There are no reported studies assessing the relation between diet and erectile dysfunction (ED) in men with diabetes.
In the present study, we explored the relation between consumption of a Mediterranean-type diet and ED in a population of type 2 diabetic men.
Patients with type 2 diabetes were enrolled if they had a diagnosis of type 2 diabetes for at least six months but less than 10 years, age 35-70 years, body mass index (BMI) of 24 or higher, HbA1c of 6.5% or higher, treatment with diet or oral drugs. All diabetic patients were invited to complete a food-frequency questionnaire and self-report measures of sexual function. A total of 555 (90.8%) of the 611 diabetic men completed both questionnaires and were analyzed in the present study.
Adherence to a Mediterranean diet was assessed by a 9-point scale that incorporated the salient characteristics of this diet (range of scores, 0-9, with higher scores indicating greater adherence). ED was assessed with the International Index of Erectile Function-5.
Diabetic men with the highest scores (6-9) had lower BMI, waist circumference, and waist-to-hip ratio, a lower prevalence of obesity and metabolic syndrome, a higher level of physical activity, and better glucose and lipid profiles than the diabetic men who scored <3 points on the scale. The proportion of sexually active men showed a significant increase across tertiles of adherence to Mediterranean diet (from 65.1% to 74.4%, P = 0.01). Moreover, men with the highest score of adherence were more likely to have a lower prevalence of global ED (51.9% vs. 62%, P = 0.01) and severe ED (16.5% vs. 26.4%, P = 0.01) as compared with low adherers.
In men with type 2 diabetes, greater adherence to Mediterranean diet is associated with a lower prevalence of ED.
目前尚无研究评估糖尿病男性的饮食与勃起功能障碍（ED）之间的关系。
在本研究中，我们探讨了 2 型糖尿病男性人群中地中海饮食的摄入与 ED 之间的关系。
如果患者患有 2 型糖尿病至少 6 个月但不超过 10 年、年龄在 35-70 岁之间、体重指数（BMI）≥24、糖化血红蛋白（HbA1c）≥6.5%、接受饮食或口服药物治疗，则将其纳入研究。所有糖尿病患者均被邀请填写食物频率问卷和性功能自评量表。共有 611 名糖尿病男性中的 555 名（90.8%）完成了两份问卷，并在本研究中进行了分析。
采用 9 分制评估地中海饮食的依从性，该评分纳入了这种饮食的显著特征（评分范围 0-9，得分越高表示依从性越高）。ED 采用国际勃起功能指数-5 进行评估。
在评分最高（6-9 分）的糖尿病男性中，BMI、腰围和腰臀比较低，肥胖和代谢综合征的患病率较低，身体活动水平较高，血糖和血脂水平较好。随着对地中海饮食依从性的三分位分层，活跃性生活的男性比例显著增加（从不依从者的 65.1%增加到依从者的 74.4%，P=0.01）。此外，与低依从者相比，依从性评分最高的男性患全球 ED（51.9%比 62%，P=0.01）和重度 ED（16.5%比 26.4%，P=0.01）的患病率较低。
在 2 型糖尿病男性中，较高的地中海饮食依从性与 ED 的较低患病率相关。
