Utilizing Buttock Measurements for Estimating Body Weight: Exploring Buttock Width and Popliteal Length for Ergonomic Design

Abstract

This study explores the potential of utilizing buttock measurements, specifically buttock width and bottom popliteal length, as reliable indicators for estimating human body weight. Recognizing the increasing demand for accurate and accessible methods in various fields, author delves into the relationships between these lower body dimensions and overall body mass. The research evaluated 700 young adults, evenly split between 350 males and 350 females, utilizing random snowball sampling techniques from four local governments (Abeokuta South, Abeokuta North, Odeda and Ewekoro) areas of Ogun State, South Western Nigeria with participants aged between 19 and 27years The research centered on assessing human body weight (HBW), buttock width (BW), and bottom popliteal length (BPL) with all measurements documented in centimeters. Data analysis involved utilizing Statistical Package for Social Sciences software version 21.0, for computation of average mean values, standard deviation, coefficient of determination (r2), correlation coefficient (r), and standard error of estimates (SEE). Additionally, linear regression analysis was employed to formulate the model equation for determining HBW, in relation to BW, and BPL. The study provides an accuracy and applicability of anthropometric prediction of HBW and foundation for the development of practical methods with diverse applications, ranging from healthcare assessments to ergonomic design.
