Obesity-Related Anthropometric Indicators and Erectile Dysfunction: A Systematic Review

Area of Science:

• Urology
• Endocrinology
• Metabolic Syndrome

Background:

• Erectile dysfunction (ED) is a common condition with multifactorial causes.
• The role of obesity in ED is debated due to inconsistent findings related to body mass index (BMI).
• Ectopic adipose tissue deposition may contribute to ED, a phenomenon not fully captured by traditional BMI or waist circumference measurements.

Purpose of the Study:

• To review the association between eight obesity-related anthropometric indexes and erectile dysfunction.
• To evaluate the utility of various anthropometric measures beyond BMI and waist circumference in assessing ED risk.
• To highlight the potential of combined anthropometric indicators for improved ED risk prediction.

Main Methods:

• Systematic literature review.
• Analysis of studies examining the relationship between anthropometric indexes and erectile dysfunction.
• Comparison of the efficacy of different anthropometric measures in evaluating adipose tissue distribution.

Main Results:

• Body mass index (BMI) and waist circumference have limitations in assessing ectopic fat, potentially explaining the obesity paradox in ED.
• Six alternative anthropometric indexes (waist-to-height ratio, body shape index, conicity index, abdominal volume index, body roundness index, weight-adjusted waist index) better capture adipose tissue complexity and distribution.
• These alternative indexes may offer improved accuracy in predicting ED risk compared to BMI alone.

Conclusions:

• Traditional measures like BMI and waist circumference may be insufficient for evaluating obesity's impact on erectile function.
• Advanced anthropometric indexes offer a more comprehensive assessment of body composition and ectopic fat deposition relevant to ED.
• Further clinical research, particularly randomized controlled trials, is needed to validate the effectiveness of these indexes in managing ED.
