The Relationship Between Gait Function and Erectile Dysfunction: Results from a Community-Based Cross-Sectional Study...

Area of Science:

• Gerontology
• Urology
• Public Health

Background:

• Physical activity is linked to reduced erectile dysfunction (ED) risk, but the connection between ED and overall physical function requires further clarification.
• Understanding these associations is crucial for developing preventative strategies and improving men's health outcomes.

Purpose of the Study:

• To investigate the relationship between gait function and ED in a community-dwelling male population.
• To determine if specific gait parameters serve as independent indicators for ED.

Main Methods:

• A cross-sectional study of 324 Japanese men assessed ED using the 5-Item International Index of Erectile Function (IIEF-5).
• Physical function, including gait (10-meter gait speed, 2-step score) and grip strength, was evaluated.
• Multivariate logistic regression analyzed the association between physical function and low IIEF-5 scores (≤16).

Main Results:

• Nearly half (48%) of the participants had low IIEF-5 scores, indicating ED.
• Men with low IIEF-5 scores exhibited significantly poorer grip strength, 2-step score, and 10-meter gait speed.
• The 2-step score (OR=0.08), age, and total testosterone were independently associated with a low IIEF-5 score.

Conclusions:

• The 2-step score, a measure of gait function, was identified as an independent indicator for the presence of ED.
• This suggests that clinicians should consider assessing physical function, particularly gait parameters like the 2-step score, in men presenting with ED.
• Further research into the predictive value of physical function tests for ED is warranted.
