Objective: To assess the cardiovascular health status of adults in China by using the "Life's Essential 8" score, and provide reference for the development and improvement of cardiovascular disease prevention and control policies and measures. Methods: Chronic Disease and Nutrition Surveillance was conducted in 298 counties/districts in 2015 in 31 provinces (autonomous regions, municipalities) across China, multi-stage stratified cluster random sampling was used to select 45 households in each village or neighborhood, and 20 households were further selected to conduct dietary surveys. In this study, a total of 70 093 adults aged ≥20 years who completed the dietary survey and had complete information were included, their cardiovascular health status were assessed by using the "Life's Essential 8" score, a cardiovascular health scoring standard released by the American Heart Association in 2022. All results were adjusted using complex design-based sampling weights to achieve a better estimate of the population. Results: In 2015, the overall cardiovascular health score of Chinese adults aged ≥20 years was 73.3±12.6, the score was significantly higher in women (77.9±11.6) than in men (68.7±11.8), and higher in urban area (74.5±12.8) than in rural area (71.9±12.2), the differences were significant (P<0.001). It was estimated that about 0.25% (95%CI: 0.16%-0.33%) of adults in China had cardiovascular health score of 100, and 33.0% (95%CI: 31.6%-34.3%), 63.2% (95%CI: 62.1%-64.3%), and 3.9% (95%CI: 3.5%-4.2%) of adults had high, moderate and low cardiovascular health scores, respectively. The proportion of those with high cardiovascular health scores was relatively low in men, those with low education level, those with low income, those living in rural areas, and those living in southwest China (P<0.001). Of the eight factors, diet had the lowest mean score (46.0, 95%CI: 44.7-47.3), followed by blood pressure (59.4, 95%CI: 58.2-60.6) and tobacco exposure (61.4, 95%CI: 60.6-62.2). Conclusions: The cardiovascular health status of two-thirds of adult population in China needs to be improved. Diet, tobacco exposure, and blood pressure are the factors affecting the cardiovascular health of Chinese population, to which close attention needs to be paid, and men, rural residents, and those with lower socioeconomic status are key groups in cardiovascular health promotion.
目的： 以“生命八要素”评分法评估我国成年居民心血管健康状况，为制定和完善心脑血管疾病防控政策和措施提供参考。 方法： 2015年中国成人慢性病与营养监测在全国31个省（自治区、直辖市）298个监测县（区），采用多阶段分层整群随机抽样方法，在每个行政村/居委会抽取45户，并从中选取20户，对所有户中居民进行膳食调查。本研究将完成膳食调查、年龄≥20岁且相关信息完整的70 093人作为研究对象，采用美国心脏协会2022版心血管健康评分标准—“生命八要素”评估我国成年居民心血管健康状况。所有结果采用基于设计的复杂抽样加权调整。 结果： 2015年我国≥20岁居民心血管健康得分为73.3±12.6，女性（77.9±11.6）显著高于男性（68.7±11.8），城市（74.5±12.8）高于农村（71.9±12.2），组间差异均有统计学意义（P<0.001）。我国有0.25%（95%CI：0.16%~0.33%）成年居民的心血管健康评分为100分，较高、中等和较低心血管健康评分的居民分别占33.0%（95%CI：31.6%~34.3%）、63.2%（95%CI：62.1%~64.3%）和3.9%（95%CI：3.5%~4.2%）。男性、低文化程度、低家庭人均年收入、农村及西南地区中较高的心血管健康评分者的占比相对更低（P<0.001）。8项生命指标中，饮食的得分最低［46.0（95%CI：44.7~47.3）］，其次为血压［59.4（95%CI：58.2~60.6）］和烟草暴露［61.4（95%CI：60.6~62.2）］。 结论： 我国约三分之二的成年居民的心血管健康状况有待改善，饮食、烟草暴露和血压是需要重点关注和干预的影响我国居民的心血管健康的因素，男性、农村居民以及社会经济地位较低者是心血管健康促进的重点人群。.
