Key result
Higher pulse wave velocity tracks with higher blood pressure and body mass in healthy adolescents.
Why the study?
Pulse wave velocity and ankle brachial index are non-invasive measures related to cardiovascular risk, but normal values and correlations in healthy adolescents were not established.
Cross-Sectional (n=392)

Correlations in healthy Korean adolescents are hypothesis-generating; prospective studies needed before considering PWV for adolescent BP assessment.
Purpose : Pulse wave velocity (PWV) and ankle brachial index (ABI) are simple, non-invasive methods to assess arterial stiffness. These parameters are also known to be closely related to cardiovascular risk factors and diseases. The purposes of this study were to measure blood pressure, PWV, ABI in healthy Korean adolescents, set up their normal values and assess their correlations. Methods : Three hundred ninety two healthy adolescents (213 boys and 179 girls) underwent measurement of brachial ankle pulse wave velocity (baPWV), ABI, body mass index(BMI) and blood pressure from four extremities. Linear regression analysis was performed to reveal the correlations between PWV, ABI and independent variables. Results : Blood pressure and PWV were significantly higher in all extremities in males compared to females. Blood pressure of both brachial and ankle showed positive correlation with body weight, height, and BMI, whereas ABI showed no correlation with any of these indices. Conclusion : Blood pressure increases as body weight, height and BMI increases. PWV shows positive correlation with blood pressure. It will be helpful to predict the risks of cardiovascular diseases in adolescents.

Kim et al. (2007) conducted a cross-sectional in Healthy (n=392). Blood pressure and body indices (weight, height, BMI) was evaluated on Correlation between pulse wave velocity, ankle brachial index, and independent variables (blood pressure, body indices). In healthy Korean adolescents, pulse wave velocity showed a positive correlation with blood pressure, which itself correlated positively with body weight, height, and body mass index.
