Abstract
There are significant racial differences in body proportions. Such data are not readily available for Chinese children. This article reports a cross section study of body proportions of 2193 Hong Kong Chinese children, ages 4 to 16 years, with equal gender distribution. Standing height, sitting height, and arm span were measured with standard equipment and methodology. Lower segment height was calculated as the difference between standing height and sitting height. Statistical analysis of the results showed a high linear correlation of the standing height with arm span, sitting height, and lower segment height, with a correlation coefficient ranging from 0.965 to 0.983 for both genders. When expressed as the ratio of standing height to arm span, the value was relatively constant and changed only linearly from 1.03 to 1 in girls and 1.03 to 0.98 in boys ages 4 to 16 years. The ratio of sitting height to lower segment height varied from a mean of 1.4 to 1.14 in boys and 1.36 to 1.18 in girls ages 4 to 16 years. The Chinese children were found to have a proportional limb segmental length relative to the trunk that differed significantly from the proportionally longer limbs in whites and blacks.
