项目摘要
Project Summary/Abstract
Accurate measurement of human behavior using devices could significantly advance current knowledge on the
dose-response relationships between chronic diseases and behaviors such as physical activity, sedentary
behavior, and sleep. The primary objective of this proposal is to develop valid approaches to measure 24-hour
physical behavior, as well as to demonstrate a procedure via which those approaches can be compared to
others. We aim to help the research community to converge on methods that use devices to accurately
measure physical activity type and intensity, sedentary behavior and posture, and sleep in adults. Many
promising methods have been proposed to measure behavior from activity monitors. Unfortunately, these
methods – which are now being proposed in large numbers – are typically validated on small amounts of data.
Thus, they may perform well on lab data, but fail when used in the field on large-scale epidemiological or
intervention studies. Moreover, the performance of different methods is rarely compared head-to-head,
creating uncertainty for public health researchers about which are the best to use. Quantifying the relative
performance of methods that produce similar outcome measures but use different devices or on-body device
locations is even more unusual. We will make it easy for researchers interested in physical activity
measurement to meaningfully compare performance between new methods and confidently apply those
methods to both large-scale surveillance studies and longitudinal interventions. The project has four specific
aims: (1) Collect well-annotated data of physical activity, sedentary behavior, and sleep, (2) Use the data from
Aim 1 to develop and validate approaches that yield 24-hour estimates of free-living physical activity (type,
intensity), sedentary behavior (type, posture), and sleep (wake/sleep, stages), (3) Develop and incrementally
refine a suite of tools that researchers can use to easily deploy advanced approaches to measure physical
activity, sedentary behavior, and sleep, even for large data, and (4) Use the data and new approaches (Aims 1
and 3) to host four competitions evaluating models, where all entries submitted by other researchers, will be
directly compared, ranked, and improved. The goal is to help researchers converge on “gold standard” methods
to robustly measure physical activity using common monitor configurations, as well as those devices and
configurations likely to be used soon.

使用设备对人类行为进行准确的测量可以显着提高当前知识
慢性疾病和行为(例如体育锻炼,久坐)之间的剂量反应关系
行为和睡眠。该提案的主要目的是开发有效的方法来测量24小时
身体行为,以及可以将这些方法与这些方法进行比较的程序
其他的。我们旨在帮助研究社区融合使用设备准确的方法
测量体育活动类型和强度,久坐的行为和姿势,以及成人的睡眠。许多
已经提出了有希望的方法来衡量活动监测器的行为。不幸的是,这些
现在大量提出的方法通常在少量数据上进行验证。
那就可以在实验室数据上表现良好,但是在大规模流行病学或

3)主持四个评估模型的比赛,其他研究人员提交的所有条目将是
直接比较,排名和改进。目的是帮助研究人员汇总“黄金标准”方法
使用常见监视器配置以及这些设备和
配置可能很快就会使用。
