Abstract

BACKGROUND

Standing height (SH) is the most reliable parameter used to predict spirometric values in children, but measurement of this parameter may be difficult in children with thoracic or spinal abnormalities. This study was designed to establish reference equations to estimate SHs of children using their arm span length (ASL) or forearm ulnar length (UL) as an index.

METHODS

Children aged 1-17 years were enrolled to measure their SH, body weight, ASL, and UL. Sex and age were also recorded. The relationship between SH and children's weight, age, ASL, and UL were analyzed. Regression equations using different indexes for SH of enrolled cases were used, and adults aged 18-64 years were also enrolled for comparison.

RESULTS

A total of 512 children and 144 adults were enrolled. There was a strong linear relationship between SH and both ASL and UL in children and adults. Pearson's correlation coefficients of SH for ASL and UL were 0.989 and 0.968 (p < 0.001) in children and 0.933 and 0.845 (p < 0.001) in adults. The linear regression equations for estimating SH in children were calculated as SH = 9.363 + 0.943 ASL (r = 0.978, p < 0.001) and SH = 14.542 + 5.570 UL (r = 0.936, p < 0.001). In adults, age and sex were also added as indexes: SH = 59.849 + 0.642 ASL-0.047 Age +3.431 Sex (male = 1; female = 0) (r = 0.887, p < 0.001) and SH = 102.824 + 2.317 UL -0.049 age + 6.739 sex (r = 0.773, p < 0.001).

CONCLUSION

Both ASL and UL have a significant linear relationship with SHs of children and adults. True SH can be estimated using regression equations with ASL or UL as a single index for situations where direct measurement of SH is difficult.

摘要

背景

身高是预测儿童肺功能指标最可靠的参数，但对于存在胸廓或脊柱畸形的儿童，身高的测量可能较为困难。本研究旨在建立使用臂展长度（ASL）或前臂尺骨长度（UL）作为指标预测儿童身高的参考方程。

方法

招募 1-17 岁儿童，测量其身高、体重、臂展长度和前臂尺骨长度，并记录性别和年龄。分析身高与儿童体重、年龄、臂展长度和前臂尺骨长度的关系。使用不同指标回归方程预测纳入病例的身高，并招募 18-64 岁成年人进行比较。

结果

共纳入 512 名儿童和 144 名成年人。儿童和成年人的身高与臂展长度和前臂尺骨长度均呈强线性关系。儿童的 Pearson 相关系数为 0.989 和 0.968（p<0.001），成年人的 Pearson 相关系数为 0.933 和 0.845（p<0.001）。儿童身高的线性回归方程为 SH=9.363+0.943 ASL（r=0.978，p<0.001）和 SH=14.542+5.570 UL（r=0.936，p<0.001）。成年人中，还加入了年龄和性别作为指标：SH=59.849+0.642 ASL-0.047 年龄+3.431 性别（男=1；女=0）（r=0.887，p<0.001）和 SH=102.824+2.317 UL-0.049 年龄+6.739 性别（r=0.773，p<0.001）。
