          Abstract

          Objective

          Associations between vascular calcification and osteoporosis are well documented, yet effects of lifestyle on atherosclerosis and osteoporosis remain unclear. This study evaluated the relationship between atherosclerosis and osteoporosis of people with different lifestyles living on Uku Island in Japan (rice consumption and fishing lifestyle) and in Ulaanbaatar in Mongolia (meat consumption and nomadic lifestyle), and investigated the differences of lifestyles on atherosclerosis and osteoporosis.

          Methods

          Participants were women aged over 50 years who had undergone a previous medical examination for atherosclerosis and osteoporosis (Uku Island, 104, Ulaanbaatar, 71). Lifestyle habits were obtained by questionnaire. Bone mineral density of the right calcaneus was measured using quantitative ultrasound. Brachial‐ankle pulse wave velocity was measured as an index of atherosclerosis.

          Results

          There were no significant differences in bone mineral density and brachial‐ankle pulse wave velocity between the two groups, even though meat and dairy intake, number of meals skipped, and number of children were significantly greater in participants from Ulaanbaatar compared with Uku Island. Brachial‐ankle pulse wave velocity showed significant positive correlations with age, systolic and diastolic blood pressures, and body mass index and a significant negative correlation with bone mineral density for both groups. With step‐wise multiple regression analysis, brachial‐ankle pulse wave velocity significantly correlated with age and bone mineral density for both populations. Systolic blood pressure significantly correlated with brachial‐ankle pulse wave velocity for the Ulaanbaatar group.

          Conclusions

          Despite significant lifestyle differences, similar relationships between atherosclerosis and osteoporosis were observed in women from Uku Island and Ulaanbaatar. Hypertension was a significant contributing factor for atherosclerosis for the Ulaanbaatar group.

          Validity, reproducibility, and clinical significance of noninvasive brachial-ankle pulse wave velocity measurement.

          The present study was conducted to evaluate the validity and reproducibility of noninvasive brachial-ankle pulse wave velocity (baPWV) measurements and to examine the alteration of baPWV in patients with coronary artery disease (CAD). Simultaneous recordings of baPWV by a simple, noninvasive method and aortic pulse wave velosity (PWV) using a catheter tip with pressure manometer were performed in 41 patients with CAD, vasospastic angina, or cardiomyopathy. In 32 subjects (15 controls and 17 patients with CAD), baPWV was recorded independently by two observers in a random manner. In 55 subjects (14 controls and 41 patients with CAD), baPWV was recorded twice by a single observer on different days. baPWV were compared among 172 patients with CAD (aged 62 +/- 8 years); 655 age-matched patients without CAD but with hypertension, diabetes mellitus, or dyslipidemia; and 595 age-matched healthy subjects without these risk factors. baPWV correlated well with aortic PWV (r=0.87, p<0.01). Pearson's correlation coefficients of interobserver and intraobserver reproducibility were r=0.98 and r=0.87, respectively. The corresponding coefficients of variation were 8.4% and 10.0%. baPWV were significantly higher in CAD patients than in non-CAD patients with risk factors, for both genders (p<0.01). In addition, baPWV were higher in non-CAD patients with risk factors than in healthy subjects without risk factors. Thus, the validity and reproducibility of baPWV measurements are considerably high, and this method seems to be an acceptable marker reflecting vascular damages. baPWV measured by this simple, noninvasive method is suitable for screening vascular damages in a large population.
