Association between comorbidity and erectile dysfunction in patients with diabetes

Area of Science:

• Endocrinology
• Urology
• Psychiatry

Background:

• Diabetes mellitus is a prevalent chronic condition associated with numerous complications.
• Erectile dysfunction (ED) and depressive symptoms are common comorbidities in diabetic patients.
• Understanding the interplay between diabetes, ED, depression, and cardiovascular disease (CVD) is crucial for patient management.

Purpose of the Study:

• To determine the prevalence of erectile dysfunction (ED) in patients with diabetes.
• To investigate the relationship between ED and comorbidities such as depression and cardiovascular disease (CVD) in this population.

Main Methods:

• A cross-sectional study involving 312 diabetic patients aged 20+ in Hamadan, Iran.
• Erectile dysfunction assessed using the International Index of Erectile Function (IIEF-5).
• Depression evaluated with the Beck Depression Inventory (BDI-II).
• Logistic regression and stratification used for confounding control.

Main Results:

• The prevalence of moderate to complete ED was 34%; moderate to severe depressive symptoms were present in 30%.
• Increased diabetes duration correlated with higher ED risk (10% per year).
• Depression (OR=10.7) and CVD (OR=2.0) were significant risk factors for ED.
• The combination of depression and CVD yielded a substantially higher ED risk (OR=17.2).
• Lower fruit consumption was associated with increased ED risk (OR=3.2).

Conclusions:

• A strong association exists between depressive symptoms and ED in diabetic patients, particularly pronounced in older men.
• CVD is an independent risk factor for ED, with a notable interaction between depression and CVD in elevating ED risk.
• Dietary factors, such as fruit consumption, may play a role in erectile function.
