摘要
目的探讨高氟对儿童智商的影响。方法2006年5月,在陕西省蒲城县某小学选取饮高氟水(3.15mg/L)儿童42名(高氟组)和改水后饮低氟水儿童37名(对照组),测试其智力水平,以Dean’s法进行儿童氟斑牙诊断,以氟离子选择法测定尿氟含量。结果高氟组平均智商(96.11±12.00)低于对照组(98.41±14.75),未检出智商优秀等级以上儿童,其智商分布与对照组比较,差异无统计学意义(P>0.05)。儿童尿氟值与智商值之间呈现负相关关系,但无统计学意义(P>0.05)。结论高氟对儿童的智商可能造成一定程度的损伤。
Objective To explore the effect of high fluoride exposure on children intelligence. Methods Dental fluorosis of children was examined with Deans index and the fluoride contents in the urine were determined with FSIE. In 2006, the level of children intelligence were determined in 2 groups of children, 42 from the high-fluoride area and 37 from the control area. Results The average level of children intelligence in the high-fluoride group was lower than that of the control group by 2 IQ value, while intelligence distribution in these 2 groups did not show any difference (P>0.05). There was a negative correlation between the urine fluoride concentration and children intelligence(P>0.05). Conclusion High fluoride may cause children intelligence decrease.
