BACKGROUND The benefit of regular exercise in improving cancer outcomes is well established. The American Cancer Society (ACS) released a recommendation that cancer survivors should engage in at least 150 minutes of moderate to vigorous physical activity (PA) per week; however, few report meeting this recommendation. This study examined the patterns and correlates of meeting ACS PA recommendations in the Detroit Research on Cancer Survivors (ROCS) cohort of African American cancer survivors. METHODS Detroit ROCS participants completed baseline and yearly follow-up surveys to update their health and health behaviors, including PA. This study examined participation in PA by select characteristics and reported health-related quality of life (HRQOL) as measured with the Functional Assessment of Cancer Therapy and Patient-Reported Outcomes Measurement Information System instruments. RESULTS Among the first 1500 ROCS participants, 60% reported participating in regular PA, with 24% reporting ≥150 min/wk. Although there were no differences by sex, prostate cancer survivors were the most likely to report participating in regular PA, whereas lung cancer survivors were the least likely (P = .022). Survivors who reported participating in regular PA reported higher HRQOL (P < .001) and lower depression (P = .040). CONCLUSIONS Just 24% of African American cancer survivors reported meeting the ACS guidelines for PA at the baseline, but it was encouraging to see increases in activity over time. Because of the established benefits of regular exercise observed in this study and others, identifying and reducing barriers to regular PA among African American cancer survivors are critical for improving outcomes and minimizing disparities.

非裔美国癌症幸存者的体力活动和生活质量：底特律癌症幸存者研究。


背景技术 定期锻炼对于改善癌症结果的益处是众所周知的。美国癌症协会（ACS）发布建议，癌症幸存者每周应进行至少150分钟的中度至剧烈体力活动（PA）；然而，很少有人报告满足了这一建议。本研究考察了底特律癌症幸存者研究 (ROCS) 非裔美国癌症幸存者队列中满足 ACS PA 建议的模式和相关性。方法 底特律 ROCS 参与者完成了基线调查和年度跟踪调查，以更新他们的健康和健康行为，包括 PA。本研究通过选定的特征检查了 PA 的参与情况，并报告了通过癌症治疗功能评估和患者报告结果测量信息系统仪器测量的健康相关生活质量 (HRQOL)。结果 在前 1500 名 ROCS 参与者中，60% 的人报告参加了常规 PA，其中 24% 的人报告每周≥150 分钟。尽管性别没有差异，但前列腺癌幸存者最有可能参加定期 PA，而肺癌幸存者则最不可能 (P = .022)。报告参加定期 PA 的幸存者报告了较高的 HRQOL (P < .001) 和较低的抑郁症 (P = .040)。结论 只有 24% 的非裔美国癌症幸存者报告在基线时符合 ACS 的 PA 指南，但令人鼓舞的是随着时间的推移，活动量有所增加。由于本研究和其他研究中观察到定期锻炼的既定益处，确定并减少非裔美国癌症幸存者定期运动的障碍对于改善结果和最小化差异至关重要。
