Objective: Postprandial (pp) lipid metabolism is associated with insulin resistance and type 2 diabetes. In young men, pp triglycerides (TGs) are more strongly associated with traits of metabolic syndrome (MS) than fasting TGs. We established a cohort of middle-aged men selected for traits of MS and pp lipid metabolism to determine if fasting TGs or pp TGs are more closely related to MS.
Research design and methods: A total of 1558 men were characterized for MS. A total of 755 men underwent an oral metabolic tolerance test consisting of a standardized high-fat meal and an oral glucose tolerance test. Blood samples were drawn in the fasting state and hourly until 9 h to determine pp TGs and free fatty acids. Glucose and insulin were analyzed until 5 h pp.
Results: In the overall cohort, 329 subjects (21.1%) had a complete MS based on the Adult Treatment Panel III criteria, and 650 subjects (41.7%) had a complete MS based on the International Diabetes Federation criteria. The association of pp TGs with MS parameters was not stronger than the association of fasting TGs with them. Pp TGs were independently associated with beta-cell function.
Conclusions: Pp TGs did not show a higher correlation with MS traits than fasting TGs. This finding is probably due to the high incidence of overweight subjects in this middle-aged cohort.
