摘　　要：背景:根据广西哲学社会科学"十一五"规划2008年度研究项目《广西边远山区聚居少数民族体质与健康发展研究》研究计划,对广西12个聚居少数民族18～22岁人群体质进行综合评价,了解影响少数民族体质各种因素。目的:通过建立因子分析模型,观测变量间极其复杂的相关关系,寻找变量变化潜在的支配因子,解释共性因子的实际意义,客观评价该人群体质健康水平。方法:为了保证样本的同质性、科学性和代表性,参加测试对象父母必须是少数民族,监测少数民族样本为壮族、侗族、瑶族、苗族、毛南族、京族、水族、仡佬族、仫佬族、回族、土家族12个少数民族族。采用现场调研、小样本可行性试验、大样本正式测试和建立指标体系4个步骤,对18560名少数民族人群进行体质测试,求出因子特征向量、特征值和贡献率。建立初始因子模型、旋转后的因子模型,了解广西聚居少数民族人群体质因子结构,并对人群的健康水平综合评价。观测身高、体质量、肺活量、立位体前屈、立定跳远、台阶指数各项指标。结果与结论:广西聚居少数民族人群体质因子结构:健康因子、营养因子、有氧代谢因子的状况。健康因子只有肺活量、体前屈、立定跳远是正数,其余3项为负数。3个共性因子对体质的贡献率分别为K1=61.551、K2=15.264%、K3=9.818%,总贡献率达到86.633%。其中健康因子最好是毛南族、其次仡佬族、第三是土家族。营养因子最好是水族、第二苗族、第三京族。有氧代谢因子的排序是仡佬族、毛南族、土家族。通过建立因子分析模型,解释共性因子的实际意义,能客观评价各少数民族人群体质健康水平。BACKGROUND：According to 2008＇s Guangxi philosophical and social science ＂eleventh five-year plan＂ studying item of ＂constitution and health developing research on Guangxi gathering minority in remote mountainous areas＂,this paper has an integrative evaluation on the twelve gathering minorities in Guangxi from the age of 18 to 22 years,and explores all the affected factors to minority＇s constitution.OBJECTIVE：By designing factor analysis model and observing the most complicated correlativity among variables,the authors try to find out the potential dominating factor for variables＇ change,to explain the practice meaning of common factors and to evaluate constitution health level of the minority with impersonality.METHODS：In order to make sure sample＇s homogenicity,science and representation,the tested objects＇ parents must be minority and the tested minority samples were the Chuang,the Dong,the Yao,the Miao,the Maonan,the Jing,the Shui,the Gelao,the Mulao,the Hui,the Tujia.With the four steps of spot investigation,small sample test for feasibility,large sample normal test and designing index system,the authors tested the constitution of 18 560 minorities.The authors get factor eigenvector,eigenvalue and contribution rate.Then designed initial factor model and factor model after rotation,know about the factor structure of Guangxi gathering minority,and have an integrative evaluation for the group＇s health by observing the index of stature,body weight,vital capacity,standing proneness,halt long-jump and step jump.RESULTS AND CONCLUSION：The minority group＇s constitution structures are health factor,nutrition factor and aerobic metabolism factor.Health factor only includes positive number in vital capacity,body anteflexion,standing long jump,but negative number in other three items.They respective contribution to constitution are K1=61.551%,K2=15.264%,K3=9.818%,and the general contribution rate is 86.333%.The best health factor is the Maonan,then the Gelao and the Tujia;the best nutrition
