We conducted a cross-sectional telephone survey to explore the relationship of birth control conspiracy beliefs and perceived discrimination to contraceptive attitudes and behavior among a sample of African Americans (aged 18-45) in the USA (N = 71). Results indicated that a large percentage of respondents perceived discrimination targeted at African American women and endorsed birth control conspiracy beliefs, and that a significant proportion of female respondents perceived discrimination when getting family planning or contraceptive services. Stronger conspiracy beliefs and greater perceived discrimination were associated with negative attitudes toward contraceptive methods, particularly birth control pills, and with contraceptive behavior and intentions. Our findings suggest that conspiracy beliefs and perceived discrimination may play an important role in African Americans' attitudes toward and use of contraceptive methods.
