Canonical correlation between anthropometric parameters and blood glucose level

  Objective   To investigate the associatio n between blood glucose levels and a set of human body par ameters in order to determine which anthropometric parameter correlated mosthig hly with the blood glucose level.

  Methods   Data needed for this analysis were available from a survey of diabetes risk factors in the community residents of Shanghai urban areas, collected data including body height and weight; waist and hip circumferences; after calculating body mass index(BMI), waist/hip ratio(WHR), the association of the anthropometr ic parameters with FPG and OGTT was explored by canonical correlation analysis.

  Results   Canonical correlations were satistically significance between the anthropometric parameters and blood glucose levels in all sex-age-specific groups.Of the anthropometric variables, waist consistently demonstr ated the highest correlation coefficients with FPG and 2-hour OGTT, while BMI ranked second.Of the blood glucose variables, the correlation coefficient of OGTT with body parameters was generally the highest.

  Conclusion   Waist circumferences was most highly correlated with blood glucose levels; and compared with FPG, 2-hour OGTT indicated a stronger association with an- thropometric parameters.
