To evaluate the effect of sauna bathing on lower urinary tract symptoms (LUTS) in a Finnish population-based cohort.
A mail survey was sent to a population-based cohort of 50-, 60-, and 70-year-old men in 1994 followed by repeat questionnaires in 1999 and 2004. The evaluation of ten different types of LUTS was based on Danish Prostatic Symptom Score (DAN-PSS-1). The weekly frequency of sauna bathing was assessed in the first questionnaire and divided into three subgroups (0-1, 2, and ≥3). The prevalence, incidence, and remission rate of each LUTS was assessed based on the initial and follow-up assessments. In addition, the mean DAN-PSS-1 symptoms score, medication for LUTS, and operative treatment were determined at each time-point. Chi-square test, a linear-by-linear test, and binary logistic regression analysis were used to assess statistical significance.
The population-based cohort included initially 3,163, men of whom 1,306 (41.3%) responded to all three questionnaire rounds and were included in the analysis. There was no clear association between sauna bathing frequency and prevalence of the nine LUTS, nor with incidence and remission rates. The only exception was feelings of incomplete emptying, with lower prevalence associated with frequent sauna bathing. There were no clear differences in the medications or operations for LUTS by sauna bathing habits.
Based on our results, sauna bathing does not affect LUTS development or natural history in the long-term.
评估在芬兰人群队列中，桑拿浴对下尿路症状（LUTS）的影响。
1994 年，我们向一个基于人群的 50、60 和 70 岁男性队列发送了一份邮件调查，随后在 1999 年和 2004 年进行了重复问卷调查。十种不同类型的 LUTS 的评估基于丹麦前列腺症状评分（DAN-PSS-1）。首次问卷调查中评估了每周桑拿浴的频率，并将其分为三组（0-1、2 和≥3 次）。根据初始和随访评估，评估了每种 LUTS 的患病率、发病率和缓解率。此外，在每个时间点还确定了平均 DAN-PSS-1 症状评分、用于 LUTS 的药物和手术治疗。使用卡方检验、线性线性检验和二项逻辑回归分析评估统计学意义。
基于人群的队列最初包括 3163 名男性，其中 1306 名（41.3%）对所有三轮问卷调查做出了回应并被纳入分析。桑拿浴频率与 9 种 LUTS 的患病率之间没有明显关联，也与发病率和缓解率没有明显关联。唯一的例外是排空不完全的感觉，其患病率与频繁的桑拿浴有关。根据桑拿浴习惯，用于 LUTS 的药物或手术也没有明显差异。
根据我们的结果，桑拿浴不会影响 LUTS 的长期发展或自然史。
