Central rather than brachial pressures are stronger predictors of cardiovascular outcomes: A longitudinal prospective study in a Chinese population.

The purpose of this study was to assess the association of blood pressure (BP) measurements with the risk of cardiovascular disease (CVD) and examine whether central systolic BP (CSBP) predicts CVD better than brachial BP measurements (SBP and pulse pressure [PP]). Based on a cross-sectional study conducted in 2009-2010 with follow-up in 2016-2017 among 35- to 64-year-old subjects in China, we evaluated the performance of non-invasively predicted CSBP over brachial BP measurements on the first CVD events. Each BP measurement, individually and jointly with another BP measurement, was entered into the multivariate Cox proportional-hazards models, to examine the predictability of central and brachial BP measurements.

Interankle Systolic Blood Pressure Difference Is a Marker of Prevalent Stroke in Chinese Adults: A Cross-Sectional Study.

This cross-sectional study carried out from November 2014 to December 2014 aimed to determine whether the interankle systolic blood pressure (SBP) difference is an independent marker of prevalent stroke. Simultaneous four-limb blood pressure measurements (oscillometric devices) and calculated SBP difference between the lower limbs were collected from 1485 participants aged 35 years and older. Questionnaires about traditional stroke risk factors were completed.

The Association of Four-Limb Blood Pressure with History of Stroke in Chinese Adults: A Cross-Sectional Study.

Objective: We investigated the association of ankle-brachial blood pressure index (ABI), interarm blood pressure (BP) difference and interankle BP difference, obtained by simultaneous four-limb BP measurement, with history of stroke in a Chinese adult population.

Methods: This cross-sectional study included 1485 participants aged ≥35 years in the framework of the China Hypertension Survey. We performed simultaneous four-limb BP measurement using oscillometric devices with the participants in the supine position and calculated ABI and interarm/interankle BP differences between the 4 limbs.

[A 50-year study on the epidemiology of hypertension in Heilongjiang Province of China].

Objective: To assess the epidemiological characteristics of hypertension and its attributing factors in Heilongjiang province and establish a comprehensive basis for the prevention and control of hypertension in this region.

Methods: Using the stratified chunk method, a survey lasting 50 years was conducted on a sample of 299 677 (including 158 782 males and 140 895 females) patients, aged 15 and above, residing in both rural and urban areas of Heilongjiang province from 1958 to 2007. Both blood pressure measurement and analysis on attributing factors of hypertension were carried out in 1958, 1979, 1991, 1999 and 2007.

[Prevalence and risk factors of prehypertensive status in people from the rural area of Lanxi county, Heilongjiang province].

Objective: To access the prevalence of prehypertensive stage and its associated risk factors in rural inhabitants from Lanxi county in Heilongjiang province.

Methods: Through cluster multistage and random sampling methods, local people aged > or = 15 years old in Lanxi county were selected. A survey on blood pressure and associated risk factors was carried out.

[Prevalence, awareness, treatment, and risk factors of hypertension in Harbin, Heilongjiang Province].

Objective: To investigate the prevalence, rates of awareness, treatment, and control, and risk factors of hypertension among the residents in Harbin, Heilongjiang Province.

Methods: 5523 residents, 2325 males and 3198 females, aged 15 and over, underwent questionnaire survey to understand their general conditions, history of present disease, awareness of disease, treatment, working condition, etc, and measurement of blood pressure (BP), height, body mass, and serum glucose and triglyceride.

Results: The no-standardized prevalence of hypertension was 31.

Hypertensive epidemiology in Heilongjiang Province in China.

Objective: To assess the epidemiology features of hypertension in Heilongjiang Province, China.

Methods: From 1959 to 1999, 289,157 people in total, ages > or = 15-year old (male 154,091, female 135,066) were investigated four times by a stratified chunk method in rural and urban areas in Heilongjiang Province. After a staff training program, this survey on blood pressure and risk factors was carried out under a worldwide uniform protocol with standardized method and interrelated quality control regulation.
