Relationship between dyslipidemia and early vascular lesions in obese children and adolescents
OBJECTIVE: Obese children and adolescents are often complicated with the abnormalities of lipid and glucose metabolism, which are often associated with adulthood hypertension, diabetes and cardiovascular disease. In this study, the blood lipids, blood pressure and carotid arterial intima-media thick...

| Zusammenfassung: | OBJECTIVE: Obese children and adolescents are often complicated with the abnormalities of lipid and glucose metabolism, which are often associated with adulthood hypertension, diabetes and cardiovascular disease. In this study, the blood lipids, blood pressure and carotid arterial intima-media thickness (IMT) in obese children and adolescents were measured to investigate the relationship between the dyslipidemia and early vascular lesions METHOD: A total of 580 obese children and adolescents aged from 7 to 17 years of age were enrolled from 3 hospitals from Jan. 2008 to Sept. 2009. They were divided into 2 groups according to their blood lipoid levels. Ortholiposis group included 100 males and 52 females with a mean age of 10.47 years and a mean body mass index (BMI) of 28.28 kg/m(2). Dyslipidemia group included 305 males and 123 females with a mean age of 10.83 years and a mean BMI of 27.60 kg/m(2). Physical examination, and measurement of blood lipid, glucose and liver enzyme were taken. Carotid IMT was measured for 285 subjects RESULT: (1) Hypertension was found in 12.5% (19/152) and 20.1% (86/428) patients in ortholiposis and dyslipidemia groups, respectively, with a significant difference (χ(2) = 4.362, P = 0.037). The OR was 1.760 with 95% confidence interval of 1.030 - 3.008. Higher prevalence of hypertension was found in patients with dyslipidemia. (2) The left, right and mean common carotid IMTs of dyslipidemia group were higher than those of ortholiposis group without significant difference (all P > 0.05). The left, right and mean internal carotid IMTs in dyslipidemia group were (0.66 ± 0.15) mm, (0.65 ± 0.15) mm and (0.65 ± 0.15) mm, respectively while these in ortholiposis group were (0.62 ± 0.13) mm, (0.60 ± 0.13) mm and (0.61 ± 0.12) mm, respectively (P < 0.05 for all). (3) Bivariate correlation analysis showed that systolic blood pressure was positively correlated with age, BMI, BMI Z score, waist circumference, hip circumference, uric acid, alanine transaminase, triglyceride, fasting insulin and insulin resistance index (P < 0.05 for all). Moreover, mean carotid and internal carotid IMTs were positively correlated with age, BMI, waist circumference, hip circumference, and triglyceride (all P < 0.05). Multiple linear regression analysis showed that hip circumference and insulin resistance index were independent determinants of systolic pressure. Waist circumference was independent determinant of mean common and internal carotid IMT and triglyceride was independent determinants of mean internal carotid IMT CONCLUSION: (1) Vascular lesions, including hypertension and thicker tunica intima are common in obese children and adolescents. (2) Vascular lesions are closely related with dyslipidemia, and waist circumference and hypertriglyceridemia are the risk factors |
