BACKGROUND
The SenseWear Armband (SWA) provides simple and non-invasive measures of energy expenditure (EE) during physical activity, however its accuracy in adults with cystic fibrosis (CF) during free living physical activities has not been established.
METHODS
26 CF adults (mean FEV1 63% predicted; 11 males) completed a series of standardised static and active tasks with simultaneous analysis of EE via the SWA and indirect calorimetry (IC).
RESULTS
Mean difference and limits of agreement between EE values from the SWA and IC across all activities were -0.02METs (95% CI -1.1 to 1.1). There was moderate agreement between the two measures (ICC 0.4; 95% CI: 0 to 0.7; p=0.03). For individual activity tasks ICC ranged from 0.1 to 0.6.
CONCLUSION
Overall, the SWA demonstrated good agreement with IC for EE estimates in CF adults during a series of free-living activities, however accuracy was variable when assessing EE for specific activities of shorter duration.
背景
SenseWear臂带（SWA）可在身体活动期间提供简单且无创的能量消耗（EE）测量值，然而其在成年囊性纤维化（CF）患者自由生活身体活动期间的准确性尚未得到证实。
方法
26名成年CF患者（预计平均FEV1为63%；11名男性）完成了一系列标准化的静态和动态任务，同时通过SWA和间接量热法（IC）分析EE。
结果
在所有活动中，SWA和IC得出的EE值之间的平均差异和一致性界限为-0.02梅脱（95%可信区间-1.1至1.1）。两种测量方法之间存在中度一致性（ICC 0.4；95%可信区间：0至0.7；p=0.03）。对于个体活动任务，ICC范围为0.1至0.6。
结论
总体而言，在一系列自由生活活动中，SWA在成年CF患者的EE估计方面与IC显示出良好的一致性，然而在评估较短持续时间的特定活动的EE时，准确性存在差异。
