Erectile dysfunction affects more than 150 million men and is strongly associated with cardiovascular disease. A 1992 National Institutes of Health consensus development panel identified erectile dysfunction progression and spontaneous remission as priorities for investigation, but there are few data describing the natural course of the disorder following its initial presentation. This analysis estimates the frequency of erectile dysfunction progression and remission among aging men, and assesses the relation of progression/remission to demographics, socioeconomic factors, comorbidities and modifiable lifestyle characteristics.
Data from the Massachusetts Male Aging Study, a longitudinal study of men (401) 40 to 70 years old, were analyzed to assess erectile dysfunction severity following initial presentation of symptoms. Logistic regression was used to estimate the odds of erectile dysfunction progression/remission as a function of covariates.
A total of 141 subjects (35%) exhibited erectile dysfunction remission (95% CI: 30%, 40%). Of 323 subjects with minimal or moderate baseline erectile dysfunction 107 (33%) exhibited erectile dysfunction progression (95% CI: 28%, 38%). The 78 subjects with complete erectile dysfunction were considered ineligible for progression and 45 (58%) of these exhibited complete erectile dysfunction at followup. Age and body mass index were associated with progression and remission, while smoking and self-assessed health status were associated with progression only.
Natural remission and progression occur in a substantial number of men with erectile dysfunction. The association of body mass index with remission and progression, and the association of smoking and health status with progression, offer potential avenues for facilitating remission and delaying progression using nonpharmacological intervention. The benefits of such interventions for overall men's health may be far-reaching.
勃起功能障碍影响着超过1.5亿男性,且与心血管疾病密切相关。1992年美国国立卫生研究院共识发展小组将勃起功能障碍的进展和自发缓解确定为优先研究事项,但关于该疾病首次出现后的自然病程的数据却很少。本分析估计了老年男性勃起功能障碍进展和缓解的频率,并评估了进展/缓解与人口统计学、社会经济因素、合并症和可改变的生活方式特征之间的关系。
对马萨诸塞州男性衰老研究的数据进行分析,该研究是一项对401名40至70岁男性的纵向研究,以评估症状首次出现后勃起功能障碍的严重程度。采用逻辑回归来估计勃起功能障碍进展/缓解的几率作为协变量的函数。
共有141名受试者(35%)出现勃起功能障碍缓解(95%置信区间:30%,40%)。在323名基线勃起功能障碍程度较轻或中等的受试者中,107名(33%)出现勃起功能障碍进展(95%置信区间:28%,38%)。78名完全勃起功能障碍的受试者被认为不符合进展条件,其中45名(58%)在随访时仍表现为完全勃起功能障碍。年龄和体重指数与进展和缓解相关,而吸烟和自我评估的健康状况仅与进展相关。
相当数量的勃起功能障碍男性会出现自然缓解和进展。体重指数与缓解和进展的关联,以及吸烟和健康状况与进展的关联,为通过非药物干预促进缓解和延缓进展提供了潜在途径。此类干预对男性整体健康的益处可能是深远的。
