The aim of the present study was to evaluate the relationship of drinking water fluoride levels with children's intelligence quotient (IQ).
Water was collected from initially identified endemic fluoride regions according to the geological research of Government of India. Fluoride concentration of the water was assessed by utilizing fluoride ion selective electrode, Orion 9609BN, and categorized on the basis of fluoride concentration into low, medium, and high-fluoride regions, i.e., Virajpet (low fluoride level < 1.2 ppm), Banavara (Medium fluoride level 1.2-2 ppm), and Mastihalli (High fluoride levels > 3 ppm). Government school from all three villages were selected randomly and IQ levels were assessed by using Raven's Standard Progressive Matrices. This test was conducted on each child in the study sample.
A significant inverse relationship was found between the fluoride concentration in drinking water and IQ ( value = -0.204; < 0.000). It was observed that IQ level was negatively correlated with fluoride concentration in drinking water.
It is concluded that IQ level was negatively correlated with fluoride level in drinking water. Factors that might affect children's IQ need to be considered, and it is necessary to devise solutions for preventing the harmful effects of excessive intake of fluoride ion to the body.
本研究旨在评估饮用水氟含量与儿童智商（IQ）之间的关系。
根据印度政府的地质研究，从最初确定的地方性氟病区采集水样。利用氟离子选择性电极（奥立龙9609BN）评估水中氟化物浓度，并根据氟化物浓度将其分为低氟区、中氟区和高氟区，即维拉杰佩特（低氟水平<1.2 ppm）、巴纳瓦拉（中氟水平1.2 - 2 ppm）和马斯蒂哈利（高氟水平>3 ppm）。从这三个村庄的政府学校中随机选取学校，并使用瑞文标准渐进矩阵测验评估智商水平。对研究样本中的每个儿童进行该测试。
发现饮用水中的氟化物浓度与智商之间存在显著的负相关关系（值 = -0.204；<0.000）。观察到智商水平与饮用水中的氟化物浓度呈负相关。
得出智商水平与饮用水中的氟含量呈负相关的结论。需要考虑可能影响儿童智商的因素，并且有必要制定解决方案以防止过量摄入氟离子对身体产生有害影响。
