The aim was to assess and correlate the influence of the concentration of fluoride in ingested water on the intelligence quotient (IQ) of 12-14-year-old youngsters in Mathura district.
A total of 219 children were selected, 75 from low F area, 75 medium F area, and 69 from high F area. The concentration of fluoride in the routinely ingested water was estimated using "Ion Selective Electrode method"; then, Raven's Test was utilized to estimate the IQ of the study participants. Independent -test, Tukey's , Chi-square an analysis of variance tests were used to associate the mean and proportion IQ scores in high-, medium-, and low-fluoride regions along with inter-group significant differences ( ≤ 0.05).
The comparison of IQ score showed that 35 (46.7%) participants from the high fluoride and 10 (13.3%) participants from the medium-fluoride areas had below average IQ. Further, it was noted that the lowest mean marks were obtained by the children in the high-fluoride region (13.9467) followed by those in medium (18.9467) and uppermost in least noted fluoride area (38.6087). However, gender-based intergroup comparison did not produce a significant relation with fluoride ( ≥ 0.05).
Concentration of Fluoride in the ingested water was significantly associated with the IQ of children. It has also coined the proportional variability in mental output in accordance to the ingested fluoride level. As two sides of a coin, fluoride cannot be utterly blamed for a lower intelligence in a population; it puts forward a fact that intelligence is a multifactorial variable with a strategic role played by genetics and nutrition to develop cognitive and psychosomatic activities in an individual.
评估并关联马图拉地区摄入水中氟化物浓度对12 - 14岁青少年智商（IQ）的影响。
共选取219名儿童，75名来自低氟地区，75名来自中氟地区，69名来自高氟地区。采用“离子选择电极法”估算日常摄入水中的氟化物浓度；然后，利用瑞文测试估算研究参与者的智商。采用独立样本t检验、图基检验、卡方检验和方差分析来关联高氟、中氟和低氟地区的平均智商得分及比例，并分析组间显著差异（P≤0.05）。
智商得分比较显示，高氟地区35名（46.7%）参与者和中氟地区10名（13.3%）参与者的智商低于平均水平。此外，注意到高氟地区儿童的平均分数最低（13.9467），其次是中氟地区（18.9467），氟含量最低地区的分数最高（38.6087）。然而，基于性别的组间比较与氟化物没有显著关系（P≥0.05）。
摄入水中的氟化物浓度与儿童智商显著相关。它还根据摄入的氟化物水平造成了智力产出的比例变化。正如硬币的两面，不能完全将人群中智力较低归咎于氟化物；它揭示了一个事实，即智力是一个多因素变量，基因和营养在个体认知和身心活动发展中起着关键作用。
