Bc418ma body composition analyser

Exposures were five adiposity markers; BMI is the ratio of the measured body mass in kg divided by the squared height measured in metres. Height was measured using a Seca 202 height measure. Weight was measured to the nearest 0.1 kg using the Tanita BC-418 MA body composition analyser. The natural indent was measured for the waist circumference (the umbilicus was used if the natural indent could not be observed). The hip circumference was recorded at the widest part of the hips. Waist-to-hip ratio and waist-to-height ratio are the ratios of waist-to-hip circumference and waist circumference to height, respectively. Percentage body fat was measured using the Tanita BC-418 MA body composition analyser (fat mass divided by the total body mass). All exposures were treated as continuous variables. Body mass index of 22 kg m⁻² was the referent value for BMI.⁶ (link) The referent value for the other adiposity measure was the corresponding value of each measure for BMI of 22 kg m⁻² by regressing the BMI on each adiposity measure.

At the baseline assessment centre visit, trained staff used standard procedures to collect and record the body size and composition measurements. Body weight was measured using the Tanita BC-418MA body composition analyser. Participants were asked to remove their shoes and heavy outer clothing before weighing^{9 ,10} . Height was measured in a barefoot standing position using the Saca 202 device. BMI was calculated by dividing weight in kilograms by the square of height in metres. Waist circumference and hip circumference were measured using the Wessex non-stretchable sprung tape measurement. Waist-to-hip ratio was calculated by dividing waist circumference by hip circumference. The Tanita BC-418MA body composition analyzer (Tanita, Tokyo, Japan) was used to assess bioelectrical impedance measures including total body fat percentage, and trunk fat percentage.

Body mass index was calculated as weight divided by height squared (kg/m²). Standing height (cm) was measured by a Seca 202 device (SECA). Body fat percentage was estimated by bioelectrical impedance, with measures ranging from 1% to 75% in 0.1% increments. Weight and bioimpedance were measured by the Tanita BC-418MA body composition analyser (Tanita Corporation of America). Finally, waist circumference was manually measured in centimetres.
