ABSTRACT
Objective@#To investigate the prevalence of erectile dysfunction (ED) in men with pre-diabetes.@*METHODS@#This study included 500 men with impaired fasting glycaemia (IFG), 500 with impaired glucose tolerance (IGT), and another 500 with normal blood glucose (NBG), all from Lanzhou. We conducted a questionnaire investigation among the subjects using the International Index of Erectile Dysfunction 5 (IIEF-5).@*RESULTS@#The prevalence rates of ED in the IFG, IGT, and NBG groups were 14.8%, 29.2%, and 33.2%, respectively. After controlling for age, nationality, occupation, education, income, obesity, and blood pressure, the incidence rate was markedly higher in the IFG and IGT than in the NBG group (29.2% and 33.2% vs 14.8%, P 0.05).@*CONCLUSIONS@#The prevalence of ED is higher in men with pre-diabetes than in those with normal blood glucose in Lanzhou.
