Relationship of prostate volume, prostatic specific antigen, and body mass index in men over 40 years

This study aims to investigate the relationship between BMI and PSA concentration parameters and prostate volume in men over 40 years old in Ahvaz City. This descriptive-analytical study was conducted on apparently healthy men over 40 years of age. parameters such as age, BMI, prostate volume, and PSA level were checked in all subjects. The relationship between age, BMI, prostate volume, and PSA level in men over 40 years of age was evaluated as prostate cancer diagnosis parameters. Finally, 180 men with the mean age of the subjects was 58.61 ± 10.01 years. A significant relationship was observed between BMI and prostate volume (p=0.019), BMI and PSA level (p=0.001), prostate volume and age of patients (p<0.001), and age and PSA level (r=0.821 and p<0.001). People with higher BMI had higher average prostate volume and PSA level compared to people with lower BMI, increasing age was significantly associated with increasing prostate volume and PSA level. There was no correlation between prostate volume and PSA level (p=0.37). The results of this hospital study show that increasing BMI and increasing age are positively related to PSA concentration and prostate volume, but no correlation was observed between PSA and prostate volume. BMI and age may be the best parameters to estimate PSA concentration and prostate volume.
