Objective: To evaluate the relationship between remnant cholesterol and carotid intima-media thickness (cIMT), a surrogate marker for atherosclerosis, in children and adolescents. Study design: Anthropometric, laboratory, liver, and carotid ultrasonographic data were obtained from 767 youths (594, overweight/obese; 173, normal weight). Fasting remnant cholesterol was calculated from the standard lipid profile. cIMT ≥0.56 mm (corresponding to the 90th percentile of values observed in normal-weight children) was chosen to define elevated cIMT. Logistic regression analysis was used to estimate the risk of elevated cIMT according to tertiles of remnant cholesterol levels. Results: In the entire cohort, the mean concentration of remnant cholesterol was 17.9 ± 10.3 mg/dL and mean cIMT value was 0.51 ± 0.8 mm. Remnant cholesterol significantly correlated with age, sex, body mass index, waist circumference, blood pressure, lipids, liver enzymes, and insulin resistance. cIMT value increased progressively with rising remnant cholesterol tertiles (Pfor trend < .001). Compared with subjects in the lowest remnant cholesterol tertile, those in the middle and highest remnant cholesterol tertiles had a 2.3- and 2.4-fold increased risk of elevated cIMT, independently of age, sex, pubertal stage, body mass index, and apolipoprotein B (all Padj ≤ .003). When the effects of overweight/obesity on the association between remnant cholesterol and cIMT were determined, normal-weight as well as overweight/obese subjects in the highest remnant cholesterol tertile had a 3.8- and 2.3-fold increased risk to have elevated cIMT compared with the respective study groups in the lowest tertile, after adjustment for conventional risk factors (Padj = .038 and Padj = .003, respectively). Conclusions: In youths, elevated levels of remnant cholesterol might represent a marker of early atherosclerotic damage.

Abstract

Objective: To evaluate the relationship between remnant cholesterol and carotid intima-media thickness (cIMT), a surrogate marker for atherosclerosis, in children and adolescents. Study design: Anthropometric, laboratory, liver, and carotid ultrasonographic data were obtained from 767 youths (594, overweight/obese; 173, normal weight). Fasting remnant cholesterol was calculated from the standard lipid profile. cIMT ≥0.56 mm (corresponding to the 90th percentile of values observed in normal-weight children) was chosen to define elevated cIMT. Logistic regression analysis was used to estimate the risk of elevated cIMT according to tertiles of remnant cholesterol levels. Results: In the entire cohort, the mean concentration of remnant cholesterol was 17.9 ± 10.3 mg/dL and mean cIMT value was 0.51 ± 0.8 mm. Remnant cholesterol significantly correlated with age, sex, body mass index, waist circumference, blood pressure, lipids, liver enzymes, and insulin resistance. cIMT value increased progressively with rising remnant cholesterol tertiles (Pfor trend < .001). Compared with subjects in the lowest remnant cholesterol tertile, those in the middle and highest remnant cholesterol tertiles had a 2.3- and 2.4-fold increased risk of elevated cIMT, independently of age, sex, pubertal stage, body mass index, and apolipoprotein B (all Padj ≤ .003). When the effects of overweight/obesity on the association between remnant cholesterol and cIMT were determined, normal-weight as well as overweight/obese subjects in the highest remnant cholesterol tertile had a 3.8- and 2.3-fold increased risk to have elevated cIMT compared with the respective study groups in the lowest tertile, after adjustment for conventional risk factors (Padj = .038 and Padj = .003, respectively). Conclusions: In youths, elevated levels of remnant cholesterol might represent a marker of early atherosclerotic damage.
