The objectives of this study were to (model in the classification level of symptoms and) to develop predictive models of risk acute fluoride poisoning on bone in the elderly.Using logistic regression model The data used were from the data of the development of international cooperation of dental public health, the general information, health information. Consumption of water.Joint and muscle of the elderly in tambon Mae Hoi ngoen, DOI saket district and tambon Korn metropolitan of 50 people. And the following sequence 30
.Analysis by logistic regression methods multi group (Multinomail logistic regression) indicated that the level of fluoride during urination. Affect the classification level of symptoms of the condition fluoride poisoning on bone in the elderly, at the level of the significant 0.05 and logit 2 equation equation is logit_1 = 2.025 - 2.708 (fluoride, rather than as 1 but less than 2) - 3.114 (quantity fluoride. More than equal to 2), logit_2 = 1.609 - 2.526 (fluoride, rather than as 1 but less than 2) - 2.862 (fluoride, rather than as 2) and logit_3 = 0 (due to logit_3 here is the level of symptoms and phase 2 3 is reference. Category is 0).24.8 (〖 R_CS 〗
2 = 0.248) and predict the correct percentage 57.5 from the equation logit initially found that the equation can predict the symptoms only 2 level. No symptoms of fluoride poisoning and a fluoride poisoning in the 2 or 3 only.1 that show no obvious symptoms result in difficult to diagnose. It has been analyzed with logistic regression methods bis (Binary logistic regression) model discriminating people with symptoms of fluoride poisoning on bones and no symptoms.Fluoride content in urine as well as discriminant analysis level of symptoms, significant 0.05 and model prediction is log (odds) = - 0.222 1.667 (fluoride content in urine). The model can explain the variation of acute fluoride poisoning in the elderly have 12.3 (〖 R_CS 〗
2 = 0.123) and equation correctly 71 percent.3 when do determine the suitability of the model by using the Hosmer and Lemeshow showed that the model is appropriate (x
2 =, = 1.233 p-value 0.873). Significant 0.05
