ABSTRACT
OBJECTIVE:
To examine the association of apolipoproteins with arterial stiffness and carotid artery structure in children and adolescents. STUDYDESIGN:
A total of 338 children and adolescents (178 female) with a mean age 13.0 ± 2.8 years were examined. Apolipoproteins (AI, AII, B100, CII, CIII, and E) were measured via human apolipoprotein magnetic bead panel. Applanation tonometry determined pulse wave velocity and ultrasound imaging measured carotid intima-media thickness. Dual X-ray absorptiometry measured total body fat percent. Linear regression models were adjusted for Tanner stage, sex, and race with further adjustments for body fat percent. Linear regression models also examined the interaction between Tanner stage and apolipoproteins.RESULTS:
There was a significant positive association between pulse wave velocity and apolipoproteins AI (0.015 m/s/10 µg/mL [CI 0.005-0.026], P = .003), AII (0.036 m/s/10 µg/mL [0.017-0.056], P < .001), B100 (0.009 m/s/10 µg/mL [0.002-0.016], P = .012), E (0.158 m/s/10 µg/mL [0.080-0.235], P < .001), and CIIICII (0.033/µg/mL [0.014-0.052], P < .001). After we added body fat percent to the models, pulse wave velocity (PWV) remained positively associated with greater levels of apolipoproteins AI, AII, B100, E, and CIIICII. Both with and without the adjustment for body fat percent, there were no significant associations between any apolipoprotein and carotid intima-media thickness. There were no significant interactions between Tanner stage and apolipoproteins.CONCLUSIONS:
These findings suggest that greater levels of apolipoprotein AII, E, and CIIICII are associated with increased arterial stiffness in children and adolescents, both with and without adjusting for percent body fat. These specific apolipoproteins may be useful as biomarkers of cardiovascular risk.Palavras-chave
