使用连接在手腕上的敏感电子监测仪（Mini-Motionlogger, amburory Monitoring Inc.）记录了65名女性和54名男性在两个24小时内的动态血压（BP）和心率（HR）记录，年龄在55岁至79岁之间，所有人都身体健康。目的是检查在清醒和睡眠期间以及在各种日记定义的行为期间，各种体力活动测量与动态血压和心率之间的关系。在受试者间相关分析中，对于清醒和睡眠时段，活动测量值的平均值和变异性与动态血压和心率测量值的平均值或变异性均不相关。受试者内部分析显示，在清醒或睡眠状态下，活动与血压或心率之间几乎没有显著的共变证据，大多数参与者显示出轻微的正相关。活动量的测量区分了两种行为，一种是体力消耗较少的行为（看电视），另一种是体力消耗较多的行为（走路）。与整体状态（清醒、睡眠）、姿势（站立、坐着）和社会状况（与家人在一起vs与朋友在一起）相关的血压或HR差异中，活动占相对较小的比例。讨论了电子活动监测在自然环境下血压和心率研究中的应用。
A sensitive electronic monitor (Mini-Motionlogger, Ambulatory Monitoring Inc.) attached to the wrist was used to record movements during two 24-hr days of ambulatory blood pressure (BP) and heart rate (HR) recording in 65 women and 54 men between the ages of 55 and 79 years, all of whom were in good health. The objective was to examine the relationship between various measures of physical activity and ambulatory BP and HR during waking and sleeping periods and during various diary-defined behaviors. For waking and sleeping periods, neither the mean nor the variability of the activity measure was associated with the mean or variability of the ambulatory BP and HR measures in between-subjects correlational analyses. Within-subject analyses showed little evidence of significant covariation between activity and BP or HR during either waking or sleeping conditions with most participants showing a slightly positive association. The activity measure discriminated between behaviors associated with little effort (watching television) versus more energetic behaviors (walking). Activity accounted for a relatively small amount of the difference in BP or HR related to overall state (wake, sleep), posture (stand, sit), and social condition (being with family vs. being with friends). The utility of electronic activity monitoring for studies of BP and HR in natural settings is discussed.
