Automatic roll up measuring tape

Anthropometric evaluations were individually conducted based on the guidelines from the International Society for the Advancement of Kinanthropometry (ISAK). 21 For body measurements, a TANITA® BC-418MA body composition analyzer (West Drayton, UK) was utilized. Height was measured twice using a Seca 214* portable stadiometer, accurate to 5 mm. The average of these two measurements was used for the analysis. The calculation of body mass index (BMI) was done by dividing the weight in kilograms by the square of the height in meters. Waist circumference (WC) was measured by placing a Seca automatic roll-up measuring tape (with a precision of 1 mm) at the midpoint between the lowest rib and the upper edge of the iliac crest, at the conclusion of a normal exhalation. Blood pressure (BP) readings were obtained using a calibrated aneroid sphygmomanometer along with a Littmann® stethoscope (from Saint Paul, MN, USA), following internationally recognized recommendations. 22

We calculated BMI as weight divided by height squared (kg/m 2 ) and we measured WC with a Seca automatic roll-up measuring tape (precision of 1 mm) using the horizontal plane midway between the lowest rib and the upper border of the iliac crest at the end of a normal inspiration/expiration. Hip circumference was measured at the maximum extension of the buttocks as viewed from the right side. WHR and WHtR were consequently calculated by dividing the WC by the hip circumference and the height, respectively. We determined BF% using bioelectrical impedance analyses (BIA) by whole-body impedance (Tanita Model BC-418®, Tokyo, Japan). Detailed information about the BIA technique has been provided in previous studies. 21 (link) The rest anthropometric indexes (AVI, BRI, BAI, BAIp, C-Index, and ABSI) were calculated using the following formulas: AVI = [2Waist Circunference 2 (cm) + 0.7(Waist Circumference -Hip Circumference) 2 (cm)]/ 1000 (Guerrero-Romero et al. 17 ) BRI = 364.2 -365.5 [1 -π -2 Waist Circunference 2 (m) Height -2 (m)] 1/2 (Thomas et al. 10 ) BAI = [Hip circumference (m)/Height 2/3 (m)] -18 (Bergman et al. 14 ) BAIp = Hip circumference (cm)/height (m) 0.8 -38 (El Aarbaoui et al. 15 ) (Valdez 22 ) ABSI = WC (m)/ [BMI 2/3 (kg/m 2 )Height 1/2 (m)] (Krakauer et al. 9 )
