摘要
背景与目的:体力活动可以延缓居住在生活护理机构的老年人自我照顾障碍的进展。尽管如此,居住在生活护理机构的老年人大部分时间都是久坐不动的,没有达到建议的身体活动标准,这可能导致这一人群中自我护理障碍的增加。在本研究中,我们旨在确定居住在生活护理机构的老年人的中高强度身体活动(MVPA)是否会调节久坐时间与自我照顾能力之间的关联。方法:用加速度计测量久坐时间和MVPA。采用Barthel指数评估自理能力。采用多元回归模型探讨久坐时间与MVPA交互作用对被试自理能力的影响。然后使用约翰逊-内曼技术来估计确切的MVPA阈值,在该阈值下,久坐时间对自我照顾能力的影响变得不显著。结果:我们发现久坐时间对自我照顾功能障碍有显著影响(标准化β=-1.66;95% CI为-1.77 ~ -1.54,P = 0.013)。结果表明,MVPA调节了自我照顾残疾状态与久坐时间的关系(标准化β= 1.14;95% CI 1.13 ~ 1.14, P = 0.032)。Johnson-Neyman技术确定51分钟/天的MVPA可以抵消久坐时间对自我照顾障碍的负面影响。结论:我们的研究结果表明,物理治疗师应注重减少久坐时间和身体活动,以防止居住在生活护理机构的八十多岁老人发展为依赖。
Can Physical Activity Make Up for the Self-Care Disability Effects of Too Much Sitting? A Moderation Analysis in Octogenarians Residing in Living Care Facilities.
Background and purpose: Physical activity can delay the progression of self-care disability in older adults residing in living care facilities. Nonetheless, older adults residing in living care facilities spend most of their time sedentary and do not meet the physical activity recommendation, which may result in increasing self-care disability in this population group. In this study, we aimed to determine whether the association between sedentary time and self-care disability was moderated by moderate-to-vigorous physical activity (MVPA) in older adults residing in living care facilities.
Methods: Sedentary time and MVPA were both measured with accelerometers. Self-care disability was assessed with the Barthel Index. A multivariate regression model was used to ascertain the effects of the interaction between sedentary time and MVPA on the self-care disability of participants. The Johnson-Neyman technique was then used to estimate the exact MVPA threshold at which the effect of sedentary time on self-care disability became nonsignificant.
Results: We found a significant effect of sedentary time on self-care disability (standardized β=-1.66; 95% CI -1.77 to -1.54, P = .013). Results indicated that MVPA moderates the relationship between self-care disability status and sedentary time (standardized β= 1.14; 95% CI 1.13 to 1.14, P = .032). The Johnson-Neyman technique determined that 51 min/day of MVPA would offset the negative effects of sedentary time on self-care disability.
Conclusions: Our results suggest physical therapists should focus on reducing sedentary time alongside physical activity to prevent the progression to dependency in octogenarians residing in living care facilities.
