Abstract and keywords

Previous research has shown that differences in a vehicle occupant’s body morphomics (dimensions and composition) predict the type and severity of injuries that occupant sustains in a motor vehicle crash. Data also suggests that the more an occupant varies from standard test surrogates (crash dummies), the greater the crash injury risk. Current test surrogates were developed based on an American population, but the size and stature of the general population varies substantially world-wide. In the currentstudy, our objective was to determine how Asian population morphomics differ from those of an American population. We analysed CT scans from 1,459 live Taiwanese subjects who underwent CT scanning of the chest, abdomen, and pelvis for trauma. Highly automated software was used to precisely measure body dimension and composition in an anatomically indexed manner. Finalised results were compared between the Asian (n=1,459) and US (n=6,479) adult populations. Our detailed morphomic analysis found that Asians differ substantially in many measures of body dimensions and composition from Americans. Since many morphomic measures affect the type and risk of crash injury in motor vehicle crashes, human body finite element models meant to represent specific population segments will be informed by the results of thisstudy.
