Summary

Central obesity, not just high BMI, independently increases the risk of prostatic hyperplasia in men without metabolic diseases. This highlights the importance of waist circumference in prostate health.

Area of Science:

  • Urology
  • Metabolic Health
  • Obesity Research

Background:

  • Obesity-related metabolic diseases may impact prostate health.
  • Previous studies suggest a link between obesity and prostatic hyperplasia.
  • The specific role of obesity without comorbidities requires further investigation.

Purpose of the Study:

  • To examine the impact of obesity on prostate volume in men without overt obesity-related metabolic diseases.
  • To identify obesity metrics (BMI, waist circumference) associated with prostate enlargement.
  • To determine if central obesity is an independent risk factor for prostatic hyperplasia.

Main Methods:

  • Recruited 146 men over 40 without diabetes, hypertension, or dyslipidemia.
  • Classified participants into groups based on Body Mass Index (BMI) and waist circumference using Asia-Pacific criteria.

  • Utilized transrectal ultrasonography to measure prostate volume and assessed factors related to prostatic hyperplasia.

    • Main Results:

    • Prostate volume was significantly greater in obese (BMI ≥ 25 kg/m²) and central obesity (> 90 cm waist) groups compared to normal groups.
    • Central obesity was identified as an independent factor affecting prostatic hyperplasia (prostate volume > 20 mL).
    • Men with high BMI and central obesity had a significantly increased risk of prostatic hyperplasia (OR = 4.88, p = 0.008).

    Conclusions:

    • Obesity and central obesity are associated with increased prostate volume, even in the absence of overt metabolic diseases.
    • Central obesity, specifically, is a significant independent risk factor for prostatic hyperplasia.
    • Waist circumference measurement is crucial for assessing prostate hyperplasia risk in obese individuals.
