AbstractPrevention of cardiovascular disease (CVD) is a public health challenge. Arterial stiffness is an index that indicates the risk of developing CVD. The lifestyle habits of working generations vary greatly with age; however, no study has examined the age-specific determinants of brachial-ankle pulse wave velocity (baPWV), an index of arterial stiffness. In this cross-sectional study, we aimed to identify the age-specific determinants of baPWV. From 2014 to 2017 fiscal years, health measurements were conducted at seven companies. Overall, 1,403 men, aged between 25 and 64 years, were categorized according to age. Their lifestyle habits, body composition, and hemodynamics were recorded. Multiple regression analyses using the stepwise method revealed that higher baPWV was associated with increasing age. baPWV was also increased with increasing systolic and diastolic blood pressure and heart rate across all age groups. The increased baPWV was significantly associated with the presence of metabolic syndrome component factors in the age group of 45-54 years, high smoking index in the age groups of 25-44 years and 55-64 years, low body mass index in the 55-64 age group, and low skeletal muscle index in the 35-54 age group. Total physical activity was inversely associated with baPWV in the two age groups of 45-54 and 55-64 years. In conclusion, hemodynamics significantly affected baPWV across all ages, while smoking index, total physical activity, body mass index, and skeletal muscle index affected baPWV depending on the age group. Thus, age-related strategies should be established for alleviating baPWV increase.
