Abstract

OBJECTIVE

We created a tool for assessing physical activity (PA), the Acti'MET calculator, to quickly estimate weekly energy expenditure. This study aimed to assess the metrological properties of the tool in cardiac rehabilitation (CR).

METHODS

Two examiners evaluated the reliability and concurrent validity of the tool with cardiac patients. The validity of the tool was assessed by comparison with other classical methods for measurement of PA such as the Dijon Physical Activity Score (PAS) and the International Physical Activity Questionnaire (IPAQ) score, the 6-min walk test (6MWT) and the cardiopulmonary maximal exercise test. Correlation was assessed by Pearson or Spearman correlation analysis.

RESULTS

For the 36 cardiac patients (mean age 55±11 years, 24 men), inter-rater and intra-rater reliabilities were strong: r=0.87 and r=0.98, respectively, both P<0.0001. We found a strong correlation of the Acti'MET score with the IPAQ score (r=0.88, P<0.0001), moderate correlation with the PAS (r=0.39, P<0.05) and 6MWT (r=0.54, P<0.01), and no correlation with peak power output.

CONCLUSION

The Acti'MET calculator is reliable, valid and easy to use for assessing PA in CR. This tool seems to well reflect the weekly PA, unlike the PAS, which evaluates PA on a yearly basis.

摘要

目的

我们创建了一个用于评估身体活动（PA）的工具——Acti'MET计算器，以快速估算每周的能量消耗。本研究旨在评估该工具在心脏康复（CR）中的计量特性。

方法

两名检查者评估该工具在心脏病患者中的可靠性和同时效度。通过与其他测量PA的经典方法进行比较来评估该工具的效度，这些方法包括第戎身体活动评分（PAS）、国际身体活动问卷（IPAQ）评分、6分钟步行试验（6MWT）和心肺运动最大试验。通过Pearson或Spearman相关分析评估相关性。

结果

对于36名心脏病患者（平均年龄55±11岁，24名男性），评分者间和评分者内的可靠性都很强：分别为r=0.87和r=0.98，均P<0.0001。我们发现Acti'MET评分与IPAQ评分有很强的相关性（r=0.88，P<0.0001），与PAS有中度相关性（r=0.39，P<0.05），与6MWT有中度相关性（r=0.54，P<0.01），与峰值功率输出无相关性。
