【摘要】 本文采用概率抽样法(PPS法)抽取哈尔滨市市区学龄儿童1200名,进行B超法甲状腺体积测量、尿碘测定及智力测验三项指标的调查,以期评价其碘营养状况。结果表明,全市儿童B超法甲状腺肿大率为8.50％,尿碘中位数为95.39μg/L,平均智商(IQ)为101.51±14.42。按国际推荐指标及国家制定的碘缺乏病消除标准进行评价,哈尔滨市学龄儿童存在轻度碘缺乏;通过这一目标人群的调查结果,可以推测哈尔滨市人口摄碘不足,建议立即采取以碘盐为主的综合补碘措施。更多还原

【Abstract】 In order to assess the iodine - nutritional status of school - aged children in Harbin city, three indicators including thyroid volume by ultrasound, urinary iodine and intelligent quotient (IQ) were examined in 1200 pupils selected randomly by PPS method. The results showed that the total goitre rate by ultrasound was 8. 50%,median value of urinary iodine was 95. 39μg/L and mean IQ level was 101. 51 + 14. 42 respectively in whole city’s level. Based on the prevalent indicators of IDD recommended by WHO/UNICEF/ICCIDD and the national criteria for elimination of IDD,mild iodine deficiency exists in school-aged children of Harbin city,which indicates that iodine intake is not adequate in harbin citizen,suggesting that a comprehensive control program mainly consisting of iodized salt should be implemented immediately in Harbin.更多还原
