摘要
A study was conducted to evaluate the effect of high and low fluoride (F) in the drinking water on the Intelligence Quotient (IQ) of young schoolchildren in two otherwise similar high-altitude communities in a mountainous region of Kerman Province, Iran. The study sample consisted of 120 boys and girls age 7-9: 60 in the city of Koohbanan (pop. 12,253; elev. 2200 m) with 2.38 ppm F in the water and 60 in the city of Baft (pop. 14,628; elev. 2300 m) with 0.41 ppm F in the water. Using a Persian version of Raven's Progressive Matrices Intelligence Test, the mean IQ scores of the children in low F Baft was 97.80 +/- 115.95, and in high F Koohbanan it was significantly lower at 91.37 +/- 15.63 (p = 0.028).
