The purpose of this study was to determine whether barriers to exercise differ among racial/ethnic groups at the same stage of exercise adoption and adjacent stages within racial/ethnic groups. Questions about stage of exercise adoption and perceived barriers to exercise were administered to a cross sectional sample of 745 African American, 660 Hispanic, 738 Native American/Native Alaskan, and 769 Caucasian U.S. women aged 40 years and older. Correlations between rankings of barriers among racial/ethnic groups within the same stage ranged from .43 to .89. For each racial/ethnic group, significant differences existed between adjacent stages in the percentage of women reporting barriers to interfere with exercise (p < .10). Barriers were not similar enough among racial/ethnic groups to recommend that the same barriers be addressed for all races/ethnicities.
