摘要
目的了解和掌握2019年北京市房山区重点人群碘营养状态,评估房山区现行碘缺乏病防控措施落实情况。方法2019年在北京市房山区抽取5个乡镇/街道,采用多阶段分层随机抽样方法采集8~10岁儿童家中盐样、尿样,检测碘含量,并对儿童进行甲状腺容积B超检测,同时采集学校食堂盐样;在儿童采样地区采集孕妇尿样、盐样,监测碘含量。随机抽取房山区1家孕检医院的111名孕妇采集尿样,随机抽取房山区2个乡镇各100名育龄妇女采集尿样,进行尿碘检测。非正态分布组间采用非参数检验,多独立样本比较采用Kruskal-Wallis H检验,率的比较采用χ^(2)检验,检验水准α=0.05。结果2019年在北京市房山区碘盐覆盖率为94.43%,合格碘盐食用率为92.46%、合格碘盐覆盖率为94.97%,儿童尿碘中位数为164.1μg/L,孕妇尿碘中位数159.4μg/L,育龄妇女尿碘中位数为166.8μg/L,儿童甲状腺肿大率4.93%。结论北京市房山区达到了碘缺乏病消除的判定标准,孕妇尿碘水平有逐年下降趋势,应引起充分注意,重点人群未出现碘过量,坚持科学补碘措施应持续落实。
Objective To understand the iodine nutrition status of the focus groups so as to evaluate the implementation of the current prevention and control measures for iodine deficiency disorders in Fangshan District,Beijing in 2019.Methods Five towns/streets were selected from Fangshan district.Then,a multi-stage stratified random sampling method was used to collect the salt and urine samples of children aged 8 to 10 years old at home aiming to detect the iodine content.The thyroid volume of the selected children was detected by B-mode ultrasound.Meanwhile,the salt samples of the school canteen were collected,and the urine and salt samples of pregnant women were collected in each town to monitor the iodine content.Urine samples were collected from 111 pregnant women in a pregnancy examination hospital in Fangshan district,and 100 women of childbearing age in two towns in Fangshan district were randomly selected for urine iodine test.Nonparametric test was used for non-normal distribution groups.Kruskal-Wallis H test was used for multi-independent sample comparision.Rates were compared by chi-square test and P<0.05 was considered as statistically sifnificant.Results The coverage rates of iodized salt and qualified iodized salt in the district were 94.43%and 94.47%.The consumption rate of qualified iodized salt was 92.46%.The median of urine iodine in children,pregnant women and childbearing age women was 164.1μg/L,159.4μg/L,and 166.8μg/L,respectively.The goiter rate of children was4.93%.Conclusion This district has reached the eliminating standard of iodine deficiency disorders.However,the urine iodine level of pregnant women has been declining year by year,which should bring to the forefront.The iodine excess was not shown in the focus groups,thus the scientific iodine supplement measure should be continued.
