Effectiveness of technology-based interventions to improve physical activity (PA) in people with COPD is controversial. Mixed results may be due to participants' characteristics influencing their use of and engagement with mobile health apps. This study compared demographic, clinical, physical and PA characteristics of patients with COPD using and not using mobile apps in daily life. Patients with COPD who used smartphones were asked about their sociodemographic and clinic characteristics, PA habits and use of mobile apps (general and PA-related). Participants performed a six-minute walk test (6MWT), gait speed test and wore an accelerometer for 7 days. Data were compared between participants using (App Users) and not using (Non-App Users) mobile apps. A sub-analysis was conducted comparing characteristics of PA-App Users and Non-Users. 59 participants were enrolled (73% Male; 66.3 ± 8.3 yrs; FEV 48.7 ± 18.4% predicted): 59% were App Users and 25% were PA-App Users. Significant differences between App Users and Non-App Users were found for age (64.2 ± 8.9 vs. 69.2 ± 6.3yrs), 6MWT (462.9 ± 91.7 vs. 414.9 ± 82.3 m), Gait Speed (Median 1.5 [Q1-Q3: 1.4-1.8] vs. 2.0 [1.0-1.5]m/s), Time in Vigorous PA (0.6 [0.2-2.8] vs. 0.14 [0.1-0.7]min) and Self-Reported PA (4.0 [1.0-4.0] vs. 1.0 [0.0-4.0] Points). Differences between PA-App Users and Non-Users were found in time in sedentary behavior (764.1 [641.8-819.8] vs. 672.2 [581.2-749.4] min) and self-reported PA (4.0 [2.0-6.0] vs. 2.0 [0.0-4.0] points). People with COPD using mobile apps were younger and had higher physical capacity than their peers not using mobile apps. PA-App Users spent more time in sedentary behaviors than Non-Users although self-reporting more time in PA.
基于技术的干预措施对改善慢性阻塞性肺疾病（COPD）患者身体活动（PA）的有效性存在争议。结果参差不齐可能是由于参与者的特征影响了他们对移动健康应用程序的使用和参与度。本研究比较了日常生活中使用和不使用移动应用程序的COPD患者的人口统计学、临床、身体和PA特征。询问使用智能手机的COPD患者其社会人口统计学和临床特征、PA习惯以及移动应用程序（一般应用程序和与PA相关的应用程序）的使用情况。参与者进行了六分钟步行测试（6MWT）、步态速度测试，并佩戴加速度计7天。比较了使用移动应用程序的参与者（应用程序用户）和不使用移动应用程序的参与者（非应用程序用户）的数据。进行了一项亚分析，比较了PA应用程序用户和非用户的特征。共招募了59名参与者（73%为男性；66.3±8.3岁；预测FEV为48.7±18.4%）：59%为应用程序用户，25%为PA应用程序用户。应用程序用户和非应用程序用户在年龄（64.2±8.9岁与69.2±6.3岁）、6MWT（462.9±91.7米与414.9±82.3米）、步态速度（中位数1.5[四分位间距：1.4 - 1.8]米/秒与2.0[1.0 - 1.5]米/秒）、剧烈PA时间（0.6[0.2 - 2.8]分钟与0.14[0.1 - 0.7]分钟）和自我报告的PA（4.0[1.0 - 4.0]分与1.0[0.0 - 4.0]分）方面存在显著差异。PA应用程序用户和非用户在久坐行为时间（764.1[641.8 - 819.8]分钟与672.2[581.2 - 749.4]分钟）和自我报告的PA（4.0[2.0 - 6.0]分与2.0[0.0 - 4.0]分）方面存在差异。使用移动应用程序的COPD患者比不使用移动应用程序的同龄人更年轻，身体能力更高。PA应用程序用户虽然自我报告的PA时间更多，但久坐行为的时间比非用户更长。
