869 scale

Manufactured by Seca
Sourced in Germany

The 869 scale is a precision weighing instrument designed for laboratory use. It features high accuracy and reliability, with the ability to measure weights within a specific range. The core function of the 869 scale is to provide precise and consistent measurements for various applications within a laboratory setting.

Adolescent Anthropomorphic Measurements

Check if the same lab product or an alternative is used in the 5 most similar protocols
Adolescents’ anthropomorphic data was collected by trained research assistants. Weight was measured twice with a Seca 869 scale, with 1–9 days between weight assessments; height was measured with a Seca 213 mobile stadiometer. Participants were weighed with their clothes on and their shoes off. Body mass index (BMI) was calculated EpiInfo version 3.5.1. As the recommended obesity outcome measure for pediatric samples, percent overweight was calculated as the percent each adolescent’s BMI was over their CDC-defined median BMI for age and sex.

Anthropometric Measurements for Health Assessment

The weight (kg) was measured using a SECA scale (869 scale, Hamburg, Germany; accuracy 0.05 g) and the height (cm) was measured using a stadiometer (SECA model 213, accuracy 0.10 cm). The body mass index (BMI) was calculated as the weight (kg) divided by the height squared (m 2 ). The waist circumference (WC) (cm) was measured at the level of the umbilicus zone in the horizontal plane with a non-elastic tape (SECA model 200) . The waist-to-height ratio (WHtR) (cm/m) was calculated as the WC expressed in centimetres divided by the height expressed in metres. All measurements were taken twice, and the mean was used in the analyses.

Measuring Pediatric Obesity Intervention Outcomes

Check if the same lab product or an alternative is used in the 5 most similar protocols
Percent overweight was calculated as the percentage their BMI was above the CDC’s median BMI for age and gender. This is the recommended primary outcome measure for pediatric obesity, especially with samples of obese adolescents for whom zBMI and BMI are not considered optimal measures (Epstein et al., 1994 (link); Paluch et al., 2007 (link)), and the measure has been shown to respond to intervention in other studies with this population (Ellis et al., 2010; MacDonell et al., 2010 (link); Naar-King et al, 2009 (link)). BMI was computed using Epi Info software version 3.5.1 (CDC, Atlanta, GA). Weight was assessed with the Seca 869 scale (Seca, Hanover, MD) at T1, T2, and T3. Youth were weighed twice for each data collection point, between 1 and 9 days apart (M=4.42, SD=2.10) with the average weight used to calculate BMI, and height was assessed using the Seca 213 Stadiometer.

Eating Patterns and BMI Assessment

All aspects of the study were approved by Wayne State University’s Institutional Review Board. The trial was registered with ClinicalTrials.gov (identifier: NCT01350531). Data was collected in the home to reduce participant burden. At the baseline assessment, participants completed self-administered measures regarding eating pathology (e.g., binge eating, addictive-like eating) and patterns of dietary intake (e.g., frequency of food consumption). Weight was assessed with the Seca 869 scale (Seca, Hanover, MD), and height was assessed with the Seca 213 Stadiometer. Youth were weighed twice for each data collection point, between 1 and 8 days apart (M=4.18, SD=2.03), with the average weight used to calculate BMI. BMI and BMI percentile were computed using Epi Info software version 3.5.1 (Centers for Disease Control and Prevention (CDC), 2016 ) and then percent overweight was computed based on the CDC-defined median BMI for age and sex.

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.
