Some studies have shown an association between race and BPH severity [3,4], though these associations may be confounded by socioeconomic factors such as income and insurance [5]. In one study, while the age-adjusted relative risk (RR) of BPH necessitating surgery was similar for Black and White patients, Black patients younger than 65 years old needed treatment more often compared with White patients [3]. In a community sample of 2480 men in the United States, moderate to severe LUTS was more common in Black men than White men (41 versus 34 percent) [4], and Black patients had greater total and transitional zone prostate volume [6,7]. In a study of 34,624 men, Asian patients had a lower risk of clinician-diagnosed BPH (RR 0.7, 95% CI 0.2-0.5) compared with Black and White patients with similar risk [8]. Additionally, in the American Male Health Professional Study, Asian American patients were less likely (RR 0.4, 95% CI 0.2-0.8) to undergo surgery for BPH compared with White patients
