概括

像Fitbit这样的消费者可穿戴设备与测量青少年身体活动 (PA) 的研究级设备显示了适度的一致性. 然而,分类和数据聚合的差异影响了对公共卫生研究至关重要的准确性.

科学领域:

运动学运动学
公共卫生公共卫生
生物医学工程生物医学工程

背景情况:

消费者可穿戴设备越来越多地用于体力活动 (PA) 干预.
他们的有效性在低PA群体,如青少年女孩,仍然不清楚.
准确的PA测量对于有效的健康干预至关重要.

研究的目的:

评估来自Fitbit Inspire HR和ActiGraph GT3X+的PA测量之间的分钟和日级协议.
在参与干预的拉丁裔青少年中评估设备有效性.
了解不同的切割点和聚合时代如何影响PA数据.

主要方法:

137名青少年女孩同时使用了Fitbit Inspire HR和ActiGraph GT3X+设备.
使用两个切割点 (Freedson和Treuth) 分析了ActiGraph数据.
使用混矩阵评估分钟级协议,使用布兰德-阿尔特曼分析评估日级协议.

主要成果:

ActiGraph的切割点显示,对分钟级的中度-强度PA (MVPA) 分类有适度的共识.
惠比表示公平的协议,主要是由于非MVPA的观察.
与Treuth和Fitbit相比,Freedson切割点高估了每天的MVPA;Treuth和Fitbit的每日比较没有显著差异.

结论:

在PA测量切点之间存在系统差异,需要进一步调查.
菲特比特与ActiGraph表现出适度的一致性,但一致性受到异种性和时代聚合的影响.
了解这些特定于设备的差异对于准确的PA研究和青少年公共卫生促进至关重要.

Holter Monitor: 24-Hour Monitoring

Holter Monitor: 24-Hour Monitoring

Holter monitoring is a continuous electrocardiography (ECG) recording that tracks the heart's electrical activity over an extended period, generally 24 to 48 hours. This noninvasive diagnostic tool detects irregular heart rhythms that may not be captured during a standard ECG performed in a clinical setting.DeviceThe Holter monitor is a portable, small device connected to several electrodes on the patient's chest. These electrodes detect the heart's electrical signals and transmit them to the...
