Abstract

Hypertension (HTN) is getting more prevalent in China, but the HTN's status in Guangxi remains unclear. Our study started from 2013 to 2015 and was dedicated to better acknowledging the status of HTN in Guangxi. The study enrolled 17,100 residents aged ≥ 15 years across Guangxi, from 2013 to 2015, using a stratified multistage random sampling method. Parameters including blood pressure (BP), height, and weight were measured by validated devices. HTN was defined as the average systolic BP (SBP) ≥ 140 mm Hg and/or average diastolic BP (DBP) ≥ 90 mm Hg, or any usage of antihypertensive medications within two weeks. The awareness, treatment, and control were defined as a self-reported history of HTN, a self-reported current usage of antihypertensive medications, and a BP lower than 140/90 mm Hg, respectively. The age and sex-standardized prevalence, awareness, treatment, control rates of HTN for the population aged ≥ 15 years in Guangxi were 15.80%, 16.48%, 11.99%, 3.62%, respectively. Prevalence and control rates were the same for men and women (P > 0.05), while women’s awareness and treatment rates were higher than those of men (P < 0.05). Zhuang nationality had a higher prevalence than Han (23.50% vs. 20.35%, P < 0.001), while Han had higher awareness, treatment, control rates (37.39% vs. 31.22%, 30.59% vs. 22.37%, 8.99% vs. 4.55%, individually, P < 0.05). HTN was prevalent in Guangxi, while the awareness, treatment, control rates were adverse. Region-specific strategies to intervene in HTN were needed.

Highlights

Hypertension (HTN) is one of the well-established modifiable risk factors for cardiovascular disease (CVD) and plays a critical role throughout the cerebrovascular disease and kidney disease progress[1,2,3]
A significant difference was observed between men and women for all characteristics except for ethnicity, mean Body Mass Index (BMI), and family history of HTN
Our study found that aged people tended to pay more attention to their blood pressure (BP) status and get more treatment of HTN, but control rates of HTN among different age strata were not significantly different

Summary

Introduction

Hypertension (HTN) is one of the well-established modifiable risk factors for cardiovascular disease (CVD) and plays a critical role throughout the cerebrovascular disease and kidney disease progress[1,2,3]. Strategies for the prevention and control of HTN must be established based on epidemiological characteristics of HTN among the local population. Very few studies had presented the status of HTN in Guangxi, and epidemiological characteristics of HTN in Guangxi remain unclear. Studies about epidemiological features of HTN in Guangxi are warranted. We investigated the status of HTN in the population aged 15 years or more of Guangxi, and several potential risk factors were detected as well, aiming to provide a peep at the basic epidemiological features of HTN and to shed light on the better control of it in Guangxi
