汉族人群体部测量表型的相关性

目的：探讨汉族人群体部测量表型间的相关性及其在人群间的差异。方法：对南、北、中部3 个地区汉族 人群的42 项体部测量表型进行Pearson 线性相关分析。结果：汉族人群体部的高度表型之间、高度与长度表型之间、 长度表型之间、围度表型之间具有较强的正相关性，而宽度表型之间、宽度与高度表型之间、宽度与长度表型之间、 宽度与围度表型之间具有中等程度的正相关性，围度与高度、长度表型之间则具有较弱的正相关性。结论：体部 测量表型间的相关性反映了人体部分特征发育的关联性与规律性，同时相关性在人群间存在明显的差异，可为后 期复合表型的遗传学研究提供数据支撑，有助于深入探讨复杂性状的遗传学机制。

Correlation of body anthropometric traits in Han population

Objective To investigate the correlations between human body anthropometric traits in Han ethnic group and the differences of correlations among 3 populations. Methods Pearson linear correlation analysis was carried out for 42 anthropometric traits in southern Han， northern Han and central Han population. Results There was a strong positive correlation between body height traits， height and length traits， length traits， and circumference traits in Han population， a moderate positive correlation between width traits， width and height traits， width and length traits， and width and circumference traits. The circumference traits had a weak positive correlation with height and length traits. Conclusion The correlations between body anthropometric traits reflect the regularity and synchronicity of growth and development of some body traits， and significant differences do exist in the correlations among the 3 populations， which can provide data support for the genetic studies of compound phenotypes in the later stage， and help to explore the genetic mechanism of complex traits in depth.
