Stroke is currently the leading cause of death in China; however, the past decade has produced no new epidemiological studies of stroke. Therefore, the current study aimed to compare the prevalence and risk factors of stroke between 2010 and 2019.
A comparative study was used to analyze the prevalence of risk factors for stroke in a population aged 65 years or older between 2010 and 2019. Demographic characteristics, risk factors, medical history, and other clinical characteristics were collected for all participants via door-to-door interviews and inpatient hospital records.
The standardized prevalence of stroke was 7.9% in 2010 and 14.2% in 2019 (p < 0.001). The prevalence of stroke was significantly higher in men than in women (p < 0.05) for all age groups. The risk factors of stroke were being male, hypertension, and diabetes mellitus in both 2010 and 2019. When comparing the risk factors between 2010 and 2019, these risk factors were statistically significantly more strongly associated with stroke in 2019 than in 2010.
The current study suggests that the prevalence of stroke increased nearly by twofold in a population aged 65 years or older within the past 10 years. Hypertension, diabetes mellitus, and being male were the primary risk factors. In addition, these factors were more significantly associated with stroke in 2019 compared to 2010.
中风目前是中国的首要死因；然而，过去十年间尚未有新的中风流行病学研究。因此，本研究旨在比较2010年至2019年间中风的患病率及危险因素。
采用一项对比研究分析2010年至2019年间65岁及以上人群中风危险因素的患病率。通过逐户访谈和住院病历收集所有参与者的人口统计学特征、危险因素、病史及其他临床特征。
2010年中风的标准化患病率为7.9%，2019年为14.2%（p<0.001）。各年龄组中，男性中风患病率均显著高于女性（p<0.05）。2010年和2019年中风的危险因素均为男性、高血压和糖尿病。比较2010年和2019年的危险因素时，这些危险因素在2019年与中风的关联在统计学上比2010年更强。
本研究表明，在过去10年中，65岁及以上人群中风患病率几乎增加了两倍。高血压、糖尿病和男性是主要危险因素。此外，与2010年相比，这些因素在2019年与中风的关联更显著。
