因子分析在代谢综合征研究中的应用

关于代谢综合征(MS)是否存在、构成组分、病理生理学机制及其临床意义等方面存在较多争议.因子分析(FA)是一种寻找潜在因子的模型分析方法,主要包括探索性因子分析(EFA)和验证性因子分析(CFA).至今已有很多关于MS的研究采用FA方法,为MS作为一种综合征的存在及其生物学机制提供了证据.

Use of factor analysis in the study of metabolic syndrome

There are many disputes about the existence,components,pathophysiological mechanisms and clinical significance of metabolic syndrome (MS).Factor analysis (FA) is a mathematical model that explains the covariance between a large set of observed variables in terms of a smaller set of unobsenred latent variables(known as factors).It includes exploratory factor analysis (EFA) and confirmatory factor analysis (CFA).Up to now,there are many studies of MS have used FA to provide evidence for the existence or mechanisms of MS.
