准确评估儿童(5-12岁)的自由生活体力活动能量消耗(PAEE)是至关重要的
英文摘要
Accurate assessment of children’s (5-12yrs) free-living physical activity energy expenditure (PAEE) is critical to understanding the complex and interdependent relationship between children’s PAEE and health outcomes. The combination of movement (e.g., steps, counts, raw signal) and heart rate data provides reasonably accurate estimates of children’s PAEE during lab conditions. However, the combination of movement and heart rate (MOVE+HR) may be inadequate for predicting children’s free-living PAEE. Studies in adults demonstrate including the type of activity (e.g., the participant is walking, running, cycling, etc.) improves estimates of free- living PAEE, relative to using movement or MOVE+HR. Yet, this evidence is based on studies conducted in adults. No studies of children have investigated the impact of adding activity type to PAEE prediction equations that use MOVE+HR. Existing consumer wearables (e.g., Fitbit, Garmin) are promising for the assessment of children’s free-living PAEE. These devices incorporate built-in pattern-recognition features that automatically detect activity type, and these metrics are provided in a user-friendly format for the end-user; however, no known studies have evaluated the ability of consumer wearables to autodetect activities in children. Consumer wearables also use photoplethysmography to capture HR and accelerometry to capture movement. Their unique ability to capture activity type, HR, and movement metrics could significantly improve estimates of free-living PAEE in children. Aim 1 will evaluate the impact of including activity type, captured via direct observation, to regression equations that use movement and HR data from consumer wearables (i.e., Garmin Vivoactive 4S and Fitbit Sense). Aim 2 will evaluate the ability of consumer wearables (i.e., Garmin Vivoactive 4S and Fitbit Sense) to automatically detect activities (i.e., walking, running, biking). To accomplish these aims, this study will capitalize on the validation design (i.e., semi-structured physical activity protocol and data management/extraction procedures) and draw on data collected from 120 children (5-12yrs) from an existing R01 project. This project will use analytical techniques, including cross-sectional time series (CSTS), multivariate adaptive regression spline (MARS), machine learning, and equivalence testing to address the following aims. The project’s long-term goal is to advance the assessment of children’s PAEE in epidemiologic- and intervention- based studies for children, which is critical to understanding the complex relationship between children’s PAEE and health outcomes. Through the execution of this project, the following will be gained: an in-depth knowledge of the literature related to assessment of PAEE in children, expertise designing and implementing validation studies assessing PAEE in children, hands-on training using gold standard measures to assess children’s PAEE and activity type, proficiency performing advanced analytical techniques, and scientific communication and grantsmanship skills, including peer-reviewed publication, scientific presentation, mentored manuscript review, and a drafted post-doctoral grant application.
