Patients who reported≥2 voids per night was asked to take the 72-hour voiding diary. Quantitive variabes were expressed as mean±standard deviation, the groups were compared with chi-square test(using SPSS 13.0 software). Logistic analysis was used to evaluated the risk factors, including age, hypertension, diabetes, BPH, stress urinary incontinence.

Among them 631(47.8%)were male, 691(52.2%)were female. Gender was not found to be associated with nocturia. OAB is a risk factor for nocturia(P<0.001).There is a significantly difference between people with nocturia more than twice and the others(P12<0.001,P13=0.002,P14<0.001). Hypertension, diabetes, BPH , snoring are associated with nocturia.
