OBJECTIVES
To characterize patterns of sedentary behavior and physical activity in older adults recovering from hip fracture and to determine characteristics associated with activity.
METHODS
Community-dwelling, Canadian adults (65 years+) who sustained hip fracture wore an accelerometer at the waist for seven days and provided information on quality of life, falls self-efficacy, cognitive functioning, and mobility.
RESULTS
There were 53 older adults (mean age [SD] 79.5 [7.8] years) enrolled in the study; 49 had valid data and demonstrated high levels of sedentary time (median [p10, p90] 591.3 [482.2, 707.2] minutes/day), low levels of light activity (186.6 [72.6, 293.7]), and MVPA (2 [0.1, 27.6]), as well as few daily steps (2467.7 [617.1, 6820.4]). Regression analyses showed that age, gender, gait speed, and time since fracture were associated with outcomes.
CONCLUSIONS
Older adults have long periods of sedentary time with minimal activity. Results are a call to action to encourage people to sit less and move more.
目的
描述髋部骨折康复期老年人的久坐行为和身体活动模式，并确定与活动相关的特征。
方法
居住在社区的65岁及以上加拿大成年人，髋部骨折后在腰部佩戴加速度计7天，并提供有关生活质量、跌倒自我效能、认知功能和活动能力的信息。
结果
53名老年人（平均年龄[标准差]79.5[7.8]岁）参与了该研究；49人有有效数据，显示久坐时间长（中位数[p10，p90]591.3[482.2，707.2]分钟/天）、轻度活动水平低（186.6[72.6，293.7]）、中度至剧烈身体活动（MVPA）水平低（2[0.1，27.6]），以及每日步数少（2467.7[617.1，6820.4]）。回归分析表明，年龄、性别、步速和骨折后的时间与结果相关。
结论
老年人久坐时间长，活动极少。研究结果呼吁采取行动，鼓励人们少坐多动。
