OBJECTIVE: The aim of this study was to evaluate whether seasonal changes aggravate the symptoms of @entity5116 ( @entity5116 ), by serial administration of the National Institutes of Health @entity1069 Symptom Index (NIH-CPSI) questionnaire for an extended period. MATERIAL AND METHODS: Seventy-seven @entity1 with @entity5116 were serially evaluated with the Korean version of the NIH-CPSI questionnaire every 2-3 months from October 2008 to October 2012. The mean duration of follow-up was 27.11    10.00 months and the mean number of visits per @entity1 was 14.68    5.33 times during the study. RESULTS: The number of @entity1 complaining of @entity158 during the study was 31 in spring and autumn, nine in summer and 18 in winter. However, there were no significant differences in the mean NIH-CPSI scores across the seasons. In spring, summer and autumn, only urination symptoms correlated with quality of life (QoL) (r(2) = 0.277, p < 0.001). In winter, both @entity158 items and urination symptoms correlated with QoL ( @entity158 : r(2) = 0.522, p < 0.001; urination symptoms: r(2) = 0.250, p < 0.001). CONCLUSION: Although fewer severe @entity158 attacks occurred in summer, the mean NIH-CPSI scores did not differ across seasons. The @entity158 from @entity5116 had a greater impact on QoL during winter than it did in the other seasons. In addition, @entity158 was a more significant determinant of QoL than urination symptoms during winter.
