Time changes in the body dimensions of male Australian Army personnel between 1977 and 2012

摘要

The aim of this study was to quantify time changes in the body dimensions of male Australian Army personnel. Following a systematic review, two studies were identified and matched for occupation and age (n = 669) with time changes in 12 absolute and 11 proportional body dimensions assessed between 1977 and 2010-12. Changes in means were expressed as absolute, percent and standardised changes, with changes in variability assessed visually and as the ratio of coefficients of variation (CVs). Time changes in absolute dimensions were typically positive (increases) and moderate in magnitude (median standardised change 95%Cl: 0.53 +/- 0.23), and while changes in proportional dimensions were typically negligible (median standardised change +/- 95%Cl: 0.16 +/- 0.33), substantial changes (standardised changes >= 0.2 or <=-0.2) were observed in several dimensions. Variability in body dimensions has also typically increased (median ratio of CVs +/- 95%Cl: 1.10 +/- 0.07) and become more right-skewed. These findings have important implications for the design and acquisition of new military vehicles, body equipment and, clothing. Crown Copyright (C) 2016 Published by Elsevier Ltd.
