Association of fluoride in water for consumption and chronic pain of body parts in residents of San Kamphaeng district, Chiang Mai, Thailand

Objective To assess the dose response of fluoride exposure from water and chronic pain. Methods Using a retrospective cohort design, the study was conducted in two sub-districts of San Kamphaeng district, Poo-kha and On-tai. Five hundred and thirty-four residents aged ≥50years of age were interviewe...

Methods Using a retrospective cohort design, the study was conducted in two sub-districts of San Kamphaeng district, Poo-kha and On-tai. Five hundred and thirty-four residents aged ≥50years of age were interviewed about their sources of drinking water and assessed for chronic pain. Each water source was sampled for fluoride measurement, from which the average daily fluoride dose was estimated. Binary logistic regression with forward stepwise (likelihood ratio) model selection technique was used to examine the association between the average daily fluoride dose and chronic pain. Results We found associations between the average daily fluoride dose and lower back pain [odds ratio (OR)=5.12; 95% confidence interval (CI), 1.59-16.98], and between the high fluoride area vs. the low fluoride area (OR=1.58; 95% CI, 1.10-2.28; relative risk=1.22 with 95% CI, 1.14-1.31) to lower back pain. Other risk factors, such as family history of body pain and a history of injury of the lower body, were also associated with lower back pain. However, there were no relationships between the average daily fluoride dose and leg and knee pains. Conclusion To prevent further lower back pain, we recommend that the water in this area be treated to reduce its fluoride content. © 2012 Blackwell Publishing Ltd. 2018-09-04T06:07:00Z 2018-09-04T06:07:00Z 2012-09-01 Journal 13653156 13602276 2-s2.0-84865555601 10.1111/j.1365-3156.2012.03061.x https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84865555601&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/51721
