Abstract
Background: An elevated postprandial triglyceride response is a risk factor for cardiovascular disease. Past studies reported greater post-prandial lipemia in small samples of people with obesity. However, data describing the relationship between body mass index (BMI) and postprandial triglycerides across a wide range of BMI is lacking. We investigated the relationship between BMI and body composition with postprandial lipemia in a large sample of adults with normal weight, overweight, and obesity. Methods: This is a secondary analysis of six studies from our laboratory with a total of 159 adults (age 18-84 years) free of diabetes or cardiovascular disease, including 58 classified as normal weight, 54 overweight, 32 with class I obesity, and 13 with class II or III obesity. Body composition was measured using bioelectrical impedance. Participants completed an abbreviated fat tolerance test wherein triglycerides were measured fasting and 4 h after a high-fat meal (9 kcal/kg). Postprandial triglycerides were compared across BMI categories and correlated with BMI, waist circumference, body fat percent and muscle mass percent. Results: Postprandial triglycerides differed based on BMI (p = 0.004), although only the normal weight (118.3 ± 57.0 mg/dL) versus class II/III obesity (183.5 ± 96.7 mg/dL) categories were significantly different (p = 0.006). Postprandial triglycerides in adults with overweight (140.4 ± 59.2 mg/dL) and class I obesity (155.5 ± 68.7 mg/dL) were intermediate. After adjusting for age and sex, postprandial triglycerides were weakly positively correlated with BMI (r = 0.24; p = 0.007), waist circumference (r = 0.29; p = 0.001), and body fat percent (r = 0.29; p = 0.001), and weakly inversely associated with muscle mass percent (r = -0.28; p = 0.001). Conclusions: In a sample of 159 adults across the BMI spectrum, BMI and body composition were weakly associated with postprandial triglycerides. Our data suggest BMI and body composition are modest determinants of postprandial triglycerides.
