Abstract

This study evaluated the association via partial least squares regression between body mass index (BMI) and body adiposity (BA) with infrared spectra of blood from 46 individuals (controls = 12; prediabetic = 26; diabetic = 8) stratified by fasting blood glucose and glycated hemoglobin (A1c). It was observed a greater absorption at wavelengths related to the spectral regions of 3200-2800 cm-1 and 1500-1200 cm-1 due to contributions of lipids, proteins and carbohydrates in prediabetic and diabetic patients. A strong association between the infrared spectra of blood with BMI (R2 = 0.996, RMSECV = 0.39 kgm-2) and lower intensity with BA (R2 = 0.893; RMSECV = 1.96%) was found.
