背景：大量的初步研究已经测试了增加成人心血管疾病患者身体活动（PA）的干预措施。本荟萃分析整合了关于如何增加心脏样本中PA的现有研究。方法：广泛检索已发表和未发表的测量PA结果的干预研究。结果根据初步研究进行编码。固定效应和随机效应元分析程序包括调节分析。结果：从79份合格的研究报告中综合了11,877名受试者的数据。两组比较的总体平均PA效应大小为0.35（治疗组的平均值高于对照组），这与治疗组1984 kcal/周与对照组1615 kcal/周的差异是一致的。两组比较的适应度效应值为0.17。其他统计学上显著正的两组效应量为。24小时的生活质量和。23例为后续心脏事件。人体测量测量和血压的效应量与0没有显著差异。探索性调节分析发现，在以下研究中，PA的效应量很大：(1)专门关注PA与多种健康行为，(2)干预者与受试者之间更多的接触，(3)有监督的锻炼课程，(4)健康测试，(5)面对面接触与介导的干预传递，以及(6)每周更多的活动分钟。效应大小与资助状况、传播媒介、性别分布或损耗率无关。结论：这些发现证明干预措施可以有效地增加心血管疾病患者的PA。初步研究应比较随机试验中的干预措施，以确认因果关系。2008爱思唯尔爱尔兰有限公司版权所有。
Background: Extensive primary research has tested interventions to increase physical activity (PA) among adults with cardiovascular disease. This meta-analysis integrates the extant research about how to increase PA in cardiac samples.Methods: Extensive literature searching located published and unpublished intervention studies that measured PA outcomes. Results were coded from primary studies. Fixed-and random-effects meta-analytic procedures included moderator analyses.Results: Data were synthesized across 11,877 subjects from 79 eligible research reports. The overall mean PA effect size for 2-group comparisons was 0.35 (higher mean for treatment than control), which is consistent with a difference of 1984 kcal/week for treatment subjects versus 1615 for control subjects. The fitness effect size for 2-group comparisons was .17. Other statistically significantly positive 2-group effect sizes were .24 for quality of life and .23 for subsequent cardiac events. Effect sizes for anthropometric measures and blood pressure did not differ significantly from 0. Exploratory moderator analyses found large effect sizes for PA among studies that had (1) an exclusive focus on PA versus diverse health behaviors, (2) more contact between interventionists and subjects, (3) supervised exercise sessions, (4) fitness testing, (5) face-to-face encounters versus mediated intervention delivery, and (6) more minutes of activity per week. Effect sizes were unrelated to funding status, dissemination vehicle, gender distribution, or attrition rate.Conclusions: These findings document that interventions can be effective in increasing PA among patients with cardiovascular diseases. Primary research should compare interventions in randomized trials to confirm causal relationships. (c) 2008 Elsevier Ireland Ltd. All rights reserved.
