Research suggests that cardiac rehabilitation (CR) patients need to engage in at least 6500 steps per day to obtain health benefits. Unfortunately, very little is known about the steps-per-day trajectories of these patients and whether the demographic, clinical, and CR program characteristics are similar for these trajectories.
Patients (n = 235) completed a questionnaire assessing demographic and clinical variables upon entry to CR and subsequently wore a pedometer for 7 days at the end of CR, and 3, 6, and 9 months after completing CR.
Latent class growth analyses showed that 3 classes of patients emerged that were termed nonadherers (averaged ∼3112 steps per day at the end of CR and remained stable up to 9 months after CR), significant decliners (averaged ∼7010 steps per day at the end of CR and steadily declined after CR), and optimal adherers (averaged ∼10 700 steps per day and remained stable after CR). Logistic regressions showed that nonadherers were more likely to be obese, have at least 1 comorbidity, and a lower exercise capacity compared with the significant decliners/optimal adherers.
Distinct steps-per-day trajectories exist for CR patients that are partially distinguished by demographic and clinical variables.
研究表明，心脏康复（CR）患者每天至少需要走6500步才能获得健康益处。不幸的是，对于这些患者的每日步数轨迹以及这些轨迹的人口统计学、临床和CR项目特征是否相似，我们知之甚少。
患者（n = 235）在进入CR时完成了一份评估人口统计学和临床变量的问卷，随后在CR结束时佩戴计步器7天，并在完成CR后的3、6和9个月佩戴。
潜在类别增长分析显示，出现了3类患者，分别称为不依从者（CR结束时平均每天约3112步，CR后9个月内保持稳定）、显著下降者（CR结束时平均每天约7010步，CR后稳步下降）和最佳依从者（平均每天约10700步，CR后保持稳定）。逻辑回归显示，与显著下降者/最佳依从者相比，不依从者更有可能肥胖、至少有一种合并症且运动能力较低。
CR患者存在不同的每日步数轨迹，这些轨迹在一定程度上由人口统计学和临床变量区分。
