北京市城区与郊区中老年男性性功能的现状调查

Sexual function of middle-aged and older males in Beijing: Urban versus suburban area

目的:调查并比较北京市城区与郊区中老年男性勃起功能障碍(ED)、性欲低下和射精障碍的患病情况。方法:采用分层多阶段整群不等比例随机抽样方法选择北京市15个社区1 656例年龄≥50岁男性作为调查对象,分别记录国际勃起功能问卷(IIEF-5)评分及男性性功能问卷(O'Leary 1995),应用SPSS 17.0对结果进行统计学分析。结果:符合标准的调查对象共1 644例,城区1 244例,郊区400例。IIEF-5评分、性欲评分和射精评分的中值,城区为5、2和4,郊区为13、2和5,城区与郊区间相比的差异有统计学意义(P<0.01)。城区与郊区间IIEF-5评分的差异与年龄、糖尿病和心脑血管疾病的患病情况、是否饮酒和服用5α还原酶抑制剂相关(P<0.01)。结论:郊区中老年男性性功能优于城区。郊区中老年男性的总体年龄小、心脑血管疾病和糖尿病的患病率低,以及较少应用5α还原酶抑制剂和适量的饮酒可能是造成勃起功能优于城区的原因。

Objective： To investigate and compare the prevalence of erectile dysfunction, hyposexuality and ejaculation disorder among middle-aged and older males in the urban and suburban areas of Beijing. Methods： Using the random sampling method, we selected 1 656 men aged 〉--50 years from 15 communities in Beijing. We recorded their scores on the International Index of Erectile Function-5 （ IIEF-5 ） and Brief Male Sexual Function Inventory for Urology （ 0Teary 1995 ）, and analyzed the obtained data using SPSS 17.0. Results ： Totally, .1 644 of the subjects were qualified for the study, 1 244 from the urban area and the other 400 from the suburbs. The median scores on IIEF-5, sexual desire and ejaculation were 5, 2 and 4 in the urban males as compared with 13, 2 and 5 in the suburban men, with statistically significant differences between the two groups （P 〈 0.01 ）. The IIEF-5 score was signifi- eantly correlated with age, diabetes, cardiocerebrovascular diseases, drinking and administration of 5ot-reductase inhibitor in both the urban and suburban groups （ P 〈 0.01 ）. Conclusion： The sexual function of the middle-aged and older males is better in the suburbs than in the urban area of Beijing. The main reasons might be the lower incidences of diabetes and cardiocerebrovascular diseases, moderate drinking and less use of 5et-reductase inhibitor among the suburban men.
