摘要
目的:探讨饮用水中氟和碘的水平对儿童智力发育的影响及其交互作用,以及环境和受教育水平等因素与儿童智力发育的关系。方法:对病区、非病区(对照组)采用随机抽取8～14岁儿童进行氟斑牙、甲状腺肿大患病率及IQ水平测验。结果:在病区,氟、碘两种因素同时存在时,其氟斑牙、甲状腺肿大患病率高于单一因素。儿童IQ均值;单纯高氟、高氟高碘病区与对照组无显著性差异,P>0.05,但有下降趋势,单纯高氟病区与高氟高碘病区间无显著性差异,P>0.05;高氟低碘、低氟低碘病区与对照组IQ均值有极显著性差异,P<0.01;高氟与低碘对IQ水平有极显著的交互作用,P<0.01,高氟病区儿童IQ显著落后对照组;高氟病区儿童IQ水平与父母教育水平及是否经过学前教育均有极显著性差异,P<0.01。结论:高氟高碘两种因素同时存在一个地区对人体的危害大于单一因素,氟的作用小于碘;文化环境因素对儿童智商有直接影响。
Subject: to study effects of fluorine and iodine in drinking water on children' s intelligence development and its interaction, and the relation between children's intelligence development and the environmental and education factors. Methods: Randomly selected 8 - 14year old children in the endemic area and control areas as the investigate subjects, and inspected the prevalence of fluorosis and struma, IQ levels were also measured. Results: in endemic areas, if fluorine and iodine concentration were both high in drinking water, the diseases prevalence was higher, and it was higher than the areas of only fluorine or iodine concentration was high. The average IQ level was not significant lower. There was not significant difference between the areas where only flurine concentration was high and the fluorine and iodine were both high ( P > 0.05) ; IQ level was significantly related with lower concentration ofiodine in drinking water ( P < 0.01) ; and there were interaction between fluorine and iodine toIQ ( P < 0.01). the children living in high fluorine areas, the IQ level were significantly related with their parents education level ( P < 0.01). conclusion: it is a hazardous factor to health if fluorine and iodine levels are both higher in drinking water, and there were interaction effect between fluorine and iodine, the effect of fluorine to health was less than iodine; education and environmental factors can affected the development of intelligence.
