Chronic obstructive pulmonary disease (COPD) patients have lower levels of physical activity compared to age-matched controls, and they limit physical activities requiring normal exertion. Our purpose was to compare the effectiveness of a traditional exercise therapy (TET) program with a behavioral lifestyle activity program (LAP) in promoting physical activity.
Moderate physical activity (kcal/week) was assessed in 176 COPD patients using the Community Health Activities Model for Seniors questionnaire. Patients were randomized to either a three month TET program that meet thrice weekly or a LAP. The LAP was designed to teach behavioral skills that encouraged the daily accumulation of self-selected physical activities of at least moderate intensity. Interventionist contact was similar (36 h) between the two groups. Patients were assessed at baseline and 3, 6 and 12 months.
Compared to baseline values, self-reported moderate physical activity increased three months post-randomization with no significant difference (p = 0.99) found between the TET (2501 +/- 197 kcal/week) and the LAP (2498 +/- 211 kcal/week). At 6 and 12 months post-randomization, there were no significant differences (p = 0.37 and 0.69, respectively) in self-reported levels of moderate physical activity between the TET (2210 +/- 187 and 2213 +/- 218 kcal/week, respectively) and the LAP (2456 +/- 198 and 2342 +/- 232 kcal/week, respectively).
Although there was no difference between treatment groups, the TET and the LAP were both effective at in increasing moderate levels of physical activity at 3 months and maintaining moderate physical activity levels 12 months post-randomization. This clinical trial is registered with ClinicalTrials.gov. Its identifier is NCT00328484.
与年龄匹配的对照组相比，慢性阻塞性肺疾病（COPD）患者的身体活动水平较低，他们限制需要正常用力的身体活动。我们的目的是比较传统运动疗法（TET）方案与行为生活方式活动方案（LAP）在促进身体活动方面的有效性。
使用社区健康活动模式老年人问卷（Community Health Activities Model for Seniors questionnaire）评估 176 名 COPD 患者的适度身体活动（每周千卡数）。患者被随机分为三组，每周接受三次 TET 方案或 LAP 方案。LAP 旨在教授鼓励日常积累至少中等强度的自选身体活动的行为技能。两组之间的干预接触相似（36 小时）。患者在基线和 3、6 和 12 个月时进行评估。
与基线值相比，随机分组后三个月自我报告的适度身体活动增加，但两组之间无显著差异（p = 0.99）。TET（2501 +/- 197 千卡/周）和 LAP（2498 +/- 211 千卡/周）之间。在随机分组后 6 和 12 个月时，TET（2210 +/- 187 和 2213 +/- 218 千卡/周）和 LAP（2456 +/- 198 和 2342 +/- 232 千卡/周）之间自我报告的适度身体活动水平没有显著差异（p = 0.37 和 0.69，分别）。
尽管治疗组之间没有差异，但 TET 和 LAP 均能有效提高 3 个月时的适度身体活动水平，并在随机分组后 12 个月维持适度身体活动水平。这项临床试验在 ClinicalTrials.gov 上注册，其标识符为 NCT00328484。
