Abstract
The anthropometric dimensions of three major ethnic groups in Singapore were studied on 94 female VDU operators. The postural preferences at the VDU work stations were also investigated. Few anthropometric differences were noted for the Chinese, Malays arid Indians. However, when compared to data from Germany and the U.S.A., the three Asian cohorts are smaller in body size. Owing to the smaller body build, the Singapore operators preferred to have a sitting height of about 46 cm, and a working height of about 74 cm, compared with the 47 cm and 77 cm, respectively, preferred by European operators. Despite the anthropometric differences, the Singapore VDU operators, like their counterparts in Europe and the U.S.A. also preferred to sit in a pronounced backward leaning posture with a slightly open elbow angle. This sitting posture seems to ignore the traditional recommended upright trunk position of 90°.
