Patients who have completed Phase II cardiac rehabilitation have low rates of maintenance of exercise after program completion, despite the importance of sustaining regular exercise to prevent future cardiac events.
The efficacy of a home-based intervention to support exercise maintenance among patients who had completed Phase II cardiac rehabilitation versus contact control was evaluated.
An RCT was used to evaluate the intervention. Data were collected in 2005-2010 and analyzed in 2010.
SETTING/PARTICIPANTS: One hundred thirty patients (mean age=63.6 years [SD=9.7], 20.8% female) were randomized to exercise counseling (Maintenance Counseling group, n=64) or contact control (Contact Control group, n=66).
Maintenance Counseling group participants received a 6-month program of exercise counseling (based on the transtheoretical model and social cognitive theory) delivered via telephone, as well as print materials and feedback reports.
Assessments of physical activity (7-Day Physical Activity Recall), motivational readiness for exercise, lipids, and physical functioning were conducted at baseline, 6 months, and 12 months. Objective accelerometer data were collected at the same time points. Fitness was assessed via maximal exercise stress tests at baseline and 6 months.
The Maintenance Counseling group reported significantly higher exercise participation than the Contact Control group at 12 months (difference of 80 minutes, 95% CI=22, 137). Group differences in exercise at 6 months were nonsignificant. The intervention significantly increased the probability of participants' exercising at or above physical activity guidelines and attenuated regression in motivational readiness versus the Contact Control Group at 6 and 12 months. Self-reported physical functioning was significantly higher in the Maintenance Counseling group at 12 months. No group differences were seen in fitness at 6 months or lipid measures at 6 and 12 months.
A telephone-based intervention can help maintain exercise, prevent regression in motivational readiness for exercise, and improve physical functioning in this patient population.
尽管定期运动对于预防未来的心脏事件至关重要，但完成第二期心脏康复的患者在完成康复计划后，维持运动的比例仍然较低。
评估家庭干预对完成第二期心脏康复的患者维持运动的效果，与对照组（接触控制）相比。
使用 RCT 评估干预效果。数据于 2005-2010 年收集，并于 2010 年进行分析。
地点/参与者：130 名患者（平均年龄 63.6 岁 [标准差 9.7]，20.8%为女性）被随机分为运动咨询组（维持咨询组，n=64）或接触控制组（接触控制组，n=66）。
维持咨询组的参与者接受了 6 个月的运动咨询计划（基于跨理论模型和社会认知理论），通过电话进行，同时提供印刷材料和反馈报告。
在基线、6 个月和 12 个月时进行体力活动评估（7 天体力活动回忆）、运动动机准备度、血脂和身体机能。同时在相同时间点收集客观加速度计数据。在基线和 6 个月时进行最大运动压力测试评估体能。
维持咨询组在 12 个月时报告的运动参与率明显高于接触控制组（差异 80 分钟，95%置信区间 22，137）。6 个月时两组之间的运动差异无统计学意义。与接触控制组相比，该干预措施显著增加了参与者达到或超过体力活动指南的可能性，并在 6 个月和 12 个月时减轻了运动动机准备度的回归。在 12 个月时，维持咨询组的自我报告身体机能明显更高。在 6 个月时，两组在体能方面没有差异，在 6 个月和 12 个月时，两组在血脂方面也没有差异。
基于电话的干预可以帮助维持运动，防止运动动机准备度的下降，并改善该患者群体的身体机能。
