Determination of Stature from Upper Arm Length in Medical Students

introduction: in order to make a dimensional proportion between human and equipment orenvironment, anthropometric data bank is essential. anthropometry has an important role inindustrial management and ergonomic design. this information is needed to be collected regularlyin every society. the purpose of this study was to determine arm length to height ratio according togender in adults, between ages 19-21 in students of medical sciences, tehran. methods: this cross-sectional investigation was performed on 100 students (50 males and 50females) from tehran university of medical sciences (aged 19-21 years). participants wereselected randomly and they didn’t have any physical deformities or any previous history oftrauma. standing height (stature) and upper arm length (ual) were measured for each subject.measurements were performed in standard position. results: the mean age of cases was 21±1.32 years. mean age of male cases was 20±1.2 yearsand female cases was 21±1.81 years and there wasn’t significant difference in the age of sexgroups (p=0.219). a significant differences were observed in the height between the two sexes(p=0.0001, and table 1). also, there was a significant difference in the upper arm length of sexgroups (p=0.0001). in addition, there was a correlation between height and upper arm length ofcases (r =0.716, p=0.0001). conclusion: according to the results, ual can be a reliable factor for predicting the stature iniranian medical students.
