Individuals with a predominance of small low-density lipoprotein (LDL) particles appear to be at increased risk for coronary artery disease. The purpose of this study was to determine whether the LDL particle size was modulated in response to a 75-g oral glucose load. Overall, there were no significant changes in the LDL particle size after glucose load. However, the difference in LDL particle size (ΔLDL size) between the fasting and 2-h post-load states was inversely correlated with the fasting LDL particle size. Also, ΔLDL size was positively correlated with BMI and the post-load glucose levels. Forward stepwise regression analysis revealed three parameters as independent factors capable of modulating LDL particle size: BMI, fasting insulin, and post-load glucose levels. After adjustment for BMI and glucose levels, the levels of fasting and 2-h post-load insulin remain independent determinants of ΔLDL size. These results suggest that plasma insulin levels during glucose load modulate LDL particle size. Copyright (C) 1998 Elsevier Science B.V.
