Profile and associations of carotid femoral pulse wave velocity in a community-based Beijing population of middle and old age / 中华心血管病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the profile and related factors of carotid femoral pulse wave velocity (CFPWV) in a community-based Beijing population of middle and old age.</p><p><b>METHODS</b>A total of 1519 residents aged 44 - 79 years old from Shijingshan district, Beijing, were recruited for the cardiovascular risk factor survey and CFPWV measurements. One way ANOVA, pearson correlation and partial correlation, stepwise multi-linear regression were used for the data analysis.</p><p><b>RESULTS</b>(1) The age-adjusted mean value of CFPWV was significantly higher in men than that in women (11.4 vs. 11.1 m/s, P = 0.007). CFPWV increased significantly with age both for men and women (all P < 0.01). (2) After adjusting for age and gender, CFPWV was significantly higher in people with hypertension, diabetes and higher heart rate (> 70 beats/min) than people without these factors (P < 0.01). (3) CFPWV significantly correlated with age, systolic blood pressure, diastolic blood pressure, fasting blood glucose and heart rate (correlation coefficient ranged from 0.12 - 0.46, all P < 0.01). In female, CFPWV was positively correlated with total cholesterol and triglycerides (correlation coefficient 0.11 and 0.13, all P < 0.01). Multi-linear regression analysis showed age, gender, systolic blood pressure, diastolic blood pressure, fasting blood glucose and heart rate were independent predictors of CFPWV.</p><p><b>CONCLUSION</b>In this middle and old age Chinese population, age, sex, systolic blood pressure, diastolic blood pressure, fasting blood glucose and heart rate but not HDL-cholesterol and body mass index were associated with CFPWV.</p>
