We aimed to investigate the prevalence of stroke and related vascular risk factors in adult population aged 40 years and older in China. We conducted a prospective cross-sectional survey in nationally representative sample of 207323 individuals from all 31 Chinese provinces in 2013. Data were used to analyze the prevalence of stroke by age, sex, geographical regions and educational level. The age-standardized prevalence of stroke was significantly higher in men than in women in all age groups (P < 0.001). The age-standardized prevalence of stroke was significantly higher in rural than in urban residents among both men and women (P < 0.001). The prevalence of stroke was inversely associated with educational level. There were striking geographical variations in stroke prevalence in China with a higher prevalence of stroke in northern provinces as compared with southern provinces of the country. The age-standardized prevalence of hypertension, diabetes, dyslipidemia, atrial fibrillation and obesity in the Chinese population aged 40 years and older were 35.24%, 9.55%, 58.72%, 1.57% and 4.09%, respectively. Stroke and related vascular risk factors remains a major public threat in China and effective primary preventive strategies that aimed at reducing the burden of stroke and its risk factors are urgently needed.
我们旨在调查中国 40 岁及以上成年人中风和相关血管危险因素的流行情况。我们于 2013 年在全国 31 个省进行了一项具有代表性的前瞻性横断面调查，共纳入 207323 名个体。数据分析采用年龄、性别、地理区域和教育程度分层来分析中风的流行率。无论在哪个年龄段，男性中风的标准化流行率均显著高于女性（P<0.001）。无论男性还是女性，农村居民的中风标准化流行率均显著高于城市居民（P<0.001）。中风的流行率与教育程度呈负相关。中国的中风流行情况存在显著的地域差异，与南部省份相比，北部省份的中风流行率更高。中国 40 岁及以上人群中高血压、糖尿病、血脂异常、心房颤动和肥胖的标准化流行率分别为 35.24%、9.55%、58.72%、1.57%和 4.09%。中风和相关血管危险因素仍然是中国面临的主要公共卫生威胁，迫切需要采取有效的初级预防策略来降低中风及其危险因素的负担。
