To investigate the influence of environmental factors on chronic prostatitis-like symptoms among young men in a community.
Of 28,841 men aged 20 years dwelling in the community, a total of 16,321 men (response rate 56.6%) were included in this study. The National Institutes of Health Chronic Prostatitis Symptom Index was used to identify men with chronic prostatitis-like symptoms. The questionnaire also queried sociodemographic characteristics. The Korean Meteorological Administration provided information on the weather of the community. We determined the risk factors of chronic prostatitis-like symptoms among these environmental factors using univariate and multivariate analyses.
Six percent of the men were identified as having significant prostatitis-like symptoms (perineal and/or ejaculatory pain and a total pain score of 4 or greater). The univariate logistic regression analysis indicated that education level, average duration of sunlight, and average temperature were risk factors for chronic prostatitis-like symptoms. As these variables increased, the scores of chronic prostatitis-like symptoms decreased. In the multivariate model used, the likelihood of chronic prostatitis-like symptoms varied by the final educational level, with middle school and high school graduates having 1.8 and 1.4-fold higher odds, respectively, than men attending college. In the same model, the average duration of sunlight was also an independent risk factor of chronic prostatitis-like symptoms (odds ratio 0.85; 95% confidence interval 0.77 to 0.95; P = 0.003), but the average temperature lost statistical significance.
Our findings suggest that the community-based prevalence of chronic prostatitis-like symptoms may be high in young men. Higher education and a longer time in sunlight were associated with a decreased likelihood of chronic prostatitis-like symptoms.
调查环境因素对某社区年轻男性慢性前列腺炎样症状的影响。
在该社区居住的28841名20岁男性中，共有16321名男性（应答率56.6%）纳入本研究。采用美国国立卫生研究院慢性前列腺炎症状指数来识别有慢性前列腺炎样症状的男性。问卷还询问了社会人口学特征。韩国气象厅提供了该社区的天气信息。我们通过单因素和多因素分析确定了这些环境因素中慢性前列腺炎样症状的危险因素。
6%的男性被确定有明显的前列腺炎样症状（会阴部和/或射精疼痛，总疼痛评分4分或更高）。单因素逻辑回归分析表明，教育水平、平均日照时长和平均温度是慢性前列腺炎样症状的危险因素。随着这些变量增加，慢性前列腺炎样症状评分降低。在所用的多因素模型中，慢性前列腺炎样症状的可能性因最终教育水平而异，初中和高中毕业生患慢性前列腺炎样症状的几率分别比大学学历男性高1.8倍和1.4倍。在同一模型中，平均日照时长也是慢性前列腺炎样症状的独立危险因素（比值比0.85；95%置信区间0.77至0.95；P = 0.003），但平均温度失去统计学意义。
我们的研究结果表明，社区中年轻男性慢性前列腺炎样症状的患病率可能较高。高等教育和较长日照时间与慢性前列腺炎样症状的可能性降低有关。
