[Cardiovascular health status and related factors among adults aged 20-59 in 15 provinces of China in 2018].

Objective: To evaluate the cardiovascular health status of Chinese adults and explore the related influencing factors.

Methods: Adults aged 20-59 from the China Health and Nutrition Survey covering 15 provinces and cities in 2018 were selected as the study subjects. The average score of 8 health factors was calculated using the definition of the "Life's Essential 8" for cardiovascular health released by the American Heart Association in 2022. Cardiovascular health was classified according to the score. Multinomial logit model was used to analyze the impact of demographic characteristics on cardiovascular health.

Results: A total of 5977 subjects were included in this study. The total score of cardiovascular health was 73.62. The single factor analysis showed that sleep and physical activity scored higher(91.69 and 87.39, respectively), while blood pressure and diet scored lower(58.88 and 44.16, respectively). Clustering analysis found that only 0.45% of the people with full score of all eight indicators, The average number of full score indicators was 4.22, and the full score indicators were more among 20-44, female, college or above, and urban residents. In addition, the number of people with high, moderate and poor cardiovascular health status were 35.70%, 59.58% and 4.72%, respectively. Multinomial logit analysis showed that compared with low cardiovascular health status, the people with high in 45-59 were 66%(95% CI 0.25-0.45) lower than those in 20-44. Women with moderate and high were 9.93(95%CI 6.44-15.33) and 41.82(95% CI 26.87-65.08) times higher than men, respectively. The moderate cardiovascular health of the people with middle income was 1.47(95% CI 1.07-2.01) times higher than those with low income. People in the south with moderate and high were 31%(95% CI 0.53-0.91) and 38%(95% CI 0.46-0.82) lower than those in the north, respectively.

Conclusion: Adults in our country were in the moderate cardiovascular health. People aged 20-44, female, people with higher income and living in the north had better cardiovascular health.
