To assess differences in accelerometer-assessed moderate- to vigorous-intensity physical activity (MVPA), light-intensity physical activity, and sedentary time between cancer survivors and adults without cancer.
Accelerometer data collected from 241 breast cancer survivors (ACCEL-Breast study, 2013) and 171 colon cancer survivors (ACCEL-Colon study, 2012-2013) were pooled with data collected from adults without cancer (Australian Diabetes, Obesity and Lifestyle accelerometer substudy, 2011-2012). Linear regression was used to estimate differences in physical activity and sedentary behavior levels between cancer survivors and adults without cancer, adjusted for potential confounding factors.
The mean MVPA was significantly higher among breast cancer survivors than among females who had not had cancer (29 vs 22 min/d; P<.001). Colon cancer survivors had significantly lower levels of light activity than did adults without cancer (311 vs 338 min/d; P<.001), more sedentary time (532 vs 507 min/d; P=.003), and more prolonged sedentary time (210 vs 184 min/d; P=.002).
Contrary to findings from previous research (based on self-reported physical activity), cancer survivors engaged in more (breast) or equivalent (colon) MVPA compared with adults without cancer. Differences between colon cancer survivors and adults without cancer for light activity and sedentary behavior highlight the importance of considering the full activity spectrum in the context of cancer control.
评估通过加速度计测量的癌症幸存者与无癌症成年人在中度至剧烈强度身体活动（MVPA）、轻度身体活动及久坐时间方面的差异。
将从241名乳腺癌幸存者（ACCEL - 乳腺癌研究，2013年）和171名结肠癌幸存者（ACCEL - 结肠癌研究，2012 - 2013年）收集的加速度计数据，与从无癌症成年人（澳大利亚糖尿病、肥胖与生活方式加速度计子研究，2011 - 2012年）收集的数据合并。采用线性回归估计癌症幸存者与无癌症成年人在身体活动和久坐行为水平上的差异，并对潜在混杂因素进行校正。
乳腺癌幸存者的平均MVPA显著高于未患癌症的女性（分别为29分钟/天和22分钟/天；P <.001）。结肠癌幸存者的轻度活动水平显著低于无癌症成年人（分别为311分钟/天和338分钟/天；P <.001），久坐时间更长（分别为532分钟/天和507分钟/天；P =.003），且久坐持续时间更长（分别为210分钟/天和184分钟/天；P =.002）。
与之前基于自我报告身体活动的研究结果相反，与无癌症成年人相比，癌症幸存者进行了更多（乳腺癌）或相当（结肠癌）的MVPA。结肠癌幸存者与无癌症成年人在轻度活动和久坐行为方面的差异凸显了在癌症控制背景下考虑整个活动谱的重要性。
