“…Comparing our findings with previous studies, we found that baPWV among men in Beijing is higher than among Japanese and American males of the same age. Among the women in our study, baPWV was higher than in Japan and closer to values in the United State [ 36 ]. We surmise that these differences relate mainly to lifestyle differences, but in the absence of original data, this can only be confirmed by experiments with larger samples.…”

Background Fat distribution is closely related to vascular stiffness. This study aimed to investigate age and sex differences in fat distribution and brachial-ankle pulse wave velocity (baPWV), and the association between fat parameters and baPWV. Methods A total of 10,811 participants aged 20–59 years were recruited. Measures included waist and hip circumference, waist-to-hip ratio (WHR), body mass index (BMI), percentage body fat (PBF), subcutaneous fat area (SFA), visceral fat area (VFA), and baPWV. Results The results confirm that fat accumulates with age and that men tend to carry more abdominal fat than women in the same age group. The findings also indicate that baPWV increases with age and is significantly higher in men than in women in the same age group. In addition, WHR, VFA, and baPWV were more strongly correlated than baPWV and BMI, SFA, and PBF. Finally, the effects of age, PBF, WHR, and VFA on baPWV were greater for the higher quantiles. Conclusions There are age and sex differences in fat distribution and baPWV. Abdominal obesity is more closely linked to arterial stiffness than overall obesity, and people with higher baPWV are more affected by obesity parameters.

We examined the effects of increasing physical activity on arterial stiffness during hyperglycemia. Nineteen glucose intolerant elderly participated in the study. We randomly assigned 10 participants to increase their daily activity in everyday life, regardless of the time or intensity, for 1 month (PAI group) (age, 74.6 ± 1.3 years; mean ± SE) and nine participants to maintain their level of activity (CON group) (age, 79.2 ± 2.1 years; mean ± SE). The 75 g oral glucose tolerance test was conducted in each participant in both groups before and after the start of the intervention to confirm glucose intolerance. Brachial-ankle pulse wave velocity and cardio ankle vascular index significantly increased from baseline at 30, 60, and 90 min after the 75 g glucose ingestion after the intervention in the CON group (p<0.05), but not in the PAI group. Heart-brachial pulse wave velocity did not change compared to baseline after the 75 g glucose ingestion in either group and did not change from baseline at 30, 60, and 90 min after the 75 g glucose ingestion before and after the intervention in both groups. The present findings indicate that a short term increase in physical activity suppresses the increase in arterial stiffness after glucose intake.

“…Although there were fewer participants in the oldest age group in our study, the addition of participants up to the age of 85þ years adds significantly to the existing knowledge along with the analysis of health and high risk groups. In contrast, a study comparing healthy Japanese and US adults found that there were similar rates of aging between the two counties, except for females, where Japanese females exhibited slower arterial stiffening [26]. However, this study only went up to the age of 69 years using carotid-femoral and brachial-ankle PWV and did not address the impact of cardiovascular risk factors.…”

Background: Most comparisons of arterial stiffness between ethnic groups focus on pulse wave velocity. This study used the cardio-ankle vascular index (CAVI) in European compared to Japanese individuals to investigate how cardiovascular risk factors affect arterial aging across geographic regions.Methods: Four hundred and ninety-four European and 1044 Japanese individuals underwent measurements of CAVI, blood pressure and information on cardiovascular risk factors. Both datasets included individuals with 0-5 cardiovascular risk factors.Results: Average CAVI was higher in the Japanese than the European group in every age category, with significant differences up to 75 years for males and 85 for females. The correlation of CAVI with age, controlled for cardiovascular risk factors, was slightly higher in Japanese females (r ¼ 0.594 vs. Europeans r ¼ 0.542) but much higher in European males (r ¼ 0.710 vs. Japanese r ¼ 0.511). There was a significant correlation between CAVI and total cardiovascular risk factors in the Japanese (r ¼ 0.141, P < 0.001) but not the European group. On linear regression, average CAVI was significantly dependent on age, sex, diabetes, BMI, SBP and geographic region. When divided into 'healthy' vs. 'high risk', the healthy group had a steeper correlation with age for Europeans (r ¼ 0.644 vs. Japanese r ¼ 0.472, Fisher's Z P < 0.001), whereas in the high-risk group, both geographic regions had similar correlations.Conclusion: Japanese patient groups had higher arterial stiffness than Europeans, as measured by CAVI, controlling for cardiovascular risk factors. Europeans had greater increases in arterial stiffness with age in healthy individuals, particularly for males. However, cardiovascular risk factors had a greater impact on the Japanese group.
