Dataset for the Criterion Validation of Four Activity Sensors against Doubly Labelled Water for Assessing Habitual 24-Hour Energy Expenditure

Abstract

This dataset contains data from a study evaluating the criterion validity of four activity sensors for assessing habitual 24-hour energy expenditure (EE) against doubly labelled water (DLW), used as the reference method. The dataset includes measurements of habitual energy expenditure obtained using DLW and estimates derived from four activity sensors, together with relevant participant characteristics and study-related variables. The data were collected to enable the comparison of sensor-derived estimates with DLW-based measurements of habitual 24-hour energy expenditure and to support analyses of agreement, validity, and measurement error across the four devices.
