Abstract. Dyslipidemia in childhood predicts the development of atherosclerosis in young adults. The aim of this study is to investigate the relation of apoB/apoA-I ratio with different cardiovascular risk factors, in obese children. A total of 41 overweight obese children and 30 healthy children were enrolled. Correlations between apoB/apoA-I ratio with different cardiovascular risk factors: C reactive protein (CRP), blood pressure, dyslipidemia markers, gamma-glutamyl transferase activity were calculated. Ultrasounds were used for carotid intima-media thickness (IMT) and fatty liver estimation. All the studied parameters were higher in obese children versus normal subjects. ApoB/apoA-I ratio was correlated (p < 0.05) with γ-GT activity (r = 0.35), IMT (r = 0.38), CRP (r = 0.59), alanine aminotransferase activity (r = 0.37), waist circumference (r = 0.44) and diastolic blood pressure (r = 0.33), while apoA-I was inversely related to triglycerides (r = –0.44), CRP (r = –0.39) and waist circumference (r = –0.42). HDL-C was positively correlated with apoA-I (r = 0.82) and negatively with apoB/apoA-I (r = –0.65), while LDL-C was positively correlated with apoB (r = 0.79). The apoB/apo A-I ratio is higher in obese children than in normal children. The ratio is correlated with increased values of other cardiovascular risk factors and fatty liver markers.
Key words: obesity, children, apoB/apoA-I ratio, atherosclerosis, intima-media thickness, cardiovascular risk factors.
