Factor analyses of metabolic syndrome: A systematic review with special reference to Asian Indians

Metabolic syndrome is the constellation of cardiovascular disease risk factors and a growing public health issue affecting more than 20% of world population. Factor analysis is a powerful mathematical tool in exploring the underlying factors of any chronic diseases. Although it is most often criticized for its contrasting results for a common expression differently interpreted by the researchers yet fit the original data equally well.

The present study aims to find out the underlying physiological domains for the phenotypic attribution of metabolic syndrome as documented in several studies.

Literature search was done using Google Scholar, PUBMED, Research Gate and manual searching to identify relevant studies of the selected topic.

More than one physiological domain has been explored for the expression of metabolic syndrome explored in different studies. A reason for this disparity may be because most of explored factors are just mathematically significant but not biologically. Another reason may be the varied factor load concern. Therefore, a fixed factor load value is needed to be restricted for all studies across world.
