RESUMEN
BACKGROUND: Overweight is always accompanied by hypertriglyceridemia (HTG), but the change in non-fasting triglyceride (TG) concentration in overweight subjects without postprandial hypertriglyceridemia was unknown. METHODS: Concentrations of serum lipids were measured at 2 and 4â¯h in matched overweight (OW group, nâ¯=â¯54) and control subjects (CON group, nâ¯=â¯55) after a daily meal. Concentrations of remnant cholesterol and non-HDL cholesterol were calculated according to the formulas. The diagnostic criteria for non-fasting HTG were based on 2 different consensus statement. ROC curve was used to determine the pointcut of postprandial HTG. RESULTS: OW group had higher fasting concentrations of RC and non-HDL-C than CON group. Non-fasting concentrations of triglyceride and RC significantly increased in 2 groups while were higher in OW group (pâ¯<â¯.05). The proportion of non-fasting HTG increased after a daily meal in OW group was significantly higher than the percentage of fasting HTG (pâ¯<â¯.05). There was a significant correlation between the postprandial concentrations of TG and RC. CONCLUSIONS: Overweight subjects were more likely to develop non-fasting hypertriglyceridemia and higher concentrations of RC and non-HDL-C. Additionally, 2.0â¯mmol/l at 4â¯h after breakfast could be a pointcut value to detect changes in lipid profile of Chinese overweight people.
