis for scientifically adjusting the prevention strategies for iodine deficiency disorders.Methods A multi-stage stratified random sampling method was used to randomly select one town(street)from each of the five areas of east,west,south,north and centre each year.One primary school was selected from each town(street),and 42 non-boarding students aged 8 to 10 years were selected from each primary school.Additionally,21 pregnant women were randomly selected from each town(street).The iodine content in household salt and urine samples of each student and pregnant woman was tested.The thyroid volume of children in 2024 was measured by B-ultrasound and calculated.Results A total of 630 children and 315 pregnant women were monitored from 2022 to 2024.A total of 945 samples of edible salt were tested,and the median salt iodine level was 23.91 mg/kg,and the qualified iodized salt consumption rate was 91.85%.A total of 630 urine samples from children were tested,with a median iodine content of 204.75μg/L.There were 93 cases of iodine deficiency(14.76%),216 cases of adequate iodine(34.29%),197 cases of above adequate iodine(31.27%),and 124 cases of excessive iodine(19.68%).A total of 315 urine samples from pregnant women were tested,with a median iodine content of 157.73μg/L.There were 139 cases of iodine deficiency(44.13%),125 cases of adequate iodine(39.68%),43 cases of above adequate iodine(13.65%),and 8 cases of excessive iodine(2.54%).The goiter rate of 210 children aged 8 to 10 in 2024 was 3.33%.Conclusion The iodine nutrition status of key populations in Deqing County was generally adequate.Publicity on the policy of consuming iodized salt should be continued and strengthened,and scientific iodine supplementation should be enhanced to prevent the occurrence of iodine deficiency disorders.
