背景资料：尽管参与了心脏康复计划，但在心脏事件发生后的一年内，运动参与率呈下降趋势。目的：本研究的CHANGE目的是测试e（通过应用新目标和经验改变习惯）的有效性，这是一种生活方式改变计划，旨在增加心脏康复计划后一年的运动维持。CHANGE干预包括5个小组认知行为变化咨询会议，参与者被教导自我效能增强解决问题的技能，以及预防复发策略，以解决运动维持问题。方法：参与者（N = 250）被随机分配到CHANGE干预（补充常规护理）或仅常规护理组。使用便携式手表心率监测器测量运动，在运动期间佩戴1年，Cox比例风险回归用于确定研究组之间在研究年内运动的差异。结果如下：在调整了显著协变量种族、性别、合并症肌肉和关节疼痛以及基线动机后，常规护理组的参与者在心脏康复计划后一年内停止锻炼的可能性比CHANGE组高76%（风险比= 1.76，95%置信区间= 1.08-2.86，p = 0.02）。然而，大多数参与者的运动量和强度低于推荐水平。结论：使用当代行为改变策略的咨询干预，如CHANGE干预，可以减少心脏事件后不锻炼的人数。
Background: Despite participation in a cardiac rehabilitation program, there is a downward trajectory of exercise participation during the year following a cardiac event. Purpose: The effectiveness of CHANGE purpose of this study was to test the e (Change Habits by Applying New Goals and Experiences), a life-style modification program designed to increase exercise maintenance in the year following a cardiac rehabilitation program. The CHANGE intervention consists of 5 small-group cognitive-behavioral change counseling sessions in which participants are taught self-efficacy enhancement problem-solving skills, and relapse prevention strategies to address exercise maintenance problems. Method: Participants (N = 250) were randomly assigned to the CHANGE intervention (supplemental to usual care) or a usual-care-only group. Exercise was measured using portable wristwatch heart rate monitors worn during exercise for 1 year Coxproportional hazards regression was used to determine differences in exercise over the study year between the study groups. Results: Participants in the usual-care group were 76% more likely than those in the CHANGE group to stop exercising during the year following a cardiac rehabilitation program (hazard ratio = 1.76, 95% confidence interval = 1.08-2.86, p =.02) when adjusting for the significant covariates race, gender, comorbidity muscle and joint pain, and baseline motivation. Most participants, however had less than recommended levels of exercise amount and intensity. Conclusions: Counseling interventions that use contemporary behavior change strategies, such as the CHANGE intervention, can reduce the number of individuals who do not exercise following cardiac events.
