Objective: This study investigates the association between ethnic minority status and receiving a screening mammogram within the past 2 years among American women over 50. Method: The findings from 33 studies identified from interdisciplinary research databases (1980 to 2006) were synthesized. Separate pooled analyses compared white non-Hispanics to African Americans (28 outcomes), Hispanics (18 outcomes), and Asian/Pacific Islanders (10 outcomes). Results: Using the random effects model, results showed that African Americans were screened less than white non-Hispanics at a marginal level (OR 0.87, 95% CI 0.75, 1.00). Larger and significant discrepancies were observed for Hispanics (OR 0.65, 95% CI 0.50, 0.85) and Asian/Pacific Islanders (OR 0.63, 95% CI 0.39, 0.99) compared to white non-Hispanics. However, among studies controlling for socioeconomic status, ethnic differences in mammography screening were no longer significant for African Americans (OR 1.05, 95% CI 0.71, 1.76), Hispanics (OR 1.08, 95% CI 0.64, 1.93), or Asian/Pacific Islanders (OR 1.08, 95% CI 0.64, 1.93). Subgroup analyses further showed that geographical region, sampling method, and data collection strategy significantly impacted results. Conclusions: This study found evidence that ethnic minority-screening mammography differences exist but were impacted by socioeconomic status. Implications for interpreting existing knowledge and future research needs are discussed. © 2007 Elsevier Inc. All rights reserved.
