The Prevalence of Childhood Obesity Depends on Which Body Composition and Anthropometric Measurement and Cutoff Were Used
Peer reviewed Peer reviewed

Huaijin Xu; Weimo Zhu; Xiong Qin; Zezhao Chen; Xiaotian Gao – Measurement in Physical Education and Exercise Science, 2024
Using the 2017-2018 National Health and Nutrition Examination Survey (weighted population size = 35,460,209; 8-18 years old; 52.1% males), we compared the obesity prevalence in children and adolescents between body mass index-based (BMI-based) and total percent body fat-based (BF%-based, measured by the dual-energy x-ray absorptiometry) cutoffs.…

The Associations between Body Mass Index, Estimated Lean Body Mass, and Urinary Hydration Markers at the Population Level
Peer reviewed Peer reviewed
Direct linkDirect link
Ehlert, Alex M.; Wilson, Patrick B. – Measurement in Physical Education and Exercise Science, 2021
Obesity has been found to relate to urine-assessed hypohydration risk at the population level, but studies have often failed to account for lean mass, which influences urine solute load. Adults (n = 8,699) from the National Health and Nutrition Examination Survey were categorized as hypohydrated or not using five urine-based methods. Hypohydration…

The Validity of Relative Fat Mass and Body Adiposity Index as Measures of Body Composition in Healthy Adults
Peer reviewed Peer reviewed

Fedewa, Michael V.; Nickerson, Brett S.; Esco, Michael R. – Measurement in Physical Education and Exercise Science, 2020
Higher relative adiposity is independently associated with adverse health consequences. As such, accurate estimates of body composition in field settings are of utmost importance. The aim of this study was to examine the validity of the Body Adiposity Index (BAI) and Relative Fat Mass (RFM) as measures of total body adiposity. BAI and RFM were…

The Performance of an Algorithm for Classifying Gym-Based Tasks across Individuals with Different Body Mass Index
Peer reviewed Peer reviewed

Gerrard-Longworth, Simon; Preece, Stephen J.; Clarke-Cornwell, Alexandra M.; Goulermas, Yannis – Measurement in Physical Education and Exercise Science, 2020
Previous activity classification studies have typically been performed on normal weight individuals. Therefore, it is unclear whether a generic classification algorithm could be developed that would perform consistently across individuals who fall within different BMI categories. Acceleration data were collected from the hip and ankle joints of 50…

Handgrip Strength Cut-Points for Cardiometabolic Risk Identification in U.S. Younger Population
Peer reviewed Peer reviewed
Direct linkDirect link
DeHondt, Benjamin G.; Madi, Samar A.; Drignei, Dorin; Buchan, Duncan S.; Brown, Elise C. – Measurement in Physical Education and Exercise Science, 2023
Identification of cardiometabolic risk (CMR) in U.S. younger population by assessing muscular strength via handgrip (HG) dynamometry may aid in prevention efforts. Currently, no nationally representative HG cut-points are available for identifying increased CMR in U.S. adolescents or young adults. In this study, we propose normalized grip strength…

Comparison of Body Composition Estimates among Norland Elite®, Lunar Idxa®, and the Bodpod® in Overweight to Obese Adults
Peer reviewed Peer reviewed
Direct linkDirect link
Mason, Jalyn; Morris, Christopher; Long, Douglas E.; Sanden, Madison N.; Flack, Kyle – Measurement in Physical Education and Exercise Science, 2020
Accurate body composition assessment, which includes fat mass (adipose tissue mass, FM), fat-free mass (FFM), and percent fat mass (%FM) is needed to evaluate health and treatment efficacy. The current study compared body composition estimates obtained from the Norland Elite® DXA, BodPod®, and iDXA® before and after a 12-week exercise intervention…

Classification of Obesity Varies between Body Mass Index and Direct Measures of Body Fat in Boys and Girls of Asian and European Ancestry
Peer reviewed Peer reviewed
Direct linkDirect link
McConnell-Nzunga, J.; Naylor, P. J.; Macdonald, H.; Rhodes, R. E.; Hofer, S. M.; McKay, H. – Measurement in Physical Education and Exercise Science, 2018
Body mass index is a common proxy for proportion of body fat. However, body mass index may not classify youth similarly across ages and ethnicities. We used sex- and ethnic-specific receiver operating characteristic curves to determine how obesity classifications compared between body mass index and dual energy x-ray absorptiometry-based body fat…

Cross-Validation of a Recently Published Equation Predicting Energy Expenditure to Run or Walk a Mile in Normal-Weight and Overweight Adults
Peer reviewed Peer reviewed
Direct linkDirect link
Morris, Cody E.; Owens, Scott G.; Waddell, Dwight E.; Bass, Martha A.; Bentley, John P.; Loftin, Mark – Measurement in Physical Education and Exercise Science, 2014
An equation published by Loftin, Waddell, Robinson, and Owens (2010) was cross-validated using ten normal-weight walkers, ten overweight walkers, and ten distance runners. Energy expenditure was measured at preferred walking (normal-weight walker and overweight walkers) or running pace (distance runners) for 5 min and corrected to a mile. Energy…
