A total of 25 studies fulfilled the inclusion criteria, and a <jats:styled-content style="fixed-case">B</jats:styled-content>ayesian logistic meta‐regression was carried out to examine the association between histological prevalence, age by decade and ethnic group (white, <jats:styled-content style="fixed-case">A</jats:styled-content>frican <jats:styled-content style="fixed-case">A</jats:styled-content>merican and <jats:styled-content style="fixed-case">C</jats:styled-content>hinese/<jats:styled-content style="fixed-case">J</jats:styled-content>apanese).</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Histological cancer was estimated to increase with age from 2% (95% confidence interval 1–3%) between 20–29 years‐of‐age to 69% (95% confidence interval 51–83%) by 90–99 years‐of‐age in the white ethnic group. The <jats:styled-content style="fixed-case">A</jats:styled-content>frican <jats:styled-content style="fixed-case">A</jats:styled-content>merican group was associated with the highest prevalence of cancer, albeit non‐significantly (odds ratio 1.2, 95% confidence interval 0.9–1.5), whereas the <jats:styled-content style="fixed-case">C</jats:styled-content>hinese/<jats:styled-content style="fixed-case">J</jats:styled-content>apanese group was significantly associated with the lowest prevalence relative to the white group (odds ratio 0.6, 95% confidence interval 0.4–0.9).</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>The present study provides an updated and improved analysis of the histological prevalence of prostate cancer. The results confirm ethnicity as a potential predictor of prevalence, but highlight the need for further research in the area. The findings are valuable for understanding the epidemiology and natural history of prostate cancer across ethnicities, and increasing the body of evidence aimed at estimating benefits and risks associated with prostate cancer screening programs.</jats:p></jats:sec>
