2003-2004年和2005-2006年的国家健康和营养检查调查（NHANES）是第一个纳入客观测量的身体活动和久坐行为的人口水平研究，从而更好地了解这些行为。然而，尚未对癌症幸存者的这些数据进行全面检查，包括所有癌症类型的短期和长期幸存者。因此，本分析的目的是使用这些数据来描述各种类型的短期和长期癌症幸存者的活动行为。第二个目的是比较癌症幸存者与一般人群的活动模式。癌症幸存者（n = 508）和年龄匹配的未诊断为癌症的个体（n = 1，016）是从通过加速度计测量活动的成年人子样本中确定的。在癌症类型和人口统计学中总结了身体活动和久坐行为;使用多变量回归来评估幸存者和未诊断出癌症的人之间的差异。癌症幸存者平均年龄为61.4岁（95% CI：59.6，63.2）; 57%为女性。身体活动和久坐不动的行为模式因癌症诊断、人口统计学变量和诊断后的时间而异。幸存者进行307分钟/天的轻度体力活动（95% CI：295，319），16分钟/天的中等强度的活动（95% CI：14，17）;只有8%符合体力活动的建议。这些人还报告了519分钟（CI：506，532）的久坐时间，每天有86次（CI：84，88）久坐行为。与非癌症幸存者相比，在调整潜在的混杂因素后，幸存者进行更少的光强度活动（P = 0.01），更多的久坐（P = 0.01），久坐时间的休息时间更少（P = 0.04），尽管在任何其他活动变量中没有差异。这些结果表明，癌症幸存者活动不足。相对于没有被诊断出患有癌症的同龄成年人，他们久坐的时间更多，休息的时间更少。因此，久坐行为和轻度活动可能是重要的干预目标，特别是对于那些不太接受中度到剧烈活动的人。
The 2003–2004 and 2005–2006 cycles of the National Health and Nutrition Examination Survey (NHANES) were among the first population-level studies to incorporate objectively measured physical activity and sedentary behavior, allowing for greater understanding of these behaviors. However, there has yet to be a comprehensive examination of these data in cancer survivors, including short- and long-term survivors of all cancer types. Therefore, the purpose of this analysis was to use these data to describe activity behaviors in short- and long-term cancer survivors of various types. A secondary aim was to compare activity patterns of cancer survivors to that of the general population. Cancer survivors (n = 508) and age-matched individuals not diagnosed with cancer (n = 1,016) were identified from a subsample of adults with activity measured by accelerometer. Physical activity and sedentary behavior were summarized across cancer type and demographics; multivariate regression was used to evaluate differences between survivors and those not diagnosed with cancer. On average, cancer survivors were 61.4 (95% CI: 59.6, 63.2) years of age; 57% were female. Physical activity and sedentary behavior patterns varied by cancer diagnosis, demographic variables, and time since diagnosis. Survivors performed 307 min/day of light-intensity physical activity (95% CI: 295, 319), 16 min/day of moderate-vigorous intensity activity (95% CI: 14, 17); only 8% met physical activity recommendations. These individuals also reported 519 (CI: 506, 532) minutes of sedentary time, with 86 (CI: 84, 88) breaks in sedentary behavior per day. Compared to non-cancer survivors, after adjustment for potential confounders, survivors performed less light-intensity activity (P = 0.01), were more sedentary (P = 0.01), and took fewer breaks in sedentary time (P = 0.04), though there were no differences in any other activity variables. These results suggest that cancer survivors are insufficiently active. Relative to adults of similar age not diagnosed with cancer, they engage in more sedentary time with fewer breaks. As such, sedentary behavior and light-intensity activity may be important intervention targets, particularly for those for whom moderate-to-vigorous activity is not well accepted.
