Understanding factors that influence the amount of time people with stroke spend sitting and being active is important to inform the development of targeted interventions.
To explore the physical, cognitive, and psychosocial factors associated with daily sitting time and physical activity in people with stroke.
Secondary analysis of an observational study (n = 50, mean age 67.2 ± 11.6 years, 33 men) of adults at least 6 months post-stroke. Activity monitor data were collected via a 7-day, continuous wear (24 hours/day) protocol. Sitting time [total, and prolonged (time in bouts of ≥ 30 minutes)] was measured with an activPAL3 activity monitor. A hip-worn Actigraph GT3X+ accelerometer was used to measure moderate-to-vigorous-intensity physical activity (MVPA) time. Univariate analyses examined relationships of stroke severity (National Institutes of Health Stroke Scale), physical [walking speed, Stroke Impact Scale (SIS) physical domain score], cognitive (Montreal Cognitive Assessment), and psychosocial factors (living arrangement, SIS emotional domain score) with sitting time, prolonged sitting time, and MVPA.
Self-reported physical function and walking speed were negatively associated with total sitting time (r = - 0.354, P = 0.022 and r = - 0.361, P = 0.011, respectively) and prolonged sitting time (r = - 0.5, P = 0.001 and - 0.45, P = 0.001, respectively), and positively associated with MVPA (r = 0.469, P = 0.002 and 0.431, P = 0.003, respectively).
Physical factors, such as walking ability, may influence sitting and activity time in people with stroke, yet much of the variance in daily sitting time remains unexplained. Large prospective studies are required to understand the drivers of activity and sitting time.
了解影响中风患者久坐时间和活动量的因素对于制定有针对性的干预措施至关重要。
探讨与中风患者每日久坐时间和身体活动相关的身体、认知和心理社会因素。
对一项观察性研究（n = 50，平均年龄67.2±11.6岁，33名男性）进行二次分析，研究对象为中风后至少6个月的成年人。通过7天连续佩戴（每天24小时）方案收集活动监测数据。使用activPAL3活动监测仪测量久坐时间[总计以及久坐时间延长（每次持续≥30分钟的时间）]。使用佩戴在髋部的Actigraph GT3X+加速度计测量中度至剧烈强度身体活动（MVPA）时间。单因素分析研究中风严重程度（美国国立卫生研究院卒中量表）、身体因素[步行速度、卒中影响量表（SIS）身体领域得分]、认知因素（蒙特利尔认知评估）和心理社会因素（居住安排、SIS情感领域得分）与久坐时间、久坐时间延长和MVPA之间的关系。
自我报告的身体功能和步行速度与总久坐时间呈负相关（r = -0.354，P = 0.022和r = -0.361，P = 0.011）以及与久坐时间延长呈负相关（r = -0.5，P = 0.001和-0.45，P = 0.001），并与MVPA呈正相关（r = 0.469，P = 0.002和0.431，P = 0.003）。
身体因素，如步行能力可能会影响中风患者的久坐和活动时间，但每日久坐时间的大部分差异仍无法解释。需要进行大型前瞻性研究以了解活动和久坐时间的驱动因素。
