Abstract Background: Esophageal candidiasis (OC) is a common AIDS-defining opportunistic infection. Antiretroviral therapy (ART) reduces the occurrence of OC and other opportunistic infections among persons living with HIV (PLHIV). We sought to determine and compare the prevalence of OC in the ART and pre-ART era among PLHIV in sub-Saharan Africa (SSA). Methods: We searched PubMed, Embase, Web of Science, and the African Journals Online databases to select studies in English and French reporting the prevalence of HIV-associated OC in SSA from January 1980 to June 2020. Reviews, single-case reports, and case series reporting < 10 patients were excluded. A random-effect cumulative meta-analysis was performed using STATA 16.0, and trend analysis performed using GraphPad Prism 8.0. Results: Thirteen eligible studies from 9 SSA countries including a total of 113,272 patients were qualitatively synthesized, and 9 studies were included in the meta-analysis. Overall pooled prevalence of HIV-associated OC was 12% (95% confidence interval (CI): 8 to 15%, I2 = 98.61%, p
