Postprandial hyperlipidemia: another correlate of the "hypertriglyceridemic waist" phenotype in men.

Abstract Fasting hypertriglyceridemia has been reported to be predictive of an exaggerated triglyceride (TG) response to an oral fat load. Abdominal obesity has also been associated with postprandial hyperlipidemia. The objective of the present study was to quantify the contribution of abdominal obesity and fasting hypertriglyceridemia to the magnitude of postprandial lipemia. For that purpose, potential differences in postprandial TG-rich lipoprotein (TRL) levels were examined among men characterized by the absence/presence of the “hypertriglyceridemic waist” phenotype following a standardized breakfast with a high fat content (64% calories as fat). Sixty-nine men (mean age±S.D.: 45.1±10.5 years) were classified according to waist girth ( P
