2017年合肥市区8～10岁学龄儿童尿碘监测结果的分析

了解合肥市区8～10岁学龄儿童尿碘水平、甲状腺肿患病率及两者的关系,为合肥地区防治碘缺乏病( IDD)及科学补碘提供依据.调查8～10岁学龄儿童120例,男54例,女66例,对其进行甲状腺触诊及甲状腺B超检查,同时采集尿液进行尿碘检测.结果显示 120 份尿样尿碘中位数(MUI)为305. 6 μg/L;不同性别(Z= -0. 154,P=0. 123)和不同年龄组(χ2=0. 532,P=0. 766)MUI差异无统计学意义;与2012年食盐加碘政策调整前相比,MUI及甲状腺肿大率有所降低,但差异均无统计学意义;不同性别、不同尿碘水平频数分布间甲状腺容积大小差异无统计学意义.合肥市区8～10 岁学龄儿童虽然较2012 年食盐加碘政策调整前的MUI有所降低,但仍普遍存在碘摄入过量问题.

Analysis of urinary iodine levels of school-aged children aged 8 to 10 years old in Hefei City, 2017

To investigate the urinary iodine levels and the prevalence of the goiter and their relationship in school-aged children aged 8～10 years old in Hefei city, provide the scientific evidence for prevention and control of io-dine deficiency disorders. A total of 120 school-age children aged 8 to 10 years old, including 54 male and 66 fe-male were selected and received thyroid examination by B ultrasound and palpation method, urine was also collect-ed for urinary iodine testing. The results showed that the urinary iodine median ( MUI) in 120 urine samples was 305. 6 μg /L . There was no statistical difference in MUI between different sex groups(Z= -0. 154,P=0. 123) and age groups(χ2=0. 532,P=0. 766). Compared with data from pre-adjustment of the policy of salt iodization in 2012, the values of MUI and the goiter rate had decreased tendency, but there was no significant difference. There were no significant difference in the volume of thyroid among different values of MUI and sex. Compared with data from pre-adjustment of the policy of salt iodization in 2012, the values of MUI has decreased in some extent in the present study, but the dose of iodine intake is still excessive.
