[Comparison of the casual serum triglyceride levels at health check-up with the values during fasting].
Since higher levels of serum triglycerides were frequently found during the UOEH physical check-up for employees and students in 1989, we analysed subjects with higher triglyceride levels and discussed ways of handling them. Blood sampling to determine serum lipids was done between 13:00-15:00. Of the total (males 1257, females 1267), 272 had higher serum triglyceride levels (over 200 mg/dl) (males 246, females 26) (1st TG). One hundred and twenty-one of the group with higher TG levels in the 1st examination were reevaluated by blood sampling the morning after overnight fasting (2nd TG). There was a significant positive correlationship between the TG levels from the 1st examination and those from the 2nd examination (r = 0.62, n = 121, P < 0.0001). The predictive value calculated from the equation between the TG in the first and second measurements was 341.7 mg/dl. There was a 14.9% rate of false negatives in subjects under 341.7 mg/dl on the first TG measurement. However, there were only 6.3% false negatives in the subjects under 250 mg/dl on the first TG measurement. Age, body mass index and serum cholesterol level were significantly higher in the group with the higher TG level on reevaluation (more than 160 mg/dl) than those in the group with the lower TG level on reevaluation (less than 160 mg/dl). We concluded from these results that the casual serum TG levels above 250 mg/dl might be a suitable cut off level in physical check-ups.
