我们使用双标记水（DLW）结合间接量热法作为标准测量，比较了45至84岁女性（n = 35）和男性（n = 32）的两种身体活动回忆问卷和运动检测器的准确性。受试者接受了耶鲁大学身体活动调查（YPAS）和明尼苏达州休闲时间身体活动问卷（LTA）。通过使用Caltrac单轴加速度计和DLW结合间接量热法测定10天内的身体活动能量消耗。在老年女性中，明尼苏达州LTA（386 ± 228千卡/天）和Caltrac（379 ± 162千卡/天）与DLW（873 ± 244千卡/天）相比低估了75%的体力活动。在老年女性中，通过YPAS测量的每日体力活动（863 ± 447 kcal/天）和DLW之间没有观察到差异。在老年男性中，明尼苏达州LTA（459 ± 288千卡/天）和Caltrac（554 ± 242千卡/天）与DLW（1，211 ± 429千卡/天）相比，低估了每日体力活动的50 - 60%。在老年男性中，YPAS测量的身体活动（1，107 ± 612千卡/天）和DLW之间没有差异。尽管女性和男性的YPAS和DLW之间的平均体力活动水平没有差异，但Bland和Altman（Lancet 1：307 - 310，1986）分析表明DLW和YPAS之间的一致性较差（即，一致性限度= − 1，310 - 1，518千卡/天）。我们的数据表明，明尼苏达LTA回忆和Caltrac单轴加速计可能会显着低估老年女性和男性的自由生活日常体力活动能量消耗。虽然YPAS在组的基础上与DLW相比更有利，但其作为个人日常体力活动能量消耗的替代指标在老年女性和男性中可能受到限制。
We compared the accuracy of two physical activity recall questionnaires and a motion detector in 45- to 84-yr-old women (n= 35) and men (n= 32), using doubly labeled water (DLW) in conjunction with indirect calorimetry as the criterion measure. Subjects were administered the Yale Physical Activity Survey (YPAS) and Minnesota Leisure Time Physical Activity Questionnaire (LTA). Physical activity energy expenditure was determined over a 10-day period by using a Caltrac uniaxial accelerometer and DLW in conjunction with indirect calorimetry. In older women, Minnesota LTA (386 ± 228 kcal/day) and Caltrac (379 ± 162 kcal/day) underestimated physical activity by ∼55% compared with DLW (873 ± 244 kcal/day). No difference was observed between daily physical activity measured by the YPAS (863 ± 447 kcal/day) and DLW in older women. In older men, Minnesota LTA (459 ± 288 kcal/day) and Caltrac (554 ± 242 kcal/day) underestimated daily physical activity by ∼50–60% compared with DLW (1,211 ± 429 kcal/day). No difference was found between physical activity measured by the YPAS (1,107 ± 612 kcal/day) and DLW in older men. Despite no difference in mean physical activity levels between YPAS and DLW in women and men, Bland and Altman (Lancet1: 307–310, 1986) analyses demonstrated poor concordance between DLW and YPAS (i.e., limits of agreement = −1,310–1,518 kcal/day). Our data suggest that the Minnesota LTA recall and Caltrac uniaxial accelerometer may significantly underestimate free-living daily physical activity energy expenditure in older women and men. Although the YPAS compares favorably with DLW on a group basis, its use as a proxy measure of individual daily physical activity energy expenditure may be limited in older women and men.
