Background: Higher rates of HIV infection among racial/ethnic minority injecting drug users (IDUs) have been reported in North America, South America, Europe and Asia.

Methods: Standard systematic review/meta-analysis methods are utilized, including searching for published and unpublished reports, standardized screening and coding, and meta-analytic statistical techniques.

Results: As of February 1, 2009, 22,635 abstracts were reviewed; 1730 papers were retrieved for further review and potential coding; 110 studies were eligible for inclusion in the meta-analysis and coded: 1) Ethnic disparities were examined in 78 prevalence studies, with 134 ethnic minority to ethnic majority comparisons. A plurality (45) of comparisons was from the US, followed by China (8), and Canada (6). 2) 108 (81%) comparisons showed higher HIV prevalence among ethnic minority IDUs, two (2%) comparisons found identical HIV prevalence, and 24 (18%) comparisons found lower HIV prevalence among ethnic minority IDUs. The mean weighted OR for HIV prevalence in ethnic minority compared to ethnic majority IDUs was 2.41(95% CI 2.30-2.51). 3) The mean weighted OR for HIV prevalence in US Black:White comparisons was 3.13 (95% CI 2.90-3.38), significantly greater than the mean weighted OR for the other ethnic minority:majority comparisons. 4) There was great heterogeneity among the studies (I squared = 86%).

Conclusion: Higher HIV prevalence among ethnic minority IDUs is very common but not inevitable. The great heterogeneity among the studies suggests multiple causal factors contribute to ethnic disparities in HIV infection. Possible reasons for greater disparity in US Black:White comparisons than other ethnic minority:majority comparisons will be discussed.
