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.
缺乏体育活动是美国肥胖问题的主要成因。非裔美国（AA）女性中异常高的肥胖率与该人群缺乏建议的运动水平相符。本研究的目的是使用行为改变阶段（SOC）模型描述AA女性样本中的运动行为及改变意愿。对佛罗里达州的292名AA女性进行了一项基于人群的观察性研究。结果变量包括进行有氧运动、力量训练和伸展运动。超过一半（61.25%）的人未进行力量训练，超过三分之一（37.7%）的人未进行有氧运动，略少于一半（45.9%）的人未参与伸展运动。SOC是主要自变量。处于行动和维持阶段的女性进行有氧运动（比值比16.1，95%置信区间7.09 - 25.7）、力量训练（比值比15.4，95%置信区间6.58 - 22.7）和伸展运动（比值比3.80，95%置信区间1.91 - 7.52）的可能性显著更高。SOC反映了AA女性的实际运动行为。大量AA女性未进行常规建议水平的运动。了解SOC对于制定符合文化背景且能激发动力的干预措施以改善AA女性的运动习惯至关重要。
