To determine if lower urinary tract symptoms (LUTS) involve seasonal variation and how this affects the severity of LUTS.
A total of 3163 men aged 50 to 70 years were mailed a questionnaire on urinary symptoms. The overall response rate was 65.3% (2064 out of 3163 men). The men were asked whether their urinary symptoms showed variation in degree of difficulty according to time of year and if yes, when LUTS were the worst and the mildest. Ten different LUTS were evaluated with four response options for the severity of symptoms. Mean symptom scores and the proportions of symptomatic men were evaluated according to the presence of seasonal changes in different symptoms.
Overall, 17.1% of men reported seasonal variation in severity of LUTS, older men more frequently than younger men. Worse LUTS during winter were reported by 81% of the men reporting seasonal variation, and 93% reported that LUTS were relieved in summer. More seasonal variation was reported by men with comorbidities (stroke, neurological disease) and those with medical treatment for LUTS or operative treatment for benign prostatic hyperplasia. Men with more severe LUTS were more likely to report seasonal changes.
One out of six men reported seasonal changes in LUTS, with winter worsening and summer relieving the symptoms. Men with seasonal variation in LUTS had more severe LUTS in all 10 symptom groups that were investigated.
确定下尿路症状 (LUTS) 是否存在季节性变化，以及这如何影响 LUTS 的严重程度。
共向 3163 名年龄在 50 至 70 岁之间的男性邮寄了一份关于尿症状的问卷。总体回复率为 65.3%（3163 名男性中有 2064 名）。男性被问及他们的尿症状是否根据一年中的时间而在严重程度上有所变化，如果是，LUTS 何时最严重和最轻微。十种不同的 LUTS 用四个症状严重程度的反应选项进行评估。根据不同症状的季节性变化，评估平均症状评分和有症状男性的比例。
总体而言，17.1%的男性报告 LUTS 的严重程度存在季节性变化，年龄较大的男性比年龄较小的男性更频繁。报告有季节性变化的男性中，81%的人在冬季 LUTS 加重，93%的人报告夏季 LUTS 缓解。合并症（中风、神经疾病）的男性以及因 LUTS 接受治疗或因良性前列腺增生接受手术治疗的男性报告更多的季节性变化。LUTS 更严重的男性更有可能报告季节性变化。
六分之一的男性报告 LUTS 存在季节性变化，冬季症状加重，夏季缓解症状。在所有调查的 10 个症状组中，LUTS 存在季节性变化的男性 LUTS 更严重。
