Atherosclerosis, beginning in childhood, is dependent on several risk factors and may be predictive of coronary artery disease in adulthood. The risk factors for subclinical atherosclerosis are similar to those for clinical disease. Carotid intima-media thickness is a measure of subclinical atherosclerosis and a predictor of subsequent vascular events. This study aimed to examine the relationships of carotid intima-media thickness with known risk factors in asymptomatic children. Family history of cardiovascular disease was collected, together with anthropometric, demographic, and clinical data. Body mass index z-scores were calculated. Serum glucose, lipid fractions, fibrinogen, and C-reactive protein were determined. High-resolution ultrasonography was used to assess intima-media thickness. Associations and relationships of risk factors with composite intima-media thickness were explored. The study enrolled 93 children (44 girls) ranging in age from 49 to 169 months. The boys had a thicker intima-media (0.46 +/- 0.06 mm) than the girls (0.43 +/- 0.06 mm; p = 0.028). The unadjusted triglyceride levels were significantly higher in the overweight and obese children (p = 0.010). Body mass index and overweight/obesity were positively related to intima-media thickness (r = 0.259; p = 0.012 and r (s) = 0.230; p = 0.027, respectively), whereas family history of cardiovascular disease was unrelated. Only gender and overweight/obesity were related to intima-media thickness in a multiple linear regression model (R (2) = 0.125; p = 0.002). Male gender and overweight/obesity were associated with increased intima-media thickness, whereas family history of cardiovascular disease was unrelated.

UI MeSH Term Description Entries
D008055 Lipids A generic term for fats and lipoids, the alcohol-ether-soluble constituents of protoplasm, which are insoluble in water. They comprise the fats, fatty oils, essential oils, waxes, phospholipids, glycolipids, sulfolipids, aminolipids, chromolipids (lipochromes), and fatty acids. (Grant & Hackh's Chemical Dictionary, 5th ed) Lipid
D008297 Male Males
D009765 Obesity A status with BODY WEIGHT that is grossly above the recommended standards, usually due to accumulation of excess FATS in the body. The standards may vary with age, sex, genetic or cultural background. In the BODY MASS INDEX, a BMI greater than 30.0 kg/m2 is considered obese, and a BMI greater than 40.0 kg/m2 is considered morbidly obese (MORBID OBESITY).
D011795 Surveys and Questionnaires Collections of data obtained from voluntary subjects. The information usually takes the form of answers to questions, or suggestions.

D012044 Regression Analysis Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.

D001938 Brazil A country located on the eastern coast of South America, located between Colombia and Peru, that borders the Atlantic Ocean. It is bordered on the north by Venezuela, Guyana, Suriname, and French Guiana, on the south by Uruguay, and on the west by Argentina. The capital is Brasilia.
D002097 C-Reactive Protein A plasma protein that circulates in increased amounts during inflammation and after tissue damage. C-Reactive Protein measured by more sensitive methods often for coronary heart disease risk assessment is referred to as High Sensitivity C-Reactive Protein (hs-CRP).
