The data were analyzed by Descriptive analysis,χ2test、Fisher’s Exact Test、 Rank sum test and miti-factors logistic regression analysis by SPSS16.0.Results:(1) Total number of thesurvey was394cases in effect. After data cleaning-up there were380cases up to standard.185cases in parents group and195cases.in control group. In parents group, the youngest was18years old and the eldest was49years old. the mean age (33.312.96) years old; in control group, the youngest was21years old and the eldest was51years old, mean age (30.192.65) years old.

With Backward:LR αλ=0.05, α出=0.10, and muti-factors logistic regression analysis, we finally had chose out7main risk factors (P<0.05).These risk factors were spicy food, drinking alcohol, fixed position, holding back urine, wearing skinny pants, frequency of masturbation in a week, taking Yang-strengthening drug.Conclusion:(1) By single factor analysis, it showed that the following factos were connected to chronic prostatitis:degree of education,marrige, occupation, spicy food, eating fruits, drinking alcohol, riding bicycle, sitting for long time, frequency of sports in a week, stay up all night, holding back urine, constipation, wearing skinny pants, use condoms, frequency of masturbation in a week, history of unclean coitus, taking Yang-strengthening drug, inhibitory impulse, coitus interruptus, introverted character, etc.(2) By muti-factor analysis, it showed that the risk factors of Chronic prostatitis include:spicy food, drinking, f fixed position, regularly holding back urine, wearing skinny pants, high frequency of masturbation in a week, taking Yang-strengthening drug.
