EVALUATION OF BLOOD PRESSURE AND PULSE WAVE VELOCITY IN HEALTHY YOUTHS WITH/WITHOUT SPORTS CUSTOMS

Abstract

Objective: Pulse Wave Velocity (PWV) was an examination to measure the level of atherosclelosis. Previous report showed that risk factor of atherosclelosis as hypertension, diabetes mellitus, hyperlipidemia, aging, smoking made PWV faster. On other studies, PWV in non-smoking youths were associated with obese and hyperlipidemia (Intern Med. 2005; 44:696–701.). Aim: Correlation PWV with other risk factors were not elucidated. In this study, first, we featured to the relationship between PWV and Familial History (FH) and Blood Pressure (BP) in Healthy, non-smoking youths without abnormal data of blood test in medical examination (blood sugar, lipid, liver and renal function). And next, we paid attention to the difference in risk mitigation due to the presence or absence of sports customs. Design and method: Non-smoking healthy youths,72 men and 30 women with chance sports customs (CSC), 36 men and 15 women with daily sports customs (DSC), without abnormal data of blood test in medical examination was entry in this study. If he or she had a familial history of hypertension, diabetes mellitus, hyperlipidemia, ischemic heart disease, cerebrovascular disease in father or mother, it counted as two point, and also in grandfather or grandmother, as one point by each risk factor. And in this study, called three former risk factors as “disease risk (DR)”, two latter risk factors as “outbreak risk (OR)”. Results: Mean PWV was faster in men and women with CSC than those with DSC. Next we sort these data into ascending-order, and devided into “low PWV (LP)” and “high PWV (HP)” bound on the median. Both PWV of Men and women recorded HP is faster than recorded LP with CSC and DSC, however in BP, both Men and women recorded HP is faster than recorded LP with CSC but these difference in men and women with DSC has tendency to shirink statistically. Conclusions: We conclude that familial history and BP may correlate with PWV in healthy youths with chance sports customs especially in HP. But daily sports customs pretend to rise their BP.
