摘要
[目的]了解全民食盐加碘对碘缺乏病区出生儿童智商的影响。[方法]用联合型瑞文测验测定儿童智商(IQ),调查分析社会-经济-文化因素对智力的影响,测定尿碘水平、盐碘含量和甲状腺肿大情况。[结果]实施全民食盐加碘21年后,儿童甲状腺肿大率由57.4%下降到2.5%,尿碘水平由24.9μg/克肌酐升至209.6μg/L;补碘后出生的儿童IQ均值非常显著地高于补碘前,智力低下的发生率明显低于补碘前出生儿;将社会-经济-文化因素与儿童的智商进行多元逐步回归分析,R2=0.314。[结论]实施全民食盐加碘是促进儿童智力发育的重要因素。
To study the children’s intelligence quotient (IQ) by USI in iodine deficiency regions. The children's IQ was measured by the combined Raven's Test and social-economic-cultural factors were analyzed. The level of urinary iodine and iodine in salt were determined, and the thyroid was examined. USI for 21 years, the goiter rate was decreased from 57.4% to 2.5% and urinary iodine was increased from 24.9 μg/gcr to 209.6 μg/L. The IQ of child born after USI was higher than that born before USI (P<0.001). And the incidence of mental retardation was lower than that born before USI. The multivariate stepwise regression analysis shown that IQ development was related to social-economic-cultural factors (R~ 2=0.314). USI is very important factor to promote the development of children’s IQ in iodine deficient areas.
