Breast cancer survivors (BCS) engage in more sedentary behavior (SED) than those without cancer. However, the context in which SED is accrued is unknown. The purpose of this study is to examine differences in total and domain-specific SED of BCS and healthy controls. 20 BCS and 20 age-matched, healthy controls wore ActiGraph GT3X + accelerometers to measure SED and activity. Participants self-reported SED for transportation, occupational, screen time and leisure purposes. Multiple linear regressions were used to estimate differences in SED between BCS and controls. BCS spent significantly more time watching TV (152.4 vs. 60.3; p < 0.01) and less time in total SED (490.8 vs. 587.4; p = 0.046) and other leisure activities (57.6 vs. 106.9; p < 0.01) than healthy controls. BCS engage in more TV watching and less time in other leisure activities than controls, thus interventions should focus on reducing TV time. Understanding facilitators of TV viewing is needed to determine specific intervention targets.

乳腺癌幸存者（BCS）的久坐行为（SED）比没有癌症的幸存者多。但是，SED产生的上下文是未知的。这项研究的目的是检查BCS和健康对照组的总SED和特定领域SED的差异。20位BCS和20位年龄匹配的健康对照者穿着ActiGraph GT3X +加速度计来测量SED和活动。参与者自行报告了SED，用于交通，职业，放映时间和休闲目的。多元线性回归用于估计BCS和对照之间SED的差异。BCS在电视上花费的时间明显更多（152.4比60.3；p  <0.01），而在SED的总时间（490.8比587.4；p  = 0.046）和其他休闲活动上的时间更少（57.6 vs 106.9；p <0.01）高于健康对照组。与控制相比，BCS可以观看更多电视节目，而在其他休闲活动中所花的时间更少，因此干预措施应着重于减少电视时间。需要了解电视收看主持人，以确定特定的干预目标。
