Correlation Of Body Mass Index With Prostate Volume In Benign Prostatic Hyperplasia Patients

Abstract

Introduction: Benign prostatic hyperplasia (BPH) is the most common prostatic disease in
men. Multiple factors influence the pathogenesis of BPH, and one of them is obesity. Various
studies about the correlation between obesity and prostate volume show inconsistent results.
Some studies reported that obesity correlates with prostate volume, whereas others didn't find
the correlation between obesity and prostate volume. Therefore, this study aims to find the
correlation between obesity and prostate volume.
Purpose: To find the relationship between body mass index (BMI) and BPH patients'
prostate volume.
Methods: BMI was measured by BMI formula, and prostate volume was measured by
transabdominal ultrasound (TAUS). This study was conducted in RSUD Ibnu Sina
Kabupaten Gresik by looking at medical records in January 2016-September 2017. This study
was an analytical observational study with a cross-sectional approach. This study uses Linear
Regression Test to analyze the correlation of in-between variables. This study's population
was patients with a diagnosis of BPH that undergo hospitalization in RSUD Ibnu Sina (273
medical records). The study sample that corresponding to inclusion and exclusion criteria are
27 medical records.
Result: The average prostate volume in underweight criteria was 44,5 cm3, in normal criteria
is 42,4 cm3. Highest average of prostate volume found in overweight criteria, which was 64,3
cm3. In the obese criteria, the average prostate volume was 32,2 cm3. The average prostate
volume was 46,0 cm3. From the linear regression test, we found the value of p=0,881 and
R2=0,01.
Conclusion: There is no significant correlation between BMI and prostate volume in this
study
