Objectives To evaluate the J apanese version of the N octuria Q uality‐of‐ L ife questionnaire for prediction of night‐time voiding and risk of falling. Methods A survey was carried out from O ctober 2008 to J une 2009 in outpatients at 15 general hospitals and 80 general clinics in T ochigi, J apan, using the N octuria Q uality‐of‐ L ife questionnaire, overactive bladder symptom score and self‐administered questionnaires on night‐time symptoms (awakening, number of voids, incontinence and falling). Results The survey was completed by 2494 participants (1154 men, 1208 women; mean age 63.2 ± 15.1 years). Overactive bladder was diagnosed in 625 participants (25.1%) according to the J apanese overactive bladder guideline using overactive bladder symptom score. Awakening during sleep was reported by 80.1% of the participants, and 70.4% awakened to go to the toilet. The mean N octuria Q uality‐of‐ L ife score was 86.8 ± 16.9. The N octuria Q uality‐of‐ L ife score was lower in patients with overactive bladder, benign prostatic hyperplasia, diabetes, hypertension and cardiovascular diseases. The N octuria Q uality‐of‐ L ife score was significantly decreased in patients with night‐time symptoms ( P < 0.001). N octuria Q uality‐of‐ L ife scores and those for subdomains were correlated with overactive bladder symptom score. N octuria Q uality‐of‐ L ife ≤90 had 63.1% sensitivity and 78.6% specificity in indicating night‐time voiding more than twice, and N octuria Q uality‐of‐ L ife questionnaire ≤80 had 70.2% sensitivity and 79.5% specificity in indicating the probability of falling at least once. Logistic analysis showed that 10‐year increase in age and overactive bladder in all participants were significant risk factors for N octuria Q uality‐of‐ L ife ≤90. Conclusions The N octuria Q uality‐of‐ L ife questionnaire represents a useful tool to predict nocturia and risk of falling in J apanese patients.
