Abstract:
Objective To investigate the impact of different levels of systolic blood pressure on brachial-ankle pulse wave velocity(baPWV). Methods A total of 5 852 participants was selected with stratified random sampling from the 101 510 workers of Tangshan Kaiuan Company who had undergone a physical check-up program. 5 222 of them with integral data were recruited into this survey. According to SBP collected during the 2010-2011 health examination program,the population under observation was divided into four groups:optimal SBP(SBP<120 mmHg),high-normal blood pressure Ⅰ period(120 mmHg≤SBP<130 mmHg),high-normal blood pressure Ⅱ period (130 mmHg≤SBP<140 mmHg)and hypertension(SBP≥140 mmHg or SBP<140 mmHg but antihypertensive drug user). Multivariate logistic regression analysis was used to analyze the influence of different levels of systolic blood pressure on baPWV. Results 1)There were 3 132 males and 2 090 females in all the 5 222 participants with an average age of 55.1 years old. Their mean of baPWV was(1 587.57±400.71)cm/s,with the detection rates as 62%(baPWV≥1 400 cm/s). 2)The means of baPWV for the above groups of SBP were 1 322.19,1 456.27,1 544.78 and 1 827.77 cm/s, respectively,with detection rates of baPWV≥1 400 cm/s as 26.4%,49.3%,64.2% and 88.3%, respectively. 3)Results from the Multiple linear regression analysis revealed that β of SBP was 0.40,only ranking second,on age(0.48). 4)Data from the Multiple logistic regression analysis showed that after adjusting for age,gender and other risk factors,when compared to optimal SBP,factors as high-normal blood pressure Ⅰ period、high-normal blood pressure Ⅱ period and hypertension were risk factors for increasing baPWV,with OR values as 2.70(95%CI:2.20-3.32),4.56(95%CI:3.67-5.67)and 13.51(95%CI:10.87-16.78),respectively. Conclusion Higher SBP seemed an independent risk factor for the increase of baPWV.
