摘要
利用SPSS计算机软件的PCA-Q分析程序,对《1985年中国学生体质与健康研究》中汉族7岁男女儿童的生长发育状况进行聚类分析。对象来自全国28个省市自治区,计112组样本,34303人。在主成分分析基础上,通过Q聚类分析,分别将男女儿童分成7和6类。各类儿童生长水平有显著差异,体型表现也各异。分析还表明,以上儿童生长发育的地区差异受城乡差别、地理因素和地区社会经济发展水平等因素的综合影响。
The morphological differences and similarities in growth and development of Chinese Han-Nationality children aged 7were studied with the PCA-Q mode cluster analysis programme of SPSS. 34303 boys and girls from 28 Chinese provinceswere taken as samples and grouped into 112 cases. Based on the principal-component analysis,these cases were clustered into7 categories for boys and 6 for girls, between which there existed significant differences in body size, body build,and othergrowth indexes. The results showed that the differences in growth and development of children from various areas in Chinawere due to a multi-factors effect,such as the gap between cities and rural areas,the geographical features,and the socio-e-conomic development.
