【摘要】 目的 了解漯河市水源性高碘地区儿童碘营养水平，为科学调整干预策略提供依据。方法 2018—2023年按照《全国水源性高碘地区监测方案（2018版）》，在漯河市临颍县每年抽取5个行政村，每个行政村抽取40名8～10岁非寄宿学生（年龄均衡，男女各半，人数不足时年龄扩大到6～12岁），采集儿童随机1次尿样和家庭食用盐盐样，检测尿碘、盐碘含量，同时测量儿童甲状腺容积。结果 2018—2023年每年采集高碘地区儿童尿样200份，尿碘中位数分别为198.5、156.2、358.0、556.0、508.2、441.4μg/L。未加碘食盐率分别为0.0%(0/200)、0.0%(0/200)、6.5%(13/200)、13.0%(26/200)、56.0%(112/200)、26.5%(53/200)。2018—2023年共检测8～12岁儿童甲状腺容积1 200份，甲状腺肿大18人，每年甲状腺肿大率（甲肿率）分别为2.0%(4/200)、0.0%(0/200)、2.0%(4/200)、2.5%(5/200)、0.0%(0/200)、2.5%(5/200)。结论 漯河市水源性高碘地区儿童碘营养水平总体处于过量状态。更多还原

【Abstract】 Objective To understand the level of iodine nutrition among the children in high water-iodine areas of Luohe City, so as to provide the evidence for scientific adjustment of intervention strategies. Methods According to the National Monitoring Protocol for High Water-Iodine Areas(2018 Version), five villages were selected in Linying County, Luohe every year, and 40non-boarding students aged 8-10 years old(age balanced; with an equal number of males and females; age range was adjusted to6-12 years if the number of students was not enough.) were selected from every selected village every year during 2018-2023.One random urine sample and salt sample from household salt for every selected child were collected for detecting the urinary iodine and iodine content in salt, and the thyroid volume of every selected child was measured. Results Collection of 200 urine samples from children in high iodine areas per year,2018—2023, the medians of urinary iodine among the children were 198.5, 156.2,358.0, 556.0, 508.2, 441.4 μg/L, respectively. The proportions of non-iodized salt for the six years were 0.0%(0/200), 0.0%(0/200), 6.5%(13/200), 13.0%(26/200), 56.0%(112/200), 26.5%(53/200), respectively. The thyroid volumes of the selected1 200 children aged 8-12 years were measured, and 18 children had thyroid enlargement. The rates of thyroid enlargement for the six years were 2.0%(4/200), 0.0%(0/200), 2.0%(4/200), 2.5%(5/200), 0.0%(0/200), 2.5%(5/200), respectively. Conclusions The iodine level among the children in high water-iodine areas of Luohe City is excessive.更多还原
