We estimate the prevalence of erectile dysfunction in Finland and its effect on frequency of sexual intercourse.
A population based study of 3,143, 50, 60 and 70-year-old men in Tampere and 11 municipalities in the same county was conducted by mailed questionnaire. The definition of erectile dysfunction was based on difficulties in achieving an erection before sexual intercourse and maintaining it. Erectile dysfunction was classified into 4 groups as none, minimal, moderate and complete. To estimate the effect of erectile dysfunction on the frequency of sexual intercourse the men were divided into those who had intercourse at least an average of once weekly and those who did not.
A total of 2,198 questionnaires (70%) were returned and 1, 983 men (63%) were included in the study. Of these men 26% had no, 48% minimal, 14% and 12% complete erectile dysfunction, which increased with age (compared with 50-year-old men, the odds ratios for complete erectile dysfunction were 4.5 (95% confidence interval [CI] 2.6-7.5) for 60 and 21 (95% CI 12.5 to 34.7) to 70-year-old men. The effect of erectile dysfunction on the frequency of sexual intercourse could not be accounted for by age or marital status. The adjusted effect was strong among men with moderate (odds ratio 3.5, 95% CI 2.2-5.1) and complete (173, 68-443) erectile dysfunction but minimal erectile dysfunction had no impact (odds ratio 0.9, 95% CI 0. 6-1.3) on the frequency of intercourse.
Erectile difficulties are common and complete erectile dysfunction increases with age. Erectile dysfunction regulates the sex life of men with moderate or complete dysfunction but this association cannot be accounted for by age or marital status. Although mild erectile dysfunction did not completely regulate sex life, its significance is the risk of progression to a more severe sexual life disturbing dysfunction.
我们评估芬兰勃起功能障碍的患病率及其对性交频率的影响。
通过邮寄问卷对坦佩雷及该县11个市镇的3143名50、60和70岁男性进行了一项基于人群的研究。勃起功能障碍的定义基于性交前勃起及维持勃起的困难程度。勃起功能障碍分为无、轻度、中度和重度4组。为评估勃起功能障碍对性交频率的影响，将男性分为平均每周至少性交一次和不性交的两组。
共收回2198份问卷（70%），1983名男性（63%）纳入研究。这些男性中，26%无勃起功能障碍，48%轻度，14%中度，12%重度，患病率随年龄增加（与50岁男性相比，60岁男性重度勃起功能障碍的比值比为4.5（95%置信区间[CI]2.6 - 7.5），70岁男性为21（95%CI 12.5至34.7））。勃起功能障碍对性交频率的影响不能用年龄或婚姻状况来解释。在中度（比值比3.5，95%CI 2.2 - 5.1）和重度（173，68 - 443）勃起功能障碍的男性中，调整后的影响较强，但轻度勃起功能障碍对性交频率无影响（比值比0.9，95%CI 0.6 - 1.3）。
勃起困难很常见，重度勃起功能障碍随年龄增加。勃起功能障碍影响中度或重度功能障碍男性的性生活，但这种关联不能用年龄或婚姻状况来解释。虽然轻度勃起功能障碍并未完全影响性生活，但其意义在于有发展为更严重影响性生活的功能障碍的风险。
