北京与重庆地区成人身高变化的研究

1983年对北京、重庆两地市区和农村汉族685对父子和667对母女的身高和坐高进行了测量。结果表明,两地市区与农村的子女比其父母分别高2.4至4.0厘米(P<0.01)。在28.5年中,一代人平均增高3.35厘米。市区男女两代人都比农村的要高,而且市区年青人身高增加比农村的多。女青年身高增加比男青年的更多。北京人比重庆人高,而且北京年青一代身高增加比重庆人更多。重庆年青人上身增长比下肢多,而北京年青人则下肢增长多。结果还表明,身高相关系数为0.37—0.45,遗传力h2值在0.6665—0.8217之间。

STUDY ON THE CHANGES OF STATURE OF HAN NATIONALITY IN BEIJING AND CHONGQING DISTRICS

A survey was carried out to measure the stature and sitting height of 685 father-son and 667 mother-daughter pairs of Han nationality in Beijing and Chongqing areas. The results indicate that sons daughters are significantly taller than their fathers mothers (increase from 2.3 to 4.0 cm, p<0.01) The average stature increased 3.35 cm during the last 28.5 years. The two generations from urban area are higher than those from countryside. The height in the urban region increases more rapidly than that in the countryside, and that of girls increases more than boys.
