The interday reliability of the Intelligent Device for Energy Expenditure and Activity (IDEEA) has not been studied to date. The study purpose was to examine the interday variability and reliability on two consecutive days collected with the IDEEA, as well as to predict the number of days needed to provide a reliable estimate of several movement (walking and climbing stairs) and nonmovement (lying, reclining, and sitting) behaviors and standing in older adults. The sample included 126 older adults (74 women) who wore the IDEEA for 48 hr. Results showed low variability between the 2 days, and the reliability was from moderate (intraclass coefficient correlation = .34) to high (.80) in most of movement and nonmovement behaviors analyzed. The Bland-Altman plots showed high-moderate agreement between days, and the Spearman-Brown formula estimated that 1.2 and 9.1 days of monitoring with the IDEEA are needed to achieve intraclass coefficient correlations ≥ .70 in older adults for sitting and climbing stairs, respectively.
迄今为止，尚未对能量消耗与活动智能设备（IDEEA）的日间可靠性进行研究。本研究的目的是检测连续两天使用IDEEA收集数据的日间变异性和可靠性，以及预测为可靠估计老年人的几种运动（行走和爬楼梯）和非运动（躺、斜倚和坐）行为及站立所需的天数。样本包括126名老年人（74名女性），他们佩戴IDEEA达48小时。结果显示，两天之间的变异性较低，在分析的大多数运动和非运动行为中，可靠性从中度（组内相关系数=0.34）到高度（0.80）。Bland-Altman图显示两天之间具有中高度一致性，Spearman-Brown公式估计，在老年人中，分别需要1.2天和9.1天的IDEEA监测，才能使坐和爬楼梯的组内相关系数≥0.70。
