Together with hypertension, obesity, impaired glucose tolerance, low HDL-c, hyperuricemia and fatty liver, hypertriglyceridemia constitutes a plurimetabolic syndrome. However, the relationship of triglycerides with the incidence of other disorders have not been clarified. We examined the incidence of metabolic disorders in the function of serum triglycerides levels. A total of 510 males and 310 females who had an annual health check were subgrouped according to serum triglycerides levels: less than 100 mg/dl, 100-149 mg/dl, 150-199 mg/dl, 200-299 mg/dl, 300-399 mg/dl and over 400 mg/dl. The incidence rates of the disorders above were gained for each subgroups in both male and female. They all increased more lineally with serum triglycerides levels than with serum cholesterol levels.
