[Purpose] No study has examined whether the determinants of longitudinal changes in brachial-ankle pulse wave velocity differ depending on the baseline brachial-ankle pulse wave velocity values. Therefore, this study aimed to extract these determinants in high- and low-value groups based on the FY2014 brachial-ankle pulse wave velocity values. [Participants and Methods] Participants were 97 male workers who underwent continuous health assessments from FY2014 to four years later. Their demographic, lifestyle, body-composition, and hemodynamic data were recorded. First-year data were subtracted from data obtained four years later for each continuous variable item, and the difference divided by the number of years was considered as the annual change. Based on the first-year median brachial-ankle pulse wave velocity, participants were classified into high- and low-brachial-ankle pulse wave velocity groups, i.e., high- and low-value groups, respectively. Multiple regression analysis was performed with the annual change in brachial-ankle pulse wave velocity serving as the dependent variable for both groups. [Results] In comparison with the values obtained in the first year, brachial-ankle pulse wave velocity obtained four years later increased significantly in the low-value group and tended to increase in the high-value group. Increased visceral fat area in the high-value group and increased diastolic blood pressure and heart rate in the low-value group were associated with worsening brachial-ankle pulse wave velocity. [Conclusion] The determinants of longitudinal changes in the brachial-ankle pulse wave velocity differed depending on the baseline brachial-ankle pulse wave velocity values.
[目的] 尚无研究探讨肱踝脉搏波速度纵向变化的决定因素是否因肱踝脉搏波速度基线值而异。因此，本研究旨在根据2014财年的肱踝脉搏波速度值，在高值组和低值组中提取这些决定因素。[参与者与方法] 参与者为97名男性工人，他们在2014财年至四年后接受了连续的健康评估。记录了他们的人口统计学、生活方式、身体成分和血液动力学数据。对于每个连续变量项目，从四年后获得的数据中减去第一年的数据，并将差值除以年数作为年变化量。根据第一年肱踝脉搏波速度的中位数，参与者分别被分为高、低肱踝脉搏波速度组，即高值组和低值组。两组均以肱踝脉搏波速度的年变化量作为因变量进行多元回归分析。[结果] 与第一年获得的值相比，四年后低值组的肱踝脉搏波速度显著增加，高值组则有增加趋势。高值组内脏脂肪面积增加以及低值组舒张压和心率增加与肱踝脉搏波速度恶化有关。[结论] 肱踝脉搏波速度纵向变化的决定因素因肱踝脉搏波速度基线值而异。
