Abstract

BACKGROUND

Higher levels of physical activity are associated with better functional status, fewer hospital admissions, and lower mortality. In this pilot study, we examined the feasibility and safety of a novel program that combines a pedometer with a website to increase walking.

METHODS

27 persons with stable COPD wore the Omron HJ-720ITC pedometer and used the website for 90 days. They uploaded step-count data to the study server using their home computer and received an email each week with their individualized step-count goal. The website provided step-count feedback, education, and motivational content. Subjects participated in a monthly semi-structured interview by telephone. Subjects reported changes in medical condition by telephone or on the website. Paired T-tests assessed change in daily step counts.

RESULTS

Subjects were males, mean age 72 ± 8 years, with moderate COPD, FEV(1) 1.57 ± 0.48 L (55 ± 16% predicted). 87% and 65% reported no problems using the pedometer and website, respectively. At month 3, 96% reported it was true that they knew their step count goal every day, and 52% reported that they were able to reach their goal. 95% of participants said they would recommend the walking program to another person with COPD. Eight subjects experienced breathing problems unrelated to the intervention. In 24 subjects with step counts at baseline and month 3, there was a significant increase of 1263 steps per day (approximately 1.0 km), p = 0.0054.

CONCLUSIONS

The use of a website and pedometer was feasible and safe, and persons increased their daily walking.

摘要

背景

更高水平的身体活动与更好的功能状态、更少的住院治疗和更低的死亡率有关。在这项初步研究中，我们检验了一种新的方案，该方案将计步器与网站相结合以增加步行量，其可行性和安全性。

方法

27 名稳定期 COPD 患者佩戴 Omron HJ-720ITC 计步器并使用该网站 90 天。他们使用家用计算机将步数数据上传到研究服务器，并每周收到一封电子邮件，其中包含个性化的步数目标。该网站提供步数反馈、教育和激励内容。参与者通过电话每月参加一次半结构化访谈。患者通过电话或网站报告医疗状况的变化。配对 t 检验评估了日常步数的变化。

结果

受试者均为男性，平均年龄 72 ± 8 岁，患有中度 COPD，FEV1 为 1.57 ± 0.48 L（55 ± 16%预计值）。分别有 87%和 65%的患者报告在使用计步器和网站方面没有问题。在第 3 个月，96%的患者报告每天都知道自己的目标步数，52%的患者报告能够达到目标。95%的参与者表示会向另一位 COPD 患者推荐该步行计划。8 名患者出现与干预无关的呼吸问题。在 24 名具有基线和第 3 个月步数值的患者中，每日步数显著增加了 1263 步（约 1.0 公里），p = 0.0054。
