Background:The American Heart Association recently published an updated algorithm for quantifying cardiovascular health (CVH)—the Life’s Essential 8 score. We quantified US levels of CVH using the new score.Methods:We included individuals ages 2 through 79 years (not pregnant or institutionalized) who were free of cardiovascular disease from the National Health and Nutrition Examination Surveys in 2013 through 2018. For all participants, we calculated the overall CVH score (range, 0 [lowest] to 100 [highest]), as well as the score for each component of diet, physical activity, nicotine exposure, sleep duration, body mass index, blood lipids, blood glucose, and blood pressure, using published American Heart Association definitions. Sample weights and design were incorporated in calculating prevalence estimates and standard errors using standard survey procedures. CVH scores were assessed across strata of age, sex, race and ethnicity, family income, and depression.Results:There were 23 409 participants, representing 201 728 000 adults and 74 435 000 children. The overall mean CVH score was 64.7 (95% CI, 63.9–65.6) among adults using all 8 metrics and 65.5 (95% CI, 64.4–66.6) for the 3 metrics available (diet, physical activity, and body mass index) among children and adolescents ages 2 through 19 years. For adults, there were significant differences in mean overall CVH scores by sex (women, 67.0; men, 62.5), age (range of mean values, 62.2–68.7), and racial and ethnic group (range, 59.7–68.5). Mean scores were lowest for diet, physical activity, and body mass index metrics. There were large differences in mean scores across demographic groups for diet (range, 23.8–47.7), nicotine exposure (range, 63.1–85.0), blood glucose (range, 65.7–88.1), and blood pressure (range, 49.5–84.0). In children, diet scores were low (mean 40.6) and were progressively lower in higher age groups (from 61.1 at ages 2 through 5 to 28.5 at ages 12 through 19); large differences were also noted in mean physical activity (range, 63.1–88.3) and body mass index (range, 74.4–89.4) scores by sociodemographic group.Conclusions:The new Life’s Essential 8 score helps identify large group and individual differences in CVH. Overall CVH in the US population remains well below optimal levels and there are both broad and targeted opportunities to monitor, preserve, and improve CVH across the life course in individuals and the population.

美国成人和儿童的心血管健康状况使用美国心脏协会的新“生活必需品 8”指标：2013 年至 2018 年全国健康和营养检查调查 (NHANES) 的患病率估计

背景：美国心脏协会最近发布了一种量化心血管健康 (CVH) 的更新算法——Life's Essential 8 评分。我们使用新分数量化了美国的 CVH 水平。方法：我们纳入了 2013 年至 2018 年全国健康和营养检查调查中没有心血管疾病的 2 至 79 岁（未怀孕或住院）的个人。对于所有参与者，我们计算了总体 CVH 评分（范围，0 [最低] 到 100 [最高]），以及饮食、身体活动、尼古丁暴露、睡眠时间、体重指数、血脂、血糖、和血压，使用美国心脏协会公布的定义。样本权重和设计被纳入使用标准调查程序计算流行率估计和标准误差。CVH 评分跨年龄、性别、种族和民族、家庭收入和抑郁程度进行评估。结果：共有 23 409 名参与者，代表 201 728 000 名成人和 74 435 000 名儿童。使用所有 8 个指标的成年人的总体平均 CVH 得分为 64.7（95% CI，63.9-65.6），使用 3 个可用指标（饮食、身体活动和体重指数）的平均 CVH 得分为 65.5（95% CI，64.4-66.6） 2 至 19 岁的儿童和青少年。对于成年人，按性别（女性，67.0；男性，62.5）、年龄（平均值范围，62.2-68.7）以及种族和民族（范围，59.7-68.5）划分的平均 CVH 总分存在显着差异。饮食、身体活动和体重指数指标的平均得分最低。饮食（范围 23.8–47.7）、尼古丁暴露（范围 63.1–85.0）、血糖（范围 65.7–88.1）和血压（范围 49.5–84.0）的平均得分在不同人群中存在很大差异. 在儿童中，饮食评分较低（平均 40.6），并且在较高年龄组中逐渐降低（从 2 至 5 岁的 61.1 到 12 至 19 岁的 28.5）；社会人口统计学组的平均体力活动（范围，63.1–88.3）和体重指数（范围，74.4–89.4）得分也存在很大差异。结论：新的 Life's Essential 8 得分有助于识别 CVH 的较大群体和个体差异。美国人口的总体 CVH 仍远低于最佳水平，并且存在广泛和有针对性的机会来监测、保护和改善个人和人群整个生命过程中的 CVH。
