Abstract：Objective To analyze the risk factors of bladder tumor in Northwest China and establish the risk prediction model.Methods A total of 197 patients with bladder tumor in Northwest China from July 2021 to September 2022 were selected as the case group from Xijing Hospital and Tangdu Hospital of Air Force Medical University.In addition,171 non-tumor volunteers admitted to the same hospital at the same period were selected as the control group.Clinical data were collected by questionnaire and medical record system,including gender,age,body mass index,ethnicity,previous history,medication history,mood,smoking,alcohol consumption,water intake,exposure to harmful substances,self-protection awareness,etc.The t test,nonparametric test or chi-square test were used to screen variables with significant differences between the case group and the control group,the differential variables were assigned and logistic regression analysis was performed to clarify the risk factors of bladder tumor in Northwest China,and then the risk factors were weighted to establish a risk prediction model.Finally,the reliability of the prediction model was evaluated by ROC curve.Results Low education(below bachelor level),impatient/irritable mood,long smoking age(≥10 years),long-term use of hair dye(≥ 11 years),weak self-protection awareness,history of urinary system,water intake ≤ 1 200 mL/d and physical exercise ≤ 1 time/week were all risk factors of bladder tumor in Northwest China(P＜0.05).The risk prediction model of bladder tumor in Northwest China based on the above 8 risk factors had a high prediction accuracy(AUC=0.906).Conclusion Maintaining good living habits,controlling negative emotions,strengthening physical exercise,reducing exposure to hair dye,enhancing self-protection awareness,and actively preventing urinary diseases are effective means to prevent bladder tumors.The risk prediction model of bladder tumor established in this study has high accuracy,which is expected to be used for bladder tumor screening in Northwest China.
