Estimation of Daily Energy Expenditure in Pregnant and Non-Pregnant Women Using a Wrist-Worn Tri-Axial Accelerometer
BACKGROUND Few studies have compared the validity of objective measures of physical activity energy expenditure (PAEE) in pregnant and non-pregnant women. PAEE is commonly estimated with accelerometers attached to the hip or waist, but little is known about the validity and participant acceptability of wrist attachment. The objectives of the current study were to assess the validity of a simple...
متن کاملLab-based validation of different data processing methods for wrist-worn ActiGraph accelerometers in young adults.
The wrist is increasingly being used as the preferred site for objectively assessing physical activity but the relative accuracy of processing methods for wrist data has not been determined. OBJECTIVE This study evaluates the validity of four processing methods for wrist-worn ActiGraph (AG) data against energy expenditure (EE) measured using a portable metabolic analyzer (OM; Oxycon mobile) a...
متن کاملValidity and Comparability of a Wrist-Worn Accelerometer in Children.
BACKGROUND: Wrist-worn accelerometers may provide an alternative to hip-worn monitors for assessing physical activity as they are easier to wear and may thus facilitate long-term recordings. The present study aimed at a) assessing the validity of the Actiwatch (wrist-worn) for estimating energy expenditure b) determine cut-off values for light, moderate and vigorous activities, c) studying the ...
متن کاملCalibration and Validation of a Wrist- and Hip-Worn Actigraph Accelerometer in 4-Year-Old Children
INTRODUCTION To determine time spent at different physical activity intensities, accelerometers need calibration. The aim of this study was to develop and cross-validate intensity thresholds for the Actigraph GT3X+ accelerometer for wrist and hip placement in four-year-old children. METHODS In total 30 children (49 months, SD 3.7) were recruited from five preschools in Stockholm. Equipped wit...
متن کاملNon-Consent to a Wrist-Worn Accelerometer in Older Adults: The Role of Socio-Demographic, Behavioural and Health Factors
BACKGROUND Accelerometers, initially waist-worn but increasingly wrist-worn, are used to assess physical activity free from reporting-bias. However, its acceptability by study participants is unclear. Our objective is to assess factors associated with non-consent to a wrist-mounted accelerometer in older adults. METHODS Data are from 4880 Whitehall II study participants (1328 women, age range...
