ABSTRACT

Background: Benign prostatic hyperplasia is a disease that is clinically characterized by a series of lower urinary tract signs and symptoms (LUTS) due to growth of the prostate. Obesity is excessive accumulation of body fat; general adipose tissue hypertrophy.
Objective: To determine whether or not there is a relationship between body mass index, abdominal perimeter and prostate gland volume obtained by transrectal ultrasound.
Methods: A cross-sectional analytical study was carried out on 123 patients from June to December 2008. Medical history was taken, anthropometric measurements were made and transrectal ultrasound was done. Patients were divided into 3 groups according to body mass index (BMI): normal ‹ 24.9 kg/m2; overweight: 25.0 to 29.9 kg/m2; and obese: › 30.0 kg/m2. They were divided into 2 groups according to abdominal perimeter (AP): normal: ‹ de 90 cm and obese: › 90 cm. Statistical analysis was done with Windows SPSS 15.0 program. Pearson correlation coefficient was used for simple 2-variable correlation.
Discussion: The present study used transrectal ultrasound to more precisely determine prostate volume, as is shown in the literature. However, when variables were analyzed no relation was observed between BMI and prostate volume. A positive linear relation was established between abdominal circumference and prostate volume with correlation between both variables, but this relation was not statistically significant due to sample size and age stratification. There was also no relation seen between prostate volume and patient weight or height.
Conclusion: Even though there was a correlation between study values it was not statistically significant. Further studies with larger patient sample sizes are suggested so that statistically significant relations can be established.
