进行了一项横断面研究，以找出是否有任何特定的相关性之间存在身高，腿长和臂宽在成长中的韩国儿童。对10,322名健康儿童（男4740名，女5582名）的身高、腿长和臂展进行了测量。计算了第3、25、50、75和97次摔跤的腿长与身高、腿长与臂展和臂展与身高的比值。结果发现，同年龄组中高个子儿童的腿长与身高、腿长与臂宽、臂宽与身高的比值均大于矮个子儿童。在同一百分位数上，年龄较大的儿童的上述比值均大于年龄较小的儿童，表明腿长和臂宽的增长率一般大于身高的增长率。然而，在青春期开始之前，矮个子儿童的腿长增长比高个子儿童快，之后高个子儿童的腿长增长比矮个子儿童快。腿长的第一次也是最快的增长是从出生到2岁，第二次增长高峰是在青春期。在10至15岁之间，身高较高的儿童的腿长也有异常增长。青春期后，最高的男孩的臂展增长速度比身高快，直到17岁，高个子儿童的臂展比身高长，而最矮的儿童的臂展从未超过身高。
A cross-sectional study was performed to find out if any specific correlations exist among height, leg length and arm span in growing Korean children. Height, leg length and arm span were measured in 10,322 healthy children (4740 males and 5582 females). Computed ratios of leg length to height, leg length to arm span and arm span to height for the 3rd, 25th, 50th, 75th and 97th percentiles were made. It was found that the ratios of leg length to height, leg length to arm span, and arm span to height were bigger in taller children in the same age group than the shorter ones in both sexes. All the ratios were bigger in older children in the same percentile than the younger ones in both sexes, showing that the growth rates of leg length and arm span were bigger than that of height in general. However, growth of leg length is faster in shorter children than in taller children until the onset of puberty, after which growth of leg length in taller children is faster than in shorter children. The first and most rapid growth of leg length is seen from birth to 2 years, the second growth spurt is seen during the pubertal period. An exceptional increment in leg length between ages from 10 to 15 is also noted in taller children. After puberty, arm span grows faster than height until 17 years of age in the tallest male child, and taller children have longer arm span than height, while arm span in the shortest children never exceeds height.
