This cross-sectional study was designed to characterize by age the ratios of limb segments length to height and extremities-trunk ratio and body proportions of southern Chinese children.
Data were collected from students (n = 4715) from five school, aged 6-17 years, in the city of Chongqing. Their standing height, sitting height, arm span, forearm length, upper arm length, leg length, lower leg length, and ratios of extremities to trunk length were determined.
Sitting height, forearm length, upper arm length, arm span, and lower leg length were highly correlated with standing height (r > 0.9; P < 0.05). The ratio of extremities to trunk increased till about 13 years of age for both genders.
The length of extremities and their ratio to sitting height reflect regular changes of growth in Chinese children as their age, and limb segments length is highly correlated with height.
本横断面研究旨在按年龄对中国南方儿童的肢体节段长度与身高之比、四肢与躯干之比及身体比例进行特征描述。
收集了重庆市五所学校4715名6至17岁学生的数据。测定了他们的站立身高、坐高、臂展、前臂长度、上臂长度、腿长、小腿长度以及四肢与躯干长度之比。
坐高、前臂长度、上臂长度、臂展和小腿长度与站立身高高度相关（r>0.9；P<0.05）。两性的四肢与躯干之比均在约13岁前增加。
四肢长度及其与坐高之比反映了中国儿童随年龄增长的正常生长变化，且肢体节段长度与身高高度相关。
