Identification of the factors that influence sedentary behaviour in older adults is important for the design of appropriate intervention strategies. In this study, we determined the prevalence of sedentary behaviour and its association with physical, cognitive, and psychosocial status among older adults residing in Assisted Living (AL).
Participants ( = 114, mean age = 86.7) from AL sites in British Columbia wore waist-mounted activity monitors for 7 consecutive days, after being assessed with the Timed Up and Go (TUG), Montreal Cognitive Assessment (MoCA), Short Geriatric Depression Scale (GDS), and Modified Fall Efficacy Scale (MFES).
On average, participants spent 87% of their waking hours in sedentary behaviour, which accumulated in 52 bouts per day with each bout lasting an average of 13 minutes. Increased sedentary behaviour associated significantly with scores on the TUG ( = 0.373, < 0.001) and MFES ( = -0.261, = 0.005), but not with the MoCA or GDS. Sedentary behaviour also associated with male gender, use of mobility aid, and multiple regression with increased age.
We found that sedentary behaviour among older adults in AL associated with TUG scores and falls-related self-efficacy, which are modifiable targets for interventions to decrease sedentary behaviour in this population.
确定影响老年人久坐行为的因素对于制定适当的干预策略非常重要。在这项研究中，我们确定了居住在辅助生活（Assisted Living，AL）中的老年人久坐行为的流行率及其与身体、认知和心理社会状况的相关性。
不列颠哥伦比亚省 AL 地点的参与者（n=114，平均年龄=86.7）佩戴腰部活动监测器，连续 7 天，然后进行计时起立行走测试（Timed Up and Go，TUG）、蒙特利尔认知评估（Montreal Cognitive Assessment，MoCA）、简短老年抑郁量表（Short Geriatric Depression Scale，GDS）和改良跌倒效能量表（Modified Fall Efficacy Scale，MFES）评估。
平均而言，参与者在清醒时间中有 87%处于久坐行为状态，每天累计 52 次，每次持续约 13 分钟。久坐行为与 TUG 评分（ = 0.373， < 0.001）和 MFES 评分（ = -0.261， = 0.005）显著相关，但与 MoCA 或 GDS 无关。久坐行为还与男性性别、使用助行器以及与年龄增加的多元回归相关。
我们发现 AL 中的老年人久坐行为与 TUG 评分和与跌倒相关的自我效能感相关，这是针对该人群减少久坐行为的干预措施的可调节目标。
