中文摘要: 
食管癌的筛查除与防治策略本身有关外，还与人群的认识和接受程度有很大关系?，接受程度高其顺应性就高，反之亦然，从而影响阳性病例的检出率及早期诊断率。为此本研究对磁县食管癌早诊早治普查顺应性进行分析，探讨高发区食管癌内镜普查的影响因素，以提高食管癌早诊率。 
英文摘要: 
To elucidate the principal of orthogonal factor analysis, using an example of factor analysis of metabolic syndrome. The basic structures and the fundamental concepts of orthogonal factor analysis were introduced and data involving 1877 women aged of 3565 years,selected from a crosssectional study,which was conducted in 1998一2001 in Shanghai,were included in this study. Factor analysis was carried out using principle components analysis with Varimax orthogonal rotation of the components of the metabolic syndrome. The different components of the metabolic syndrome were not linked closely with the other components and loaded on the six different factors,which mainly reflected by the variables of obesity, blood pressure, plasma glucose, plasma insulin, triglycerides and IIDLcholesterol respectively. Six major factors of the metabolic syndrome were uncorrelated with each other and explained 86% of the variance in the original data. The factor score and total factor score for the individual could be obtained according to the component score coefficient matrix. Although the components of the metabolic syndrome were related statistically, the finding of six factors suggested that the components of the metabolic syndrome did not show high degrees of intercorrelation. As a linear method of data reduction, the mode reduced a large set of measured intercorrelation variables into a smaller set of uncorreiated factors, which explained the majority of the variance in the original variables. Factor analysis was well suited for revealing underlying patterns or
structure among variables showing high degrees of intercorrelation
