22省市汉族女青少年生长发育状况的分析

利用SPSS计算机软件的PCA-Q分析程序,从分析7项生长发育指标的相似与相异点入手,对我国22个省市区的44个汉族城乡女青少年样本进行聚类分析。分析结果表明,各地区女青少年在生长发育状况上存在着显著差异,这些差异与地理因素、城乡差别和社会经济发展水平有关。表现为北方女青少年的体格生长水平普遍高于南方,城市高于农村,经济发达地区高于相对欠发达地区。作者并就本结果在了解中国青少儿生长发育状况及趋势方面的作用,以及PCA-Q分析程序的实际应用体会进行了讨论。

CLUSTER ANALYSES ON GROWTH AND DEVELOPMENT AMONG 22 PROVINCES' HAN GIRLS

This study was designed to study the morphological differences and similarities of Chinese Han girls' growth and development by using PCA-Q mode cluster analysis (SPSS language). The data consisted of 44 urban and rural cases came from 22 provinces. In each subject, seven anthropometric measures and indices were used for analysing. The results showed significant variations of Chinese Han girls' growth and development existed not only between north and south China, but also between urban and rural areas, and between developed and underdeveloped areas. These variations were shown clearly on the dendrogram, and the geographic and socio-economic factors causing these variations were investigated. The practical use of PCA-Q cluster analysis and its merits in studying Chinese girls' growth and development were also discussed by the authors.
