Abstract:
Objective To investigate the prevalence of sexual dysfunction in aged men and associated risk factors in Beijing. Methods A cross-sectional study was performed in communities of Beijing involved 1656 men aged over 50 years.The International Index of Erectile Function-5 (IIEF-5),Brief Male Sexual Function Inventory for Urology ( O'Leary 1995 ) and the International Prostate Symptom Score (IPSS)questionnaires was recorded.The body mass index (BMI),prostate size was measured.The survey was conducted to make sure if the patients had diabetes,high blood pressure,hyperlipidemia,cerebrovascular history,and smoking and drinking situation.Pearson's X2 test and unconditional logistic regression were used to investigate the factors associated with sexual dysfunction. Results 1644 subjects were enrolled.The incidence of ED,reduction of sexual desire and defective ejaculation was 90.45％,60.04％ and 38.81％ respectively,and significantly different according to age ( P ＜ O.05 ). Age was positively correlated with ED (3 =0.12,P＜0.05),reduction of sexual desire (β =0.10,P＜0.05) and defective ejaculation (β =0.10,P ＜ 0.05 ) ; ED was significantly associated with BMI (β =0.07,P ＜ 0.05 ).Hypertension and prostate size were risk factors for reduction of sexual desire and defective ejaculation; There was correlation between drinking and defective ejaculation ( β =- O.31,P ＜ 0.05 ). Conelusions Compared with high prevalence of ED and lower sexual desire,the incidence of defective ejaculation were lower; this may reflect the sexual activities of aged male were more active compared with the less success of really erection.The prevalence of ED,reduction of sexual desire or defective ejaculation increased with age.BMI was the risk factor for ED.Enlarged prostate and hypertension was associated with reduction of sexual desire,and drinking was the risk factor for defective ejaculation.
