BACKGROUND
Thigh-worn accelerometers can accurately measure time spent sitting, standing and walking in free-living settings.
AIM
To investigate the concurrent validity of a new Fibion accelerometer and a validated ActivPAL4 accelerometer for estimating sedentary and upright time in healthy individuals.
METHODS
A total of 29 healthy individuals, aged between 18 and 50 years, wore the Fibion and ActivPAL4 devices on the same thigh with a medical adhesive tape during one typical weekday. Concurrent validity of the Fibion and ActivPAL4 was assessed by comparing time spent in sitting, walking and standing using intraclass correlation coefficient and Bland-Altman plots.
RESULTS
Intraclass correlation coefficients were ≥0.843 which indicated good to excellent validity between the two devices for measuring sedentary (sitting) and upright (standing and walking) time. Analysis of the Bland Altman plots revealed a reasonable agreement for sitting, standing and walking time between both devices. No proportional bias was evident in the Bland-Altman plots.
CONCLUSION
The Fibion demonstrated good to excellent validity in measuring sedentary and upright time compared to the ActivPAL4 in healthy individuals.
背景
大腿佩戴式加速度计能够准确测量在自由生活环境中坐、站和行走所花费的时间。
目的
研究新型Fibion加速度计与经过验证的ActivPAL4加速度计在估计健康个体久坐时间和直立时间方面的同时效度。
方法
共有29名年龄在18至50岁之间的健康个体，在一个典型工作日期间，使用医用胶带将Fibion和ActivPAL4设备佩戴在同一条大腿上。通过使用组内相关系数和Bland-Altman图比较坐、走和站所花费的时间，评估Fibion和ActivPAL4的同时效度。
结果
组内相关系数≥0.843，表明两种设备在测量久坐（坐）和直立（站和走）时间方面具有良好到极佳的效度。对Bland-Altman图的分析显示，两种设备在坐、站和走的时间方面具有合理的一致性。Bland-Altman图中没有明显的比例偏差。
结论
与ActivPAL4相比，Fibion在测量健康个体的久坐时间和直立时间方面显示出良好到极佳的效度。
