通过对合肥市３０所小学１２００名１０岁学龄儿童供碘前的甲状腺肿大率、尿碘、智商ＩＱ的系统调查，结果甲状腺肿大率２１．０８％（触诊法），Ｂ超声检查９．０８％，尿碘中位数７５．４μｇ／Ｌ，平均智商１０７，智力低下的儿童占１．０％。综合这些研究结果，提示合肥市儿童碘营养不足，呈轻度碘缺乏状态。说明碘缺乏不仅存在于农村，城市也可发生，实施全民食盐加碘工作乃当务之急。 Through a systematic survey of thyroid goiter, urinary iodine and IQ of 1200 pre-iodine children in 1,200-year-old school-age children in 30 primary schools in Hefei, the results showed that goiter rate was 21.08% (palpation), B ultrasound examination 9 .08%, urinary iodine median 75.4μg / L, average IQ 107, children with mental retardation 1.0%.
