背景：与间接量热法(IC)相比，本研究确定了感觉佩戴臂章(SWA)在久坐和轻便办公室工作时的有效性和敏感性。方法：受试者22名，年龄30~，随机分为仰卧、坐着不动、站立不动、坐着办公、站立办公、以每小时1.0英里的速度行走6种状态，每种状态5分钟。分析了每个活动(即平均4分钟和5分钟)的稳定状态。结果：SWA(1.58kcal/min)和IC(1.64kcal/min)的能量消耗(EE)显著相关，r(20)=0.9，P<0.01；IC=0.90，95%CI(0.699，0.966)。各条件的相关系数r(20)=0.53~0.83，ICC=0.49~0.81，但差异均有统计学意义(P<；0.05)。测量方法和条件之间存在显著的交互作用(P<；.001)。在站立不动、坐着办公和站立办公时，SWA低于预测的EE。结论：久坐和轻活动办公行为的SWA和ICEE显著相关。然而，在办公室工作时(站着或坐着)和站着不动时，SWA可能预测不到EE，这使得它的敏感度略低于IC。
Background: This study determined the validity and sensitivity of the Sense Wear armband (SWA) during sedentary and light office duties compared with indirect calorimetry (IC). Methods: Participants (N = 22), 30 to 64 years of age, randomly performed 6 conditions for 5 minutes each (ie, supine, sitting no movement, standing no movement, sitting office work, standing office work, walking at 1.0 mph). Steady state for each activity (ie, average for minutes 4 and 5) was analyzed. Results: Energy expenditure (EE) for the SWA (1.58 kcal/min) and the IC (1.64 kcal/min) were significantly correlated, r(20) = 0.90, P < .001 and ICC = 0.90, 95% CI (0.699, 0.966). Correlation results for each condition varied in strength, r(20) = 0.53 to 0.83 and ICC = 0.49 to 0.81, but were all significant (P < .05). A significant interaction between measurement method and condition existed (P < .001). The SWA under predicted EE during standing with no movement, sitting office work, and standing office work. Conclusion: The SWA and IC EE rates were strongly correlated during sedentary and light activity office behaviors. However, the SWA may under predict EE during office work (standing or sitting) and when standing motionless, making it slightly less sensitive than IC.
