These measurements were conducted at each clinical site according to standardised procedures. BMI was calculated as weight divided by height squared (kg/m2). Waist and hip circumferences were averaged from two repeated measures with a non-stretch tape. Total body fat and its distribution (peripheral fat, VAT, SCAT) and lean mass and its distribution (appendicular lean mass) were estimated with a DEXA scan (Lunar Prodigy Advanced fan beam scanner, GE Healthcare, Bedford, United Kingdom; GE encore software, version 14.10.022 to 16, GE Medical Systems(21 (link))). Specifically, the DEXA system demarcated the boundaries of the android region based on an established protocol. VAT was estimated as part of the android region from an inbuilt algorithm of the DEXA software. SCAT was calculated after subtracting VAT from the android fat mass. These DEXA estimates of abdominal VAT and SCAT have been validated against amounts of VAT and SCAT determined by computed tomography(22 (link)) and magnetic resonance imaging(23 (link)), the reference methods for adipose tissue quantification.
Ge encore software
Manufactured by GE Healthcare
Sourced in United Kingdom
GE Encore software is a comprehensive imaging analysis platform developed by GE Healthcare. It provides tools for visualizing, processing, and analyzing medical images from various modalities, including CT, MRI, and PET scans. The software's core function is to enable healthcare professionals to effectively manage, interpret, and share medical imaging data to support patient care and clinical decision-making.

A DXA scanner (GE Lunar Healthcare Corp, Madison, WI) was used to measure BMC (in grams) for the LS (L1-L4), bilateral proximal femoral neck, and the total body. The total body scan was then used to obtain data for specific regions, such as legs and total body less head. The analyses were performed using GE enCORE software (2006, version 14.10.022; GE Healthcare, Madison, WI). The DXA equipment accuracy was checked on a daily basis before each scanning session, using the LS phantom as recommended by the manufacturer, and the same researcher performed all the scans. The positioning of the participants and the analyses of the results were undertaken according to the International Society for Clinical Densitometry (5) (link). DXA have showed excellent precision for BMC (coefficient of variation = 0.6%) in young athletes (3).

A DXA scanner (GE Lunar Prodigy Healthcare Corp., Madison, WI, USA) was used to measure BMD (g/cm 2 ), BMC (g), bone area (BA, cm 2 ), fat mass (g) and lean mass (g). Four scans were performed to obtain data for the lumbar spine (LS, L1-L4), right and left hip (including femoral neck, Ward's triangle, trochanter and shaft sub-regions; the mean of right and left hip scans was A C C E P T E D used), and the total body scan. The total body scan was then used to obtain data for specific regions such as: arms, legs, pelvis and total body excluding head. All DXA scans and subsequent in-software analyses were completed by the same researcher, using the same DXA scanner and the GE encore software (2006, version 14.10.022). The positioning of the participants and the analyses of the results were undertaken according to International Society of Clinical Densitometry (4) .

A dual energy X-ray absorptiometry (DXA) scanner (GE Lunar Prodigy Healthcare Corp., Madison, WI, USA) was used to measure aBMD (g/cm 2 ), fat mass (g) and lean mass (g) at specific regions of the body. Four scans were performed to obtain data for the lumbar spine (LS, L1-L4), bilateral proximal femora (the mean of both was used for the current analysis) and the total body. The total body scan was then used to obtain data for specific regions such as: arms, legs and total body less head (TBLH). All DXA scans and subsequent in-software analyses were completed by the same researcher, using the same DXA scanner and the GE encore software (2006, version 14.10.022).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
