Inbody370 impedance body composition analyzer

Body mass index (BMI) was calculated based on weight/height during the medical history. Percent Body Fat (PBF) was assessed using an InBody370 Impedance Body Composition Analyzer (InBody Co., Ltd., South Korea). This device uses 15 impedance measurements (3 frequencies: 5 kHz, 50 kHz, 250 kHz; five body segments: right arm, left arm, trunk, right leg, left leg) to produce highly accurate composition estimates and has been found to have a high correlation of 0.99 to dual-energy X-ray absorptiometry (DEXA) for lean body mass in a population of normal-weight adults [31 (link)]. Waist-to-hip ratio (WHR) was calculated with waist and height measurements.

Percent body fat was measured using an InBody370 Impedance Body Composition
Analyzer (InBody Co., Ltd.). This device uses 15 impedance measurements (3 frequencies: 5
kHz, 50 kHz, 250 kHz; five body segments: right arm, left arm, trunk, right leg, left leg)
to produce highly accurate composition estimates and has been found to have a high
correlation of 0.99 to dual-energy X-ray absorptiometry (DEXA) for lean body mass in a
population of normal weight adults. Body mass index (BMI) was calculated using the
following formula based on weight and height obtained during medical history of the
participants: BMI = weight (kg)/height (m)².

Participants underwent an intensive assessment for demographic, anthropomorphic, clinical and psychiatric features, with a main focus on mood, anxiety, trauma, drug use, personality, social and physical function, disability, sleep, fatigue, pain, impulsivity and eating dimensions. From this assessment, we used 120 direct and derived variables. The list of these 120 variables is provided in supplemental Table S2 with details.
Anthropometric body composition variables were assessed using an InBody370 Impedance Body Composition Analyzer (InBody Co., Ltd., South Korea). This device uses 15 impedance measurements (3 frequencies: 5 kHz, 50 kHz, 250 kHz; five body segments: right arm, left arm, trunk, right leg, left leg) to produce highly accurate composition estimates.
Resting state functional magnetic resonance imaging (rsfMRI, parameters: TR = 2000ms, TE = 27 ms, FOV = 240 mm × 240 mm, 2.9 mm slice thickness, 128 × 128 matrix, 39 axial slices, and 240 repetitions) was performed using two identical GE Discovery MR750 3 T scanners while subjects fixated on a cross with eyes open and instructions not to think of anything in particular.
