Stroke prevalence varies by race/ethnicity, as do the risk factors that elevate the risk of stroke. Prior analyses have suggested that American Indian/Alaskan Natives (AI/AN) have higher rates of stroke and vascular risk factors.
We included biyearly data from the 2011-2021 Behavioral Risk Factor Surveillance System (BRFSS) surveys of adults (age ≥18) in the United States. We describe survey-weighted prevalence of stroke per self-report by race and ethnicity. In patients with self-reported stroke (SRS), we also describe the prevalence of modifiable vascular risk factors.
The weighted number of U.S. participants represented in BRFSS surveys increased from 237,486,646 in 2011 to 245,350,089 in 2021. SRS prevalence increased from 2.9% in 2011 to 3.3% in 2021 (p<0.001). Amongst all race/ethnicity groups, the prevalence of stroke was highest in AI/AN at 5.4% and 5.6% in 2011 and 2021, compared to 3.0% and 3.4% for White adults (p<0.001). AI/AN with SRS were also the most likely to have four or more vascular risk factors in both 2011 and 2021 at 23.9% and 26.4% compared to 18.2% and 19.6% in White adults (p<0.001).
From 2011-2021 in the United States, AI/AN consistently had the highest prevalence of self-reported stroke and highest overall burden of modifiable vascular risk factors. This persistent health disparity leaves AI/AN more susceptible to both incident and recurrent stroke.
中风的患病率因种族/族裔而异，增加中风风险的危险因素也是如此。先前的分析表明，美洲印第安人/阿拉斯加原住民（AI/AN）的中风发病率和血管危险因素发病率较高。
我们纳入了美国成年人（年龄≥18 岁）在 2011-2021 年两年一次的行为风险因素监测系统（BRFSS）调查中的数据。我们按种族和族裔描述自我报告中风的调查加权患病率。在自我报告中风（SRS）患者中，我们还描述了可改变的血管危险因素的患病率。
BRFSS 调查中代表美国参与者的加权人数从 2011 年的 237486646 人增加到 2021 年的 245350089 人。SRS 的患病率从 2011 年的 2.9%增加到 2021 年的 3.3%（p<0.001）。在所有种族/族裔群体中，AI/AN 的中风患病率最高，2011 年和 2021 年分别为 5.4%和 5.6%，而白人成年人分别为 3.0%和 3.4%（p<0.001）。在 2011 年和 2021 年，AI/AN 中 SRS 的患者也最有可能有四个或更多的血管危险因素，分别为 23.9%和 26.4%，而白人成年人分别为 18.2%和 19.6%（p<0.001）。
在美国，从 2011 年到 2021 年，AI/AN 一直具有最高的自我报告中风患病率和最高的可改变血管危险因素总体负担。这种持续存在的健康差距使 AI/AN 更容易发生新发和复发性中风。
