摘要
目的分析2017-2019年驻马店市8~10岁儿童的碘营养状况,为进一步开展儿童碘营养监测工作明确方向。方法以驻马店市所辖的9个县(区)为监测点,每个监测点按照东、西、南、北、中5个方位各抽取一个乡镇(街道),每个乡镇(街道)抽取1所中心小学,每所小学随机抽取40名8~10岁儿童,对其家中食用盐样和日间随意一次即时尿样的碘含量进行检测,并用B超法进行甲状腺容积测量。结果共检测儿童家中盐样5402份,盐碘中位数25.40 mg/kg,碘盐覆盖率98.07%,碘盐合格率93.92%,合格碘盐食用率92.11%;共检测儿童尿样4800份,尿碘中位数213.35μg/L;共检测儿童甲状腺容积1800人,甲状腺肿大率0.83%。结论驻马店市8~10岁儿童的盐碘、尿碘结果和甲状腺肿大率均达到国家消除碘缺乏病的标准,但是尿碘含量超过适宜量,需根据实际情况调整策略。
Objective The iodine nutritional status of children aged 8-10 in Zhumadian city from 2017 to 2019 was analyzed so as to clarify the direction for further monitoring of children’s iodine nutrition.Method Nine counties(districts)in Zhumadian city were selected as the monitoring sites.One township(sub-district)was selected from each monitoring site according to the five directions of East,West,South,North and middle.One central primary school was selected from each selected township(sub-district).40 children aged 8-10 years were randomly selected from each selected primary school.The iodine content of salt samples in their homes and the instant urine samples of these children at random in daytime were tested,and B-ultrasound method was used to measure the thyroid volume.Results From 2017 to 2019,a total of 5402 salt samples and 4800 urine samples of children were tested.The median of salt iodine content was 25.4 mg/kg;the iodized salt coverage rate was 98.07%;the acceptable consumption rate of iodized salt was 92.11%,and the qualified rate of iodized salt was 93.92%.The median of urinary iodine concentration was 213.35 g/L.The thyroid volumes of 1800 children were determined,and the goiter rate was 0.83%.Conclusion The results of salt iodine,urine iodine and rate of goiter in children aged 8-10 years in Zhumadian city all meet the national standard for eliminating iodine deficiency disorders,but the number of children whose urinary iodine levels have exceeded the appropriate level increases year by year.The strategy should be adjusted according to the actual situation.
