Data on prevalence of atrial fibrillation and its association with stroke in low-, middle-, and high-income regions of China

Abstract

Data presented in this article are supplementary material to our research article entitled " Prevalence of Atrial Fibrillation in Different Socioeconomic Regions of China and Its Association with Stroke: Results from a National Stroke Screening Survey" (Wang et al., 2018) [1]. This data article summarizes previous studies of Atrial Fibrillation (AF) prevalence in China, and estimates the association between AF and stroke in different socioeconomic regions of China through a national survey.

Value of the Data

• •These data will be of value for studies on comparing the epidemiological characteristics of AF in China.
• •The data provides information on determinants of stroke in Low-, Middle-, and High-Income Regions of China.
• •The data demonstrate that socioeconomic status should be taken into account by policymakers in relation to the prevention and control of AF related stroke.

2. Experimental design, materials, and methods

The data of our study was from the China National Stroke Screening and Prevention Project (CNSSPP) in 31 provinces (except Tibet) in mainland China from October 2014 to November 2015. A total of 726,451 residents (386,975 women and 339,476 men) were included after the primary data cleaning. Socioeconomic regions were classified as low, middle, and high level according to the tertiles of per capita disposable income of households by regions in 2014 [14]. Data on demographic information, lifestyle risk factors, medical history, and a family history of stroke were collected through face-to-face interviews by a trained staff. We searched PUBMEN to identify population-based studies that reported prevalence of AF in China, and summarized findings in Table 1.

Stepwise logistic regression models were used to estimate the association between AF and stroke in different socioeconomic regions after adjusting for age, sex, location, overweight or obesity, smoking, drinking, physical inactivity, hypertension, diabetes, dyslipidemia, and a family history of stroke. Statistical analyses were performed by using SAS 9.3 for Windows (SAS Institute Inc., Cary, NC, USA), and in the two-tailed tests, a P value < 0.05 was considered statistically significant.
