We examined differences in the volume and pattern of physical activity (PA) and sedentary behavior between adults with and without stroke.
We studied cohort members with an adjudicated or self-reported stroke (n=401) and age-, sex-, race-, region of residence-, and body mass index-matched participants without a history of stroke (n=1203) from the REGARDS study (Reasons for Geographic and Racial Differences in Stroke). Sedentary behavior (total volume and bouts), light-intensity PA, and moderate-to-vigorous-intensity PA were objectively measured for 7 days via hip-worn accelerometer.
Sedentary time (790.5±80.4 versus 752.4±81.9 min/d) and mean sedentary bout duration (15.7±12.6 versus 11.9±8.1 min/d) were higher and PA (light-intensity PA: 160.5±74.6 versus 192.9±73.5 min/d and moderate-to-vigorous-intensity PA: 9.0±11.9 versus 14.7±17.0 min/d) lower for stroke survivors compared with controls (P<0.001). Stroke survivors also accrued fewer activity breaks (65.5±21.9 versus 73.31±18.9 breaks/d) that were shorter (2.4±0.7 versus 2.7±0.8 minutes) and lower in intensity (188.4±60.8 versus 217.9±72.2 counts per minute) than controls (P<0.001).
Stroke survivors accrued a lower volume of PA, higher volume of sedentary time, and exhibited accrual patterns of more prolonged sedentary bouts and shorter, lower intensity activity breaks compared with persons without stroke.
我们研究了有和无卒中成年人之间体力活动（PA）和久坐行为的量和模式的差异。
我们研究了 REGARDS 研究（地理和种族差异导致卒中的原因）中经裁定或自我报告有卒中（n=401）和年龄、性别、种族、居住地区和体重指数匹配的无卒中史参与者（n=1203）的队列成员。通过佩戴在髋部的加速度计，7 天内客观测量久坐行为（总时长和时间片段）、低强度 PA 和中高强度 PA。
与对照组相比，卒中幸存者的久坐时间（790.5±80.4 分钟/天与 752.4±81.9 分钟/天）和平均久坐时间片段（15.7±12.6 分钟/片段与 11.9±8.1 分钟/片段）更高，PA（低强度 PA：160.5±74.6 分钟/天与 192.9±73.5 分钟/天和中高强度 PA：9.0±11.9 分钟/天与 14.7±17.0 分钟/天）更低（P<0.001）。与对照组相比，卒中幸存者的活动休息次数也较少（65.5±21.9 次/天与 73.31±18.9 次/天），休息时间较短（2.4±0.7 分钟与 2.7±0.8 分钟），强度较低（188.4±60.8 次/分钟与 217.9±72.2 次/分钟）（P<0.001）。
与无卒中的人相比，卒中幸存者的 PA 量较低，久坐时间较多，久坐时间片段更长，活动休息时间更短，强度更低。
