Trends in cardiovascular disparities are poorly understood, even as diversity increases in the United States.

To examine U.S. trends in racial/ethnic and nativity disparities in cardiovascular health.

Repeated cross-sectional study.

NHANES (National Health and Nutrition Examination Survey), 1988 to 2014.

Adults aged 25 years or older who did not report cardiovascular disease.

Racial/ethnic, nativity, and period differences in Life's Simple 7 (LS7) health factors and behaviors (blood pressure, cholesterol, hemoglobin A_1c, body mass index, physical activity, diet, and smoking) and optimal composite scores for cardiovascular health (LS7 score ≥10).

Rates of optimal cardiovascular health remain below 40% among whites, 25% among Mexican Americans, and 15% among African Americans. Disparities in optimal cardiovascular health between whites and African Americans persisted but decreased over time. In 1988 to 1994, the percentage of African Americans with optimal LS7 scores was 22.8 percentage points (95% CI, 19.3 to 26.4 percentage points) lower than that of whites in persons aged 25 to 44 years and 8.0 percentage points (CI, 6.4 to 9.7 percentage points) lower in those aged 65 years or older. By 2011 to 2014, differences decreased to 10.6 percentage points (CI, 7.4 to 13.9 percentage points) and 3.8 percentage points (CI, 2.5 to 5.0 percentage points), respectively. Disparities in optimal LS7 scores between whites and Mexican Americans were smaller but also decreased. These decreases were due to reductions in optimal cardiovascular health among whites over all age groups and periods: Between 1988 to 1994 and 2011 to 2014, the percentage of whites with optimal cardiovascular health decreased 15.3 percentage points (CI, 11.1 to 19.4 percentage points) for those aged 25 to 44 years and 4.6 percentage points (CI, 2.7 to 6.5 percentage points) for those aged 65 years or older.

Only whites, African Americans, and Mexican Americans were studied.

Cardiovascular health has declined in the United States, racial/ethnic and nativity disparities persist, and decreased disparities seem to be due to worsening cardiovascular health among whites rather than gains among African Americans and Mexican Americans. Multifaceted interventions are needed to address declining population health and persistent health disparities.

即使在美国多样性增加的情况下，人们对心血管差异的趋势也知之甚少。

考察美国在心血管健康方面的种族/民族和出生差异的趋势。

反复进行横断面研究。

NHANES（国家健康与营养检查调查），1988年至2014年。

25岁或以上未报告心血管疾病的成年人。

Life's Simple 7（LS7）健康因素和行为（血压，胆固醇，血红蛋白A _1c，体重指数，体育锻炼，饮食和吸烟）的种族/种族，出生日期和期间差异以及心血管健康的最佳综合评分（ LS7得分≥10）。

白人的最佳心血管健康率仍低于40％，墨西哥裔美国人为25％，非裔美国人为15％。白人与非裔美国人之间在最佳心血管健康方面的差距仍然存在，但随着时间的流逝逐渐减少。在1988年至1994年期间，具有LS7最佳得分的非洲裔美国人的比例比25至44岁的白人和8.0％的白人（CI为6.4％至6.5％）低22.8个百分点（95％CI为19.3至26.4个百分点）。 65岁或以上的人群降低了9.7个百分点）。到2011年至2014年，差异分别降至10.6个百分点（CI，7.4至13.9个百分点）和3.8个百分点（CI，2.5至5.0个百分点）。白人与墨西哥裔美国人之间的最佳LS7评分差距较小，但也有所降低。这些下降是由于所有年龄段和所有年龄段的白人的最佳心血管健康状况均下降所致：1988年至1994年以及2011年至2014年之间，具有最佳心血管健康状况的白人所占百分比下降了15.3个百分点（CI，11.1至19.4个百分点）。年龄在25至44岁之间的人，年龄在65岁或以上的人群为4.6个百分点（CI为2.7至6.5个百分点）。

仅研究了白人，非裔美国人和墨西哥裔美国人。

在美国，心血管健康状况有所下降，种族/族裔和出生率差异仍然存在，并且差异的减少似乎是由于白人心血管健康状况恶化，而非非洲裔美国人和墨西哥裔美国人的健康状况提高所致。需要采取多方面的干预措施来解决人口健康下降和持续的健康差距。
