The aim of this study was to investigate whether limitation during the performance of activities of daily living (ADL) was associated with life-space mobility in older people with chronic obstructive pulmonary disease (COPD), and to generate a regression model for life-space mobility score.
This cross-sectional study with a convenience sample included older people (aged ≥60 years old) with COPD. We assessed participants' lung function (spirometry), life-space mobility (University of Alabama at Birmingham Study of Aging Life-Space Assessment questionnaire), severity of dyspnea (Modified Dyspnea Index) and limitation during the performance of ADL (London Chest Activity of Daily Living). We used Pearson's correlation to investigate the associations between the measures, and multiple linear regression to detect which of the measures influenced life-space mobility. Statistical significance was set at 5%.
Fifty participants completed all the assessments (29 females [58%]; mean ± SD age of 67 ± 6 years old, FEV 47 ± 29% of predicted, and body mass index 22.5 ± 11.6 kg/m). Their mean scores for life-space mobility and for limitation during the performance of ADL were 49.7 ± 27.2 and 16.46 ± 9.74, respectively. We found a strong inverse correlation between limitation during the performance of ADL and life-space mobility (r = -0.57, p = <0.01) as well as between severity of dyspnea and life-space mobility (r= 0.86, p= <0.01). Both sex and limitation during the performance of ADL were considered as independent factors associated to life-space mobility (R= 0.56).
In this study, limitations during the performance of ADL and dyspnea had a strong correlation with life-space mobility in older adults with COPD. Also, alongside sex, the limitation during the performance of ADL is an independent factor associated with life-space mobility in a regression model.
本研究旨在探讨慢性阻塞性肺疾病（COPD）老年人日常生活活动（ADL）受限是否与生活空间移动性相关，并建立生活空间移动性评分的回归模型。
本横断面研究采用便利抽样法纳入了老年 COPD 患者（年龄≥60 岁）。我们评估了参与者的肺功能（肺量计）、生活空间移动性（伯明翰阿拉巴马大学衰老生活空间评估问卷）、呼吸困难严重程度（改良呼吸困难指数）和 ADL 执行受限情况（伦敦胸部 ADL 量表）。我们使用 Pearson 相关分析来探讨这些指标之间的关联，并使用多元线性回归来检测哪些指标影响生活空间移动性。统计显著性设为 5%。
50 名参与者完成了所有评估（29 名女性[58%]；平均年龄 67 ± 6 岁，FEV1 占预计值的 47 ± 29%，体重指数 22.5 ± 11.6kg/m2）。他们的生活空间移动性和 ADL 执行受限的平均得分分别为 49.7 ± 27.2 和 16.46 ± 9.74。我们发现 ADL 执行受限与生活空间移动性之间存在强烈的负相关（r=-0.57，p<0.01），以及呼吸困难严重程度与生活空间移动性之间存在强烈的正相关（r=0.86，p<0.01）。性别和 ADL 执行受限均被视为与生活空间移动性相关的独立因素（R2=0.56）。
在这项研究中，ADL 执行受限和呼吸困难与 COPD 老年患者的生活空间移动性密切相关。此外，ADL 执行受限与性别一样，是回归模型中与生活空间移动性相关的独立因素。
