Waist circumference (WC) was assessed to the closest cm, in the standing position in the middle area of the iliac crest and the last palatable rib, using a flexible measuring tape (Seca, Hamburg, Germany). Stature was measured to the closest cm with the help of a standard stadiometer (seca 274, Seca GmbH & Co., KG, Hamburg, Germany). Patients’ weight was measured to the closest 0.1 kg using the seca mBCA 515 device (Seca, Hamburg, Germany). Body composition was evaluated using segmental multi-frequency bioelectrical impedance analysis (BIA) (seca mBCA 515, Seca, Hamburg, Germany). The validity of the BIA unit for body composition determination has been previously reported [52 (link)].
Flexible measuring tape
Manufactured by Seca
Sourced in United States
The Flexible Measuring Tape is a lightweight, portable tool used to measure circumference, length, or distance. It features a flexible, non-stretchable tape made of durable material, marked with standard measurement units. The tape can be easily wrapped around objects or extended to take accurate measurements.

All participants underwent anthropometric measurements while being barefoot and wearing only light clothes. Body weight and height of the participants were measured to the nearest 0.1 kg and 0.1 cm, respectively, by using a balance beam scale (Seca) and a portable stadiometer. The participants were grouped into three categories: normal weight, overweight, and obese, using the cut-off points of body mass index (BMI) by age and sex for children and adolescents proposed by the International Obesity Task Force (IOTF).21 (link)
Waist circumference (WC) was measured to the nearest 0.5 cm by using a flexible measuring tape (Seca) at a level midway between the lower rib margin and the iliac crest. Using the cut-off values of the percentiles of the WC according to the criteria of the National Health and Nutrition Examination Survey III,22 (link) the participants were grouped into the categories on the basis of their WC: below the 75th percentile (normal waist value), 75th<90th percentile and ≥90th percentile. High waist value was defined as WC ≥75th percentile.
Both BP and anthropometric measurements were performed at the subjects’ schools by the same team of trained research personnel (physicians and research assistants).

Anthropometric measurements were administered in standard clothing, recorded in duplicate, and averaged for analysis. If the first two measures differed by >0.1 kilograms (kg) for weight, >0.5 cm for height or circumference measurements, or >1 mm for skinfold thicknesses, then a third measurement was collected, and the closest two measures averaged. Height was measured to the nearest 0.1 cm with a portable stadiometer (Seca, Chino, CA, USA) and weight to the nearest 0.1 kg with a digital scale (Tanita Corporation of America, Arlington Heights, IL, USA). Averages of height and weight were used to calculate BMI. WHO child growth references were used to calculate BMI-for-age Z-scores (25 (link)) (used to describe the sample, but not in prediction models). Skinfold thicknesses were measured to the nearest 1 mm using Lange calipers (Beta Technology Inc., Houston, TX, USA). Body circumferences were measured to the nearest 0.1 cm with flexible measuring tapes (Seca, Chino, CA, USA) (26 ,27 ).

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.
