BACKGROUND Measurement of pulse wave velocity (PWV) is a useful approach for evaluating the severity of atherosclerosis in adults, and, in particular, the measurement of brachial-ankle PWV (baPWV) has been commonly reported as a simple and practicable method. We attempted to investigate how baPWV in healthy children changes with age and gender, in order to assess baPWV in children with risk factors for the early progression of systemic atherosclerosis. METHODS We measured baPWV in 970 healthy Japanese children (500 boys and 470 girls), and set up the normal baPWV values of children on the basis of age and gender. We also performed linear regression analysis and step-wise multiple regression analysis for evaluating its correlation with baPWV and independent variables for baPWV in children. RESULTS The values of baPWV in children were higher in boys than in girls, and baPWV increased with age in both genders. Age, blood pressure and heart rate (HR) were significant determinants of baPWV in both male and female subjects, while the obesity index had no correlation with baPWV. CONCLUSIONS On the basis of these results, we suggest that baPWV in children is largely influenced by age and gender, and that baPWV gradually increased with age in both genders.

D008297 Male Males
D011673 Pulsatile Flow Rhythmic, intermittent propagation of a fluid through a BLOOD VESSEL or piping system, in contrast to constant, smooth propagation, which produces laminar flow. Flow, Pulsating,Perfusion, Pulsatile,Flow, Pulsatile,Flows, Pulsatile,Flows, Pulsating,Perfusions, Pulsatile,Pulsatile Flows,Pulsatile Perfusion,Pulsatile Perfusions,Pulsating Flow,Pulsating Flows
D012016 Reference Values The range or frequency distribution of a measurement in a population (of organisms, organs or things) that has not been selected for the presence of disease or abnormality. Normal Range,Normal Values,Reference Ranges,Normal Ranges,Normal Value,Range, Normal,Range, Reference,Ranges, Normal,Ranges, Reference,Reference Range,Reference Value,Value, Normal,Value, Reference,Values, Normal,Values, Reference
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.
