Lack of physical activity is a leading contributor to obesity in the US. The unusually high rates of obesity in African-American (AA) women corroborate with lack of recommended levels of exercise in this population. The purpose of this study was to describe exercise behaviors and intention to change using the stages of change (SOC) model in a sample of AA women. A population-based observational study was conducted with 292 AA women in Florida. Outcome variables were engaging in aerobic, strength-based, and stretching exercise. More than half (61.25 %) did not engage in strength-based exercise, more than a third (37.7 %) did not engage in aerobic exercise, and a little less than half (45.9 %) did not participate in stretching exercise. SOC was the main independent variable. Women in action and maintenance SOC were significantly more likely to engage in aerobic exercise (OR 16.1, 95 % CI 7.09–25.7), strength-based exercise (OR 15.4, 95 % CI 6.58–22.7), and stretching exercise (OR 3.80, 95 % CI 1.91–7.52). The SOC is reflective of actual exercise behavior in AA women. A large number of AA women do not engage in regular recommended levels of exercise. Understanding SOC can be essential to developing culturally appropriate and motivation matched interventions for improving AA women’s exercise habits.
